How to Model Residual Errors to Correct Time Series Forecasts with Python http://machinelearningmastery.com/model-residual-errors-correct-time-series-forecasts-python/
The residual errors from forecasts on a time series provide another source of information that we can model. Residual errors themselves form a time series that can have temporal structure. A simple autoregression model of this structure can be used to predict the forecast error, which in turn can be used to correct forecasts. This …

How to Grid Search ARIMA Model Hyperparameters with Python http://machinelearningmastery.com/grid-search-arima-hyperparameters-with-python/
The ARIMA model for time series analysis and forecasting can be tricky to configure. There are 3 parameters that require estimation by iterative trial and error from reviewing diagnostic plots and using 40-year-old heuristic rules. We can automate the process of evaluating a large number of hyperparameters for the ARIMA model by using a grid …

How to Check if Time Series Data is Stationary with Python http://machinelearningmastery.com/time-series-data-stationary-python/
Time series is different from more traditional classification and regression predictive modeling problems. The temporal structure adds an order to the observations. This imposed order means that important assumptions about the consistency of those observations needs to be handled specifically. For example, when modeling, there are assumptions that the summary statistics of observations are consistent. …

Helping Programmers be Awesome at Machine Learning
Introduction
The field of Machine Learning is fascinating and applied Machine Learning is thrilling. I believe Machine Learning is an open opportunity for programmers. I believe this because I think programmers are uniquely skilled to make some of the biggest contributions to the field. Namely taking it out of books, papers and competitions and making use of it in software. And software is eating the world.
