Using the tslearn Python package, clustering a time series dataset with k-means and DTW simple: from tslearn.clustering import TimeSeriesKMeansmodel = TimeSeriesKMeans(n_clusters=3, metric="dtw", max_iter=10)model.fit(data) To use soft-DTW instead of DTW, simply set metric="softdtw". ...
Functions in Python You use functions in programming to bundle a set of instructions that you want to use repeatedly or that, because of their complexity, are better self-contained in a sub-program and called when needed. That means that a function is a piece of code written to carry out...
!python -c " import faiss; import numpy as np; x = np.random.random((1000, 321)).astype('float32'); ncentroids = 10; niter = 20; verbose = True; d = x.shape[1]; kmeans = faiss.Kmeans(d, ncentroids, niter=niter, verbose=verbose); kmeans.train(x); " It outputs: Cluste...

Now, let’s go ahead and see how can we have a sequence of numbers in each row with python: depth = 6 for number in range(1, depth): for i in range(1, number + 1): print(i, end=' ') print("") Code Explanation: We start off by initializing the value of depth to be 6....

Putting the theory behind, let’s build some models in Python. We will start with Gaussian before we make our way to categorical and Bernoulli. But first, let’s import data and libraries. Setup We will use the following: Chess games data from Kaggle ...
