ML Engineer Track
The production-minded sequence: solid fundamentals, training dynamics, evaluation, and the systems math behind serving models. You will move from standard scalers and loss functions to backprop, model diagnostics, and memory accounting. Built for engineers who ship models, not just notebooks.

Before you start
1Data Hygiene
Reproducible splits and features: MSE, train/test splits, shuffled and stratified sampling, standardization, one-hot encoding, distances, and k-fold indices.

Stage checkpoint
0/2 to passA checkpoint is a short retrieval test drawn from this stage: solve 2 of 3 from memory to mark the stage complete. The stage stays open either way.

2Losses and Optimization
What training actually minimizes: MSE and BCE gradients, gradient-descent steps, SGD updates, Xavier initialization, bootstrap sampling, and a full Adam update.

4Neural Systems and Cost
The deep-learning end of engineering: vocabulary mapping, backprop, softmax cross-entropy backward, a transformer encoder block, transformer parameter counts, and inference FLOP estimates.
