Contextualized - v0.2.8 -- Documentation Overhaul, New Statistical Tests

Major Updates

Minor Updates

  • Fixed bug in easy correlation networks prediction when indivudal_preds=False
  • Increased overall test coverage to 87%, only leaving out visualization utilities.
  • Added tests for correctness to all analysis tools. Models must identify the significance of known heterogeneous and homogeneous effects to pass integration tests.

Contextualized - v0.2.7 -- Linear Encoders, API Reference, and Developer Resources

Major Updates - Contextualize all models with linear encoders for simplicity and interpretability (set encoder_type='linear') - Added stable versions to all requirements, upgrading to torch >=2.1.0 and lightning >=2.0.0, Python >=3.8 - Added API reference for contextualized.easy and contextualized.analysis and search to online documentation - Added the Benefits of Contextualized ML demo notebook to the website - Silenced most pytorch logging to make the important stuff stand out

Minor Updates - Fixed bug in easy Bayesian networks error computation - Resolved distributed training on GPUs for the dags TensorDataset - Depreciating dev branch, using pypi for stable versioning and main branch for active development - Added tests for correctness, where models must recover known known data generation mechanisms to pass (not just converging on random data) - All code is black formatted and began adding type hints and docstrings as standard practice. Docstrings use Google style now. - Added resources and scripts to standardize development workflows and requirements (dev_requirements.txt, make_docs.sh, format_style.sh)

Contextualized - v0.2.6 -- Consistency Tests, P-values

Contextualization adds new flexibility to model inference. In this update, we add tests to assess when contextualization captures meaningful heterogeneous effects, and determine when these effects should be ignored.

Use analysis.pvals to estimate the significance of effects captured by contextualized modeling - calc_homogeneous_context_effects_pvals tests if the direct effect of context on outcomes is significant - calc_homogeneous_predictor_effects_pvals tests if the effect of context-invariant models on outcomes is significant - calc_heterogeneous_predictor_effects_pvals tests it the effect of context-dependent models on outcomes is significant

Use analysis.bootstraps with select_good_bootstraps to select only training runs which converge for follow-up analysis.

Contextualized - v0.2.5 -- DAG losses, factor graphs, neighborhood selection, and sklearn-style graph baselines

  • Major NOTMAD upgrades: Infer Contextualized DAGs with NOTMAD using the NOTEARS, Poly, or DAGMA losses, and use factor graphs to infer high dimensional DAGs!
  • More Contextualized Networks: Use ContextualizedNeighborhoodSelection in the regression module to do contextualized neighborhood selection and infer graphs using lasso regression with minimal assumptions.
  • Network Baselines: Use contextualized.baselines to infer traditional correlation networks and Bayesian networks using a simple sklearn-style interface (fit, predict, measure_mses), and create "grouped" versions of these models using any grouping or discrete context (e.g. clustering, feature splits, age groups, cell types) with the GroupedNetworks class -- and follow up with ContextualizedCorrelationNetworks or ContextualizedBayesianNetworks in the easy module to see how much more accurate contextualized models can be!
  • Set metamodel_type='Naive' in the regression and dags lightning_modules to remove archetypes and estimate models directly from a neural network (not yet in the sklearn-style easy models).
  • Set fit_intercept=False in the regression lightning_modules to remove contextualized intercepts, and only infer models with context-varying coefficients (not yet in the sklearn-style easy models).
  • Various bugfixes, including a sign-flip in easy correlation measure_mses.
  • Disabled dynamic trainer output to improve readability of stdout
