## Arguments

Arguments | Description |
---|---|

object | What to compose the new `Layer` instance with. Typically a Sequential model or a Tensor (e.g., as returned by `layer_input()` ). The return value depends on `object` . If `object` is: - missing or `NULL` , the `Layer` instance is returned. - a `Sequential` model, the model with an additional layer is returned. - a Tensor, the output tensor from `layer_instance(object)` is returned. |

filters | Integer, the dimensionality of the output space (i.e. the number of output filters in the convolution). |

kernel_size | An integer or list of n integers, specifying the dimensions of the convolution window. |

strides | An integer or list of n integers, specifying the strides of the convolution. Specifying any stride value != 1 is incompatible with specifying any `dilation_rate` value != 1. |

padding | One of `"valid"` or `"same"` (case-insensitive). `"valid"` means no padding. `"same"` results in padding evenly to the left/right or up/down of the input such that output has the same height/width dimension as the input. |

data_format | A string, one of `channels_last` (default) or `channels_first` . The ordering of the dimensions in the inputs. `channels_last` corresponds to inputs with shape `(batch, time, ..., channels)` while `channels_first` corresponds to inputs with shape `(batch, time, channels, ...)` . It defaults to the `image_data_format` value found in your Keras config file at `~/.keras/keras.json` . If you never set it, then it will be “channels_last”. |

dilation_rate | An integer or list of n integers, specifying the dilation rate to use for dilated convolution. Currently, specifying any `dilation_rate` value != 1 is incompatible with specifying any `strides` value != 1. |

activation | Activation function to use. By default hyperbolic tangent activation function is applied (`tanh(x)` ). |

recurrent_activation | Activation function to use for the recurrent step. |

use_bias | Boolean, whether the layer uses a bias vector. |

kernel_initializer | Initializer for the `kernel` weights matrix, used for the linear transformation of the inputs. |

recurrent_initializer | Initializer for the `recurrent_kernel` weights matrix, used for the linear transformation of the recurrent state. |

bias_initializer | Initializer for the bias vector. |

unit_forget_bias | Boolean. If TRUE, add 1 to the bias of the forget gate at initialization. Use in combination with `bias_initializer="zeros"` . This is recommended in Jozefowicz et al., 2015 |

kernel_regularizer | Regularizer function applied to the `kernel` weights matrix. |

recurrent_regularizer | Regularizer function applied to the `recurrent_kernel` weights matrix. |

bias_regularizer | Regularizer function applied to the bias vector. |

activity_regularizer | Regularizer function applied to. |

kernel_constraint | Constraint function applied to the `kernel` weights matrix. |

recurrent_constraint | Constraint function applied to the `recurrent_kernel` weights matrix. |

bias_constraint | Constraint function applied to the bias vector. |

return_sequences | Boolean. Whether to return the last output in the output sequence, or the full sequence. (default FALSE) |

return_state | Boolean Whether to return the last state in addition to the output. (default FALSE) |

go_backwards | Boolean (default FALSE). If TRUE, process the input sequence backwards. |

stateful | Boolean (default FALSE). If TRUE, the last state for each sample at index i in a batch will be used as initial state for the sample of index i in the following batch. |

dropout | Float between 0 and 1. Fraction of the units to drop for the linear transformation of the inputs. |

recurrent_dropout | Float between 0 and 1. Fraction of the units to drop for the linear transformation of the recurrent state. |

… | standard layer arguments. |

## Details

Similar to an LSTM layer, but the input transformations and recurrent transformations are both convolutional.
