Title: Identifying Points of Interest by Self-Tuning Clustering

Abstract:

Mining trip related information from web-scale datasets has received very large amounts of attention recently. Identifying points of interest (POIs) in geo-tagged photos is one of these problems. The problem can be viewed as a standard clustering problem of partitioning two dimensional objects. In this work, we rst study spectral clustering which is first attempt for POIs identification. However, there is no unified clustering parameters for the problem since the features of POIs are immensely varying in di erent metropolitans and locations. To address this, we are intent to study self-tuning technique such that the parameters are tuned automatically in the process.

Besides geographical information, web photos inherently store rich information. These information are mutually influenced each others and should be taken into trip related mining tasks. To address this, we attempt to study reinforcement which constructs the relationship on multiple information by iterative learning. At last, we demonstrate our findings thoroughly by web scale datasets collected from Flickr
