Web11 jul. 2024 · Project description mixem is a pure-python implementation of the Expectation-Maximization (EM) algorithm for fitting mixtures of probability distributions. It works in Python 2 and Python 3 (tested with 2.7 and 3.5.1) and uses few dependencies (only NumPy and SciPy). Features Easy-to-use and fully-documented API WebOptimization is the branch of mathematics focused on finding extreme values (max or min) of functions. Optimization tools will appear in many places throughout this course, including: Building economic models in which individuals …
