**Feature overview:**
- easy creation of [complex architectures](https://reservoirpy.readthedocs.io/en/latest/user_guide/model.html) with multiple reservoirs (e.g. *deep reservoirs*),
readouts
- [feedback loops](https://reservoirpy.readthedocs.io/en/latest/user_guide/advanced_demo.html#Feedback-connections)
- [offline and online training](https://reservoirpy.readthedocs.io/en/latest/user_guide/learning_rules.html)
- [parallel implementation](https://reservoirpy.readthedocs.io/en/latest/api/generated/reservoirpy.nodes.ESN.html)
- sparse matrix computation
- advanced learning rules (e.g. [*Intrinsic Plasticity*](https://reservoirpy.readthedocs.io/en/latest/api/generated/reservoirpy.nodes.IPReservoir.html), [*Local Plasticity*](https://reservoirpy.readthedocs.io/en/latest/api/generated/reservoirpy.nodes.LocalPlasticityReservoir.html) or [*NVAR* (Next-Generation RC)](https://reservoirpy.readthedocs.io/en/latest/api/generated/reservoirpy.nodes.NVAR.html))
- interfacing with [scikit-learn](https://reservoirpy.readthedocs.io/en/latest/api/generated/reservoirpy.nodes.ScikitLearnNode.html) models
- and many more!

Moreover, graphical tools are included to **easily explore hyperparameters**
with the help of the *hyperopt* library.

## Quick try ⚡

### Installation

```bash
pip install reservoirpy
```

For more complete installation (including hyperparameter search, ...), look at the [complete installation guide on ReadTheDocs](https://reservoirpy.readthedocs.io/en/latest/developer_guide/advanced_install.html).

### An example on chaotic timeseries prediction (Mackey-Glass)

For a general introduction to reservoir computing and ReservoirPy features, take
a look at the [tutorials](#tutorials)

```python
from reservoirpy.datasets import mackey_glass, to_forecasting
from reservoirpy.nodes import Reservoir, Ridge
from reservoirpy.observables import rmse, rsquare

### Step 1: Load the dataset

X = mackey_glass(n_timesteps=2000)  # (2000, 1)-shaped array
# create y by shifting X, and train/test split
x_train, x_test, y_train, y_test = to_forecasting(X, test_size=0.2)

### Step 2: Create an Echo State Network

# 100 neurons reservoir, spectral radius = 1.25, leak rate = 0.3
reservoir = Reservoir(units=100, sr=1.25, lr=0.3)
# feed-forward layer of neurons, trained with L2-regularization
readout = Ridge(ridge=1e-5)
# connect the two nodes
esn = reservoir >> readout

### Step 3: Fit, run and evaluate the ESN

esn.fit(x_train, y_train, warmup=100)
predictions = esn.run(x_test)

print(f"RMSE: {rmse(y_test, predictions)}; R^2 score: {rsquare(y_test, predictions)}")
# RMSE: 0.0020282; R^2 score: 0.99992
```
