quicknn 1.0.9

An implementation of Feedforward Neural Networks for quick applications.

QuickNN

The quicknn is a Tensorflow-based package that aims to simplify the application of the feedforward neural networks in classification and regression problems. The main features of the quicknn package are:

• internally management of the categorical variables with one-hot-encoding(OHE) method batch-wise, just you have to feed it with pandas object;
• internally management of the validation of the data while training;
• possibility to stop the training phase, change some parameters and then resume the training from where it had remained;
• allows easy visualization of the learning curves using Tensorboard;

Example

from quicknn import QuickNN
from sklearn.datasets import load_boston
from sklearn.model_selection import train_test_split

X, y = load_boston(return_X_y=True)
X_train, X_val, y_train, y_val = train_test_split(X, y, test_size=0.25)

qnn = QuickNN(list_neurons=[100, 200, 1])
qnn.fit(X_train, y_train, n_epochs=10) ## In IPython session you can stop-change-resume the training.
qnn.fit(X_train, y_train, n_epochs=20) ## Just increasing the n_epochs.
qnn.fit(X_train, y_train, n_epochs=30,
        learning_rate=0.01) ## You can change e.g., the learning_rate param while training
y_pred = qnn.predict(X_val)

Installing

The dependencies are showed in requirements.txt, which can be installed with the command:

$ pip install -r requirements.txt

Then the library can easily downloaded through pip:

$ pip install quicknn
