Let’s delve into the mathematical foundations of Neural Language Models (NLMs) , which form the basis for modern Large Language Models (LLMs) : Representation Learning : NLMs aim to learn meaningful continuous representations (also known as embeddings ) for words or tokens. Each word is mapped to a high-dimensional vector in a continuous space. These embeddings capture semantic relationships and contextual information. Feedforward Neural Networks (FNNs) : The simplest neural model consists of a single hidden layer with nonlinear activation functions. Given an input (word embedding), the network computes a hidden representation using weights and biases. The output layer predicts the next word or token. Recurrent Neural Networks (RNNs) : RNNs handle sequential data by maintaining hidden states across time steps. Each time step processes an input (word embedding) and updates the hidden state. RNNs suffer from vanishing gradients and struggle with long...
