Nueramic MathML

Nueramic-mathml is a library for visualizing and logging the steps of optimization algorithms in machine learning. The project uses torch for calculations and plotly for visualization.

pip install nueramic-mathml

Quick tour

Optimization

You can minimize the functions and see a detailed description of each step. After minimizing, you have a history with complete logs. Also available multidimensional optimisation.

def f(x): return x ** 3 - x ** 2 - x  # Minimum at x = 1
bounds = (0, 3)
one_optimize.golden_section_search(f, bounds, epsilon=0.01, verbose=True)[0]

Models

You can use our models for classification and regression

from nueramic_mathml.ml import LogisticRegressionRBF
from sklearn.datasets import make_moons

x, y = make_moons(10_000, noise=.1, random_state=84)
x, y = torch.tensor(x), torch.tensor(y)
logistic_model_rbf = LogisticRegressionRBF(x[:1000]).fit(x, y, show_epoch=10)
