title: How do 'forget gates' know not to remove essential information from the Cell State in an LSTM?
body: <p>First off, I apologize if this isn't appropriate for stack overflow. This isn't really a code related question rather than a theory question. </p>
  
  <p>This isn't completely clear to me. Say you have a massive passage that you want your LSTM to learn off of, how is it making sure it doesnt remove details from the first paragraph?</p>
