Title: Deep Learning in Detection and Recognition

In this seminar, I will introduce our recent works on developing deep
models to solve several computer vision problems, especially focusing
on pedestrian detection and face recognition. Deep models
significantly advance the state-of-the-art on these challenges because
of their capability of automatically learning hierarchical feature
representations from data, disentangling hidden factors, jointly
optimizing key components in a computer vision system, and their
learning capacity. Through examples, I will share our experience on
how to formulate a vision problem with deep learning, and how to
effectively train a deep neural network. Instead of treating a deep
model as a black box, we investigate the connection between deep
models and existing vision systems, such that a lot of insights and
experience accumulated from vision research can be used to develop new
deep models and effective training strategies. Taking pedestrian
detection as an example, pedestrian detection, new layers are designed
to function as part detectors, modeling deformations and inferring the
visibility of body parts. I will also report our results on face
recognition which can be addressed by deep learning in several
different ways.
