You can then proceed with implementing your deep learning model inside this function. Examples of using GridLSTM (and GridRNN in general) in tensorflow. However, I'm not exactly sure how to implement this. From this paper, Grid LSTM RNN's can be n-dimensional. v1. The LSTM model. Quite often, LSTM’s are stacked such that the hidden layer at a given timestep h t, is the input for the next layer of the LSTM. The GridRNN implementation in tensorflow is generic, in the sense that it supports multiple dimensions with various settings for input/output dimensions, priority dimensions and non-recurrent dimensions. In this post, we will demonstrate how to use Keras’ implementation of Long-Short Term Memory (LSTM) for Time Series Forecasting and MLFLow for tracking model runs.
