There is overwhelming evidence suggesting that the real users of IR systems often prefer using extremely short queries (one or two individual words) but they try out several queries if needed. Such behavior is fundamentally different from the process modeled in the traditional test collection-based IR evaluation based on using more verbose queries and only(More)
As mobile and social networking applications continue to proliferate, they also increasingly rely on the collection of an ever wider range of con-textual attributes, location being a prime example. Prior work has shown that people's privacy preferences when it comes to sharing this information are often complex and that expecting users to spend the time(More)
BACKGROUND Machine learning approaches for classification learn the pattern of the feature space of different classes, or learn a boundary that separates the feature space into different classes. The features of the data instances are usually available, and it is only the class-labels of the instances that are unavailable. For example, to classify text(More)
With the rapid advances in technologies such as MEMS sensors, low-power embedded processing and wireless networking, sensor networks are becoming more powerful in terms of data acquisition and processing capabilities. Sensor networks can now be deployed in the physical world for various important applications such as environmental monitoring, weather(More)
Understanding what visual features and representations contribute to human object recognition may provide scaffolding for more effective artificial vision systems. While recent advances in Deep Convolutional Networks (DCNs) have led to systems approaching human accuracy, it is unclear if they leverage the same visual features as humans for object(More)
Civic authorities in many Indian cities have a tough time in garbage collection and as a result there is a pile up of garbage in the cities. In order to manage the situation, it is first required to be able to quantify the issue. In this paper, we address the problem of quantification of garbage in a dump using a two step approach. In the first step, we(More)
