Neural Network Foundations
What a neural network actually computes, why the nonlinearity is the whole trick, and how the weights learn.

From RNNs and LSTMs to self-attention — the architecture behind every modern LLM.
This is the real simulation from the module. No account needed.
A suggestion, never a lock — you can start here.
Every lesson's title and summary is public. The lessons themselves open once you own the track.
Every lesson in Introduction to Deep Learning & Neural NetworksProcessing sequences one step at a time, and why that is hard to train on long sequences.
Query, key, value — every token decides which other tokens it needs to look at.
Multi-head attention, positional encodings, and the block stacked inside every LLM.
What a neural network actually computes, why the nonlinearity is the whole trick, and how the weights learn.
Optimizers, learning-rate schedules, initialisation, normalisation and regularisation — what makes training actually converge.
Tensors, autograd, nn.Module, DataLoader and GPU training — enough PyTorch to work on your own.
Convolution, pooling and CNN architectures — why weight sharing makes images learnable.
