Imperial College London – Department of Computing MSc in Computing Science 580: Algorithms Assessed Coursework 2 1. In this question you are asked to create solutions to the problem of determining whether all the numbers in a given sequence are distinct. Each part of the question sets different requirements on the solution. The general problem
1 The Assignment 1 Specification and Marking Criteria A Simplified Remote Invocation Framework Java RMI (Remote Method Invocation, reference Chapter 5 of the textbook and Week-3 lecture) enables the local invocation and remote invocation use the same syntax to implement a generic remote server like the Compute Engine example in Week-3 lecture slides. However, Java

L20 – Neural Networks k-means clustering (recap) • Idea: try to estimate k cluster centers by minimizing “distortion” • Define distortion as: • rnk is 1 for the closest cluster mean to xn. • Each point xn is the minimum distance from its closet center. • How do we learn the cluster means? • Need
