WebFeb 18, 2024 · The use of manifold learning is based on the assumption that our dataset or the task which we are doing will be much simpler if it is expressed in lower dimensions. But this may not always be true. So, dimensionality reduction may reduce training time but whether or not it will lead to a better solution depends on the dataset.

WebClustering algorithms seek to learn, from the properties of the data, an optimal division or discrete labeling of groups of points. Many clustering algorithms are available in Scikit-Learn and elsewhere, but perhaps the simplest to understand is an algorithm known as k-means clustering, which is implemented in sklearn.cluster.KMeans.
