Please don't take this as financial advice or use it to make any trades of your own. Introduction to LSTMs: Making Stock Movement Predictions Far into the Future. We'll explain more as we go through this tutorial. There are currently some limitations with using the vanilla LSTMs described above, specifically in the use of a financial time series, the series itself has non-stationary properties which is very hard to model (although advancements have been made in using Bayesian Deep Neural Network methods for tackling non-stationarity of time series). LSTM is designed to forecast, predict and classify time series data even long time lags between vital events happened before. LSTM expects the data to be in a supervised learning mode. Let’s take a human life, and imagine that we are receiving various streams of data about that life in a time series. Increase the accuracy by trying new machine learning methods.
