v2.0.0

Cleora is now available as a Python package pycleora. Key improvements compared to the previous version:

• performance optimizations: ~10x faster embedding times
• performance optimizations: significantly reduced memory usage
• latest research: improved embedding quality
• new feature: can create graphs from a Python iterator in addition to tsv files
• new feature: seamless integration with NumPy
• new feature: item attributes support via custom embeddings initialization
• new feature: adjustable vector projection / normalization after each propagation step

Breaking changes:

• transient modifier not supported any more - creating complex::reflexive columns for hypergraph embeddings, grouped by the transient entity gives better results.

v1.2.3

Changed

• Bump libs (#60).

Fixed

• Check for malformed lines in input (#59).

v1.2.2

Changed

• Allow cleora to accept multiple input files as positional args. Named argument 'input' is getting deprecated (#55).

v1.2.1

Changed

• Optimize "--output-format numpy" mode, so it doesn't require additional memory when writing output file (#50).
• Bump libs (#52).

v1.2.0

Added

• Use default hasher for vector init. (#47).

v1.1.1

Added

• Init embedding with seed during training (#27).

Cleora v1.1.0

Changed

• Bumped env_logger to 0.8.2, smallvec to 1.5.1, removed fnv hasher (#11).

Added

• Tests (snapshots) for in-memory and memory-mapped files calculations of embeddings (#12).
• Support for NumPy output format (available via --output-format program argument) (#15).
• Jupyter notebooks with experiments (#16).

Improved

• Used vector for hash_to_id mappings, non-allocating cartesian product, ryu crate for faster write (#13).
• Sparse Matrix refactor (cleanup, simplification, using iter, speedup). Use Cargo.toml data for clap crate (#17).
• Unify and simplify embeddings calculation for in-memory and mmap matrices (#18).

Cleora v1.0.1

Fixed

• Skip reading invalid UTF-8 line (#8).
• Fix clippy warnings (#7).

Added

• JSON support (#3).
• Snapshot testing (#5).
