Toward a Robust and Universal Crowd-Labeling Framework
نویسنده
چکیده
One of the main challenges in crowd-labeling is to control for or determine in advance the proportion of low-quality/malicious labelers. We propose methods that estimate the labeler and data instance related parameters using frequentist and Bayesian approaches. All these approaches are based on expert-labeled instance (ground truth) for a small percentage of data to learn the parameters. We also derive a lower bound on the number of expertlabeled instances needed to get better quality labels.

Toward a Robust Crowd-labeling Framework using Expert Evaluation and Pairwise Comparison
Crowd-labeling emerged from the need to label large-scale and complex data, a tedious, expensive, and time-consuming task. One of the main challenges in the crowd-labeling task is to control for or determine in advance the proportion of low-quality/malicious labelers. If that proportion grows too high, there is often a phase transition leading to a steep, non-linear drop in labeling accuracy as...
متن کاملRobust Crowd Labeling Using Little Expertise
Crowd-labeling emerged from the need to label large-scale and complex data, a tedious, expensive, and time-consuming task. But the problem of obtaining good quality labels from a crowd and their integration is still unresolved. To address this challenge, we propose a new framework that automatically combines and boosts bulk crowd labels supported by limited number of “ground truth” labels from ...
متن کاملRobust Anti-Windup Control Design for PID Controllers–Theory and Experimental Verification
This paper addresses an approximation-based anti-windup (AW) control strategy for suppressing the windup effect caused by actuator saturation nonlinearity in proportional–integral–derivative (PID) controlled systems. The effect of actuator constraint is firstly regarded as a disturbance imported to the PID controller. The external disturbance can then be modeled by a linear differential equatio...

ISIS represent portrait of the supra-national youths crowd from different parts of the world including Europe and the U.S.A. This constructed and destructive community, to a great extent, is an outcome of the speedy and universal mobilization of foreign fighters from around the world. World Jihadists’ entrance to the Islamic world and their extremist and defiant inclination is not a new phenome...
