Greedy algorithm - Study guides, Class notes & Summaries

Suppose we have a set of activities to schedule among lecture halls, where any activity can take place in any lecture hall. We wish to schedule everything using as few halls as possible. Give an efficient greedy algorithm to determine which activities occur in which halls. Correct Answer We have free halls F and busy halls B. Sort classes by start time. For each new start time, remove a hall from F, schedule class, add to B. If F is empty, add a new hall to F. Suppose we start using the mth lect...

C950 Overview A. Identify a named self-adjusting algorithm that you used to create your own program to deliver the packages In this project I’m using a Nearest Neighbor algorithm and a Greedy algorithm. Using Greedy algorithm, I’m iterating over packages and fully loading truck 1 and truck 2 and the remaining packages go into truck 3. Then I’m using Nearest Neighbor algorithm by looping through packages in a truck and determining lowest distance from current start position to eac...

Factor Based Models classification, clustering, regression. Implicitly assumed that we have a lot of factors in the final model Why limit number of factors in a model? 2 reasons overfitting: when # of factors is close to or larger than # of data points. Model may fit too closely to random effects simplicity: simple models are usually better Classical variable selection approaches 1. Forward selection 2. Backwards elimination 3. Stepwise regression greedy algorithms...

Overfitting If you have less data than features, what is likely to occur? Fitting random effects What can too many factors lead to? Simple Models Reducing variables will result in Forbidden Factors Things that cannot be used due to legal requirements Exploration Gathering more data to develop a better model Exploitation Using data sooner to get less accurate, but more immediate results No factors Forward selection starts with what look for ...
