machaMochaLatte is a student research contributor focused on mathematics, artificial intelligence, scientific reasoning, and structured problem solving. Her writing examines technical ideas from the perspective of a student building deeper mathematical and engineering intuition, with particular interest in how foundational concepts connect to modern AI systems.
AI Foundations #14 explains how fine-tuning continues gradient-based training from pretrained weights, using narrower data to change model behavior without relearning language from scratch.
AI Foundations #12 assembles attention, residual connections, normalization, and MLP layers into the repeating Transformer block behind modern language models.
AI Foundations #10 connects embeddings to tokenization: how text is split into tokens, mapped to vocabulary IDs, and then looked up as learned vectors.
AI Foundations #8 explains backpropagation as repeated chain-rule bookkeeping that carries loss information backward through a neural network to every trainable parameter.
AI Foundations #4 explains tensors through shapes, axes, images, batches, model weights, and memory, without assuming you already know linear algebra or PyTorch.
A Whitby high school student explains how she uses ChatGPT for hints, error analysis, proofs, calculus, vectors, and practice without outsourcing the thinking.
