- 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 "Generalized Loss-Sensitive Adversarial Learning with Manifold Margins" was accepted by ECCV 2018, where we present to train the Loss-Sensitive GAN by learning a pull-back mapping from a sample x to its projection z onto the manifold
generated by the GAN. We shall its applications into
generating interpolated edits between images as well as
semi-supervised learning with state-of-the-art performances.
- Our paper on "A Principled Approach to Hard Triplet Generation via Adversarial Nets" was accepted by ECCV 2018,
where we develop a principled way to generate harder yet more
informative triplets to train query and re-identification models.
State-of-the-art performances were demonstrated on the re-id and fine-grained classification problems.
- Dr. Qi is serving as senior TPC member for AAAI 2019.
- 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]

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
