Knn time series python
WebFeb 13, 2024 · The K-Nearest Neighbor Algorithm (or KNN) is a popular supervised machine learning algorithm that can solve both classification and regression problems. The algorithm is quite intuitive and uses distance measures to find k closest neighbours to a new, unlabelled data point to make a prediction. WebSep 15, 2024 · Creating a time series model in Python allows you to capture more of the complexity of the data and includes all of the data elements that might be important. It also makes it possible to make adjustments to different measurements, tuning the model to make it potentially more accurate.
