AdaFlow: Domain-adaptive Density Estimator with Application to Anomaly Detection and Unpaired Cross-domain Translation

ICASSP 2019accepted

We tackle unsupervised anomaly detection (UAD), a problem of detecting data that significantly differ from normal data. UAD is typically solved by using density estimation. Recently, deep neural network (DNN)-based density estimators, such as Normalizing Flows, have been attracting attention. Howeve…

Subspace Structure-Aware Spectral Clustering for Robust Subspace Clustering

ICCV 2019poster

Subspace clustering is the problem of partitioning data drawn from a union of multiple subspaces. The most popular subspace clustering framework in recent years is the graph clustering-based approach, which performs subspace clustering in two steps: graph construction and graph clustering. Although…

Spatio-Temporal Person Retrieval via Natural Language Queries

ICCV 2017poster

In this paper, we address the problem of spatio-temporal person retrieval from videos using a natural language query, in which we output a tube (i.e., a sequence of bounding boxes) which encloses the person described by the query. For this problem, we introduce a novel dataset consisting of videos c…

Common Subspace for Model and Similarity: Phrase Learning for Caption Generation From Images

ICCV 2015poster

Generating captions to describe images is a fundamental problem that combines computer vision and natural language processing. Recent works focus on descriptive phrases, such as "a white dog" to explain the visual composites of an input image. The phrases can not only express objects, attributes, ev…
