Keras Convolution 1D Layer

This layer creates a convolution kernel that is convolved with the layer input over a single dimension. Corresponds to the Keras Convolution 1D Layer.

Options

Name prefix

The name prefix of the layer. The prefix is complemented by an index suffix to obtain a unique layer name. If this option is unchecked, the name prefix is derived from the layer type.

Filters

The dimensionality of the output space (i.e. the number of output filters in the convolution).

Kernel size

The length of the 1D convolution window.

Strides

The stride length of the convolution. Specifying any stride value != 1 is incompatible with specifying any dilation_rate value != 1.

Padding

Different padding modes to apply to the spatial dimensions (excluding the batch and channel dimensions) of the inputs before the pooling operation. The padding will be done with zeroes. A detailed explanation of the different modes can be found here .

• Valid: No padding
• Same: Padding such that the spatial output dimension do not change.
• Causal: Causal (dilated) convolutions, e.g. output[t] does not depend on input[t + 1] . A zero padding is used such that the output has the same length as the original input. Useful when modeling temporal data where the model should not violate the temporal order. See WaveNet: A Generative Model for Raw Audio, section 2.1

Dilation rate

Specifying the dilation rate to use for dilated convolution. Currently, specifying any dilation_rate value != 1 is incompatible with specifying any stride value != 1.

Activation function

The activation function to use.

Use bias?

If checked, a bias vector will be used.

Kernel initializer

Initializer for the kernel weights matrix.

Bias initializer

Initializer for the bias vector.

Kernel regularizer

Regularizer function applied to the kernel weights matrix.

Bias regularizer

Regularizer function applied to the bias vector.

Activation regularizer

Regularizer function applied to the output of the layer (its "activation").

Kernel constraint

Constraint function applied to the kernel matrix.

Bias constraint

Constraint function applied to the bias vector.
