hypertools.reduce.autoencoders.DeepAutoencoder

class hypertools.reduce.autoencoders.DeepAutoencoder(n_components=2, hidden_dims=None, epochs=100, batch_size=64, lr=0.001, device='auto', random_state=None, verbose=False)[source]

A multi-layer autoencoder reducer with configurable depth.

Parameters:
n_componentsint

Latent (bottleneck) dimensionality (default: 2).

hidden_dimsNone, int, or sequence of int

Hidden layer widths, outermost (closest to the input) first. None (default) computes 2 geometrically-spaced widths between the number of input features and n_components; a sequence sets the exact depth and widths (e.g. [64, 32, 16]).

epochs, batch_size, lr, device, random_state, verbose

See Autoencoder.

Attributes:
net_torch.nn.Module or None

The fitted network.

Methods

fit(X[, y])

Fit the autoencoder on X (see fit_transform); returns self.

fit_transform(X[, y])

Standardize X, train a fresh network on it, and return the fitted latent codes.

get_metadata_routing()

Get metadata routing of this object.

get_params([deep])

Get parameters for this estimator.

inverse_transform(Z)

Decode latent codes Z back to (standardization-undone) feature space.

set_inverse_transform_request(*[, Z])

Configure whether metadata should be requested to be passed to the inverse_transform method.

set_params(**params)

Set the parameters of this estimator.

transform(X)

Apply the already-fitted network to (new) X, without refitting.
