Federated Learning for Non-IID Data: From Theory to Algorithm
Federated learning suffers from terrible generalization performance because the model fails to utilize global information over all clients when data is non-IID (not independently or identically distributed) partitioning. Meanwhile, the theoretical ...
Fixed-Price Diffusion Mechanism Design
We consider a fixed-price mechanism design setting where a seller sells one item via a social network. Each buyer in the network has a valuation of the item independently derived from a given continuous distribution. Initially, the seller can only ...
A Study of Misinformation Games
A common assumption in game theory is that players have a common and correct (albeit not always complete) knowledge with regards to the abstract formulation of the game. However, in many real-world situations it could be the case that (some of) ...
Influence-Driven Explanations for Bayesian Network Classifiers
We propose a novel approach to building influence-driven explanations (IDXs) for (discrete) Bayesian network classifiers (BCs). IDXs feature two main advantages wrt other commonly adopted explanation methods First, IDXs may be generated using the (...
Strategy Proof Mechanisms for Facility Location at Limited Locations
Most studies of facility location problems permit a facility to be located at any position. In practice, this may not be possible. For instance, we might have to limit facilities to particular locations such as at highway exits, close to bus stops,...

A Consistency Enhanced Deep Lmser Network for Face Sketch Synthesis
Existing face sketch synthesis methods extend conditional generative adversarial network framework with promising performance. However, they usually pre-train on additional large-scale datasets, and the performance is still not satisfied. To ...
A Cost-Efficient Framework for Scene Text Detection in the Wild
Scene text detection in the wild is a hot research area in the field of computer vision, which has achieved great progress with the aid of deep learning. However, training deep text detection models needs large amounts of annotations such as ...
A Dueling-DDPG Architecture for Mobile Robots Path Planning Based on Laser Range Findings
Planning an obstacle-free optimal path presents great challenges for mobile robot applications, the deep deterministic policy gradient (DDPG) algorithm offers an effective solution. However, when the original DDPG is applied to robot path planning,...
A Fully Dynamic Context Guided Reasoning and Reconsidering Network for Video Captioning
Visual reasoning and reconsidering capabilities are instinctively executed alternately as people watch a video and attempt to describe its contents with natural language. Inspired by this, a novel network that joints fully dynamic context guided ...
Adaptive Prediction of Hip Joint Center from X-ray Images Using Generalized Regularized Extreme Learning Machine and Globalized Bounded Nelder-Mead Strategy
The prediction of hip joint center (HJC) is an important step in hip dysplasia screening. Existing state-of-the-art identification methods focus on the development of Mose circle, functional and predictive methods. Those approaches extract few ...
Adversarial Training for Image Captioning Incorporating Relation Attention
Image captioning methods with attention mechanism are leading this field, especially models with global and local attention. But there are few conventional models to integrate the relationship information between various regions of the image. In ...
Element Re-identification in Crowdtesting
Software usually provides different GUI layouts for different devices for a better user experience. This increases the workload of testing, so crowdsourced testing is needed to reduce costs. The crowdsourced testing will perform similar test steps ...
Flame and Smoke Detection Algorithm for UAV Based on Improved YOLOv4-Tiny
Aiming at the current YOLOv4-tiny network’s insufficient feature fusion capability and low utilization of feature extraction in flame and smoke detection tasks, a flame and smoke detection algorithm based on improved YOLOv4-tiny is proposed. ...
Magic Mirror Stealth: Interactive Automatic Picture Editing System
This paper builds an interactive automatic picture editing system based on the most advanced algorithms in the field of multi-modality. It removes a specific area or entity in the image according to the natural language expression, which is like a ...
Off-TANet: A Lightweight Neural Micro-expression Recognizer with Optical Flow Features and Integrated Attention Mechanism
Micro-expression recognition is a video sentiment classification task with extremely small sample size. The transience and spatial locality of micro-expressions bring difficulties to constructing large micro-expression databases and designing ...
Pulmonary Nodule Classification of CT Images with Attribute Self-guided Graph Convolutional V-Shape Networks
Accurate identification and early diagnosis of malignant pulmonary nodules are critical to improving the survival rate of lung cancer patients. Recently, deep learning methods have been proved to be successful in computer-aided diagnosis tasks. ...
Semantic Structural and Occlusive Feature Fusion for Pedestrian Detection
Pedestrian detection under occlusion scenes remains a formidable challenge in computer vision. Recently, anchor-free approach has been raised on the object detection and pedestrian detection field, anchor-free detector Center and Scale Prediction (...
VTLayout: Fusion of Visual and Text Features for Document Layout Analysis
Documents often contain complex physical structures, which make the Document Layout Analysis (DLA) task challenging. As a pre-processing step for content extraction, DLA has the potential to capture rich information in historical or scientific ...
An Initial Study of Machine Learning Underspecification Using Feature Attribution Explainable AI Algorithms: A COVID-19 Virus Transmission Case Study
From a dataset, one can construct different machine learning (ML) models with different parameters and/or inductive biases. Although these models give similar prediction performances when tested on data that are currently available, they may not ...
Generation of Environment-Irrelevant Adversarial Digital Camouflage Patterns
Digital camouflage is the most common and effective means to combat military reconnaissance. Traditional digital camouflage generation methods must regenerate camouflage images according to the current environment. When the environment changes, ...
