It is always hard to find a proper model to forecast time series data. One of the reasons is that models that use time-series data often expose to serial correlation. In this article, we will compare k nearest neighbor (KNN) regression which is a supervised machine learning method, with a more classical and stochastic process, autoregressive integrated moving average (ARIMA).
We will use the monthly prices of refined gold futures(XAUTRY) for one gram…Continue

There are five types of traditional time series models most commonly used in epidemic time series forecasting, which includes
AR models express the current value of the time series linearly in…Continue

In a previous blog-post we have seen how we can use Signal Processing techniques for the classification of time-series and signals.
A very short summary of that post is: We can use the Fourier Transform to transform a signal from its time-domain to its frequency domain. The peaks in the frequency spectrum indicate the most…Continue

In this tutorial a short introduction to Time Series Modeling and Forecasting is presented. Time Series appears in many industries today that rely on predicting and balancing demand and Supply (e-commerce, retailer , ride-sharing, etc..)
Hence, a good understanding of the underlying model generating the data can significantly help in predicting future…Continue
