In-Route Nearest Neighbor Queries
Nearest neighbor query is one of the most important operations in spatial databases and their application domains, such as location-based services and advanced traveler information systems . This paper addresses the problem of finding the in-route nearest neighbor (IRNN) for a query object tuple which consists of a given route with a destination and a current location on it. The IRNN is a facil...
متن کاملNearest Neighbors Problem
DEFINITION Given a set of n points and a query point, q, the nearest-neighbor problem is concerned with finding the point closest to the query point. Figure 1 shows an example of the nearest neighbor problem. On the left side is a set of n = 10 points in a two-dimensional space with a query point, q. The right shows the problem solution, s. Figure 1: An example of a nearest-neighbor problem dom...

متن کاملProblem Set 1 K-nearest Neighbor Classification
In this part, you will implement k-Nearest Neighbor (k-NN) algorithm on the 8scenes category dataset of Oliva and Torralba [1]. You are given a total of 800 labeled training images (containing 100 images for each class) and 1888 unlabeled testing images. Figure 1 shows some sample images from the data set. Your task is to analyze the performance of k-NN algorithm in classifying photographs into...
متن کاملApproximate Nearest Neighbor Problem in High Dimensions
We investigate the problem of finding the approximate nearest neighbor when the data set points are the substrings of a given text T . The exact version of this problem is defined as follows. Given a text T of length n, we want to build a data structure that supports the following operation: given a pattern P , find the substring of T that is the closest to P . Since the exact version of this p...
