title: Multidimensional Input to Keras LSTM - (for Classification)
body: <p>I am trying to classify a bunch of spectrograms into C classes using keras' LSTM (with a Dense Layer at the end). To clarify, each spectrogram belongs to a single class from those C classes. Each spectrogram is basically a matrix. It is constructed by taking (lets say, K) measurements at every second for about 1000 seconds. So the matrix has K rows and 1000 columns. </p>
  
  <p>Considering this, how may I specify the shape of this input for the LSTM layer ? </p>
  
  <p>Thank you!</p>
