Convex optimization Study guides, Class notes & Summaries

Let C  Rn be a convex set, with x1; : : : ; xk 2 C, and let 1; : : : ; k 2 R satisfy i  0, 1 +


+ k = 1. Show that 1x1 +


+ kxk 2 C. (The denition of convexity is that this holds for k = 2; you must show it for arbitrary k.) Hint. Use induction on k. Solution. This is readily shown by induction from the denition of convex set. We illustrate the idea for k = 3, leaving the general case to the reader. Suppose that x1; x2; x3 2 C, and 1 + 2 + 3 = 1 with 1; 2; 3  0. ...

ISYE 6501 Mid Term 1 with 100% verified answers What is modeling? - correct answer Describing a real life situation mathematically Model - correct answer Mathematical approaches to solving analytics problems 1. Regression for ex. can be called the model of choice. 2. If more detail (descriptive and numerical), the use of, for ex. Regression, can be called the model. 3. The actual values and output along with 1 and 2 can be referred to as the model. Cross Cutting Con...

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...
