Web19 nov. 2024 · Let’s create some random data for this example using numpy’s randn () function. Plot the data using a histogram and analyze the returned graph for the expected shape. In reality, the data is rarely perfectly Gaussian, but it will have a Gaussian-like distribution and if the sample size is large enough, we treat it as Gaussian. Web6 jan. 2024 · The Gaussian Mixture Model (GMM) is an unsupervised machine learning model commonly used for solving data clustering and data mining tasks. This model relies on Gaussian distributions, assuming there is a certain number of them, each representing a separate cluster. GMMs tend to group data points from a single distribution together.
