Weakly Supervised Clustering: Learning Fine-Grained Signals from Coarse Labels

Consider a classification problem where we do not have access to labels for individual training examples, but only have average labels over subpopulations. We give practical examples of this setup, and show how these classification tasks can usefully be analyzed as weakly supervised clustering problems. We propose three approaches to solving the weakly supervised clustering problem, including a...

parXXL: A Fine Grained Development Environment on Coarse Grained Architectures

We present a new integrated environment for cellular computing and other fine grained applications. It is based upon previous developments concerning cellular computing environments (the ParCeL family) and coarse grained algorithms (the SSCRAP toolbox). It is aimed to be portable and efficient, and at the same time to offer a comfortable abstraction for the developer of fine grained programs. A...

Coarse-grained information dominates fine-grained information in judgments of time-to-contact from retinal flow

To investigate the relative importance of fine- and coarse-grained structure in the analysis of retinal flow, subjects made estimates of time-to-contact from random dot kinematograms depicting movement towards a flat, sparsely textured surface. Individual display elements moved smoothly away from each other while expanding smoothly in size. By artificially manipulating the rate at which the ind...

A Comparative Study of Coarse - and Fine - Grained Safe RegressionTest

Regression test selection techniques reduce the cost of regression testing by selecting a subset of an existing test suite to use in retesting a modiied program. Over the past two decades, numerous regression test selection techniques have been described in the literature. Initial empirical studies of some of these techniques have suggested that they can indeed beneet testers, but so far, few s...

Coarse- and Fine-Grained Sentiment Analysis of Social Media Text

INTRODUCTION People make judgments about the world around them. They harbor positive and negative attitudes about people, organizations, places, events, and ideas. We regard these types of attitudes as sentiments. Sentiments are private states,1 cognitive phenomena that are not directly observable by others. However, expressions of sentiment can be manifested in actions, including written and s...
