Uncertainty Modeling in Deep Learning: A Study on Distribution Shift in Knowledge Graph Embedding

Abstract:

Uncertainty modeling is a very old topic, but its integration into deep learning just starts only in recent years. This presentation briefly reviews the uncertainties in different phases of learning, from the perspectives of data, model, and prediction respectively. Focusing on the problem of distribution shift of entity feature in embedding space, we developed a module of handling uncertainty, which can be regarded as a means of data augmentation for performance promotion on inductive knowledge graph embedding tasks. Extensive experiments demonstrate that our developed model outperforms previous state-of-the-art baseline models on inductive link prediction tasks, which again confirms that the quantification of uncertainty with appropriate modeling can lead to a significant improvement of performance from the view of knowledge graph embedding.

Towards Trustworthy Federated Learning for Large Language Models

Abstract: Federated Learning (FL) presents a groundbreaking approach to training machine learning models using decentralized data while enhancing privacy and security. This method is particularly advantageous for Large Language Models (LLMs) that are data-intensive and computationally demanding. By leveraging a decentralized learning framework, Trustworthy FL addresses key challenges in data privacy, security, and the utilization of distributed data sources effectively.

This presentation will begin by introducing “FedLab,” a versatile and communication-efficient FL toolkit, alongside “FedLegal,” an evaluation benchmark designed specifically for the legal sector to assess federated learning applications. Addressing the susceptibility to privacy attacks in federated learning, the talk will provide empirical evidence demonstrating FL’s effectiveness in safeguarding privacy within language models. To further enhance privacy protections against semi-honest servers, a novel neural network-based encoding aggregation method will be discussed to mitigate gradient leakage attacks. Moreover, the presentation will explore a secure multi-party computation-based solution for preserving privacy during the inference phase of language models.
