NAACL-HLT
1 June 2018

We propose a deep neural framework, termed conversational memory network, which leverages contextual information from the conversation history to classify utterance-level emotions in dyadic conversational videos. Expand

ICON: Interactive Conversational Memory Network for Multimodal Emotion Detection

Devamanyu Hazarika, Soujanya Poria, Rada Mihalcea, E. Cambria, Roger Zimmermann
Computer Science
EMNLP
2018

We propose Interactive COnversational memory Network (ICON), a multimodal emotion detection framework that extracts multimodAL features from conversational videos and hierarchically models the self and inter-speaker emotional influences into global memories. Expand

We propose CASCADE (a ContextuAl SarCasm DEtector) that adopts a hybrid approach of both content and context-driven modeling for sarcasm detection in online social media discussions. Expand

SCADDAR: an efficient randomized technique to reorganize continuous media blocks

A. Goel, C. Shahabi, S. D. Yao, Roger Zimmermann
Computer Science
Proceedings 18th International Conference on Data…
7 August 2002

We propose a technique that meets the objective, while we prove that it also satisfies both restrictions. Expand

SDNDASH: Improving QoE of HTTP Adaptive Streaming Using Software Defined Networking

A. Bentaleb, A. Begen, Roger Zimmermann
Computer Science
ACM Multimedia
1 October 2016

We propose a new software defined networking (SDN) based dynamic resource allocation and management architecture for HAS systems, which aims to alleviate these scalability issues and improve the per-client QoE. Expand

A Survey on Bitrate Adaptation Schemes for Streaming Media Over HTTP

A. Bentaleb, Bayan Taani, A. Begen, C. Timmerer, Roger Zimmermann
Computer Science
IEEE Communications Surveys & Tutorials
2019

In this survey, we present state-of-the-art bitrate adaptation algorithms for HTTP adaptive streaming (HAS). Expand

Viewable scene modeling for geospatial video search

Sakire Arslan Ay, Roger Zimmermann, S. H. Kim
Computer Science
ACM Multimedia
26 October 2008

We propose a novel approach for querying videos based on the notion that the geographical location of the captured scene in addition to the location of a camera can provide valuable information and may be used as a search criterion in many applications. Expand

Canopy transpiration and water fluxes in the xylem of the trunk of Larix and Picea trees — a comparison of xylem flow, porometer and cuvette measurements

1 July 1985

SummaryLeaf gas exchange, transpiration, water potential and xylem water flow measurements were used in order to investigate the daily water balance of intact, naturally growing, adult Larix and… Expand

The multi-rule partial sequenced route query

Haiquan Chen, Wei-Shinn Ku, Min-Te Sun, Roger Zimmermann
Computer Science
GIS '08
5 November 2008

We first prove that MRPSR is NP-hard and then present three heuristic algorithms to search for near-optimal solutions for the MRPSr query. Expand

Modeling Inter-Aspect Dependencies for Aspect-Based Sentiment Analysis
