### LocallyConnected1D

```
keras.layers.local.LocallyConnected1D(nb_filter, filter_length, init='uniform', activation='linear', weights=None, border_mode='valid', subsample_length=1, W_regularizer=None, b_regularizer=None, activity_regularizer=None, W_constraint=None, b_constraint=None, bias=True, input_dim=None, input_length=None)
```

The `LocallyConnected1D`

layer works similarly to
the `Convolution1D`

layer, except that weights are unshared,
that is, a different set of filters is applied at each different patch
of the input.
When using this layer as the first layer in a model,
either provide the keyword argument `input_dim`

(int, e.g. 128 for sequences of 128-dimensional vectors), or `input_shape`

(tuple of integers, e.g. `input_shape=(10, 128)`

for sequences of 10 vectors of 128-dimensional vectors).
Also, note that this layer can only be used with
a fully-specified input shape (`None`

dimensions not allowed).

**Example**

```
# apply a unshared weight convolution 1d of length 3 to a sequence with
# 10 timesteps, with 64 output filters
model = Sequential()
model.add(LocallyConnected1D(64, 3, input_shape=(10, 32)))
# now model.output_shape == (None, 8, 64)
# add a new conv1d on top
model.add(LocallyConnected1D(32, 3))
# now model.output_shape == (None, 6, 32)
```

**Arguments**

**nb_filter**: Dimensionality of the output.**filter_length**: The extension (spatial or temporal) of each filter.**init**: name of initialization function for the weights of the layer (see initializations), or alternatively, Theano function to use for weights initialization. This parameter is only relevant if you don't pass a`weights`

argument.**activation**: name of activation function to use (see activations), or alternatively, elementwise Theano function. If you don't specify anything, no activation is applied (ie. "linear" activation: a(x) = x).**weights**: list of numpy arrays to set as initial weights.**border_mode**: Only support 'valid'. Please make good use of ZeroPadding1D to achieve same output length.**subsample_length**: factor by which to subsample output.**W_regularizer**: instance of WeightRegularizer (eg. L1 or L2 regularization), applied to the main weights matrix.**b_regularizer**: instance of WeightRegularizer, applied to the bias.**activity_regularizer**: instance of ActivityRegularizer, applied to the network output.**W_constraint**: instance of the constraints module (eg. maxnorm, nonneg), applied to the main weights matrix.**b_constraint**: instance of the constraints module, applied to the bias.**bias**: whether to include a bias (i.e. make the layer affine rather than linear).**input_dim**: Number of channels/dimensions in the input. Either this argument or the keyword argument`input_shape`

must be provided when using this layer as the first layer in a model.**input_length**: Length of input sequences, when it is constant. This argument is required if you are going to connect`Flatten`

then`Dense`

layers upstream (without it, the shape of the dense outputs cannot be computed).

**Input shape**

3D tensor with shape: `(samples, steps, input_dim)`

.

**Output shape**

3D tensor with shape: `(samples, new_steps, nb_filter)`

.
`steps`

value might have changed due to padding.

### LocallyConnected2D

```
keras.layers.local.LocallyConnected2D(nb_filter, nb_row, nb_col, init='glorot_uniform', activation='linear', weights=None, border_mode='valid', subsample=(1, 1), dim_ordering='default', W_regularizer=None, b_regularizer=None, activity_regularizer=None, W_constraint=None, b_constraint=None, bias=True)
```

The `LocallyConnected2D`

layer works similarly
to the `Convolution2D`

layer, except that weights are unshared,
that is, a different set of filters is applied at each
different patch of the input.
When using this layer as the
first layer in a model, provide the keyword argument `input_shape`

(tuple
of integers, does not include the sample axis), e.g.
`input_shape=(3, 128, 128)`

for 128x128 RGB pictures.
Also, note that this layer can only be used with
a fully-specified input shape (`None`

dimensions not allowed).

**Examples**

```
# apply a 3x3 unshared weights convolution with 64 output filters on a 32x32 image:
model = Sequential()
model.add(LocallyConnected2D(64, 3, 3, input_shape=(3, 32, 32)))
# now model.output_shape == (None, 64, 30, 30)
# notice that this layer will consume (30*30)*(3*3*3*64) + (30*30)*64 parameters
# add a 3x3 unshared weights convolution on top, with 32 output filters:
model.add(LocallyConnected2D(32, 3, 3))
# now model.output_shape == (None, 32, 28, 28)
```

**Arguments**

**nb_filter**: Number of convolution filters to use.**nb_row**: Number of rows in the convolution kernel.**nb_col**: Number of columns in the convolution kernel.**init**: name of initialization function for the weights of the layer (see initializations), or alternatively, Theano function to use for weights initialization. This parameter is only relevant if you don't pass a`weights`

argument.**activation**: name of activation function to use (see activations), or alternatively, elementwise Theano function. If you don't specify anything, no activation is applied (ie. "linear" activation: a(x) = x).**weights**: list of numpy arrays to set as initial weights.**border_mode**: Only support 'valid'. Please make good use of ZeroPadding2D to achieve same output shape.**subsample**: tuple of length 2. Factor by which to subsample output. Also called strides elsewhere.**W_regularizer**: instance of WeightRegularizer (eg. L1 or L2 regularization), applied to the main weights matrix.**b_regularizer**: instance of WeightRegularizer, applied to the bias.**activity_regularizer**: instance of ActivityRegularizer, applied to the network output.**W_constraint**: instance of the constraints module (eg. maxnorm, nonneg), applied to the main weights matrix.**b_constraint**: instance of the constraints module, applied to the bias.**dim_ordering**: 'th' or 'tf'. In 'th' mode, the channels dimension (the depth) is at index 1, in 'tf' mode is it at index 3.**bias**: whether to include a bias (i.e. make the layer affine rather than linear).

**Input shape**

4D tensor with shape:
`(samples, channels, rows, cols)`

if dim_ordering='th'
or 4D tensor with shape:
`(samples, rows, cols, channels)`

if dim_ordering='tf'.

**Output shape**

4D tensor with shape:
`(samples, nb_filter, new_rows, new_cols)`

if dim_ordering='th'
or 4D tensor with shape:
`(samples, new_rows, new_cols, nb_filter)`

if dim_ordering='tf'.
`rows`

and `cols`

values might have changed due to padding.
