Google AI Proposes Temporal Fusion Transformer for Multi-Horizon Time Series Forecasting
Time series forecasting is a useful data science tool for helping people predict what will happen in the future based on historical, time-stamped information. Google researchers recently explained how they developed and used the company’s Temporal Fusion Transformer (TFT) to achieve more progress with these types... Read more
Show Me the Data: 8 Awesome Time Series Sources
Thanks to the Internet of Things, smart cities, e-health, autonomous machines, and other innovations, time series datasets are being produced in even more massive quantities. It can be used for econometrics, trend detection, pattern recognition, predictions, and is an essential ingredient in statistics, machine learning, and... Read more
Facebook’s Prophet Forecasting Crystal Ball
Facebook’s Prophet is one of the most-liked forecasting approaches nowadays. Its usage is very well described, the code itself cleanly documented, hence instead of giving examples of Facebook’s Prophet, we will look under the hood to understand where these Bayesian model novelties lie. The Model The... Read more
Machine Learning for Time Series Data
Most organizations generate time-series data. The generation of sales data and financial data are primary components of all organizations’ business. This data is a form of time series data. Time series data consists of any data that carries a temporal component with it. Time series data... Read more
A Practitioner’s Guide To Interrupted Time Series
In the world of causal inference, Randomized Controlled Trials, RCTs, are considered the gold standard as it rules out any covariate differences before the intervention. However, running an RCT isn’t an option for multiple reasons (e.g., too expensive, invalid assumptions, too long, not ethical, etc.). [Related... Read more
