tinytopics 0.5.1

Documentation

• Add badges for CI tests and mkdocs workflows to README.md (#24).
• Add PyTorch management guide link for uv to README.md (735fcca).

Maintenance

• Use hatchling 1.26.3 in pyproject.toml to work around rye publish errors (c56387c).

tinytopics 0.5.0

Improvements

• Increased the speed of generate_synthetic_data() significantly by using direct mixture sampling, which leverages the properties of multinomial distributions (#21).

  This change makes simulating data at the scale of 100K x 100K more feasible. Although the approaches before and after are mathematically equivalent, the data generated with the same seed in previous versions and this version onward will be bitwise different.

tinytopics 0.4.1

Documentation

• Use pip and python3 in command line instructions consistently.

tinytopics 0.4.0

Breaking changes

• tinytopics now requires Python >= 3.10 to use PEP 604 style shorthand syntax for union and optional types (#14).

Typing

• Refactor type hints to use more base abstract classes, making them less limiting to specific implementations (#14).

Testing

• Add unit tests for all functions using pytest, with a GitHub Actions workflow to run tests under Linux and Windows (#18).

Improvements

• Update articles to simplify import syntax using import tinytopics as tt (#16).
• Close precise figure handles in plot functions instead of the current figure (#18).

Bug fixes

• Plot functions now correctly use string and list type color palette inputs when specified (do not call them as functions) (#18).

tinytopics 0.3.0

Improvements

• Refactor the code to use a more functional style and add type hints to improve code clarity (#9).

tinytopics 0.2.0

New features

• Add scale_color_tinytopics() to support the coloring need for arbitrary number of topics (#4).

Improvements

• Simplify hyperparameter tuning by adopting modern stochastic gradient methods. fit_model() now uses a combination of the AdamW optimizer (with weight decay) and the cosine annealing (with warm restarts) scheduler (#2).

Bug fixes

• Fix "Structure plot" y-axis range issue by adding a normalize_rows argument to plot_structure() for normalizing rows so that they all sum exactly to 1, and explicitly setting the y-axis limit to [0, 1]. (#1).

Documentation

• Add text data topic modeling example article (#7).

tinytopics 0.1.3

Improvements

• Reorder arguments in plotting functions to follow conventions.

tinytopics 0.1.2

Improvements

• Reduce the minimum version requirement for all dependencies in pyproject.toml.

Documentation

• Add more details on PyTorch installation in README.md.
• Improve text quality in articles.

tinytopics 0.1.1

Improvements

• Add CHANGELOG.md to record changes.
• Add essential metadata to pyproject.toml.

tinytopics 0.1.0

New features

• First version.
