Elephas implements a class of data-parallel algorithms on top of Keras, using Spark's RDDs and data frames. Keras Models are initialized on the driver, then serialized and shipped to workers, alongside with data and broadcasted model parameters. Note that we use the array_reshape() function rather than the dim<-() function to reshape the array. This is so that the data is re-interpreted using row-major semantics (as opposed to R’s default column-major semantics), which is in turn compatible with the way that the numerical libraries called by Keras interpret array dimensions. keras. tensorflowのラッパーであるkerasを用いてセマンティックセグメンテーションをおこなう。 学習環境 While the examples in the aforementioned tutorial do well to showcase the versatility of Keras on a wide range of autoencoder model architectures, its implementation of the variational autoencoder doesn't properly take advantage of Keras' modular design, making it difficult to generalize and extend in important ways.
