Time Series Forecasting with LSTM
Time series forecasting is a crucial task in many industries, including finance, sales, weather prediction, and more. In this course, we will dive into the world of time series forecasting using Long Short-Term Memory (LSTM) networks, a type of recurrent neural network (RNN) specifically designed for sequential data.
What is Time Series Forecasting?
Time series forecasting involves predicting future values based on previously observed data points that are indexed in time order. It plays a significant role in decision-making processes, allowing businesses and organizations to anticipate trends, make informed strategies, and optimize resource allocation.
Why Use LSTM for Time Series Forecasting?
LSTM networks have gained popularity in time series forecasting due to their ability to capture long-term dependencies and remember information from earlier time steps. Unlike other traditional forecasting methods, LSTM models are capable of handling non-linear patterns, making them highly effective in forecasting tasks across a wide range of domains.
