How to Model Volatility with ARCH and GARCH for Time Series Forecasting in Python

A change in the variance or volatility over time can cause problems when modeling time series with classical methods like ARIMA. The ARCH or Autoregressive Conditional Heteroskedasticity method provides a way to model a change in variance in a time series that is time dependent, such as increasing or decreasing volatility. An extension of this approach […]

4 Common Machine Learning Data Transforms for Time Series Forecasting

4 Common Machine Learning Data Transforms for Time Series Forecasting

Time series data often requires some preparation prior to being modeled with machine learning algorithms. For example, differencing operations can be used to remove trend and seasonal structure from the sequence in order to simplify the prediction problem. Some algorithms, such as neural networks, prefer data to be standardized and/or normalized prior to modeling. Any […]

The Promise of Recurrent Neural Networks for Time Series Forecasting

The Promise of Recurrent Neural Networks for Time Series Forecasting

Recurrent neural networks are a type of neural network that add the explicit handling of order in input observations. This capability suggests that the promise of recurrent neural networks is to learn the temporal context of input sequences in order to make better predictions. That is, that the suite of lagged observations required to make […]
