Rachmaninoff the most innovative of 18th and 19th century composers according to network science
Rachmaninoff, followed by Bach, Brahms and Mendelssohn, was the most innovative of the composers who worked during the Baroque, Classical and Romantic eras of music (1700 to 1900) according to a study published in the open access journal EPJ Data Science. A team of researchers from KAIST (Korea Advanced Institute of Science and Technology), calculated novelty scores for 900 classical piano compositions written by 19 composers between approximately 1700 and 1900. The scores were based on how musical compositions differed from all prior pieces of piano music and how they differed from previous piano works by the same composer. The authors found that composers from the Romantic era (1820 to 1910) tended to have high novelty scores. The authors from the Graduate School of Culture Technology at KAIST created a computer model which divided each composition into segments called ‘codewords’. Each ‘codeword’ consisted of all of the notes played together at a given time. Sequences of ‘codewords’ were then compared between compositions. The similarities between the sequences were used to create novelty scores for each composer and to determine the extent to which composers influenced each other. Juyong Park, the corresponding author, said: “Our model allows us to calculate the degree of shared melodies and harmonies between past and future works and to observe the evolution of western musical styles by demonstrating how prominent composers may have influenced each other. The period of music we studied is widely credited for having produced many musical styles that are still influential today.” The model distinguished each new musical period from the one before it by the rise of newly dominant and highly influential composers that indicated dramatic shifts in musical styles. The authors found that compositions from the Classical period (1750 to 1820) tended to have the lowest novelty scores. During this period Haydn and Mozart were highly influential but were later overtaken by Beethoven during the Classical-to-Romantic transitional period. The most innovative composer, indicated by the highest combined novelty score, was Rachmaninoff. His work during the Romantic era was novel when compared to the compositions of the other 18 composers included in the study, and his later works were novel compared to his earlier works. Lower novelty did not necessarily correlate with low influence. Beethoven was ranked in the lower half of novelty scores yet was the most influential composer during the Romantic period (1820 to 1910) and is widely considered one of the greatest composers of all time. Dr. Park said: “While novelty is necessary in a creative work it cannot account for all the creative and artistic qualities that go into creating melodies and harmonies that spread to later generations of composers. That may be why being more novel did not necessarily result in composers being more influential.” The authors suggest that their method could be applied to narrative or visual artworks by creating codewords from groups of words or colours and shapes. However, they caution that as only piano compositions were included in their analysis, it is unknown whether including all works by the 19 composers would have resulted in another composer being identified as the most original.

Image Analysis to Automatically Quantify Gender Bias in Movies
Many commercial films worldwide continue to express womanhood in a stereotypical manner, a recent study using image analysis showed. A KAIST research team developed a novel image analysis method for automatically quantifying the degree of gender bias in films. The ‘Bechdel Test’ has been the most representative and general method of evaluating gender bias in films. This test indicates the degree of gender bias in a film by measuring how active the presence of women is in a film. A film passes the Bechdel Test if the film (1) has at least two female characters, (2) who talk to each other, and (3) their conversation is not related to the male characters. However, the Bechdel Test has fundamental limitations regarding the accuracy and practicality of the evaluation. Firstly, the Bechdel Test requires considerable human resources, as it is performed subjectively by a person. More importantly, the Bechdel Test analyzes only a single aspect of the film, the dialogues between characters in the script, and provides only a dichotomous result of passing the test, neglecting the fact that a film is a visual art form reflecting multi-layered and complicated gender bias phenomena. It is also difficult to fully represent today’s various discourse on gender bias, which is much more diverse than in 1985 when the Bechdel Test was first presented. Inspired by these limitations, a KAIST research team led by Professor Byungjoo Lee from the Graduate School of Culture Technology proposed an advanced system that uses computer vision technology to automatically analyzes the visual information of each frame of the film. This allows the system to more accurately and practically evaluate the degree to which female and male characters are discriminatingly depicted in a film in quantitative terms, and further enables the revealing of gender bias that conventional analysis methods could not yet detect. Professor Lee and his researchers Ji Yoon Jang and Sangyoon Lee analyzed 40 films from Hollywood and South Korea released between 2017 and 2018. They downsampled the films from 24 to 3 frames per second, and used Microsoft’s Face API facial recognition technology and object detection technology YOLO9000 to verify the details of the characters and their surrounding objects in the scenes. Using the new system, the team computed eight quantitative indices that describe the representation of a particular gender in the films. They are: emotional diversity, spatial staticity, spatial occupancy, temporal occupancy, mean age, intellectual image, emphasis on appearance, and type and frequency of surrounding objects. Figure 1. System Diagram Figure 2. 40 Hollywood and Korean Films Analyzed in the Study According to the emotional diversity index, the depicted women were found to be more prone to expressing passive emotions, such as sadness, fear, and surprise. In contrast, male characters in the same films were more likely to demonstrate active emotions, such as anger and hatred. Figure 3. Difference in Emotional Diversity between Female and Male Characters The type and frequency of surrounding objects index revealed that female characters and automobiles were tracked together only 55.7 % as much as that of male characters, while they were more likely to appear with furniture and in a household, with 123.9% probability. In cases of temporal occupancy and mean age, female characters appeared less frequently in films than males at the rate of 56%, and were on average younger in 79.1% of the cases. These two indices were especially conspicuous in Korean films. Professor Lee said, “Our research confirmed that many commercial films depict women from a stereotypical perspective. I hope this result promotes public awareness of the importance of taking prudence when filmmakers create characters in films.” This study was supported by KAIST College of Liberal Arts and Convergence Science as part of the Venture Research Program for Master’s and PhD Students, and will be presented at the 22nd ACM Conference on Computer-Supported Cooperative Work and Social Computing (CSCW) on November 11 to be held in Austin, Texas.

A Glance at the 2017 KAIST Literary Awards Ceremony
Since KAIST is a university specializing in science and engineering, people may think that the students rarely engage in literary activities. But KAIST students also excel in writing literature. The 23rd KAIST Literary Award Ceremony was held on December 14 on the KAIST main campus. The award was established in 1995 to encourage students’ creative activities and to promote literary attainment. It is open to all KAIST students from undergraduate to masters and PhD students.

Professor Woontack Woo Demonstrates an Optical Platform Technology for Augmented Reality at Smart Cloud Show
Professor Woontack Woo of the Graduate School of Culture Technology at KAIST participated in the Smart Cloud Show, a technology exhibition, hosted by the university’s Augmented Human Research Center and presented the latest development of his research, an optical platform system for augmented reality. This event took place on September 16-17, 2015 at Grand Seoul Nine Tree Convention Center in Seoul. At the event, Professor Woo introduced a smart glass with an embedded augmented reality system, which permits remote collaboration between an avatar and the user’s hand. The previous remote collaboration was difficult for ordinary users to employ because of its two-dimensional screen and complicated virtual reality system. However, with the new technology, the camera attached to artificial reality (AR) glasses recognizes the user’s hand and tracks it down to collaborate. The avatar in the virtual space and the user’s hand interact in real space and time. The key to this technology is the stable, real-time hand-tracking technique that allows the detection of the hand’s locations and the recognition of finger movements even in situations of self-occlusion. Through this method, a user can touch and manipulate augmented contents as if they were real-life objects, thereby collaborating remotely with another user who is physically distant by linking his or her movements with an avatar. If this technology is adopted widely, it may bring some economic benefits such as increased productivity due to lower costs for mobility and reduction in social overhead costs from the decrease in the need of traveling long distance. Professor Woo said, “This technology will provide us with a greater opportunity for collaboration, not necessarily restricted to physical travelling, which can be widely used in the fields of medicine, education, entertainment, and tourism.” Professor Woo plans to present his research results on hand-movement tracking and detection at the 12th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI 2015), to be held on October 28-30, 2015, at Kintex in Goyang, Korea. He will also present a research paper on remote collaboration at the ICAT-EGVE 2015 conference, the merger of the 25th International Conference on Artificial Reality and Telexistence (ICAT 2015) and the 20th Eurographics Symposium on Virtual Environments (EGVE 2015), which will take place on October 28-30, 2015 at the Kyoto International Community House, Kyoto, Japan.

Professor Kim Donates W5 Bil. to KAIST
Korea Times 2004.5.21 By Kim Tae-gyu / Staff Reporter A professor from the Korea Advanced Institute of Science and Technology (KAIST) has donated his inherited wealth of 5 billion won to the state-owned institute. The KAIST announced professor Kim Dong-won contributed 5 billion won in properties and cash, which he inherited from his father, who passed away late last year. ``Professor Kim has asked us to spend the contribution in the development of Korea’s science in accordance with the late Kim’s will,’’ said Park Jae-wook, a KAIST spokesman. Park added Kim had tried to remain anonymous, but his identity was revealed by some local newspapers. Kim is currently in the United States as he is out of his post on an interim basis and will come back to Korea in August. Four billion won of the donation will be used to set up scholarships, which will endow 20 million won each to 10 KAIST students every year. The remaining 1 billion won will help invite illustrious scholars to the institute. Adding to the good news for KAIST, Lee Chong-moon, chairman of the U.S.-based venture company Ambex, has also donated 2 billion won. The 76-year-old Lee called for the KAIST to inspire a sprit among students by establishing a management center named after him.
