Title: Why Heuristics Work? Three Examples in Machine Learning


Heuristics are widely used in machine learning and data science, from high-resolution imaging, to deep and reinforcement learning (RL). Despite the challenges such as the highly nonconvex landscape in training deep neural networks, simple heuristics are often surprisingly effective in finding high-quality solutions. To gain a deeper understanding of why and how heuristics work well, this talk will discuss three concrete problems. The first is a century-old problem known as phase retrieval that emerges in diverse scientific and engineering applications such as X-ray crystallography, where we are given magnitude-only measurements about an image with its phase information completely missing, and we wish to recover the image. The second is the problem of training a two-layer nonlinear (ReLU) neural network over separable data, in which both the “trainability” as well as the generalization issues will be investigated. The third is about temporal-difference (TD) learning, one of the most key concepts in reinforcement learning, whose non-asymptotic analysis has proved challenging. We describe three simple solutions, and present some theory explaining how and why they work well, as well as some numerical examples and applications.

Title:Privacy Preserving Problems in Deep Learning

Deep learning is increasingly popular, partly due to its widespread application potential, such as in civilian, government and military domains. Given the exacting computational requirements, cloud computing has been utilized to host user data and model. However, such an approach has potential privacy implications. Therefore, we introduce a method to protect user’s privacy in the inference phase of deep learning workflow. Specifically, we use an intermediate layer to separate the entire neural network into two parts, which are respectively deployed on the user device and the cloud server.

Prof. Liang Hu

Tongji University, China

Title:Federated Learning: Basic Concepts, Models and Applications

In recent years, more and more countries have been paying increasing attention to data security and personal privacy, which has direct impact on the socioeconomic development. Federated learning, as a promising AI research area, enables machine learning models to obtain the knowledge from different datasets located in different devices or sites without sharing training data. This allows personal data to remain in local devices or sites, reducing possibility of privacy breaches. In this talk, the speaker will introduce the basic concepts of federated learning and the classification of various federated learning models. After that, two real applications that demand high-level privacy will be introduced, where the federated learning methods are employed to guarantee the data and personal privacy. Firstly, the speaker will present the federated learning on crowdsourced HD mapping. Secondly, the speaker will present the potential application of federated learning on person re-identification.

Active Mask-Box Scoring R-CNN for Sonar Image Instance Segmentation


Instance segmentation task for sonar images is an effective way for underwater target recognition. However, the current instance segmentation models often confront a problem that the positioning accuracy is not well correlated with classification confidence which damages the positioning accuracy. Besides, annotating sonar images is a costly work in terms of time and professional knowledge. To tackle these problems, in this paper, we study the instance segmentation algorithm and propose a novel instance segmentation method called Mask-Box Scoring R-CNN(M-B Scoring R-CNN), and apply it in active learning process. M-B Scoring R-CNN uses a boxIoU head to predict the quality of the bounding boxes. It revises the confidence scores of the NMS step during inference to preserve highquality bounding boxes. To deal with the annotating problem, we propose a triplets-based active learning method with balancedsampling. The triplets-based active learning method evaluates the amount of information of unlabeled samples from the aspects of classification confidence, positioning accuracy and mask quality.

The balanced-sampling method selects hard samples from data set to train model to improve the performance to the greatest extent. The experiments results show that M-B Scoring R-CNN has a noticeable improvement on the instance segmentation performance of sonar images by generating more accurate bounding boxes, and the active learning method can reach a satisfying performance with less labeled samples.

Title: “Machine Learning for Detecting Internet Traffic Anomalies”

Border Gateway Protocol (BGP) enables the Internet data routing. BGP anomalies may affect the Internet connectivity and cause routing disconnections, route flaps, and oscillations. Hence, detection of anomalous BGP routing dynamics is a topic of great interest in cybersecurity. Various anomaly and intrusion detection approaches based on machine learning have been employed to analyze BGP update messages collected from RIPE and Route Views collection sites. Survey of supervised and semi-supervised machine learning algorithms for detecting BGP anomalies and intrusions is presented. Deep learning, broad learning, and gradient boosting decision tree algorithms are evaluated by creating models using collected datasets that contain Internet worms, power outages, and ransomware events.
