the plot in figure - shows that we have closing price information available since up until recently kindly note that the same information is also available through quandl (which we used in the previous section to get gold price informationyou may use the same to get this data as well recurrent neural networkslstm artificial neural networks are being employed to solve number of use cases in variety of domains recurrent neural networks are class of neural networks with capabilities of modeling sequential data lstms or long short term memory is an rnn architecture that' useful for modeling arbitrary intervals of information rnnsparticularly lstms were discussed in while practical use case was explored in for analyzing textual data from movie reviews for sentiment analysis figure - basic structure of rnn and lstm units (sourcechristopher olah' blogcolah github ioas quick refresherfigure - points toward the general architecture of an rnn along with the internals of typical lstm unit lstm comprises of three major gates--the inputoutputand forget gates these gates work in tandem to learn and store long and short term sequence related information for more detailsrefer to advanced supervised deep learning models
