Deep Learning with CNTK and F#

Talkat NDC Sydney 2019 · 2019-10-14..10-18· [machine-learning, python]
slides:none on file

Shows concrete use of CNTK .NET API from F# to train small models: a toy 64‑image classifier and a 5,000‑image handwriting model (500‑image test set yields 9 mistakes ≈ 4.5% error). Uses tensors, parameters, sigmoid loss and stochastic gradient descent, inspects learned 8x8 weight maps that match expected digit strokes, and builds a readable sequential model DSL (convolutions + pooling) because the raw C++/C# bindings are verbose. Runs on CPU, trains to low loss, and saves interoperable models.
