Conclusion
•
Time series forecasting is an important area of machine
learning that is often neglected. It is important because
there are so many prediction problems that involve a time
component. These problems are neglected because it is
time component that makes time series problems more
difficult to handle.

END
Deep learning for time series forecasting involves training models to predict future values based on historical data patterns. This method is used in various applications, such as sales forecasting and disease prediction, to make informed decisions and plan ahead effectively.

Time Series Forecasting Using Deep Learning BY BREHIMA KONE
1-Forecasting the values of future time steps of sequence by train a sequence to sequence regression LSTM network, where the responses are the training sequences with values shifted by one-time step. Forecast Time Series data using a long short-term memory (LSTM) network 2-Forecasting the values of multiple time step 3-Applying the deep learning -based time series prediction on some applications, such as chickenpox prediction.

Why time series forecasting Example, the most common, basic example of a time series is seasonal sales revenues. Many companies are exploring time series forecasting as a way of making better business decisions. Time series forecasting is the use of statistical methods to predict future behavior based on historical data. Time series is looking at data overtime to forecast or predict what will happen in the next time period.
Time Series Data A time series is a sequence of data points through time. Thus, when dealing with time series data, order matters. -Data is measured sequentially and equally space in time. Time series data have two important properties: -Each time unit has at most one measurement.
Time Series Patterns Most time series data usually have at least one of these three kinds of patterns: Trend Seasonality Cycle
Trend Figure1 The general behavior of a time serie
Seasonality A season pattern is any kind of fluctuation(change ) in a time series that caused by calendar-related events. Seasonality always has fixed frequencies. A seasonal pattern always starts and end in the same period of a week, year,etc.

Conclusion Time series forecasting is an important area of machine learning that is often neglected. It is important because there are so many prediction problems that involve a time component. These problems are neglected because it is time component that makes time series problems more difficult to handle.
