What is Model size and Parameter size in AI

In this engaging and informative lecture, Mr. Gyula Rabai explains the concept of parameter size in large language models and its critical role in predicting words and understanding language. If you've ever been curious about how artificial intelligence systems like Chat GPT or other language models work, this is the perfect explanation for you.

What you'll learn in this lecture:

What Does Parameter Size Mean?
Mr. Rabai explains the technical term "parameter size" in simple terms. It refers to the number of numerical values a model uses to predict the next word in a sentence. The more parameters a model has, the more data it can process and the more accurate its predictions can be.

How Language Models Work:
Through a practical example using the phrase "Hello, World," you'll learn how models are trained to predict the next word in a sequence. These predictions are based on patterns learned from vast amounts of text data.

Real-Life Example of Parameters in Action:
Using "cat" as an example, Mr. Rabai illustrates how numerical parameters represent the meaning of words. For instance: A "cat" can be represented with just two numbers: one for the amount of fur and one for the number of legs. But if more parameters are available, we can include more details, such as a cat having a tail, a head, and other defining features, making the representation much richer and more accurate.

Why Bigger Models Perform Better:
Learn why smaller models (e.g., 1 billion parameters) might struggle to capture the complexity of language, while larger models (e.g., 400 billion parameters) can handle the intricacies of human language and even represent the entire complexity of the internet's text data.

Implications for AI Development:
Discover why choosing a large language model with a higher parameter count is essential for building systems that can produce accurate, meaningful, and context-aware results.
