How to use CNN for making predictions on non-image data?
You can use CNN on any data, but it''s recommended to use CNN only on data that have spatial features (It might still work on data that doesn''t have spatial features, see DuttaA''s comment below). For
Extract features with CNN and pass as sequence to RNN
But if you have separate CNN to extract features, you can extract features for last 5 frames and then pass these features to RNN. And then you do CNN part for 6th frame and you pass
What is the difference between CNN-LSTM and RNN?
Why would "CNN-LSTM" be another name for RNN, when it doesn''t even have RNN in it? Can you clarify this? What is your knowledge of RNNs and CNNs? Do you know what an LSTM is?
