Building simpler models with fewer factors helps avoid which problems? A. Overfitting B. Low prediction quality C. Bias in the most important factors D. Difficulty in interpretation A. Overfitting D. Difficulty of interpretation Two main reasons to limit # of factors in a model. 1. Overfitting 2. Simplicity When is overfitting likely to happen? When the number of factors is close to the number of data points. How does using a # of factors that is close to the number of data points ca...

Classification: What is it? What are the types? Classification groups things into discrete categories. The types of classification are hard classification and soft classification. Hard Classification vs Soft Classification Hard: 100% separation between groups Soft: minimize misclassifications where possible Margin vs Accuracy Trade Off A small margin for error reduces your chances of misclassifying known data points but increases your chances of misclassifying unknown data points. A...

when might overfitting occur when the # of factors is close to or larger than the # of data points causing the model to potentially fit too closely to random effects Why are simple models better than complex ones less data is required; less chance of insignificant factors and easier to interpret what is forward selection we select the best new factor and see if it's good enough (R^2, AIC, or p-value) add it to our model and fit the model with the current set of factors. Then at the ...

actor 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 Backward elimination v...

What do descriptive questions ask? What happened? (e.g., which customers are most alike) What do predictive questions ask? What will happen? (e.g., what will Google's stock price be?) What do prescriptive questions ask? What action(s) would be best? (e.g., where to put traffic lights) What is a model? Real-life situation expressed as math. What do classifiers help you do? differentiate What is a soft classifier and when is it used? In some cases, there won't be a line that separates a...

1-norm Similar to rectilinear distance; measures the straight-line length of a vector from the origin. If z=(z1,z2,...,zm) is a vector in an m-dimensional space, then it's 1-norm is square root(|

1. A wet chemical kitchen hood fire suppression system is primarily designed to extinguish fires involving: A) Class A only B) Class B only C) Class K D) Class C Answer: C Rationale: Class K fires involve cooking oils and fats common in commercial kitchens. Wet chemical agents saponify the oils, creating a foam layer that cools and seals off oxygen. NFPA 17A specifically addresses Class K protection. 2. What is the primary mechanism by which wet chemical agents extinguish a grease fir...
