Timeseries Classification: KNN & DTW
K-Nearest Neighbors algorithm (k-NN) is a non parametric method used for classification.
Algorithm:
1. Choose a value for k
2. Find the distance between unlabeled point and training points.
3. Find the k-nearest points to unlabeled points
4. Classify unlabeled point by a majority vote of its neighbors
