Evaluation metrics for behaviour modeling
Daniel Jiwoong Im, Iljung Kwak, Kristin Branson
A primary difficulty with unsupervised discovery of structure in large data sets is a lack of quantitative evaluation criteria. In this work, we propose and investigate several met…
Detecting the Starting Frame of Actions in Video
Iljung S. Kwak, Jian-Zhong Guo, Adam Hantman +2
In this work, we address the problem of precisely localizing key frames of an action, for example, the precise time that a pitcher releases a baseball, or the precise time that a c…
Learning Concept Embeddings with Combined Human-Machine Expertise
Michael J. Wilber, Iljung S. Kwak, David Kriegman +1
This paper presents our work on "SNaCK," a low-dimensional concept embedding algorithm that combines human expertise with automatic machine similarity kernels. Both parts are compl…
Cost-Effective HITs for Relative Similarity Comparisons
Michael J. Wilber, Iljung S. Kwak, Serge J. Belongie
Similarity comparisons of the form "Is object a more similar to b than to c?" are useful for computer vision and machine learning applications. Unfortunately, an embedding of p…
