- The MAPLE lab is releasing the source codes related with our publications at github [url]. We are sincerely inviting everyone who is interested to try them. Feedbacks and pull requests are strongly welcome.
- We propose a Loss-Sensitive GAN (LS-GAN),
and extend it to a generalized LS-GAN (GLS-GAN) in which
Wasserstein GAN is a special case.
We have proved both distributional consistency and generalizability of the LS-GAN
model in a polynomial
sample complexity in terms of the model size and its Lipschitz
constants. See more
details in our paper [pdf].
- You might be interested in taking a look
at an incomplete map of GANs in our view [url].
- Microsoft CNTK is officially supporting LS-GAN. You can make a side-by-side comparison with the other GAN models at https://www.cntk.ai/pythondocs/CNTK_206C_WGAN_LSGAN.html.
- Our paper on "High sensitivity with tiny candidates for Pulmonary Nodule Detection" was accepted by MICCAI 2018.
- The paper "Global versus Localized Generative Adversarial Nets" will
appear in CVPR 2018. We present a new construction of Laplacian-Beltrami operator
to enable semi-supervised learning on manifolds without resorting to Laplacian graphs
as an approximate. We also demonstrate the
state-of-the-art performance on image classiciation tasks.
paper "Interleaved Structured Sparse Convolutional Neural Networks"
will appear in CVPR 2018 to present a new compact CNN model.

have a paper "Interleaved Group Group Convolutions for Deep Neural
accepted by ICCV 2017, where a super compact and fast deep
convolutional model was develop that can be deployed on mobile devices. Two
types of group convolutions, a primal group sparse convolution
a dual point-wise permutation convolution, are developed to make the
model more efficient. [pdf]

"Weekly-Shared Deep Transfer Networks for
Heterogeneous-Domain Knowledge Propagation" has been selected as one
of the four best paper
candidates to be presented at ACM MM 2015.
paper is accepted by ICCV
2015. We developed a novel deep LSTM
model for analyzing human actions, where we explore the differential
structure over memory states to study the dynamic saliency.

2015. Congratulations to Vivek, Rohit, Shiyu and Wei!
In these papers, (1) we developed deep networks to reveal the
brain neural connectivity by aligning time-series
neuron fires that are marked by calcium influx; (2) we
invented a new paradigm
of dynamic model to select and predict sensors and their readings over
time, as compared with the conventional static strategy; and (3) we
