## Time Series Forecasting with STL

STL stands for “Seasonal and Trend decomposition using LOESS”. It is a versatile and robust method for decomposing time series. This method decomposes a time series into its three main components: Classical decomposition methods vs. STL Before carrying on with STL, let’s introduce traditional methods. Here you have an example Read more…

## Theoretical Introduction to Recurrent Neural Networks

Are you interested in mastering Time Series forecasting or natural language processing? Then you should learn about Recurrent Neural Networks. Recurrent Neural Networks or RNNs are a specialized form of neural network architecture engineered for sequence-based tasks. Unlike traditional feed-forward neural networks, which treat each input as independent, RNNs excel Read more…

## XGBoost to forecast univariate Time Series data with exogenous variables

In the last article, we learned how to train a Machine Learning model like Linear Regression or XGBoost to forecast Time Series data. We had to reframe the dataframe as a supervised learning problem. You can read about this process here. To explain the process we used Forex data, specifically Read more…
