Speech Title: Towards Fast-Convergent Federated Learning

Abstract: Federated Learning (FL) is a promising approach that allows for collaborative machine learning across distributed nodes while preserving privacy-sensitive data. It enables local nodes to train a task model under the guidance of a central server, without the need to access end-user data. However, achieving fast convergence in FL is not without its challenges. One of the main obstacles is the presence of non-independent and identically distributed (non-IID) data samples across participating nodes. This discrepancy can slow down model training and necessitate additional communication rounds for FL to converge. Furthermore, each round of information exchange between the server and the local nodes incurs significant communication overhead, requiring orthogonal channel resources for each node. In a network environment with limited radio resources, this can significantly slow down the FL process. Moreover, local nodes often have varying hardware capacities, such as CPU cycle, memory, and power. These resource-constrained nodes can become stragglers, complicating the model learning process. In this talk, I will discuss our recent efforts to overcome these challenges. Our goal is to speed up model convergence in FL within wireless networks, taking into account limited wireless resources, data, and device heterogeneities.

Speech Title: Data Management for Cloud-Edge-Device Collaboration

Abstract: Cloud-Edge-Device (CED) collaboration is the foundation of applications such as intelligent manufacturing and smart cities, and collaborative computing is an important supporting technology. The new computing model of CED collaboration proposes effective integration of CED computing capabilities for data management, achieving comprehensive collaboration of data processing, communication, storage, and other capabilities, bringing challenges such as heterogeneity, high dimensionality, real-time performance, and availability. This talk focuses on these challenging issues and conducts in-depth research on the new data management theories and key technologies of cloud edge collaboration, focusing on the three key scientific issues of polymorphic collaboration, efficient balance, and dynamic availability in cloud edge collaborative data management. The speaker fully leverages the advantages of strong timeliness, high security, and low cost in CED collaborative data management. This talk will introduce the basic concepts, challenges, and exploration of the reporter team in cloud edge collaborative data management.

Speech Title: Rethinking interactive annotation of image data for re-identification task

Abstract: AI's success is largely attributed to "data intelligence" and machine learning, which extracts knowledge, patterns, and models from data. One of the problems that big data and model have faced is that, while powerful and easy to demonstrate, it has been a challenge to make it widely available in a variety of scenarios. In many vertical domain, utilizing fully supervised/weakly supervised models usually perform better than using large models directly. To effectively address practical problems in vertical domain and promote AI's integration with the real economy, it is urgent to fully cooperation between big models and data annotation.

Speech Title: Image Authentication and Tamper Localization

Abstract: Image authentication can be used in many fields, including e-government, e-commerce, national security, news pictures, court evidence, medical image, engineering design, and so on. Since some content-preserving manipulations, such as JPEG compression, contrast enhancement, and brightness adjustment, are often acceptable—or even desired—in practical application, an authentication method needs to be able to distinguish them from malicious tampering, such as removal, addition, and modification of objects. Therefore, the traditional hash-based authentication is not suitable for the application. As for the semi-fragile watermarking technique, it meets the requirements of the above application at the expense of severely damaging image fidelity. In this talk, we propose a hybrid authentication technique based on what we call fragile hash value. The technique can blindly detect and localize malicious tampering, while maintaining reasonable tolerance to conventional content-preserving manipulations. The hash value is derived from the relative difference between each pair of the selected DCT coefficient in a central block and its counterpart which is estimated by the DC values of the center block and its adjacent blocks. In order to maintain the relative difference relationship when the image undergoes legitimate processing, we make a pre-compensation for the coefficients. Finally, we point out the direction using deep leaning technique for image authentication.
