Sainath, Oriol Vinyals, Andrew Senior, Has¸im Sak Google, Inc. We had a couple in hand for testing on Monday December 11th, nice! I ran through many of the machine learning and simulation testing problems that I have done on Titan cards in the past. Naively ﬂattening the CNN feature map into a vector in order to pass it to an LSTM would obfuscate the structure of the target. The anomaly is ~10% slower than the initial best fitting 1D model and has a Vp/Vs ratio higher than the surrounding crust, suggesting the presence of increased temperature or partial melt. These papers are presented in 13 symposia, including one on selected areas in communication for emerging topics. In this work, we introduce the ConvLSTM-FCN model that combines FCN and ConvLSTM by converting a certain convolutional layer in the FCN model into a ConvLSTM layer, thus adding the ability to model temporal dependen-cies within the input video sequence.
