Artificial Brain
In this exciting chapter, we dive into the fascinating world of large language models (LLMs) by drawing parallels with the human brain. We'll explore how these sophisticated AI systems process information and generate meaningful responses.
Imagine a complex network of interconnected neurons working together to understand and respond to text inputs. Just like in your own mind, LLMs take in vast amounts of data, break it down into manageable pieces, assign numerical values (embeddings), and pass this information through layers of artificial neurons.
Let's walk through the key components:
- Input Layer: This is where raw input data enters the system.
- Hidden Layers: These layers process the data, learning intricate patterns and features.
- Output Layer: The final layer produces the model’s predictions or responses.
We'll also delve into essential concepts like forward propagation (how data flows through the network) and backpropagation (how the network learns from its mistakes). Plus, we’ll introduce activation functions that add complexity to the learning process and transformers with self-attention mechanisms that make LLMs so powerful in understanding context.
Join us as we unravel the mysteries behind these incredible AI systems!
