Global max pooling operation for spatial data.

Global max pooling operation for spatial data.

layer_global_max_pooling_2d(object, data_format = NULL,
  batch_size = NULL, name = NULL, trainable = NULL, weights = NULL)

Arguments

object

Model or layer object

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, height, width, channels) while channels_first corresponds to inputs with shape (batch, channels, height, width). 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".

batch_size

Fixed batch size for layer

name

An optional name string for the layer. Should be unique in a model (do not reuse the same name twice). It will be autogenerated if it isn't provided.

trainable

Whether the layer weights will be updated during training.

weights

Initial weights for layer.

Input shape

  • If data_format='channels_last': 4D tensor with shape: (batch_size, rows, cols, channels)

  • If data_format='channels_first': 4D tensor with shape: (batch_size, channels, rows, cols)

Output shape

2D tensor with shape: (batch_size, channels)
