- Remove platform-specific code (ARM_MATH_CM33, XMOS __XS3A__, std::printf) - Add set_output()/set_outputs()/add_example() API for programmatic training - Fix release build crash: side effect inside assert() for loss function init - Replace fake smoke test with real convergence tests (5 tests, all pass) - Rewrite example to demonstrate actual training with real output - Update README, CHANGELOG, and extraction plan to match reality

# Changelog
|
|
|
|
All notable changes to NISPS Core will be documented in this file.
|
|
|
|
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
|
|
|
|
## [0.2.0] - 2026-02-08
|
|
|
|
### Added
|
|
- `set_output()` / `set_outputs()` methods for programmatic output control
|
|
- `add_example()` method for adding training pairs without interactive workflow
|
|
- Real training convergence tests (identity mapping, multi-output)
|
|
- Working example with actual training (`examples/simple_mapping.cpp`)
|
|
|
|
### Fixed
|
|
- Release build crash: loss function pointer not initialized due to side effect inside `assert()` (mlp_impl.hpp)
|
|
- Removed ARM CMSIS-DSP conditional code from node.hpp (`ARM_MATH_CM33`)
|
|
- Removed XMOS `__XS3A__` conditional attributes from utils.hpp and loss.hpp
|
|
- Removed `std::printf` logging from dataset_impl.hpp (use IML logger callback instead)
|
|
|
|
### Changed
|
|
- README updated to document new APIs and remove false claims
|
|
- CHANGELOG rewritten to accurately reflect library state
|
|
|
|
## [0.1.0] - 2026-02-08
|
|
|
|
### Added
|
|
- Initial extraction from MEMLNaut-NISPS firmware
|
|
- Header-only C++20 library structure
|
|
- Core IML (Interactive Machine Learning) interface
|
|
- MLP (Multi-Layer Perceptron) neural network implementation
|
|
- Dataset management with replay memory support
|
|
- Training and inference modes
|
|
- Logging callback support
|
|
- CMake build system for tests
|
|
|
|
### Changed
|
|
- Converted from Arduino/RP2040 embedded code to platform-agnostic C++
|
|
- Updated to C++20 (required for std::span)
|
|
- Converted to header-only implementation pattern
|
|
- Added `nisps` namespace to all code
|
|
|
|
### Removed
|
|
- Arduino and RP2040 dependencies
|
|
- Serial debugging (replaced with optional callbacks)
|
|
- SD card save/load functionality
|
|
- Audio synthesis code (nisps-core is control-only)
|
|
|
|
### Migration from MEMLNaut-NISPS
|
|
If you're using the old embedded IMLInterface class:
|
|
```cpp
|
|
// Old (embedded):
|
|
IMLInterface iml(n_inputs, n_outputs);
|
|
|
|
// New (nisps-core):
|
|
nisps::IML<float> iml(n_inputs, n_outputs);
|
|
```
