Slide 50 introduces the concept of the **Attention Mechanism**, a foundational technique in modern generative AI models like Transformers. Attention allows models to weigh the importance of different parts of an input sequence when generating predictions, enabling more context-aware and coherent responses.
Represents the item seeking information from other parts of the sequence.
Represents the identity of information stored in each element.
The actual information retrieved based on the similarity between Query and Key.
Generate Q, K, V
Model transforms input embeddings into Query, Key, and Value vectors.
Compute Scores
Similarity between Query and all Keys is calculated.
Softmax Weights
Scores become probabilities representing importance.
Weighted Output
Values are combined using the weights to produce context-rich output.
Enables models to understand long-range dependencies in text such as pronouns and references.
Allows alignment between words across languages with high accuracy.
Vision Transformers apply attention across image patches for detailed understanding.
Provides coherent and contextually relevant responses in chat models.
It lets models focus on the most relevant parts of the input, enabling deeper understanding and more accurate generation.
Most state-of-the-art generative models—including GPT, LLaMA, and Vision Transformers—rely heavily on attention.
It provides dynamic, context-sensitive memory, improving over older fixed-memory architectures.
