Alter, Extract, Scrape, Process, Generate, Predict, Understand, Visualize TL; DR: In order to do all the challenging tasks he or she is supposed to do, a data scientist uses just like a mechanic would. But which ones are currently among the most essential? Let's take a quick look at 's essential data science tools: Matlab, Excel, Tableau and The Natural Learning Toolkit. tools 2019 1. Matlab MATLAB doesn't need an introduction, but will get one anyway. The multi-paradigm numerical computing environment (quite the tongue breaker) . It facilitates algorithmic implementation, matrix functions and modeling of data. In data science, MATLAB is used for both fuzzy logic and neural networks. Besides it's graphics library, it's also used in image and signal processing making it quite the versatile tool for data scientists. processes mathematical data Bonus: Matlab is easy to integrate and able to automate various tasks. Drawback: Closed-source 2. Excel In data science it is easy to forget the . And believe it or not, one of the most widely used tools to analyze data is Excel! end goal: solving problems Visualization and of course processing data? Excel, well, it's good at it. Often underestimated, it comes with various filters, slicers, tables and of course a variety of formulae. Bonus: Power it up with ToolPak! : As one would guess, it's more meant for small to non enterprise level in this context. Drawback 3. Tableau What better way to visualize a visualization tool like Tableau than Tableau? Focused on business intelligence, Tableau's core and strength lie with its ability to interface: database, analytical processing, and of course spreadsheet - but advanced. Bonus: Can geographical data and open source. Drawback: Free version is a bit more limited visualize 4. Natural Language Toolkit Wacky graphic? Exactly. NLP is not about visualization afterall. Able to deal with the development of it can help computers understand human language; Thanks to machine learning and algorithms. Widely used for processing techniques such as tokenization and parsing. Consists of a big collection of data for building machine learning models. statistical models Bonus: Python comes with a collection of libraries (short NLTK) Drawback: At times It's heavy and slippery, and it has a steep learning curve.
