Communicative Intent, Context, and Impact of Social Images in Mass Media

Advances in information technologies and the proliferation of digital media have generated an enormous amount of "multi-modal" communicative data and led to new research challenges in scrutinizing large-scale verbal and visual data to understand mass communication activities. The significance of visuals in communication and persuasion has been well acknowledged by researchers in media psychology but it has not been attempted to systematically study its effects due to the lack of a computational framework to automatically process massive visual data.

In this talk I will discuss the concrete development of a novel computational model that predicts social dimensions of images, i.e., high-level emotional perceptions arisen from an image, from the basis of syntactic scene attributes. This hierarchical model leverages existing techniques in computer vision and infers higher-level, latent, "communicative intents" of images through association with various scene components. I will also present the result of a case analysis in which I tracked the visual favorability of the U.S. President, Barack Obama, in newspaper photographs over last 5 years and discovered a strong correlation between the visual depiction from mass media and the public opinion. The approach demonstrates its utility as a new research tool in computational social science, which systematically measures perceptual signals from visual cues in massive datasets and verifies hypotheses in media studies such as agenda-setting.

UCLA Statistics Gives Back to the Community

Img 3012

On Saturday, October 4 about 30 of our undergrads, grads, faculty and staff volunteered at the Los Angeles Regional Food Bank for our 2nd annual UCLA Statistics volunteer day. We teamed with several local high schools and colleges to move, sort, box, pack and count about 77,000 pounds of fruit. It was a fun and fulfilling event for all involved.

Professor Emeritus James MacQueen Has Passed Away

It is with much sadness that we announce of the passing of Professor Emeritus James MacQueen.  Professor MacQueen passed away on July 15 at the age of 85 after a long illness.

Professor MacQueen joined the faculty of UCLA’s Graduate School of Management in 1962 and was named a full professor in 1970. Prior to joining our faculty, Professor MacQueen had a distinguished career that included academic appointments at the University of Oregon and University of California, Berkeley. He earned his bachelor’s degree in psychology at Reed College in 1952 and his master’s of science and Ph.D., both in psychology, from the University of Oregon in 1954 and 1958 respectively.
 
Professor MacQueen’s research focused on providing mathematical formulations of human processes. In his first paper, he investigated a large class of optimal stopping problems. This paper contains the first treatment of the house-hunting problem, also called in economics the job search problem or the problem of selling an asset. This has spawned a large area of research. He was also a pioneer in the development of “K-means,” a method of detecting clusters in multivariate data. Professor MacQueen’s other areas of interest include density estimation and Markov processes.

Colleagues have described him as being outgoing, humble, without ego and always willing to give credit to others. Professor MacQueen excelled in providing fresh ideas for problems that needed to be solved. He loved the outdoors, particularly hiking in the Bighorn Mountains of Wyoming.  He was an avid player of Kriegspiel, a form of chess without seeing the opponent's moves.

Professor MacQueen is survived by his wife, Ann, their three children, Donald, Kate and Mary, and five grandchildren.

Paper Analyzing Effect of Images in the Media is Reported in the BloombergView

Congratulations to Jungseock Joo, Weixin Li, Francis F. Steen, and Song-Chun Zhu as their work, “Visual Persuasion: Inferring Communicative Intents of Images”, was both presented at IEEE CVPR 2014 and reported in the BloombergView. Their paper analyzed huge numbers of political images in the media in order to determine their likely effects on audiences. It brings together the tools of statistics and machine learning to analysis in political science.
