Comments

Pairwise transformers, kernels/distances on tabular data and panel data - base class, examples, extension templates
Related to #52 (oldest open issue!) and #1062.

This PR contains:

base classes for a new scitype: pairwise transformers, i.e., distance matrix makers and kernel matrix makers; there are two base classes for two different inputs, tabular (classical distances/kernels) and time series panels (e.g., time warping distances)

an example tabular distance ScipyDist that interfaces the scipy distances

an example panel distance AggrDist that uses any tabular distance to create an aggregate sample distance between time series, e.g., the mean Euclidean distance

extension templates for both scitypes

tests for the concrete scitypes added

This may be useful for future extension of the clustering module, or refactorings and extensions of the TSC module, @chrisholder, @TonyBagnall.

Also pinging @jasonlines since this is a proposal how the existing distances (due to @jasonlines) could be refactored.

[ENH] Save/Load Functionality for both Classical and DL Estimators
Reference Issues/PRs

Fixes #3022

What does this implement/fix? Explain your changes.

The Save/Load function for classical estimators is from #3336 and has been expanded for DL models along the same design. Keras is known to be problematic for certain kinds of (de)serialization, so this uses model.save() from keras along with pickle.dump(). The estimators are saved as .zip files.

Components of this directory include:

Metadata

Object

Keras History

Keras Model subdirectory

The first two components are the same as previously mentioned PR, stored differently to avoid this problem.

All the attributes are saved and restored (optimizers/history etc.) appropriately.

Does your contribution introduce a new dependency? If yes, which one?

No

What should a reviewer concentrate their feedback on?

One thing in __getstate__() and __setstate__() might be a source of contention, I've explained why it was necessary and I believe it is the simplest solution.

Any other comments?

Forecasting support for multivariate y and multiple input/output types - working prototype
This is a merge/review ready sketch for how multivariate y could be supported for multivariate forecasters, alongside the possibility to pass np.array and pd.Series. This is based on the design in STEP no.5, adapted to the new forecasting base class.

The key ingredient are:

converters parameterized by from, to, and as - in the convertIOmodule. Besides the obvious conversion functionality, the converters can be given access to a dictionary via reference in the store argument, where information for inverting lossy conversions (like from pd.DataFrame to np.array) can be stored

a new tag y_type which encodes the type of y that the private _fit, _predict, and _update assume internally - for now, it's just one type and not a list of compatible types

some logic in the public "plumbing" area of fit, predict, update, which converts inputs to the public layer to the desired input of the logic layer and back

This is for discussion, and I expect major change before we merge.

It might be especially interesting to discuss the following interaction with typing: the third argument of the converter, the "as" argument, is a scitype, and designed to have the same name as the respective typing composite type. Also see discussion in #965, #973 and #974.

Thinking of the logical continuation of this:

extend this to the other arguments, e.g., X

the individual argument checks like check_X etc should be replaced by checks of the kind check(what, as : scitype), e.g., check(y, "Series") should replace the less generic check_y.

extend this to time series classification, to support 3D numpy arrays, awkward arrays, nested data frames

A "visionary" pathway may see this working with type annotations that are scitypes, not typing machine types, e.g.,

fit(X : Series, Y : Series) etc _fit(X: Series, Y : UnivariateSeries)

and checks/conversions being done automatically.

[ENH] refactored `KNeighborsTimeSeriesClassifier`
This PR is a refactor of the KNeighborsTimeSeriesClassifier.

It does three things:

removes the (in my opinion) awkward and hard-to-maintain double inheritance of KNeighborsTimeSeriesClassifier from sklearn's knn classifier. Instead adopts a wrapper pattern around the sklearn public interface, with much of the code simplified through passing distance matrices directly to sklearn.

extends the interface to allow passing of arbitrary distances that are callables. This supports the composable distance interface from #1858 out-of-the-box (with sklearn style parameter inspectable composition/pipelining), and can be used to plug in custom time series distances.

tests that rely on random seeds are updated with new expected output values

This PR also fixes two unreported bugs:

the algorithm parameter of KNeighborsTimeSeriesClassifier was not passed to the sklearn KNeighbors classifier, the value being passed was always the default "brute". https://github.com/alan-turing-institute/sktime/issues/2774

corrected docstring in pairwise_distance which was missing options

and makes one minor change:

replaces loops in tests for KNeighborsTimeSeriesClassifier by mark.parametrize

[ENH] MLflow custom flavor for `sktime` forecasting
Reference Issues/PRs

Resolves #1215

What does this implement/fix? Explain your changes.

This PR adds mlflow custom model flavor for sktime. The implementation closely follows the approach of mlflow built-in model flavors, see pmdarima as an example in mlflow repo (for more details see mlflow.pmdarima and tests.pmdarima.test_pmdarima_model_export). I also added a mlflow notebook under examples which could be added to the sphinx docs.

Does your contribution introduce a new dependency? If yes, which one?

New dependencies introduced: boto3, mlflow, moto

I tried to add all dependencies as soft dependencies but ran into a challenge for mlflow. We need to import pyfunc from mlflow at the module level to enable loading sktime model as pyfunc flavor. This will not work if we import pyfunc inside the functions.

Would it be acceptable to have mlflow as core dependency or do you have another suggestion?

What should a reviewer concentrate their feedback on?

how we want to handle the open dependency question

check the _SktimeModelWrapperclass which contains the sktime custom inference logic

predict method of _SktimeModelWrapper is only allowed to take a single DataFrame as an input (see mlflow documentation for more details) - thus we can pass exogenous regressor only as 2D or 3D numpy array. Based on my understanding this would cover all forecasters utilizing scitypes Series and Panel - can you confirm this?

whether you see the need to add more unit tests

should we add example notebook to sphinx docs? Is there anything in the code that needs to be modified for this inclusion?

Any other comments?

dev packages useful for development and testing

binder packages required for binder and running notebook examples

docs packages required to build the documentation

Add section to build time dependencies.

Refactor existing CI/CD pipelines to use the new build configuration.

Introduced a new CI/CD pipelines for running tests across win, mac, linux and py37, py38, py39 with github actions.

Removed the obsolete requirements files.

Include wheels build for macosx on arm64.

Removed

❌ Drop support for python3.6

❌ Drop appveyor and azure pipelines

High level diagram for the CI/CD workflows

Does your contribution introduce a new dependency? If yes, which one?

It does not introduce any new runtime/install dependencies but it could introduce an optional development depencency/build system such as poetry to simplify development/build/distribution.

What should a reviewer concentrate their feedback on?

This PR introduces changed to the CI/CD pipelines that would hopefully allow to drop appveyor and azure pipelines in favor of github actions which would simplify the current build and maintenance process.

Any other comments?

[ENH] Early classification base class

Implementation of a base class and converted tests for early classification https://github.com/alan-turing-institute/sktime/issues/1616. Refactors TEASER to use the new base class.

The new class is very similar to the classification base class, except predict/predict_proba returns 3 ndarrays instead of 1. The first is the already present predictions/probabilities, the second is a set of decisions on whether the returned predictions are safe to use, and the third is a set of state information for each case for use in later decisions and putting together eTSC statistics.

An optional state_info input for the predict/predict_proba is also required.

[BUG] Unable to use RandomShapeletTransform with classifiers in a pipeline, report "TypeError: X is not of a supported"

Describe the bug I want to train a model to classify some time series data. I think using shapelet-based time series processing is suitable for my data. So I combined RandomShapeletTransform with MLPClassifier to build a classify pipeline. However, when I tried to fit the pipeline, it reports an error. Could you please review it and give me some suggestions?

To Reproduce

from sktime.classification.deep_learning import MLPClassifier
from sktime.transformations.panel.shapelet_transform import RandomShapeletTransform    
from sktime.datasets import load_unit_test

X_train, y_train = load_unit_test(split="train", return_X_y=True)
estimator = MLPClassifier()
transformer = RandomShapeletTransform()
pipeline = transformer * estimator
pipeline.fit(X_train,y_train)

Here's the output:

Traceback (most recent call last):
  File "/runners/run_train.py", line 20, in <module>
    trainSettingAndRecords = test_pipeline()

[BUG] LSTM deep learning estimators failing CI on windows
Since recently, a failure of two deep learning estimators has been appearing on windows CI:

FAILED sktime/tests/test_all_estimators.py::TestAllEstimators::test_methods_have_no_side_effects[MLPClassifier-1-ClassifierFitPredictMultivariate-predict] FAILED sktime/tests/test_all_estimators.py::TestAllEstimators::test_methods_have_no_side_effects[LSTMFCNClassifier-0-ClassifierFitPredictMultivariate-predict]

Note that the failure appears to be only on python 3.9, but this is due to the matrix design which spreads estimators across version/OS combinations.

In theory, it could be a 3.9 specific failure, but I think that is less likely than windows specifity (although it may be worth to test that by turning the matrixdesign flag off in the CI).
