Manitest: Are classifiers really invariant?
Invariance to geometric transformations is a highly desirable property of
automatic classifiers in many image recognition tasks. Nevertheless, it is
unclear to which extent state-of-the-art classifiers are invariant to basic
transformations such as rotations and translations. This is mainly due to the
lack of general methods that properly measure such an invariance. In this
paper, we propose a rigorous and systematic approach for quantifying the
invariance to geometric transformations of any classifier. Our key idea is to
cast the problem of assessing a classifier's invariance as the computation of
geodesics along the manifold of transformed images. We propose the Manitest
method, built on the efficient Fast Marching algorithm to compute the
invariance of classifiers. Our new method quantifies in particular the
importance of data augmentation for learning invariance from data, and the
increased invariance of convolutional neural networks with depth. We foresee
that the proposed generic tool for measuring invariance to a large class of
geometric transformations and arbitrary classifiers will have many applications
for evaluating and comparing classifiers based on their invariance, and help
improving the invariance of existing classifiers.Comment: BMVC 201

i-JEN: Visual interactive Malaysia crime news retrieval system
Supporting crime news investigation involves a mechanism to help monitor the current and past status of criminal events. We believe this could be well facilitated by focusing on the user interfaces and the event crime model aspects. In this paper we discuss on a development of Visual Interactive Malaysia Crime News Retrieval System (i-JEN) and describe the approach, user studies and planned, the system architecture and future plan. Our main objectives are to construct crime-based event; investigate the use of crime-based event in improving the classification and clustering; develop an interactive crime news retrieval system; visualize crime news in an effective and interactive way; integrate them into a usable and robust system and evaluate the usability and system performance. The system will serve as a news monitoring system which aims to automatically organize, retrieve and present the crime news in such a way as to support an effective monitoring, searching, and browsing for the target users groups of general public, news analysts and policemen or crime investigators. The study will contribute to the better understanding of the crime data consumption in the Malaysian context as well as the developed system with the visualisation features to address crime data and the eventual goal of combating the crimes
Guilty By Reason of Insanity: Unforeseen Consequences of California\u27s Deinstitutionalization Policy
Beginning with the passage of the Lanterman-Petris- Short Act in 1969, deinstitutionalization in California has had a devastating effect on the mentally ill. Instead of affording the mentally ill with more rights and protections, the process of shutting down state psychiatric hospitals and impeding psychiatric care for those in need caused a cascade effect leading to an increase of homelessness and incarceration. Over the past four decades, prisons and jails in California have become the de facto state mental hospitals, with severely mentally ill individuals having nearly a four-to-one chance of ending up in jail or prison over a psychiatric facility of some variety. This restructuring of mental health services has contributed to the ever-increasing problem of mass incarceration – a problem that has reached epidemic levels in recent years. To that end, solutions to this problem include: community-based mental health services, reopening some state psychiatric hospitals with greater oversight, funding medical research into improved treatment options, and community education aimed at fostering a greater understanding of mental health issues
