Definizione di un LLM

Natural Language Processing (NLP) è la tecnologia che permette ai computer di comprendere, interpretare e generare il linguaggio umano in modo significativo. Questa tecnologia è spesso impiegata in applicazioni come i servizi di traduzione e i chatbot. I Large Language Models (LLM) sono una sottoclasse dell’NLP che genera risposte testuali simili a quelle umane, rendendoli fondamentali in molte aree della tua vita, dall’assistenza clienti all’istruzione personalizzata fino all’intrattenimento.

Exercise 3: LLM nel panorama dell'AI Exercise 4: Applicazioni di AI vs. LLM Exercise 5: Applicazioni nel mondo reale Exercise 6: Applicazioni aziendali Exercise 7: Applicazioni multimodali Exercise 8: Automatizza le attività basate sui dati Exercise 9: Sfide del language modeling Exercise 10: Cosa può fare un language model?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.
