Predicting and Explaining Mobile UI Tappability with Vision Modeling and Saliency Analysis

1 code implementation5 Apr 2022 Eldon Schoop, Xin Zhou, Gang Li, Zhourong Chen, Björn Hartmann, Yang Li

We use a deep learning based approach to predict whether a selected element in a mobile UI screenshot will be perceived by users as tappable, based on pixels only instead of view hierarchies required by previous work.

Screen2Words: Automatic Mobile UI Summarization with Multimodal Learning

2 code implementations7 Aug 2021 Bryan Wang, Gang Li, Xin Zhou, Zhourong Chen, Tovi Grossman, Yang Li

Mobile User Interface Summarization generates succinct language descriptions of mobile screens for conveying important contents and functionalities of the screen, which can be useful for many language-based application scenarios.

You Look Twice: GaterNet for Dynamic Filter Selection in CNNs

no code implementations CVPR 2019 Zhourong Chen, Yang Li, Samy Bengio, Si Si

The concept of conditional computation for deep nets has been proposed previously to improve model performance by selectively using only parts of the model conditioned on the sample it is processing.

Learning Sparse Deep Feedforward Networks via Tree Skeleton Expansion

no code implementations16 Mar 2018 Zhourong Chen, Xiaopeng Li, Nevin L. Zhang

An important characteristic of FNN structures learned this way is that they are sparse.

Learning Latent Superstructures in Variational Autoencoders for Deep Multidimensional Clustering

no code implementations ICLR 2019 Xiaopeng Li, Zhourong Chen, Leonard K. M. Poon, Nevin L. Zhang

We investigate a variant of variational autoencoders where there is a superstructure of discrete latent variables on top of the latent features.

Building Sparse Deep Feedforward Networks using Tree Receptive Fields

no code implementations14 Mar 2018 Xiaopeng Li, Zhourong Chen, Nevin L. Zhang

We use Chow-Liu's algorithm to learn a tree-structured probabilistic model for the units at the current level, use the tree to identify subsets of units that are strongly correlated, and introduce a new unit with receptive field over the subsets.

Learning Parsimonious Deep Feed-forward Networks

no code implementations ICLR 2018 Zhourong Chen, Xiaopeng Li, Nevin L. Zhang

Convolutional neural networks and recurrent neural networks are designed with network structures well suited to the nature of spacial and sequential data respectively.

Sparse Boltzmann Machines with Structure Learning as Applied to Text Analysis

no code implementations17 Sep 2016 Zhourong Chen, Nevin L. Zhang, Dit-yan Yeung, Peixian Chen

We are interested in exploring the possibility and benefits of structure learning for deep models.

Latent Tree Models for Hierarchical Topic Detection

1 code implementation21 May 2016 Peixian Chen, Nevin L. Zhang, Tengfei Liu, Leonard K. M. Poon, Zhourong Chen, Farhan Khawar

The variables at other levels are binary latent variables, with those at the lowest latent level representing word co-occurrence patterns and those at higher levels representing co-occurrence of patterns at the level below.

Progressive EM for Latent Tree Models and Hierarchical Topic Detection

no code implementations5 Aug 2015 Peixian Chen, Nevin L. Zhang, Leonard K. M. Poon, Zhourong Chen

It is as efficient as the state-of-the-art LDA-based method for hierarchical topic detection and finds substantially better topics and topic hierarchies.
