A Wrapper Method for Cost-Sensitive Learning via Stratification

Many machine learning applications require classifiers that minimize an asymmetric loss function rather than the raw misclassification rate. We introduce a wrapper method for data stratification to incorporate arbitrary cost matrices into learning algorithms. One way to implement stratification for C4.5 decision tree learners is to manipulate the weights assigned to the examples from different ...

Cost-sensitive Learning for Bidding in Online Advertising Auctions

One of the most challenging problems in computational advertising is the prediction of ad click and conversion rates for bidding in online advertising auctions. State-ofthe-art prediction methods include using the maximum entropy framework (also known as logistic regression) and log linear models. However, one unaddressed problem in the previous approaches is the existence of highly non-uniform...

Online Cost-Sensitive Learning for Efficient Interactive Classification

A lot of practical machine learning applications deal with interactive classification problems where trained classifiers are used to help humans find positive examples that are of interest to them. Typically, these classifiers label a large number of test examples and present the humans with a ranked list to review. The humans involved in this process are often expensive domain experts with lim...

Online Active Learning for Cost Sensitive Domain Adaptation

Active learning and domain adaptation are both important tools for reducing labeling effort to learn a good supervised model in a target domain. In this paper, we investigate the problem of online active learning within a new active domain adaptation setting: there are insufficient labeled data in both source and target domains, but it is cheaper to query labels in the source domain than in the...

A cost effective and sensitive method for the determination of ammonia concentration in nanocrystal mordenite

The reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (MB+) incorporated in nanomordenite and Na-MOR zeolites. The rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than Na-mordenite (Na-MOR) zeolite.Because nanomordenite zeolite with high si...
