Alexander Ulanov commented on SPARK-5575: ----------------------------------------- Hi Janani, There is already an implemenation of DBN (and RBM) by [~gq]. You can find it here: https://github.com/witgo/spark/tree/ann-interface-gemm-dbn > Artificial neural networks for MLlib deep learning > -------------------------------------------------- > > Key: SPARK-5575 > URL: https://issues.apache.org/jira/browse/SPARK-5575 > Project: Spark > Issue Type: Umbrella > Components: MLlib > Affects Versions: 1.2.0 > Reporter: Alexander Ulanov > > Goal: Implement various types of artificial neural networks > Motivation: deep learning trend > Requirements: > 1) Basic abstractions such as Neuron, Layer, Error, Regularization, Forward > and Backpropagation etc. should be implemented as traits or interfaces, so > they can be easily extended or reused > 2) Implement complex abstractions, such as feed forward and recurrent networks > 3) Implement multilayer perceptron (MLP), convolutional networks (LeNet), > autoencoder (sparse and denoising), stacked autoencoder, restricted > boltzmann machines (RBM), deep belief networks (DBN) etc. > 4) Implement or reuse supporting constucts, such as classifiers, normalizers, > poolers, etc. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
