Tutorials

The tutorials walk you through complete, runnable examples that demonstrate how to use PyHDC to solve real problems. Each tutorial introduces new concepts progressively, so reading them in order is recommended for beginners.

Recommended order

#	Title	Audience	What you will learn
1	Tutorial 1: Encoding Text for Classification	Beginner	Codebooks, n-gram encoding, class prototypes, similarity-based classification
2	Tutorial 2: Associative Memory with Key-Value Binding	Beginner-Intermediate	Key-value binding, record construction, noisy query, capacity limits
3	Tutorial 3: GPU-Accelerated HDC with PyTorch	Intermediate	PyTorch backend, GPU encoding, batched operations, performance profiling
4	Tutorial 4: (Sparse) Binary Encodings (BSC and BSDC)	Intermediate	BSC, BSDC density control, BSDC_THIN, sequence encoding, similarity remapping
5	Tutorial 5: Implementing a Custom Encoding	Intermediate-Advanced	Subclassing Encoding, EncodingSpec, wiring components, custom inverse / permute / normalize
6	Tutorial 6: Custom Generators and Reproducibility	Intermediate-Advanced	Seeded generators, generator families, reproducibility, custom generator subclass

Tutorials 3-6 are independent of each other: you can read them in any order after completing Tutorials 1 and 2.
