FeatureSetSelector does not work when not set as the first item in a template.

FeatureSetSelector only works when set as the first step of a template. When no template is used, or when it is set to be in the middle of a template,...

FeatureUnion + StackingEstimator causes input data to be duplicated for the rest of the model, increasing computational load and complexity.

TPOT uses FeatureUnion to combined the outputs of multiple operators. However, it is possible for tpot to put in two stacking estimators within a FeatureUnion block. This causes tpot to...

TPOTs internal cross validation is not shuffled. Rather, data is split in sequential chunks in the order that it was passed in. (e.g indexes 1-10 is chunk 1, 11-20 is...

Currently there is not an intuitive way to check if the tpot estimator has the predict_proba function and is inconsistent with other sklearn pipelines/methods. ## Context of the issue The...

## What does this PR do? _mate_operator has a wrapper that tries to check if all its returned values are valid pipelines. The last returned item is actually a dictionary...

## Context of the issue [provide more detailed introduction to the issue itself and why it is relevant] In the examples here: https://epistasislab.github.io/tpot/examples/ The code uses `tpot = TPOTClassifier(generations=5, population_size=50,...

Since the release of TPOT in 2016, we and others have experimented with several ideas and improvements to the algorithm. However, due to the structure of TPOT's codebase, it has...

Population class logging is inefficient and needs to be optimized.

The population class stores its logs in a pandas data frame. This has very slow appends, which get slower the more items are in the data frame. This becomes a...

Currently, the configuration files are designed as optuna-compatible functions, but this adds boilerplate (such as f"_{name}".) And maybe confusing and hard to understand. It would help with clarity if we...
