[Summary] PhD Proposal: Structured Approaches to Exploring Inter-Personal Relationships in Natural Language Text

A Ph.D. proposal talk by Snigdha Chaturvedi, who is expected to graduate in June 2016. The presentation was terrific covering relationship prediction in movies, novels and MOOCs. Time:  06.30.2015 15:00 to 16:30Location:  AVW 4424URL:  https://talks.cs.umd.edu/talks/1055 In this thesis we propose methods to model inter-personal relationships in text. Due to their inherent social nature, people continuously interact…


It is High Time to Start a Revolution in Tech Interviews

References: On Secretly Terrible (Old) Engineers by Danny Crichton College Examinations: Is Anything Significant? by Ruofei Du Traditional tech interviews are terrible to both employers and potential employees. It is not merely a waste of time, but also a great pressure to both. Almost everyone attended interviews agreed such points, but the fact is: we are…


[SIGGRAPH 2015] Fairy Lights in Femtoseconds

Today Sujal introduced Fairy Lights in Femtoseconds Project by Ochiai et al. to our group. Basically, it is a tangible holographic plasma in the mid-air or water or florescent (plates)! Their SIGGRAPH 2015 paper entitled “Fairy Lights in Femtoseconds: Aerial and Volumetric Graphics Rendered by Focused Femtosecond Laser Combined with Computational Holographic Fields” can be downloaded in arXiv….


Dry Lights – An Experimental Film by French artist Xavier Chassaing

Dry Lights, an experimental film through the visual label Antivj, is brought to us by independent French artist Xavier Chassaing.  In the film, visual effects lead us through a landscape both foreign and familiar feeling.  In Chassaing’s first fully computer-generated project, the music draws you into the electrifying experience while the visual scene engages the…

Tutorial and Resources for Three.js

Three.js is one of a number of free WebGL libraries. First released in April 2010, it has become pretty popular, and includes a huge number of demos. I wanted to know more about its origins, so interviewed its creator, Ricardo Cabello, aka mr.doob, who lives in Spain. Interestingly, I am also largely motivated by Demoscenes when I was…


Tutorial of Ray Casting, Ray Tracing and Ray Marching

Introduction As GPU power is becoming significantly better than CPU, ray casting / tracing and ray marching is widely used in 4k intros and demoscenes to create 3D (interactive) graphics. – Thanks to all the references listed in the end, I learnt so much about and I would like to share with the knowledge to my friends. This tutorial…


Discussion: Startups in Computer Vision

I mainly translated and summarized several people’s discussion from this reference in Chinese. I don’t agree with all of the points and I added some of my own views. To be modest, I still believe in startups like SenseTime, Face++, Cogtu, Linkface, DeepGlint etc. What we discuss here may be a joke for the future. But…


Comparison: Sony SmartEyeglass vs. Google Glass

Sony announced pre-order of its SmartEyeglass Developer Edition in February, 2015 while Google published the Google Glass several years ago and kept updating (though just in January Google halted sales of Glass). Here is my comparison between the two glasses: Spec Comparison SmartEyeglass Google Glass Glass Mass 77g 43g Auxiliary Mass 45g – AR Binocular see-through HUD…


[Talk] Sketch-based 3D Shape Retrieval using Convolutional Neural Networks

Today in CFAR seminar, Dr. Yi Li and his student Fang Wang from Australian National University ented the work on Sketch-based 3D Shape Retrieval using Convolutional Neural Networks. Here is the paper in arXiv. Here is my summary: Yet-another-CNN-application The question for superior performance What if I don’t have 100 GPUs like Google / Facebook? What if I don’t…
