CS Colloquium: Mohammad Soleymani (USC-ICT) - What Do Machines Learn in Emotion Recognition from EEG Signals?

Speaker: Mohammed Soleymani, USC-ICT
Talk Title: What Do Machines Learn in Emotion Recognition from EEG Signals?
Series: CS Colloquium
Abstract: Machines that are able to read our emotions and cognitive states make better companions. Emotions are often sensed by their external manifestations such as facial and vocal expressions. Additionally, studies in affective neuroscience have identified a set of emotional neural activities that can be captured by eletroencephalogram (EEG) signals, including asymmetric frontal brain activity and increase in information transfer. Motivated by these findings, a growing number of studies report developing EEG-based emotion recognition systems with promising results. In this talk, I first present my work on recognizing emotions of people watching videos. I then present a follow up study in which we aimed to better understand what machine learns in such scenarios. In the follow up work, we recorded a dataset which includes spontaneous emotions and posed expressions. Our analysis on the data collected in the follow up study demonstrates that the performance of existing EEG-based emotion recognition methods significantly decreases when evaluated across different corpora. We also found that models trained on spontaneous emotions perform well on recognizing mimicked expressions. Our results provide evidence that stimuli-related sensory information and facial electromyogram activities are the main components learned by machine learning models for emotion recognition using EEG signals.
This lecture satisfies requirements for CSCI 591: Research Colloquium. Please note, due to limited capacity, seats will be first come first serve.

NL Seminar- CoQA, A Conversational Question Answering Challenge
Thu, Oct 04, 2018 @ 11:00 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Siva Reddy , Stanford University
Talk Title: CoQA: A Conversational Question Answering Challenge
Series: Natural Language Seminar
Abstract: Humans gather information by engaging in conversations involving a series of interconnected questions and answers. For machines to assist in information gathering, it is therefore essential to enable them to answer conversational questions. In this talk, I will present our work on CoQA, a novel dataset for building Conversational Question Answering systems. CoQA contains 127k questions with answers, obtained from 8k conversations about text passages from seven diverse domains. The questions are conversational, and the answers are free-form text with their corresponding evidence highlighted in the passage. We analyze CoQA in depth and show that conversational questions have challenging phenomena not present in existing reading comprehension datasets, e.g., coreference and pragmatic reasoning. We evaluate strong conversational and reading comprehension models on CoQA. The best system obtains an F1 score of 65.1%, which is 23.7 points behind human performance 88.8 percent, indicating there is ample room for improvement. We launch CoQA as a challenge to the community. See link below.
Biography: Siva Reddy is a postdoc in Computer Science at Stanford University working with Prof. Christopher Manning. His research focuses on enabling natural communication between humans and machines. Prior to the postdoc, he was a Google PhD Fellow at the University of Edinburgh under the supervision of Prof. Mirella Lapata and Prof. Mark Steedman.

CENG Seminar Series

Speaker: Yu Hua, Huazhong University of Science and Technology
Talk Title: Encrypted Non-volatile Main Memory Systems
Abstract: Non-volatile memory (NVM) technologies are considered as promising candidates of the next-generation main memory. However, the non-volatility of NVMs leads to new security vulnerabilities. Memory encryption can be employed to mitigate the security vulnerabilities, but it increases the number of bits written to NVMs due to the diffusion property and thereby aggravates the NVM wear-out induced by writes. To address these security and endurance challenges, we propose DeWrite, a secure and deduplication-aware scheme to enhance the performance and endurance of encrypted NVMs based on a new in-line deduplication technique and the synergistic integrations of deduplication and memory encryption. Specifically, it performs low-latency in-line deduplication to exploit the abundant cache-line-level duplications leveraging the intrinsic read/write asymmetry of NVMs and light-weight hashing. It also opportunistically parallelizes the operations of deduplication and encryption and allows them to co-locate the metadata for high efficiency. DeWrite was implemented on the gem5 with NVMain.
Biography: Dr. Yu Hua is a professor in Huazhong University of Science and Technology. He was Postdoc Research Associate in McGill University in 2009, and Postdoc Research Fellow in University of Nebraska-Lincoln in 2010-2011. He obtained his B.E and Ph.D degrees from Wuhan University respectively in 2001 and 2005. His research interests include file systems, cloud storage systems, non-volatile memory, big data analytics, etc. He publishes multiple papers in conferences and journals, including OSDI, MICRO, FAST, USENIX ATC, ACM SoCC, SC, HPDC, etc. He serves for multiple international conferences, including USENIX ATC, ASPLOS (ERC), SC, ACM SoCC, RTSS, ICDCS, ICCD, INFOCOM, IPDPS, etc. He is the distinguished member of CCF, senior member of ACM and IEEE, and the member of USENIX.

CCI presents Blockfinity's "Bringing Cities on to the Blockchain - Los Angeles"
Thu, Oct 04, 2018 @ 07:00 PM - 09:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Receptions & Special Events
Blockchain is a fast-growing technology with the intent to decentralize bureaucratic processes, create transparent transactions between multiple parties, and optimize enormous databases. The applications are endless when it comes to government, and municipalities, but our goal is to bring the community together to discuss theory, implementation, and case studies of how cities may work with Blockchain.
Let's imagine the changes in social, economic and environmental by ridding of bureaucracy in city infrastructure such as piles of papers, giant traffic jams, documentation errors and double transactions. Join our discussion to understand which cities around the world are implementing blockchain and how, what can be improved, and how would this help us here in Los Angeles.
