Communication overhead is a significant challenge in distributed deep learning (DDL) training, often hindering efficiency. While existing solutions like gradient compression, compute/communication overlap, and layer-wise flow scheduling have been proposed,...

The prominent role of mobile apps in daily life has underscored the need for robust quality assurance, leading to the development of various automated Android Graphical User Interface (GUI) testing approaches. Code coverage and fault detection are two ...

As cloud computing advances, datacenter networks (DCNs) face unprecedented pressure due to the increasing prevalence of high bandwidth and low delay applications. Current reliable transmission protocols such as TCP harness packet loss, network ...

Java decompilers are programs that perform the reverse process of Java compilers, i.e., they translate Java bytecode to Java source code. They are essential for reverse engineering purposes and have become more sophisticated and reliable over the years. ...

Deep predictive models have been widely employed in software engineering (SE) tasks due to their remarkable success in artificial intelligence (AI). Most of these models are trained in a supervised manner, and their performance heavily relies on ...

As the scale and complexity of Android applications continue to grow in response to increasing market and user demands, quality assurance challenges become more significant. While previous studies have demonstrated the superiority of Reinforcement ...

Static analyzers play a critical role in program defects and security vulnerabilities detection. Despite their importance, the widespread adoption of static analysis techniques in industrial development faces numerous obstacles, among which the high rate ...

In current Data center Networks (DCNs), Equal-Cost Multipath (ECMP) is a default load-balancing scheme. However, using ECMP may result in the rapid growth of Flow Completion Time (FCT) due to its well-known drawbacks. In order to solve ...

In recent years, online data-intensive (OLDI) applications have become particularly common in data center networks (DCNs), such as web search, advertisement systems, and distributed machine learning. OLDI applications have strict ...

Preferences, the setting options provided by Android, are an essential part of Android apps. Preferences allow users to change app features and behaviors dynamically, and therefore their impacts need to be considered when testing the apps. Unfortunately, ...

The lifecycle models of Android components such as Activities and Fragments predefine the possible orders in which the components' callback methods will be invoked during app executions. Correspondingly, resource utilization operations performed by ...

Explicit Congestion Notification (ECN) has been widely employed in production datacenter networks (DCNs) to deliver high throughput and low latency communications. Despite being successful, the drawback of ECN-based transports is that ...

Due to the increasing variety of encryption protocols and services in the network, the characteristics of the application are very different under different protocols. However, there are very few existing studies on encrypted application classification ...

• Human knowledge is valuable for generating tests to exercise complex functionalities.

The last decade has seen a vast proliferation of mobile apps. To improve the reliability of such apps, various techniques have been developed to automatically generate tests for them. While such techniques have been proven to be useful ...

Preferences, the setting options provided by Android, are an essential part of Android apps. Preferences allow users to change app features and behaviors dynamically, and therefore, need to be thoroughly tested. Unfortunately, the specific preferences ...

Automatic and accurate pulmonary nodule segmentation in lung Computed Tomography (CT) volumes plays an important role in computer-aided diagnosis of lung cancer. However, this task is challenging due to target/background voxel imbalance and the ...

Efficiently answering XML keyword queries has attracted much research effort in the last decade. The key factors resulting in the inefficiency of existing methods are the common-ancestor-repetition (CAR) and visiting-useless-nodes (VUN) problems. To ...

TCP incast usually happens when a receiver requests the data from multiple senders simultaneously. This many-to-one communication pattern constantly appears in the data center networks due to the data are stored at multiple servers. With Software ...

In this paper, we adopt a multimodal emotion recognition framework by combining eye movements and electroencephalography (EEG) to enhance emotion recognition. The main contributions of this paper are twofold. a) We investigate sixteen eye movements ...

Given a query string Q, an edit similarity search finds all strings in a database whose edit distance with Q is no more than a given threshold τ. Most existing methods answering edit similarity queries employ schemes to generate string subsequences as ...
