CHANGELOG 

## [0.6.0] - 2026-04-11

### Fixed

- Fixed `random_perturbations/4` for 2D: positions were built as a tuple instead of a list of `{row, col}` pairs, causing a runtime `Protocol.UndefinedError`; also corrected `num_flips` to use total cell count instead of row count only

### Changed

- `load_ctm_data/2` for 2D now indexes all 8 dihedral-group symmetries (rotations and reflections) of each block, plus their bit-complements, reducing CTM cache misses



## [0.5.0] - 2026-01-24

### Added

- Implemented the Minimal Information Loss algorithm for feature selection and dimension reduction.



## [0.4.0] - 2025-09-13

### Added

- Backend could be selected for BDM. The default is CTM, Lempel–Ziv Complexity (LZC) is an option. Useful for large 2D matrices



## [0.3.1] - 2025-08-29

### Fixed

- Added missing CTM values



## [0.3.0] - 2025-08-29

### Changed

- Replaced the placeholder CTM values with real ones

### Removed

- Removed the incomplete implementation of the `:recursive` boundary condition

- Removed `BDM.Utils.normalize/2`



## [0.2.1] - 2025-08-27

### Added

- Added new simple 3x3 pattern type: `[[1, 0, 0], [0, 0, 0], [0, 0, 0]]` and `[0, 0, 0], [0, 0, 0], [0, 0, 1]]`



## [0.2.0] - 2025-08-26

### Added

- Using the [Nx](https://hexdocs.pm/nx) library to compute BDM for large 2D matrices (images) more efficiently



## [0.1.1] - 2025-08-21

### Fixed

- Fixed README.md 'Usage' section

- Fixed module documentation



## [0.1.0] - 2025-08-12

### Added

- Initial release
