Integration of Raman Spectroscopy, On-Line Microscopic Imaging and Deep Learning-Based Image Analysis for Real-Time Monitoring of Cell Culture Process
Part 5: Perceptual IntelligenceInternational audienceTraditionally, condition monitoring of mammalian cell culture processes is based on sampling and off-line analysis, which is labour intensive, time consuming, and causes time delays. In this work, in situ microscope and on-line Raman spectroscopy are investigated for simultaneous measurement of multiple properties of the cell growth state and biochemical indices of suspended animal cells. The focus is on investigation of deep learning-based Mask R-CNN algorithm for image analysis. The model is trained by 184 images with 183,040 cells using data augmentation methods and transfer learning technique. Mask R-CNN segments the clustered cells more effectively than the conventional one combining edge detection, intensity thresholding, and advanced watershed method. The evolution of geometrical features of cells is further analyzed, including equivalent diameter, circularity, and aspect ratio. It demonstrates the great potential of deep learning in the analysis of on-line images for control of the cell culture process
Research on Object Detection for Intelligent Sensing of Navigation Mark in Yangtze River
Part 5: Perceptual IntelligenceInternational audienceThe maintenance and management of navigation marks are essential for ensuring the safety of transportation on the Yangtze River. Considering the current inspection and management approaches, this paper introduces an intelligent method for inspecting inland river navigation marks using Unmanned Aerial Vehicles (UAVs). The method enables real-time monitoring of navigation marks using UAV video inspection. A UAV data acquisition platform captures video images of these marks. We have developed the ED-YOLOv5s object detection algorithm to detect and classify navigation marks. Building on this, the system can automatically assess the light quality and status of navigation marks at night. The ED-YOLOv5s algorithm is an enhancement of the YOLOv5s model, incorporating the ECA mechanism and DFFN structure, which are based on the ResNet principle. This modification enhances the model’s capability for network feature fusion. Experimental results indicate improvements in navigation mark detection with the ED-YOLOv5s. Although precision decreased by 1.76% when compared to the YOLOv5s model, recall and [email protected] increased by 3.59% and 2.97%, respectively. The detection results for light quality state from video images of navigation marks at night accurately reflect actual conditions. We have developed an intelligent sensing scheme for navigation marks on the Yangtze River based on the improved model. This scheme has been implemented in the Yichang section of the Yangtze River, significantly reducing the cost of daily inspections, enhancing cruise monitoring effectiveness, facilitating intelligent maintenance decisions for navigation marks, and further ensuring the navigational safety of the Yangtze River
End-To-End Control of a Quadrotor Using Gaussian Ensemble Model-Based Reinforcement Learning
Part 1: Machine LearningInternational audienceIn recent years, the rapid development of deep reinforcement learning has provided a new way to solve the robot control problems. However, the low sample efficiency and slow convergence speed of deep reinforcement learning have become one of the obstacles when transitioning from simulation to the real world. In this paper, we propose a quadrotor control policy using Gaussian ensemble model-based reinforcement learning. Unlike traditional control methods, this method uses an actor-critic deep neural network which is updated with a reward function to achieve end-to-end control of the quadrotor by establishing a mapping between the quadrotor's states and motor control signals. Additionally, we improve sample efficiency by constructing an ensemble model following a Gaussian normal distribution, which differs from conventional model-free RL methods. The environment model is trained using data from the agent's interaction with the real environment and reduces the number of interactions with the real environment by generating simulated data. The approach is evaluated in the AirSim which is a high-fidelity visual and physical simulator. The results show that the proposed approach improves the sample efficiency, eliminates oscillations and steady error, and demonstrates robustness to external disturbances
A Framework of Reinforcement Learning for Truncated Lévy Flight Exploratory
Part 1: Machine LearningInternational audienceDeep reinforcement learning (DRL) still explores insufficiently when dealing complex tasks with high-dimensional and large state spaces. Therefore, developing better exploration strategies is still one of the important tasks in reinforcement learning. The paper introduces a new exploration strategy ATLF (Adjustment of Truncated Lévy Flight exploration framework, ATLF) which augments the existing exploration mode with Lévy flight, making action selection more stochastic to boost exploration. The ALTF framework is combined with discrete-space algorithm DQN and continuous space-algorithm SAC to handle reinforcement learning tasks. Compared with a variety of reinforcement learning algorithms on OpenAI gym environments such as MountainCar-v0 and Walker2d-v2, the result shows that our algorithm has better exploration ability than vanilla DQN or SAC, obtaining higher overall rewards, and is less likely to fall into local optimization, and is more stable. Additionally, the result shows that the ALTF is highly compatible with existing deep reinforcement learning algorithms

synple: A Platform for Privacy Preserving Synthetic Patient Data Generation
Part 3: Human-Centric Biomedical SystemsInternational audiencePatient data collection is often constrained by accessibility, privacy, and confidentiality issues in healthcare research. To overcome this problem, the generation of synthetic data has been proposed. Nevertheless, existing synthetic patient generators do not cover European populations, nor do they offer flexibility in the process of generating data and building a biographical profile. In this paper, we introduce synple, a tool for synthetic patient data generation that mirrors the demographic characteristics of Portugal and Spain while adhering to GDPR and HIPAA regulations. Our platform produces comprehensive patient profiles, including both biological and biographical details, life narratives, and facial images, facilitated through an intuitive web interface powered by advanced generation algorithms. Additionally, the platform incorporates a validation feature, enabling users to assess the quality and consistency of the generated synthetic data. We demonstrate our system’s potential for enhancing healthcare research and safeguarding patient privacy in the digital age
