Unless you’ve been living under a rock, you’ve heard about . This language model has absorbed tremendous volumes of conversational text using the supervised learning and, at the fine-tuning stage, the reinforcement learning from human feedback (RLHF) approaches. OpenAI’s ChatGPT The generative AI solution can analyze input data and profoundly understand the written language. The smart tool can answer questions, summarize and translate text, produce articles on a given topic, write code, and much more. All you need is to . against 175 billion parameters provide ChatGPT with the right prompts OpenAI’s groundbreaking product is just one example of foundation models that transform as we know it. AI application development Foundation models disrupt AI development as we know it. Instead of training multiple models for separate use cases, you can now leverage a pre-trained AI solution to enhance or fully automate tasks across multiple departments and job functions. With foundation AI models like ChatGPT, companies no longer have to train algorithms from scratch for every task they want to enhance or automate. Instead, you only need to select a foundation model that best fits your use case — and fine-tune its performance for a specific objective you’d like to achieve. Foundation models are perfect for industries where training data can be too hard or expensive to acquire. These industries include , life science, biotechnology, and manufacturing, to name a few. healthcare What types of foundation AI models are there? Several types of foundation AI models are commonly used in business applications: are trained on a dataset that contains a mixture of labeled and unlabeled data. The goal is to use the labeled data to improve the model’s performance on the unlabeled data. AI experts turn to semi-supervised learning when training data is difficult to obtain or would cost your company an arm and a leg. This, for instance, may happen in medical settings where various healthcare IT regulations are enacted. Some common examples of semi-supervised models include pre-trained text document and web content classification algorithms. Semi-supervised learning models are fully trained on unlabeled datasets. They discover patterns in training data or structurize it on their own. Such models, among other things, could segment information into clusters based on the parameters they’ve uncovered in a training dataset. ML engineers turn to auto-encoders, K-Means, hierarchical clustering, and other techniques to create unsupervised machine learning solutions and improve their accuracy. Unsupervised learning models interact with their environment without specific training. When achieving a desired outcome — i.e., making a prediction the developers have hoped for — the models get rewarded. On the contrary, reinforcement learning models are penalized when making wrongful assumptions. The approach allows AI algorithms to make more complex decisions than their supervised and semi-supervised counterparts. An example of reinforcement learning in action would be autonomous vehicles or game-playing artificial intelligence like AlphaGo. Reinforcement learning models produce new data similar to the data they’ve been trained on. This data may include text, images, audio clips, and videos. The ChatGPT solution mentioned in the previous section belongs to this category of foundation AI models. Other examples of generative AI include the , which creates images based on descriptions written in natural language, and the video platform, which uses text-based inputs to produce video content. Generative AI models DALL-E 2 tool Synthesia.io can solve tasks other than they’ve been trained on. For instance, computer vision engineers may leverage pre-trained image classification algorithms for object detection. Or harness existing NLP solutions for more knowledge-intensive tasks, such as customer sentiment analysis. Some popular pre-trained machine learning solutions include OpenCV, a computer vision library containing robust models for object classification and image detection, and Hugging Face’s Transformers library offerings, such as generative pre-trained transformer (GPT) — i.e., a rich language model whose third generation (GPT-3) powers the ChatGPT service. Transfer learning models , unlike their task-orientated equivalents, literally learn to learn (no pun intended). Instead of devouring data to solve a specific problem, such models develop general strategies for problem-solving. This way, meta-learning solutions can easily adapt to new challenges while using their resources, such as memory and computing power, more efficiently. ML experts tap into meta-learning when training data is scarce, or a company lacks definitive plans regarding AI implementation in business. TensorFlow, PyTorch, and other open-source machine learning libraries and frameworks offer tools that allow developers to explore meta-learning techniques. And cloud computing providers like Google help ML experts and newbies train custom machine learning models using AutoML. Meta-learning models Depending on the specific application and the type of data you have, one foundation model may be more appropriate than another. And your company is free to choose between an open-source solution, which needs a bit of tweaking, or a ready-to-use third-party product — provided it meets your business targets. Top 3 reasons to leverage foundation AI models for your next project Compared to standalone, task-oriented machine learning models, foundation models help create reliable AI solutions faster and cheaper, with less data involved and minimal fine-tuning. And that's not to mention that, being trained on more data than a single organization could ever obtain, foundation models display high accuracy from day one. Below you will find a rundown of foundation AI models’ advantages: . Creating and deploying an AI solution requires considerable time and resources. For every new application, you need a separate well-labeled data set. And if you don’t have it, you’ll need a team of data experts to find, cleanse, and label that information. According to Dakshi Agrawal, CTO of IBM AI, foundation models help cut down on data labeling requirements by 10-200 times depending on a given use case, which translates into significant cost savings. On the business side, you should also consider the rising cloud computing expenses. Google, for instance, spent as much as $35 million to teach DeepMind to play Go. And while your AI project may not be half as ambitious, you in cloud server costs alone to get your AI app up and running. Another reason to use foundation models, such as generative AI solutions, is the opportunity to quickly prototype and test different concepts without investing heavily in R&D. Foundation models will help you implement AI faster, cheaper, and with fewer resources involved could easily spend $300,000 . As their name implies, AI foundation models can serve as a basis for multiple AI applications. Think about driving a car. Once you’ve got a driver’s license, you don’t need to pass the exam every time you buy another vehicle. Similarly, you can use a smaller amount of labeled data to train a general-purpose foundation model that summarizes texts to process domain-specific content. And foundation models possess “emergence” capabilities, too, which means that a model, once trained, may learn to solve problems it was not supposed to address or glean unexpected insights from training data. You can reuse foundation AI models to create different applications . Training one large machine learning model footprint as running five cars over their lifetime. Such a heavy carbon footprint stands in sharp contrast with the fact that 66% and 49% of businesses are and developing new climate-friendly services and products, respectively. With foundation AI models, you can train intelligent algorithms faster and utilize computing resources wisely — not the least thanks to the models’ architecture that takes advantage of hardware parallelism, executing several tasks simultaneously. Foundation AI models help achieve your company’s sustainability goals can have the same environmental increasing the efficiency of energy use Deemed “the future of AI,” foundation models lower the threshold for tapping into artificial intelligence and could potentially end the failed AI proof of concept cycle by helping businesses scale models across other use cases and company wide. But with every opportunity comes a challenge. Things to consider when using foundation models The only glaring drawback of foundation AI models is a . lack of explainability Large foundation models can use so much training data and have so many deep layers that it’s sometimes hard to determine how algorithms arrive at their conclusions. The black-box nature of foundation models leaves a backdoor for cybercriminals, too. Hackers can launch data poisoning attacks and introduce , further exacerbating artificial intelligence’s ethical issues. AI bias Technology companies should join forces with governments to set up infrastructure for public AI projects to avoid contention surrounding foundation AI models’ usage. AI vendors should also disclose what datasets they use and how they train their models. As Percy Liang, Stanford HAI faculty and computer science professor, , “We’re very much in the early days, so the professional norms are underdeveloped. It’s therefore imperative that we, as a community, act now to ensure that this technology is developed and deployed in an ethically and socially responsible fashion.” opined during his recent interview with Venture Beat What does it take to start using foundation models in your organization As someone who’s spent the last ten years helping companies implement AI systems, the ITRex team is witnessing a shift in artificial intelligence.
