💎 This Week’s Sponsor 💎

In the age of AI, I see a future where everyone builds their own AI systems, be that your personal LLMs or your own personal developer like Devin.

Nonetheless, you’ll desperately need information on your competitors to drive better decisions. Or you might need data to evolve your skills and stay competitive in the labor market.

One way or another, you are going to need data.

Bright Data is the leading web platform to optimize your public data gathering and processing, from scraping data from the Internet at scale, to harnessing insights from your very own competitors, or identifying key market trends.

🤩 AI Research of the week 🤩

The moment we all saw Trevor playing chess with the mind, we knew something had changed.

A few days ago, Neuralink presented its first real patient testing its brain chip. The user played chess, or even Mario Kart.

Overall, an impressive and life-like demonstration of the hugely optimistic future that awaits people with severe disabilities like Trevor, who is a quadriplegic.

And while the exact intricacies of the system aren’t fully disclosed, what we know, combined with cutting-edge AI research in Brain-Computer Interfaces (BCIs) is more than enough to give us great insight and understanding of how Neuralink works.

Welcome to Pattern World

Whenever you see an AI product, no matter how complex or secretive it is, it all boils down to the same principle: finding patterns in data.

There are two ways of doing so: generative or discriminative.

Generative AI models

Although the definition is in the name, it’s not quite as obvious. Yes, generative models generate data, but I’m not here to state the evident but to help you understand how they truly work.

Simply put, generative models learn the distribution of the training data and sample from it. In other words, they figure out the statistical correlations in the data to maximize the likelihood of being capable of replicating it.

In essence, this is what ChatGPT is, a set of parameters that maximize the likelihood of generating data that is similar to the training data.

In practice, for a given sequence, they give you a statistically reasonable continuation of that sequence. In other words, “based on my training data, what is the set of next words more likely to be ‘similar’ to what I saw during training?”
