    Title: Computational Models for Multidimensional Annotations of Affect

    Abstract: Affect is an integral aspect of human psychology, it acts as a regulator for all our interactions with external stimuli. Affect includes several related concepts such as sentiment, emotion as well as as higher order constructs such as mood and humor. By its nature, it is highly subjective, with different stimuli leading to different responses in people due to varying personal and cultural artifacts. For example, a specific image or audio clip may evoke different emotions in people depending on their personality. Computational modeling of affective dimensions is an important problem in Artificial Intelligence (AI). It covers a variety of tasks such as sentiment analysis, emotion recognition and opinion mining, which often involve supervised training of models using a large number of labeled data instances. However, training labels are difficult to obtain due to the inherent subjectivity of these constructs. Typical approaches to obtain the training labels include collecting opinions from expert or naive annotators, followed by a suitable aggregation.
    In this dissertation, we will present our contributions towards building computational models for noisy annotations of affect, specifically in the aggregation of multidimensional annotations. We propose latent variable models to capture annotator behaviors using additive Gaussian noise and matrix factorization, leading to more accurate estimates of the underlying ground truth. We then apply the joint matrix factorization model to the task of sentence level estimation of psycholinguistic normatives. Finally, we highlight our ongoing efforts in estimating agreement on multidimensional annotations.

  • USC Reunion Special Event - USC Viterbi Professor Garrett Reisman Meet and Greet

    Fri, Oct 18, 2019 @ 02:00 PM - 02:50 PM

    Viterbi School of Engineering Alumni

    University Calendar


    As part of USC Reunion Weekend, USC Viterbi is hosting a special breakout event on Friday, October 18 from 2:00-2:50 featuring NASA astronaut and USC professor Garrett Reisman.

    As 2019 marks the 50th anniversary of the moon landing, Dr. Reisman will recount the real-life intrigue, dangers and constant excitement that were a daily part of his career in space.

    Dr. Reisman was selected by NASA as a mission specialist astronaut in 1998. His first mission was aboard the Space Shuttle Endeavour, in 2008, which dropped him off for a 95-day mission aboard the International Space Station after which he returned to Earth aboard the Space Shuttle Discovery. His second mission was aboard the Space Shuttle Atlantis, in 2010, which returned him to the Space Station.

    During these missions, Dr. Reisman performed three spacewalks, operated the Space Station Robot Arm and was a flight engineer aboard the Space Shuttle. After leaving NASA in 2011, Dr. Reisman joined SpaceX, which he prepared for human spaceflight as the Director of Space Operations. Currently he is a professor of astronautical engineering at USC, and he continues his work at SpaceX as a senior advisor.
