Aeon Time Series Machine Learning
Overview
Aeon is a scikit-learn compatible Python toolkit for time series machine learning (aeon-toolkit.org). It provides algorithms across classification, regression, clustering, forecasting, anomaly detection, segmentation, similarity search, distances, transformations, benchmarking, and visualization — with a consistent estimator API.
Version note: Reviewed against aeon 1.6.0 (Python 3.13). Small synthetic checks cover classification, regression, clustering, forecasts, preprocessing, distances, search, segmentation, matrix profiles, metrics, and local dataset I/O. Remote archive and TensorFlow training snippets are illustrative; they were not executed during this review. Reference catalogs are selected methods, not exhaustive lists. See the .
Detecting anomalies or change points in temporal sequences
Clustering similar time series patterns
Forecasting future values
Finding repeated patterns (motifs) or unusual subsequences (discords)
Comparing time series with specialized distance metrics
Extracting features from temporal data
Installation
Requires Python 3.11-3.14. Pin the reviewed release for reproducibility:
uv pip install "aeon==1.6.0"
Install only the extras required by the chosen estimator. The broad optional set is available as:
uv pip install "aeon[all_extras]==1.6.0"
On zsh, quote the extras: uv pip install "aeon[all_extras]==1.6.0".
For the matrix-profile examples: uv pip install "aeon==1.6.0" stumpy. Range precision/recall/F-score depend on prts, whose current NumPy<2 requirement conflicts with aeon 1.6; use the runnable AUC metrics or a separately validated environment. Deep learning estimators use TensorFlow. Inspect an estimator's python_dependencies tag before installing optional packages.
Experimental modules
Upstream treats forecasting, anomaly_detection, segmentation, similarity_search, and visualisation as experimental — interfaces may change between minor releases. Prefer stable modules (classification, regression, clustering, distances, transformations) for production pipelines unless you need these tasks.
Core Capabilities
1. Time Series Classification
Categorize time series into predefined classes. See references/classification.md for selected methods.
Partition time series into regions with change points. See references/segmentation.md.
Quick Start:
from aeon.segmentation import ClaSPSegmenter
segmenter = ClaSPSegmenter()
change_points = segmenter.fit_predict(y)
7. Similarity Search
Find similar patterns within or across time series. See references/similarity_search.md.
Quick Start:
from aeon.similarity_search.subsequence import MASS
# X_train: (n_cases, n_channels, n_timepoints); query: (n_channels, 20)
searcher = MASS(length=20, normalize=True).fit(X_train)
query = X_train[0, :, :20]
indices, distances = searcher.predict(query, k=3, X_index=(0, 0))
# indices rows are (case_index, window_start); self-match is excluded
Feature Extraction and Transformations
Transform time series for feature engineering. See references/transformations.md.
ROCKET Features:
from aeon.transformations.collection.convolution_based import Rocket
rocket = Rocket()
X_features = rocket.fit_transform(X_train)
# Use features with any sklearn classifier
from sklearn.ensemble import RandomForestClassifier
clf = RandomForestClassifier()
clf.fit(X_features, y_train)
Statistical Features:
from aeon.transformations.collection.feature_based import Catch22
catch22 = Catch22()
X_features = catch22.fit_transform(X_train)
from aeon.benchmarking.results_loaders import get_estimator_results
# Compare with published results
published = get_estimator_results("ROCKET", ["GunPoint"])
Common Workflows
Classification Pipeline
from aeon.transformations.collection import Normalizer
from aeon.classification.convolution_based import RocketClassifier
from sklearn.pipeline import Pipeline
pipeline = Pipeline([
('normalize', Normalizer()),
('classify', RocketClassifier())
])
pipeline.fit(X_train, y_train)
accuracy = pipeline.score(X_test, y_test)
Feature Extraction + Traditional ML
from aeon.transformations.collection.convolution_based import Rocket
from sklearn.ensemble import GradientBoostingClassifier
# Extract features
rocket = Rocket()
X_train_features = rocket.fit_transform(X_train)
X_test_features = rocket.transform(X_test)
# Train traditional ML
clf = GradientBoostingClassifier()
clf.fit(X_train_features, y_train)
predictions = clf.predict(X_test_features)
from aeon.transformations.collection import SimpleImputer
imputer = SimpleImputer(strategy='mean')
X_train = imputer.fit_transform(X_train)
Check Data Format: Collections use (n_cases, n_channels, n_timepoints); single series usually use (n_channels, n_timepoints) with axis=1. TimeEval loaders return timepoints by channels: use axis=0 where supported. Check capability tags for missing values, multivariate and unequal-length support (see data format)
Model Selection
Start Simple: Begin with ROCKET variants before deep learning
Use Validation: Tune within training data. Split by subject/group for repeated measurements and chronologically for forecasting or overlapping windows; random splits can leak information
Compare Baselines: Test against simple methods (1-NN Euclidean, Naive)
Consider Resources: ROCKET for speed, deep learning if GPU available
