Curiously enough, Halloween could be a mysterious time, even in the world of finances. Have you ever heard of the bullish "Halloween effect" in stocks and cryptocurrencies? It's a fascinating phenomenon that suggests that Some even like to sum it up with the catchy phrase, "Sell in May and Go Away," until Halloween rolls around again. Sounds like a spooky mystery, right? Well, let's dive a bit into this phenomenon. after every Halloween (October 31), these markets tend to perform their best until the following May. The Halloween strategy is all about timing the market, which goes against the traditional "buy-and-hold" strategy. It encourages investors to be fully invested in stocks from November through April and then stay out of stocks from May through October. It might sound like a bit of a ghost story, but there's some intriguing data to back it up. An intriguing story The origins of can be traced back to the United Kingdom, where the wealthy class used to leave the bustling city of London for their country estates during the summer. They often neglected their investment portfolios during this time and only returned to the markets in September. The idea of abandoning stocks in May became quite popular, giving rise to the saying, "Sell in May, go away, come again, St. Leger Day." this strategy In more recent times, researchers Sven Bouman and Ben Jacobsen examined stock performance from November to April and coined it the "Halloween Indicator." According to their observations, investors who follow this strategy, fully investing for one six-month period and staying out of the market for the other six months, could potentially enjoy the better part of an annual return with only half the exposure of year-round investors. So, does it really work? Well, historical data suggests that the Halloween strategy has been quite successful over the past half-century. In fact, during a five-year timeframe, the strategy of selling in May beat the market over 80% of the time. And when applied in over ten years, it was successful more than 90% of the time. The numbers seem to indicate that the months from November to April often yield stronger capital gains compared to the rest of the year. ** ** \But here's where it gets mysterious: no one has been able to pinpoint a single, definitive reason for this anomaly. Some speculate that market liquidity is influenced by investment professionals' summer vacations, while others believe that investor aversion to risk during the summer plays a role in the discrepancy in seasonal returns. However, it's not entirely clear whether these factors are the true cause. Halloween effect in crypto This pattern has also been observed in the past for Bitcoin and other cryptocurrencies, but it's not a strict rule. It’s only a matter of checking the total cryptocurrency market capitalization in recent years to discover it ( , in our case). From Halloween in 2015 to May 2016, the whole market increased by over 55%. In the same period between 2016 and 2017, the market cap increased by over 177%. on CMC Between 2018 (a bearish year) and 2019, the market decreased by 13%, and between 2019 and 2020 also declined by 1.5% in the same period. The Halloween effect came back in full force between 2020 and 2021, with an increase of over 457%. But the market decreased again by 34% between November 2021 and April 2022. Then, from Halloween 2017 to May 2018, the market increased again by over 127%. It’s not infallible, though. * *The last “Halloween period” (between November 2022 and April 2023) showed modest gains of 20% for the whole market. However, we can’t say that coins increased their price in this period (or before). This may be considered a good time to invest, but every project should be researched thoroughly on its own. all So, while the Halloween effect might be an interesting trend, it's always wise to approach investment decisions with caution and a long-term perspective, especially in such a rapidly changing market. In the meantime, can offer you a safe wallet to save in the long term with several cryptocurrencies, thanks to the . We must remember that cryptocurrency markets are highly volatile and influenced by various factors, and past performance doesn't guarantee future results.

Educational Byte: The Halloween Effect in Crypto and Stocks

THE FABLE OF THE CICADA AND THE ANT

Social Life in the Insect World by Jean-Henri Fabre, is part of the HackerNoon Books Series. You can jump to any chapter in this book here . THE FABLE OF THE CIGALE AND THE ANT CHAPTER I. THE FABLE OF THE CIGALE AND THE ANT Fame is the daughter of Legend. In the world of creatures, as in the world of men, the story precedes and outlives history. There are many instances of the fact that if an insect attract our attention for this reason or that, it is given a place in those legends of the people whose last care is truth. For example, who is there that does not, at least by hearsay, know the Cigale? Where in the entomological world shall we find a more famous reputation? Her fame as an impassioned singer, careless of the future, was the subject of our earliest lessons in repetition. In short, easily remembered lines of verse, we learned how she was destitute when the winter winds arrived, and how she went begging for food to the Ant, her neighbour. A poor welcome she received, the would-be borrower!—a welcome that has become proverbial, and her chief title to celebrity. The petty malice of the two short lines— Vous chantiez! j'en suis bien aise, Eh bien, dansez maintenant! DURING THE DROUGHTS OF SUMMER THIRSTING INSECTS, AND NOTABLY THE ANT, FLOCK TO THE DRINKING-PLACES OF THE CIGALE. As we see, reality completely reverses the action described by the fable. The shameless beggar, who does not hesitate at theft, is the Ant; the industrious worker, willingly sharing her goods with the suffering, is the Cigale. Yet another detail, and the reversal of the fable is further emphasised. After five or six weeks of gaiety, the songstress falls from the tree, exhausted by the fever of life. The sun shrivels her body; the feet of the passers-by crush it. A bandit always in search of booty, the Ant discovers the remains. She divides the rich find, dissects it, and cuts it up into tiny fragments, which go to swell her stock of provisions. It is not uncommon to see a dying Cigale, whose wings are still trembling in the dust, drawn and quartered by a gang of knackers. Her body is black with them. After this instance of cannibalism the truth of the relations between the two insects is obvious. Antiquity held the Cigale in high esteem. The Greek Béranger, Anacreon, devoted an ode to her, in which his praise of her is singularly exaggerated. "Thou art almost like unto the Gods," he says. The reasons which he has given for this apotheosis are none of the best. They consist in these three privileges: γηγενἡϛ, ἁπαθἡϛ, ἁναιμὁσαρκε; born of the earth, insensible to pain, bloodless. We will not reproach the poet for these mistakes; they were then generally believed, and were perpetuated long afterwards, until the exploring eye of scientific observation was directed upon them. And in minor poetry, whose principal merit lies in rhythm and harmony, we must not look at things too closely. Even in our days, the Provençal poets, who know the Cigale as Anacreon never did, are scarcely more careful of the truth in celebrating the insect which they have taken for their emblem. A friend of mine, an eager observer and a scrupulous realist, does not deserve this reproach. He gives me permission to take from his pigeon-holes the following Provençal poem, in which the relations between the Cigale and the Ant are expounded with all the rigour of science. I leave to him the responsibility for his poetic images and his moral reflections, blossoms unknown to my naturalist's garden; but I can swear to the truth of all he says, for it corresponds with what I see each summer on the lilac-trees of my garden. LA CIGALO E LA FOURNIGO. I. Jour de Dièu, queto caud! Bèu tèms pèr la Cigalo, Que, trefoulido, se regalo D'uno raisso de fio; bèu tèms per la meissoun. Dins lis erso d'or, lou segaire, Ren plega, pitre au vent, rustico e canto gaire; Dins soun gousiè, la set estranglo la cansoun. Tèms benesi pèr tu. Dounc, ardit! cigaleto, Fai-lei brusi, ti chimbaleto, E brandusso lou ventre à creba ti mirau. L'Ome enterin mando le daio, Que vai balin-balan de longo e que dardaio L'ulau de soun acié sus li rous espigau. Plèn d'aigo pèr la péiro e tampouna d'erbiho Lou coufié sus l'anco pendiho. Si la péiro es au frès dins soun estui de bos, E se de longo es abèurado, L'Ome barbelo au fio d'aqueli souleiado Que fan bouli de fes la mesoulo dis os. Tu, Cigalo, as un biais pèr la set: dins la rusco Tendro e jutouso d'uno busco, L'aguio de toun bè cabusso e cavo un pous. Lou siro monto pèr la draio. T'amourres à la fon melicouso que raio, E dou sourgènt sucra bèves lou teta-dous. Mai pas toujour en pas. Oh! que nàni; de laire, Vesin, vesino o barrulaire, T'an vist cava lou pous. An set; vènon, doulènt, Te prène un degout pèr si tasso. Mesfiso-te, ma bello: aqueli curo-biasso, Umble d'abord, soun lèu de gusas insoulènt. Quiston un chicouloun di rèn, pièi de ti resto Soun plus countènt, ausson la testo E volon tout: L'auran. Sis arpioun en rastèu Te gatihoun lou bout de l'alo. Sus tu larjo esquinasso es un mounto-davalo; T'aganton pèr lou bè, li bano, lis artèu; Tiron d'eici, d'eilà. L'impaciènci te gagno. Pst! pst! d'un giscle de pissagno Aspèrges l'assemblado e quites lou ramèu. T'en vas bèn liuen de la racaio, Que t'a rauba lou pous, e ris, e se gougaio, E se lipo li brego enviscado de mèu. Or d'aqueli boumian abèura sens fatigo, Lou mai tihous es la fournigo. Mousco, cabrian, guespo e tavan embana, Espeloufi de touto meno, Costo-en-long qu'à toun pous lou soulcias ameno, N'an pas soun testardige à te faire enana.

Lou marrit-pèu prend pèr escalo Uno patto e te monto, ardido, sus lis alo, E s'espasso, insoulènto, e vai d'amont, d'avau. II. Aro veici qu'es pas de crèire.

Me fai susa, lou fabulisto, Quand dis que l'ivèr vas en quisto De mousco, verme, gran, tu que manges jamai. De blad! Que n'en fariès, ma fisto! As ta fon melicouso e demandes rèn mai. Que t'enchau l'ivèr! Ta famiho A la sousto en terro soumiho, Et tu dormes la som que n'a ges de revèi; Toun cadabre toumbo en douliho. Un jour, en tafurant, la fournigo lou véi, De tu magro péu dessecado La marriasso fai becado; Te curo lou perus, te chapouto à moucèu, T'encafourno pèr car-salado, Requisto prouvisioun, l'ivèr, en tèms de neu. III. Vaqui l'istori veritablo Bèn liuen dôu conte de la fablo. Que n'en pensas, canèu de sort! —O rammaissaire de dardeno Det croucu, boumbudo bedeno Que gouvernas lou mounde emé lou coffre-fort, Fasès courre lou bru, canaio, Que l'artisto jamai travaio E dèu pati, lou bedigas. Teisas-vous dounc: quand di lambrusco La Cigalo a cava la rusco, Raubas soun bèure, e pièi, morto, la rousigas. So speaks my friend in the expressive Provençal idiom, rehabilitating the creature so libelled by the fabulist. Translated with a little necessary freedom, the English of it is as follows:— I. Fine weather for the Cigale! God, what heat! Half drunken with her joy, she feasts In a hail of fire. Pays for the harvest meet; A golden sea the reaper breasts, Loins bent, throat bare; silent, he labours long, For thirst within his throat has stilled the song. A blessed time for thee, little Cigale. Thy little cymbals shake and sound, Shake, shake thy stomach till thy mirrors fall! Man meanwhile swings his scythe around; Continually back and forth it veers, Flashing its steel amidst the ruddy ears. Grass-plugged, with water for the grinder full, A flask is hung upon his hip; The stone within its wooden trough is cool, Free all the day to sip and sip; But man is gasping in the fiery sun, That makes his very marrow melt and run. Thou, Cigale, hast a cure for thirst: the bark, Tender and juicy, of the bough. Thy beak, a very needle, stabs it. Mark The narrow passage welling now; The sugared stream is flowing, thee beside, Who drinkest of the flood, the honeyed tide. Not in peace always; nay, for thieves arrive, Neighbours and wives, or wanderers vile; They saw thee sink the well, and ill they thrive Thirsting; they seek to drink awhile; Beauty, beware! the wallet-snatcher's face, Humble at first, grows insolent apace. They seek the merest drop; thy leavings take; Soon discontent, their heads they toss; They crave for all, and all will have. They rake Their claws thy folded wings across; Thy back a mountain, up and down each goes; They seize thee by the beak, the horns, the toes. This way and that they pull. Impatient thou: Pst! Pst! a jet of nauseous taste O'er the assembly sprinklest. Leave the bough And fly the rascals thus disgraced, Who stole thy well, and with malicious pleasure Now lick their honey'd lips, and feed at leisure. See these Bohemians without labour fed! The ant the worst of all the crew— Fly, drone, wasp, beetle too with horned head, All of them sharpers thro' and thro', Idlers the sun drew to thy well apace— None more than she was eager for thy place, More apt thy face to tickle, toe to tread, Or nose to pinch, and then to run Under the shade thine ample belly spread; Or climb thy leg for ladder; sun Herself audacious on thy wings, and go Most insolently o'er thee to and fro. II. Now comes a tale that no one should believe. In other times, the ancients say, The winter came, and hunger made thee grieve. Thou didst in secret see one day The ant below the ground her treasure store away. The wealthy ant was drying in the sun Her corn the dew had wet by night, Ere storing it again; and one by one She filled her sacks as it dried aright. Thou camest then, and tears bedimmed thy sight, Saying: "'Tis very cold; the bitter bise Blows me this way and that to-day. I die of hunger. Of your riches please Fill me my bag, and I'll repay, When summer and its melons come this way. "Lend me a little corn." Go to, go to! Think you the ant will lend an ear? You are deceived. Great sacks, but nought for you! "Be off, and scrape some barrel clear! You sing of summer: starve, for winter's here!" 'Tis thus the ancient fable sings To teach us all the prudence ripe Of farthing-snatchers, glad to knot the string That tie their purses. May the gripe Of colic twist the guts of all such tripe! He angers me, this fable-teller does, Saying in winter thou dost seek Flies, grubs, corn—thou dost never eat like us! —Corn! Couldst thou eat it, with thy beak? Thou hast thy fountain with its honey'd reek. To thee what matters winter? Underground Slumber thy children, sheltered; thou The sleep that knows no waking sleepest sound. Thy body, fallen from the bough, Crumbles; the questing ant has found thee now. The wicked ant of thy poor withered hide A banquet makes; in little bits She cuts thee up, and empties thine inside, And stores thee where in wealth she sits: Choice diet when the winter numbs the wits. III. Here is the tale related duly, And little resembling the fable, truly! Hoarders of farthings, I know, deuce take it. It isn't the story as you would make it! Crook-fingers, big-bellies, what do you say, Who govern the world with the cash-box—hey? You have spread the story, with shrug and smirk, That the artist ne'er does a stroke of work; And so let him suffer, the imbecile! Be you silent! 'Tis you, I think, When the Cigale pierces the vine to drink, Drive her away, her drink to steal; And when she is dead—you make your meal!

THE FABLE OF THE CIGALE AND THE ANT

THE DEAD-HOUSE

Language: An Introduction to the Study of Speech: Chapter 8

Recently, I got a chance to attend GitHub Satellite, the conference which brings big ideas and memorable content to cities around the world. From the latest GitHub product news to hands-on workshops, GitHub Satellite brings together thousands of developers to explore what’s next. Me at Brandenburg Gate, Berlin It was a phenomenal experience attending the conference. I attended GitHub Satellite as a GitHub Campus Expert, India along with other 10 from different parts of the world. I reached Berlin well in advance of the event and had plenty of time to explore the city. So on the first day I took the Berlin tour and got to know about the stories related to all the historical buildings there. Me with Lieke Boon As all the campus experts build communities at their campus, it is very difficult for all of us to meet each other and events like these are a good opportunity to talk and get to know about each other. The day before satellite, we had a Campus Experts Meetup where everyone just talked with each other, ate good food and delivered their scheduled lightning talks. Also, I met super cool Lieke who is the Developer Program Manager for Campus Experts. Not to mention, sketch notes by Carlosgilmar left everyone amazed. Sketch Notes for the GitHub Campus Experts Meetup by Carlosgilmar The talks in the meetup consisted of talks from building communities to organising events, from dark patterns in a software to weird things javascript does. The next day morning, it was the showtime. The conference was at Kraftwerk in Berlin which was nearly half hour away from where I was staying. I reached nearly half an hour before the keynote, checked in myself, the GitHub staff at the registration desk handed over me a transparent neon tote bag with a limited edition sticker pack and notepad in it. It was amazing to see that all the details I filled while taking my ticket for the Satellite was inside my attendee card and while interacting with the sponsors, all I had to do was tap my card on their device to give my details to them. Nat Friedman on stage during his keynote Everyone was on time, no one wanted to miss Nat’s keynote. There was a surprise talk which would mark the closing of the GitHub Satellite, nobody knew what it was until Nat revealed it in his Keynote. Finally the clock struck 9:30 and it was time for the keynote to start. Nat came on the stage, welcomed everyone to Satellite and continued the keynote.The keynote was packed with a lot of feature announcements in the area of security, enterprise and community. Nat told that GitHub calls their 36 million developer users “GitHub home”. After telling about the open source community and that any project currently has an open source dependency, then came the first major breakthrough or should I say the most awaited surprise, Dr. Katie Bouman joined GitHub Satellite via satellite from Boston. Few minutes later, came another surprise, the core team behind the black hole image, Andrew, Kazu, Sarah, C.K, Roman and Lindy joined the keynote on stage. Surprise after surprise came another surprise, out of the 21000 contributors of the full dependency graph for the black hole image, the maintainers and core contributors to Numpy, Matplotlib, Scipy, Astropy, Pandas, Python, Cython, Kiwisolver etc. were attending GitHub Satellite. After all the surprise reveals, then came the turn for feature reveal, At the very first, Nat revealed the community contributors and dependent repository feature which lets one know that how many direct and indirect contributors are there to the project and also by how many people the project is used. GitHub ❤ Dependabot The security features were unveiled by Shanku Niyogi. Partnership with whitesource and dependabot being part of GitHub. Automated security vulnerability fixes via dependabot and security advisory were some of the keyhighlights for security features. Dana Lawson talked about the new features in GitHub Enterprise. Devon Zuegel announcing GitHub Sponsors Finally, towards the end, Devon Zuegel came up with the most lovable feature reveal for all, the GitHub sponsors. To sum up the keynote and the final best thing to be revealed, Nat announced GitHub matching fund i.e 200% fund transfer on sponsorship. After the keynote, there was a break and most of the people started networking. I had a good talk with the sponsors of Satellite, Circle CI, Travis, Whitesource and Snyk. The team from Microsoft Azure Devops was running a lab at the venue and also a demo for the azure pipelines. Throughout the day, I met many people and talked to them. It was great talking to all of them and knowing all the new stuff they had to share. I met the organiser of Slash Hackathon, Slash is a tech community of CODE University of Applied Sciences in Berlin. It is always fascinating meeting other student community leaders and knowing how they handle things and what aim they have for their community. Next, I got a chance to meet a lot of hubbers from professional services team, from product design team and other teams. I met the incredible Hector Alfaro, who then told me that he has worked closely with the Campus Experts program in its initial phase. And finally, I met the marvelous Nat Friedman and had a little talk with him about the keynote. Me with Nat Friedman The venue was filled with a lot of cool things to checkout. There was an octocat generator, but yes, it wasn’t any other octocat generator, the octocat generated over here were converted into stickers for you. Interconnected communities room was fascinating, it showed a visualisation of the GitHub followers, the best part about it was how it showed the interconnected communities. The visualisation was in the form of space, every user was a star but the user being checked out was the brightest of all and in the center. Now each follower following me has its set of followers. At the back of these stars, small dots can be seen at a distance representing the interconnection between the user being checked out and the user not following it. My GitHub follower visualisation In the conference, I attended Open Source for good session and the closing session “Into The Black Hole” taken by the black hole team. Many of the things from the talk were quite difficult to understand but still it provided me with a lot of new information about the complete process behind the black hole image. It was quite wonderful to know about why the black hole image looks like the way it is. The GitHub Satellite was over with a standing applause to the black hole team after their session. Then came the afterparty and later on the preparty for the Maintainerati unconference happening next day. During the afterparty, I saw something not seen till now, one of the person was DJing the programmer’s way using Haskell and setting up all the bpm for the music. I didn’t know how it worked but it was unbelievable to see it at first look. After it, all the campus experts clicked a picture and finally it was time to bid adieu to the GitHub Satellite. Next day it was time for the Maintainerati unconference organised by the GitHub Developer Relations team. The aim was to create an open space for all the developers to hangout, communicate as much as possible and discuss about the opensource issues and how to overcome them. I talked about how to get almost 100 people started with their first pull request and then discussed over what makes a contributor not to become a maintainer. I met Don Wilson here and he was also the space host where I talked about my topic. Don kept making the notes throughout the open space session of the communication happening and notes were basically more to point out the common problems every person face in opensource. Maintainerati Unconference After the Maintainerati, finally the 3 day conference extravaganza came to a halt. Those 3 days are the most memorable days I had till now and its difficult to forget them. It was real great to get so much of knowledge, ideas from each person and to know problems faced by each person in opensource. By talking to other experts, I had a good idea about how different communities have different issues and how they come over it and do different things according to their community. Hi, I am Anupam Dagar, an Information Technology undergraduate student from Indian Institute of Information Technology Allahabad. I am an opensource contributor and a full stack developer.

My experience attending GitHub Satellite 2019 in Berlin

In December 2017 I had an opportunity to discover the Kenyan based ICO and write up a on it. As sometimes happens, I develop an affinity for the person/company that I talked to when putting these articles together and in this case, I kept in contact with CEO Isaac Muthui. I would answer questions for him and point out information to him that would be helpful for his project. After a couple months he invited me to come and visit their company in Kenya, they were interested in my opinions on technology they were building. I agreed to come because, why not, a trip to Africa. I wasn’t compensated for the trip or for this article, but my expenses were covered, I mention that in the interest of full disclosure. What I discovered in Kenya and about Isaac and the goals for Nurucoin, got me thinking in some extremely big pictures. Nurucoin spotlight article Of the many things I did on the trip, one of them was to visit the village that Isaac was born in. This was about a 3 hour drive from Nairobi and the last 10 miles or so was on a dirt road that can only generously be called a road. Isaac’s mother still teaches at the school that he grew up in, the main difference is that they have paper now to take notes and do tests. When Isaac went to school there, up through 5th grade, they would do their tests in the dirt with their fingers due to lack of supplies. The buildings almost look like the result of a recent archeological dig, rather than a place of learning. The students have paper and books now, but as you can see in this picture, they are not in good shape. The children all wear uniforms to school, but just as when Isaac went to school, they are still without shoes. They walk between 1 and 5 kilometers each direction, each day in the dirt so that they can get an education, so determined to improve their lot in life. This is exactly what Isaac did, starting out in a village, living in a thatch hut, no shoes or supplies, taking tests in the dirt, he went on to university and got a degree in Computer Science. In addition, he holds a Diploma and Higher Diploma in Management Information Systems specializing in Data and Web Security and Computer Forensics. From those humble beginnings, Mr. Muthui has gone on to form 9 companies to follow his dream of helping improve life for his fellow Africans. While we drove, around, we talked a lot about Africa and the state of economic development. Isaac could rattle off the population numbers, GDP, standing in the world economic ratings, monetary conversion rates and just about anything you’d care to know about the African nations. His energy and passion for making Africa a hub for technological innovation is palpable. Mr. Muthuis passion now is Blockchain technology and his cryptocurrency and Nuruchain technology platform. Financial issues, such as volatile currencies and fluctuating exchange rates as well as government corruption and too many middlemen in between transactions in Africa, have led to an environment where you have a large population of destitute poor and then people who are wealthy and very little in between. In Kenya the natural resources are significant and there is no reason that they can’t be utilized in a less corrupt fashion so that more people can make more money. The work ethic is strong in Kenya and it is amazing how much effort people go through to better themselves, but there is also a propensity to get into a safe path, go to school, go to university, get a job with the government and do that till you die. There is no such thing a telecommuting which leads to unbelievable traffic problems in the cities, where it can literally take you an hour to travel 5 miles. The lost productivity is staggering from wasted time. Getting more people educated in skills that they can use remotely around the world, will bring more money into the economy and reduce the stress on their infrastructure. Nurucoin The goal for Nurucoin is to establish a digital currency that will initially be used in the system (similar to Amazon, but smaller) and set the groundwork for a cryptocurrency that can bypass the volatility and exchange rates that currently exist across Africa. In parallel will be the development of an enabling technology similar to Ethereum called Nurublock. This framework will allow other companies to more easily develop blockchain based technologies to solve other problems. Mr. Muthui intends to create training programs that can be deployed to help citizens learn about Blockchain generally and how to develop for Nurublock in particular. Blazebay The vision is huge and many people are getting on board with Mr. Muthui’s vision. While I was there, Kenyan government Minster for ICT called Isaac and setup a meeting to discuss what he was doing, the minister is very passionate about blockchain and getting Kenya to embrace blockchain technology. There are naysayers of course and people who didn’t think of it first are prone to try and tear it down, but there seems to be no stopping Isaac and the momentum he has been creating for Nurucoin. I feel honored to have been there as this was getting off the ground, it is going to be a game changer in Africa. When we look back in a few years at how it all started, we’re going to be amazed at where it is. Keep on eye on Nurucoin and Isaac Muthui.

For the box prompt, we use ground-truth bounding boxes as input prompts. 1-pt IoU denotes the oracle performance of one point by evaluating the intersection-overunion (IoU) of the predicted masks that best match ground truth. 1-box IoU denotes is similar to 1-pt IoU. More evaluation results are reported in Fig. 7, Fig. 8 and Fig. 9. Dataset details. A description of each dataset is given in Tab. 5. The iShape dataset has 6 subsets, including antenna, branch, fence, hanger, log and wire. This paper is available on arxiv under CC BY 4.0 DEED license.
