Title: Trustworthy Multimodal Machine Learning
Abstract: Multi-modal artificial intelligence technology is being widely used in smart medical care、Unmanned systems and other important fields，Accurate design、Reliable multi-modal learning technology becomes key to supporting important applications。Multimodal data provides rich Bet365 for intelligent system decision-making，Enable multi-modal intelligent systems to “listen and understand”，Improve classification and prediction accuracy。However，In many cost-sensitive scenarios，The credibility of multi-modal fusion and decision-making is often more important。For multi-modal classification tasks，Traditional methods usually assume that the quality and task correlation of each modality are stable。But actually，For different samples or in different scenarios，The quality of the modality and the relevance of the task are often dynamic。As in a multi-sensor scenario，RGB images are more effective in good light，Near-infrared images can provide more important Bet365 in difficult visual situations。This article uses uncertainty to model this dynamic、Integrating multimodal Bet365 using an improved evidence fusion strategy。The paper is titled Trusted Multi-View Classification ，Now ICLR 2021，TPAMI included。Based on this，Not only can we obtain more stable classification results when the modal quality changes dynamically，Also able to estimate decision-making confidence，And conduct modal-level traceability of classification results and classification confidence。Overall，The proposed method is used in multi-modal collaborative learning (listening and understanding)，Evidence estimation for different modalities (trust and evidence)，Thus supporting the reliability and stability of integration and decision-making。

Title: Co-design of high-performance algorithms and architecture for Bet365
Summary: Recent，Bet365 (GNN) extends deep learning to the learning of graph-structured data，And demonstrated its powerful graph representation learning capabilities on many tasks。Typical Bet365 models mostly use neighborhood message propagation mechanism，Update the characteristics of the target node by aggregating the characteristics of neighbor nodes。Pass analysis，We found that a simple implementation of the neighborhood message propagation mechanism will lead to a large amount of redundant computation and redundant communication overhead。This report mainly introduces some of our research work on high-performance graph neural networks。We remove redundancy in the calculation process through the co-design of algorithms and architecture，Accelerate graph neural networks。Compared to current Bet365 accelerators，The Bet365 accelerator we proposed brings considerable acceleration ratio and greatly reduces energy consumption without losing network accuracy。
