Speech Title: "Dynamic Ensemble Bayesian Filter for Robust Control of a Human Brain-machine Interface"
Abstract: Brain-machine interfaces (BMIs) aim to provide direct brain control of devices such as prostheses and computer cursors, which have demonstrated great potential for motor restoration. One major limitation of current BMIs lies in the unstable performance due to the variability of neural signals, especially in online control, which seriously hinders the clinical availability of BMIs. We propose a dynamic ensemble Bayesian filter (DyEnsemble) to deal with the neural variability in online BMI control. Unlike most existing approaches using fixed models, DyEnsemble learns a pool of models that contains diverse abilities in describing the neural functions. In each time slot, it dynamically weights and assembles the models according to the neural signals in a Bayesian framework. In this way, DyEnsemble copes with variability in signals and improves the robustness of online control. Online BMI experiments with a human participant demonstrate that, compared with the velocity Kalman filter, DyEnsemble significantly improves the control accuracy (increases the success rate by 13.9% in the random target pursuit task) and robustness (performs more stably over different experiment days). DyEnsemble frames a novel and flexible dynamic decoding framework for robust BMIs, beneficial to various neural decoding applications.

Speech Title: "Human Action Recognition from Skeleton and Video"
Abstract: In this talk, I will talk about two of our recent works about human action recognition. The first is about skeleton-based human action recognition. We proposed a novel Enhanced Discriminative Graph Convolutional Network (ED-GCN) based on the attention mechanism for skeleton-based action recognition. Discriminative channel-wise features are obtained by fusing the Squeeze and Excitation (SE) module to the GCN to selectively enhance the significant features and suppress the non-significant ones. The second is an efficient dual attention SlowFast networks for video action recognition. We proposed a cross-modality dual attention fusion module named CMDA to explicitly exchange spatial–temporal information between two pathways in two-stream SlowFast networks. We also proposed several two-stream efficient SlowFast networks based on well designed efficient 2D networks, such as GhostNet, ShuffleNetV2.

Speech Title: "Research on Optical Coherence Tomography (OCT) –based Fingerprints"
Abstract: Optical coherence tomography (OCT) is a new non-invasive, high-resolution and three-dimensional imaging technology developed in the 1990s. It has been maturely applied in Ophthalmology, dermatology and other fields. However, OCT-based fingerprint research began in 2006. Compared with traditional fingerprints (two-dimensional surface fingerprints, high-resolution fingerprints, and three-dimensional fingerprints), OCT-based fingerprints: 1) can overcome the low-quality image problems caused by the skin status of surface fingerprints (such as dry, wet, stains, etc.), which benefits in improving the recognition accuracy; 2) It can capture sweat glands / pores and other features that can be extracted only on high-resolution fingerprint images, so as to realize alive detection; 3) In essence, it is a kind of three-dimensional fingerprint data containing rich multi-level fingerprint information, which can easily identify false fingerprints without internal fingerprint structure, so as to achieve the purpose of anti-spoofing. Therefore, OCT opens up a new field for fingerprint recognition. This talk will mainly focus on the anti-spoofing technology in OCT-based fingerprints. Firstly, we will review current researches of anti-spoofing technology on OCT-based fingerprint, analyze the existing problems, and report some progress and achievements we have made; Finally, the further direction and expectation of OCT-based fingerprint image is summarized.

Speech Title: "Music-driven Conducting Motion Generation"
Abstract: Although recent studies have successfully generated motion for singers, dancers, and musicians, few have explored motion generation for orchestral conductors. In order to verify the feasibility of applying deep learning models to this task, we construct a large-scale dataset ConductorMotion100, which consists of an unprecedented 100 hours of conducting motion data. Based on the constructed ConductorMotion100 dataset, we designed a novel Music Motion Synchronized Generative Adversarial Network (M2S-GAN). The M2S-GAN is a cross-modal generative network comprising four components: 1) a music encoder that encodes the music signal; 2) a generator that generates conducting motion from the music codes; 3) a motion encoder that encodes the motion; 4) a discriminator that differentiates the real and generated motions. These four components respectively imitate four key aspects of human conductors: understanding music, interpreting music, precision and elegance. The music and motion encoders are first jointly trained by a self-supervised contrastive loss, and can thus help to facilitate the music motion synchronization during the following adversarial learning process. Through visualization, we show that our approach can generate plausible, diverse, and music-synchronized conducting motion. To facilitate future research, the dataset is made public via the 1st Prospective Cup Meta-Intelligent Data Challenge.

Speech Title: "An Application of Neural Networks for Traffic Problems"
Abstract: Traffic congestion is a thorny issue to many large and medium-sized cities, posing a serious threat to sustainable urban development. Recently, intelligent traffic systems (ITS) have emerged as an effective tool to mitigate urban congestion. The key to ITS lies in the accurate forecast of traffic flow. However, the existing forecast methods of traffic flow cannot adapt to the stochasticity and sheer length of traffic flow time series. To solve the problem, this paper relies on deep learning (DL) to forecast traffic flow through time series analysis. The authors developed a traffic flow forecast model based on the bidirectional Long Short-Term Memory Recurrent Neural Network (BLSTM-RNNs) with delay. The proposed model was compared with two classic forecast models, namely, the autoregressive integrated moving average (ARIMA) model and the Long Short-Term Memory Recurrent Neural Network (LSTM-RNNS) model, through long-term traffic flow forecast experiments, using an actual traffic flow time series from Open ITS. The experimental results show that the proposed BLSTM-RNNs network outperformed the classic models in prediction accuracy. Our research discloses the dynamic evolution law of traffic flow and facilitates the decision-making of traffic management.

Speech Title: "A Hybrid Attention-Based CNN LSTM Model for Traffic Flow Prediction"
Abstract: Intelligent transports systems (ITS) of smart cities have been developed to address the traffic management problem caused by a growing number of urban vehicles and increasing traffic congestion. Giving accurate traffic flow prediction plays a pivotal role in a well-functioning ITS. However, such prediction and associated learning of nonlinear spatial-temporal dynamics are challenging due to existence of nonlinearity and stochasticity and has attracted attention of many researchers. In this talk, a discussion on a hybrid, deep-learning model based on attention CNN-LSTM is presented to solve the traffic flow prediction problem. Comparison of the proposed method with counterparts is also discussed, offering some insights into pros and cons of prevalent deep-learning methods in solving the traffic prediction issue.
