Search with Keywords. Abstract. Conventional spatial queries, such as range search and nearest . neighbor. retrieval, involve only conditions on objects' geometric properties. Today, many modern applications call for novel forms of queries that aim to find objects satisfying both a spatial predicate, and a predicate on their associated texts. For example, instead of considering all the restaurants, a nearest . LECTURE 10. Classification. . k-nearest neighbor classifier. . Naïve Bayes. . Logistic Regression. . Support Vector Machines.
