# PyRCN
**A Python 3 framework for Reservoir Computing with a [scikit-learn](https://scikit-learn.org/stable/)-compatible API.**

[![PyPI version](https://badge.fury.io/py/PyRCN.svg)](https://badge.fury.io/py/PyRCN)
[![Documentation Status](https://readthedocs.org/projects/pyrcn/badge/?version=latest)](https://pyrcn.readthedocs.io/en/latest/?badge=latest)

PyRCN ("Python Reservoir Computing Networks") is a light-weight and transparent Python 3 framework for Reservoir Computing and is based on widely used scientific Python packages, such as numpy or scipy. 
The API is fully scikit-learn-compatible, so that users of scikit-learn do not need to refactor their code in order to use the estimators implemented by this framework. 
Scikit-learn's built-in parameter optimization methods and example datasets can also be used in the usual way.

PyRCN is used by the [Chair of Speech Technology and Cognitive Systems, Institute for Acoustics and Speech Communications, Technische Universität Dresden, Dresden, Germany](https://tu-dresden.de/ing/elektrotechnik/ias/stks?set_language=en) 
and [IDLab (Internet and Data Lab), Ghent University, Ghent, Belgium](https://www.ugent.be/ea/idlab/en). 

Currently, it implements Echo State Networks (ESNs) by Herbert Jaeger and Extreme Learning Machines (ELMs) by Guang-Bin Huang in different flavors, e.g. Classifier and Regressor. It is actively developed to be extended into several directions:

- Interaction with [sktime](http://sktime.org/)
- Interaction with [hmmlearn](https://hmmlearn.readthedocs.io/en/stable/)
- More towards future work: Related architectures, such as Liquid State Machines (LSMs) and Perturbative Neural Networks (PNNs)

PyRCN has successfully been used for several tasks:

- Music Information Retrieval (MIR)
    - Multipitch tracking
    - Onset detection
    - $f_{0}$ analysis of spoken language
    - GCI detection in raw audio signals
- Time Series Prediction
    - Mackey-Glass benchmark test
    - Stock price prediction
- Ongoing research tasks:
    - Beat tracking in music signals
    - Pattern recognition in sensor data
    - Phoneme recognition
    - Unsupervised pre-training of RCNs and optimization of ESNs

Please see the [References section](#references) for more information. For code examples, see [Getting started](#getting-started).

## Getting Started

PyRCN includes currently variants of Echo State Networks (ESNs) and Extreme Learning Machines (ELMs): Regressors and Classifiers.

Basic example for the ESNClassifier:

```python
from sklearn.model_selection import train_test_split
from pyrcn.datasets import load_digits
from pyrcn.echo_state_network import ESNClassifier

X, y = load_digits(return_X_y=True, as_sequence=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

clf = ESNClassifier()
clf.fit(X=X_train, y=y_train)

y_pred_classes = clf.predict(X=X_test)  # output is the class for each input example
y_pred_proba = clf.predict_proba(X=X_test)  #  output are the class probabilities for each input example
```

Basic example for the ESNRegressor:

```python
from pyrcn.datasets import mackey_glass
from pyrcn.echo_state_network import ESNRegressor

X, y = mackey_glass(n_timesteps=20000)

reg = ESNRegressor()
reg.fit(X=X[:8000], y=y[:8000])

y_pred = reg.predict(X[8000:])  # output is the prediction for each input example
```

An extensive introduction to getting started with PyRCN is included in the [examples](https://github.com/TUD-STKS/PyRCN/blob/main/examples) directory. 
The notebook [digits](https://github.com/TUD-STKS/PyRCN/blob/main/examples/digits.ipynb) or its corresponding [Python script](https://github.com/TUD-STKS/PyRCN/blob/main/examples/digits.py) show how to set up an ESN for a small hand-written digit recognition experiment.

# PyRCN
**A Python 3 framework for Reservoir Computing with a [scikit-learn](https://scikit-learn.org/stable/)-compatible API.**

[![PyPI version](https://badge.fury.io/py/PyRCN.svg)](https://badge.fury.io/py/PyRCN)
[![Documentation Status](https://readthedocs.org/projects/pyrcn/badge/?version=latest)](https://pyrcn.readthedocs.io/en/latest/?badge=latest)

PyRCN ("Python Reservoir Computing Networks") is a light-weight and transparent Python 3 framework for Reservoir Computing and is based on widely used scientific Python packages, such as numpy or scipy. 
The API is fully scikit-learn-compatible, so that users of scikit-learn do not need to refactor their code in order to use the estimators implemented by this framework. 
Scikit-learn's built-in parameter optimization methods and example datasets can also be used in the usual way.

PyRCN is used by the [Chair of Speech Technology and Cognitive Systems, Institute for Acoustics and Speech Communications, Technische Universität Dresden, Dresden, Germany](https://tu-dresden.de/ing/elektrotechnik/ias/stks?set_language=en) 
and [IDLab (Internet and Data Lab), Ghent University, Ghent, Belgium](https://www.ugent.be/ea/idlab/en). 

Currently, it implements Echo State Networks (ESNs) by Herbert Jaeger and Extreme Learning Machines (ELMs) by Guang-Bin Huang in different flavors, e.g. Classifier and Regressor. It is actively developed to be extended into several directions:

- Interaction with [sktime](http://sktime.org/)
- Interaction with [hmmlearn](https://hmmlearn.readthedocs.io/en/stable/)
- More towards future work: Related architectures, such as Liquid State Machines (LSMs) and Perturbative Neural Networks (PNNs)

PyRCN has successfully been used for several tasks:

- Music Information Retrieval (MIR)
    - Multipitch tracking
    - Onset detection
    - $f_{0}$ analysis of spoken language
    - GCI detection in raw audio signals
- Time Series Prediction
    - Mackey-Glass benchmark test
    - Stock price prediction
- Ongoing research tasks:
    - Beat tracking in music signals
    - Pattern recognition in sensor data
    - Phoneme recognition
    - Unsupervised pre-training of RCNs and optimization of ESNs

# PyRCN
**A Python 3 framework for Reservoir Computing with a [scikit-learn](https://scikit-learn.org/stable/)-compatible API.**

[![PyPI version](https://badge.fury.io/py/PyRCN.svg)](https://badge.fury.io/py/PyRCN)
[![Documentation Status](https://readthedocs.org/projects/pyrcn/badge/?version=latest)](https://pyrcn.readthedocs.io/en/latest/?badge=latest)

PyRCN ("Python Reservoir Computing Networks") is a light-weight and transparent Python 3 framework for Reservoir Computing and is based on widely used scientific Python packages, such as numpy or scipy. 
The API is fully scikit-learn-compatible, so that users of scikit-learn do not need to refactor their code in order to use the estimators implemented by this framework. 
Scikit-learn's built-in parameter optimization methods and example datasets can also be used in the usual way.

PyRCN is used by the [Chair of Speech Technology and Cognitive Systems, Institute for Acoustics and Speech Communications, Technische Universität Dresden, Dresden, Germany](https://tu-dresden.de/ing/elektrotechnik/ias/stks?set_language=en) 
and [IDLab (Internet and Data Lab), Ghent University, Ghent, Belgium](https://www.ugent.be/ea/idlab/en). 

Currently, it implements Echo State Networks (ESNs) by Herbert Jaeger and Extreme Learning Machines (ELMs) by Guang-Bin Huang in different flavors, e.g. Classifier and Regressor. It is actively developed to be extended into several directions:

- Interaction with [sktime](http://sktime.org/)
- Interaction with [hmmlearn](https://hmmlearn.readthedocs.io/en/stable/)
- More towards future work: Related architectures, such as Liquid State Machines (LSMs) and Perturbative Neural Networks (PNNs)

PyRCN has successfully been used for several tasks:

- Music Information Retrieval (MIR)
    - Multipitch tracking
    - Onset detection
    - $f_{0}$ analysis of spoken language
    - GCI detection in raw audio signals
- Time Series Prediction
    - Mackey-Glass benchmark test
    - Stock price prediction
- Ongoing research tasks:
    - Beat tracking in music signals
    - Pattern recognition in sensor data
    - Phoneme recognition
    - Unsupervised pre-training of RCNs and optimization of ESNs

Please see the [References section](#references) for more information. For code examples, see [Getting started](#getting-started).

## Installation

### Prerequisites

PyRCN is developed using Python 3.7 or newer. It depends on the following packages:

- [numpy>=1.18.1](https://numpy.org/)
- [scikit-learn>=1.0](https://scikit-learn.org/stable/)
- [joblib>=0.13.2](https://joblib.readthedocs.io)
- [pandas>=1.0.0](https://pandas.pydata.org/)
- [matplotlib](https://matplotlib.org/)
- [seaborn](https://seaborn.pydata.org/)

### Installation from PyPI

The easiest and recommended way to install ``PyRCN`` is to use ``pip`` from [PyPI](https://pypi.org) :

```
pip install pyrcn
```

### Installation from source

If you plan to contribute to ``PyRCN``, you can also install the package from source.

Clone the Git repository:

```
git clone https://github.com/TUD-STKS/PyRCN.git
```

Install the package using ``setup.py``:
```
python setup.py install --user
```

## Offcial documentation

See [the official PyRCN documentation](https://pyrcn.readthedocs.io/en/latest/?badge=latest)
to learn more about the main features of PyRCN, its API and the installation process.

## Package structure
The package is structured in the following way: 

- `doc`
    - This folder includes the package documentation.
- `examples`
    - This folder includes example code as Jupyter Notebooks and python scripts.
- `images`
    - This folder includes the logos used in ´README.md´.
- `pyrcn`
    - This folder includes the actual Python package.


## Getting Started

PyRCN includes currently variants of Echo State Networks (ESNs) and Extreme Learning Machines (ELMs): Regressors and Classifiers.

Basic example for the ESNClassifier:

```python
from sklearn.model_selection import train_test_split
from pyrcn.datasets import load_digits
from pyrcn.echo_state_network import ESNClassifier

X, y = load_digits(return_X_y=True, as_sequence=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

clf = ESNClassifier()
clf.fit(X=X_train, y=y_train)

y_pred_classes = clf.predict(X=X_test)  # output is the class for each input example
y_pred_proba = clf.predict_proba(X=X_test)  #  output are the class probabilities for each input example
```

Basic example for the ESNRegressor:

```python
from pyrcn.datasets import mackey_glass
from pyrcn.echo_state_network import ESNRegressor

X, y = mackey_glass(n_timesteps=20000)

reg = ESNRegressor()
reg.fit(X=X[:8000], y=y[:8000])

y_pred = reg.predict(X[8000:])  # output is the prediction for each input example
```

An extensive introduction to getting started with PyRCN is included in the [examples](https://github.com/TUD-STKS/PyRCN/blob/main/examples) directory. 
The notebook [digits](https://github.com/TUD-STKS/PyRCN/blob/main/examples/digits.ipynb) or its corresponding [Python script](https://github.com/TUD-STKS/PyRCN/blob/main/examples/digits.py) show how to set up an ESN for a small hand-written digit recognition experiment. 
Launch the digits notebook on Binder: 

[![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/TUD-STKS/PyRCN/main?filepath=examples%2Fdigits.ipynb)

The notebook [PyRCN_Intro](https://github.com/TUD-STKS/PyRCN/blob/main/examples/PyRCN_Intro.ipynb) or its corresponding [Python script](https://github.com/TUD-STKS/PyRCN/blob/main/examples/PyRCN_Intro.py) show how to construct different RCNs with building blocks. 

[![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/TUD-STKS/PyRCN/main?filepath=examples%2FPyRCN_Intro.ipynb)

The notebook [Impulse responses](https://github.com/TUD-STKS/PyRCN/blob/main/examples/esn_impulse_responses.ipynb) is an interactive tool to demonstrate the impact of different hyper-parameters on the impulse responses of an ESN. 

[![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/TUD-STKS/PyRCN/main?filepath=examples%2Fesn_impulse_responses.ipynb)

Fore more advanced examples, please have a look at our [Automatic Music Transcription Repository](https://github.com/TUD-STKS/Automatic-Music-Transcription), in which we provide an entire feature extraction, training and test pipeline for multipitch tracking and for note onset detection using PyRCN. This is currently transferred to this repository.
