Self vs. multi-head attention

Sei un data analyst in un team di sviluppo AI. Il tuo progetto attuale prevede di comprendere e implementare i concetti di self-attention e multi-head attention in un modello linguistico. Considera le seguenti frasi tratte da un insieme di dati di conversazioni.

A: "The boy went to the store to buy some groceries."

B: "Oh, he was really excited about getting his favorite cereal."

C: "I noticed that he gestured a lot while talking about it."

Stabilisci se queste frasi si analizzano meglio concentrandosi sulle relazioni all'interno dei dati di input (self-attention) o prestando attenzione contemporaneamente a molteplici aspetti dei dati di input (multi-head attention).

The AI landscape is evolving rapidly, and Large Language Models (LLMs) are at the forefront of this evolution. This chapter examines how LLMs are advancing the development of human-like artificial intelligence and transforming industries through their numerous applications. You will explore the challenges and complexity associated with language modeling.

Exercise 1: The rise of LLMs in the AI landscape Exercise 2: Definition of an LLM Exercise 3: LLMs in the AI landscape Exercise 4: AI vs. LLM applications Exercise 5: Real-world applications Exercise 6: Business applications Exercise 7: Multimodal applications Exercise 8: Automate data-driven tasks Exercise 9: Challenges of language modeling Exercise 10: What can a language model do?Exercise 11: Single vs. multi-task learning

This chapter emphasizes the novelty of LLMs and their emergent capabilities while outlining various NLP techniques for data preparation. You will learn the challenges of training LLMs and how fine-tuning can effectively address them. You will also understand how N-shot learning techniques enable efficient adaptation of pre-trained models when faced with limited labeled data.

Exercise 1: Novelty of LLMs Exercise 2: Problem solving with LLMs Exercise 3: Traditional models vs. LLMs Exercise 4: Generalized overview of NLP Exercise 5: Data preparation Exercise 6: Text preprocessing and representation Exercise 7: Word embeddings over bag-of-words Exercise 8: Fine-tuning Exercise 9: Challenges in building LLMs Exercise 10: Adapt a pre-trained model Exercise 11: Pre-trained or fine-tuned?Exercise 12: Learning techniques Exercise 13: Fine-tune a model Exercise 14: N-shot learning

In this chapter, you will learn about the fundamental building blocks of training an LLM, such as pre-training techniques. You'll also gain an intuitive understanding of complex concepts like transformer architecture, including the attention mechanism. The chapter discusses an advanced fine-tuning technique and summarizes the training process to complete an LLM.

Exercise 1: Elementi fondamentali per addestrare gli LLM Exercise 2: Linguaggio mascherato Exercise 3: Predici la parola successiva Exercise 4: Costruire da zero Exercise 5: Introduzione al transformer Exercise 6: Relazioni tra parole distanti Exercise 7: Componenti del transformer Exercise 8: Meccanismi di attention Exercise 9: Focus della multi-head attention Exercise 10: Self vs. multi-head attention
