Get Started

Installation

If you haven’t already, check out the installation guide to get Bingo setup.

Running an Example

Let’s run a quick example to ensure that the installation works properly.

Creating Training Data

import numpy as np
X = np.linspace(-10, 10).reshape((-1, 1))
y = 3.0 * X ** 2 - 2.0 * X

Visualizing Training Data

import matplotlib.pyplot as plt
plt.scatter(X, y)
plt.xlabel("X_0")
plt.ylabel("y")
plt.title("Training Data")
plt.show()

Fitting a Model

from bingo.symbolic_regression.symbolic_regressor import SymbolicRegressor
regressor = SymbolicRegressor()
regressor.fit(X, y)
print("Found model:", regressor.get_best_individual())
pred_y = regressor.predict(X)

/home/runner/work/bingo/bingo/bingo/symbolic_regression/__init__.py:31: UserWarning: Could not load C++ modules No module named 'bingocpp.build'
  warnings.warn(f"Could not load C++ modules {import_err}")

Found model: (X_0)(X_0) - (X_0) - (X_0) + (X_0)(X_0) + (X_0)(X_0)

Visualizing the Model’s Predictions

plt.scatter(X, y)
plt.scatter(X, pred_y)
plt.xlabel("X_0")
plt.ylabel("y")
plt.legend(["actual", "predicted"])
plt.show()
