Time Series and Sequence Data Networks

Deploy networks trained for time series classification, regression, and forecasting tasks to target FPGA and SoC boards

You can train and deploy networks to do time series classification, regression, and forecasting tasks by using long short-term memory (LSTM) networks. An LSTM is a type of recurrent neural network (RNN) that can learn long-term dependencies between time steps of sequence data. Learn about:
