Today on AemonAlgiz, we delve into the intricate inner workings of large language models, peeling back the layers of complexity to reveal the magic that powers these digital marvels. From the foundational concepts like softmax and layer normalization to the fascinating world of tokenization, the journey begins with a quest to understand the very essence of how these models compute their output tokens. Softmax, with its knack for constraining values between 0 and 1, plays a crucial role in taming the wild fluctuations of intermediate states within these models, setting the stage for a symphony of computations.
Tokenization emerges as a pivotal step, where the creation of tokens breathes life into the model's understanding of language. Subword tokenization, a delicate dance between word-wise and character-wise approaches, strikes a balance that allows for flexibility in handling misspellings and diverse linguistic nuances. The subsequent journey into embedding spaces unveils a realm where tokens find their place in high-dimensional spheres, forming connections that guide the model in deciphering the intricacies of language. Positional encoding adds another layer of depth, providing the model with a sense of spatial awareness amidst the sea of tokens.
Attention takes the spotlight, transforming the model into a virtual problem-solving maestro akin to a human mind seeking context clues to unravel mysteries. Query, key, and value matrices become the tools of this digital detective, guiding it towards selecting the next token with finesse and precision. Multi-attention heads step into the arena, showcasing the power of parallel processing and enabling the model to tackle complex inputs with grace. Emergent weights, those enigmatic elements that hold the key to the model's performance, lurk beneath the surface, demanding careful handling to maintain the model's prowess. As the journey culminates in the intricate dance of computations leading to the final output tokens, the symphony of algorithms and data intertwines to create a masterpiece of modern technology.
