Lexical and hierarchical topic regression

by {viet-an Nguyen, Jordan Boyd-graber, Philip Resnik, Viet-an Nguyen, Jordan Boyd-graber, Philip Resnik - In Neural Information Processing Systems , 2013
"... Inspired by a two-level theory from political science that unifies agenda setting and ideological framing, we propose supervised hierarchical latent Dirichlet alloca-tion (SHLDA), which jointly captures documents ’ multi-level topic structure and their polar response variables. Our model extends the ..."

SHLDA improves prediction on political affiliation and sentiment tasks in addition to providing insight into how

Label Configuration Priors for Continuous Multi-Label Optimization Label Configuration Priors for Continuous Multi-Label Optimization

by Technische Universität München, Technische Universität, Mohamed Souiai, Evgeny Strekalovskiy, Nieuwenhuis Daniel Cremers, Mohamed Souiai, Evgeny Strekalovskiy, Claudia Nieuwenhuis, Daniel Cremers
"... We propose a general class of label configuration pri-ors for continuous multi-label optimization problems. In contrast to MRF-based approaches, the proposed frame-work unifies label configuration energies such as minimum description length priors, co-occurrence priors and hier-archical label cost p ..."

Hierarchical planning about goals and commitments

by Pankaj R. Telang, Felipe Meneguzzi, Munindar P. Singh - In Proceedings of the 12th International Joint Conference on Autonomous Agents and MultiAgent Systems (AAMAS). St , 2013
"... We consider the problem of relating an agent’s internal state (its beliefs and goals) and its social state (its commitments to and from other agents) as a way to develop a compre-hensive account of decision making by agents in a multi-agent system. We model this problem in terms of hier-archical tas ..."

Implications of Smoothing on Statistical Multiplexing of H.264/AVC and SVC Video Streams

by Geert Van Der Auwera, Martin Reisslein
"... Abstract—While the hierarchical B frames based Scalable Video Coding (SVC) extension of the H.264/AVC standard achieves sig-nificantly improved compression over the initial H.264/AVC codec, the SVC video traffic is significantly more variable than H.264/AVC traffic. The higher traffic variability of ..."

increased smoothing delay and increased statistical multiplexing performance for both H.264/AVC, which employs classical B frames, and H.264 SVC, which employs hier-archical B frames. We similarly identify the buffer sizes for the buffered multiplexing of unsmoothed H.264 SVC, H.264/AVC, and MPEG-4 Part 2

A Review of Lynn C. Robertson’s (2004) ‘‘Space, Objects, Minds, and Brains’’

by Reviewed Simon, M. Mccrea, Phd Neuro-opthalmology
"... As Dr Robertson alludes to despite the fact that ‘‘what’ ’ and ‘‘where’’ have entered colloquial language sur-prisingly little has been published on how these 2 pathways could possibly interact to define space and objects. Moreover, this well-accepted dicho-tomy is questioned implicitly from a funct ..."

Robertson’s theoretical text proposes that spaces and objects are nested within hier-archical space-object representation reference frames that interact at the most basic levels of perception. Her thesis is that contemporary under-standing of object and space percep-tual organization

Chapel Hill)

by Jan-michael Frahm, Friedrich Fraundorfer, Changchang Wu, David Gallup
"... The topic of this paper is wide area structure from motion. We first de-scribe recent progress in obtaining large-scale 3D visual models from images. Our approach consists of a multi-stage processing pipeline, which can process a recorded video stream in real-time on standard PC hardware by leveragi ..."

In addition, we also briefly discuss some additional work related to absolute scale estimation and multi-camera calibration. i 1.
