Title: A multi-modal deep learning model based automatic Wisconsin Gait Scale scoring system for stroke patients

Abstract: Gait impairments are a common consequence of stroke and assessing gait patterns is crucial for developing personalized rehabilitation programs. The Wisconsin Gait Scale (WGS) is an effective score criterion for evaluating gait quality in stroke patients. However, the manual scoring process is labor-intensive and often subject to biases due to the varying experience levels of the clinic practitioners. Deep learning techniques offer a potential solution to this challenging difficulty. We propose STAT-Net, a novel multi-modal deep learning model inspired by biomechanical properties and comprehensive insights for automatic WGS scoring based on skeleton data collected by the Inertial Measurement Unit (IMU). We also compare the performance of different models on the task to show the superiority of our method.

Title: Transcriptomic, histopathological and radiological deep learning models for cancer subtype classification

Abstract: It is now clear that major human cancers are heterogeneous diseases, which hamper the selection of patients for optimized clinical management and treatment. To dissect the complex cancer heterogeneity, molecular subtyping has been widely adopted as an effective strategy in the last couple of decades. Despite the insights into cancer biology, the conventional cancer subtyping studies were mostly based on conventional machine learning methods applied to transcriptomics data, which lack cross-platform robustness and are not suitable for clinical translation. In this talk, I will first introduce a deep learning framework based on transcriptomic profiles, which is platform independent, robust to missing data, and can be used for single sample prediction. To facilitate clinical implementation, I will next introduce our recent works on deep learning models for cancer subtyping based on histopathological images and radiological scans. These medical imaging data is widely available in the clinic, hence more suitable for the translation of cancer subtyping into real clinical practice to advance precision oncology.

Title: A Generalized Label-efficient Framework for Medical Image Segmentation and a new Benchmark for Colorectal Cancer Segmentation

Abstract: Medical image segmentation plays a crucial role in clinical settings, augmenting the accuracy of diagnosis, treatment planning, and disease surveillance. Here we present a generalized weakly supervised framework for medical image segmentation, termed WeakMed, to alleviate the reliance on costly annotations while being tractable to various scenarios. Specifically, the proposed WeakMed method creatively utilizes the mask-to-box transformation to overcome rectangular shape biases inherent in bounding box labels by leveraging economical bounding box annotations, thus largely streamlining the annotation of medical data. Besides, WeakMed is a versatile model, enabling adaptation to a variety of segmentation tasks and bringing no computation costs to model inference. Through rigorous evaluation across 9 segmentation tasks, 10 diverse medical datasets, and 6 distinct imaging modalities, WeakMed demonstrates superior accuracy and robustness when compared to its fully/weakly supervised counterparts. By alleviating the data annotation burden associated with a broad spectrum of segmentation tasks, WeakMed has the potential to advance diagnostic accuracy and facilitate the development of personalized treatment strategies. Besides, we collected and annotated the first benchmark dataset that covers diverse ERUS scenarios, i.e. colorectal cancer segmentation, detection, and infiltration depth staging. Our ERUS-10K dataset comprises 77 videos and 10,000 high-resolution annotated frames.
