Learning to Represent Programs with Graphs
TLDR
This work proposes to use graphs to represent both the syntactic and semantic structure of code and use graph-based deep learning methods to learn to reason over program structures, and suggests that these models learn to infer meaningful names and to solve the VarMisuse task in many cases. Expand
Extended Two-Dimensional PCA for efficient face representation and recognition
TLDR
A novel method called Extended Two-Dimensional PCA is proposed which is an extension to the original 2DPCA which considers a radius of r diagonals around it and expands the averaging so as to include the covariance information within those diagonal. Expand
Probabilistic Graphical Models and Deep Belief Networks for Prognosis of Breast Cancer
TLDR
A probabilistic graphical model (PGM) for prognosis and diagnosis of breast cancer is proposed and extensive experiments using real-world databases show promising results in comparison to Support Vector Machines and k-Nearest Neighbors classifiers, for classifying tumors and predicting events like recurrence and metastasis. Expand
A Markov Game model for valuing actions, locations, and team performance in ice hockey
TLDR
Model validation shows that the total team action and state value both provide a strong indicator predictor of team success, as measured by the team’s average goal ratio. Expand
Recognizing Combinations of Facial Action Units with Different Intensity Using a Mixture of Hidden Markov Models and Neural Network
TLDR
An accurate real-time sequence-based system for representation and recognition of facial AUs is presented and it is robust to illumination changes and it can represent the temporal information involved in formation of the facial expressions. Expand
Image Caption Generation with Hierarchical Contextual Visual Spatial Attention
TLDR
Experimental results on MS-COCO dataset show that the architecture outperforms the state-of-the-art and the dynamic spatial attention mechanism considers the spatial context of the image regions. Expand
Extended Two-Dimensional PCA for efficient face representation and recognition
TLDR
A novel method called Extended Two-Dimensional PCA is proposed which is an extension to the original 2DPCA which considers a radius of r diagonals around it and expands the averaging so as to include the covariance information within those diagonsals. Expand
Relative facial action unit detection
This paper presents a subject-independent facial action unit (AU) detection method by introducing the concept of relative AU detection, for scenarios where the neutral face is not provided. We… Expand
Multimodal Neural Graph Memory Networks for Visual Question Answering
TLDR
A new neural network architecture, Multimodal Neural Graph Memory Networks (MN-GMN), for visual question answering that rivals the state-of-the-art models on Visual7W, VQA-v2.0, and CLEVR datasets. Expand
Analysis, Interpretation, and Recognition of Facial Action Units and Expressions Using Neuro-Fuzzy Modeling
TLDR
An accurate real-time sequence-based system for representation, recognition, interpretation, and analysis of the facial action units (AUs) and expressions is presented and can develop accurate human-interpretable AU-to-expression converters. Expand
