Integrating vision-based technologies into distributed sensor domains offers unprecedented potential for data collection. However, it raises privacy concerns over the incredible amount of extra information inadvertently carried by the video stream. On the other hand, the advent of tiny machinelearning models running on edge devices with embedded GPUs/TPUs is revolutionizing computer vision and real-time tracking systems, enabling the local execution of computationally demanding tasks traditionally performed in the cloud. This study focuses on developing and characterizing vision-based virtual sensors capable of processing data from a local camera source to provide real-time measures of relevant metrics without storing or transmitting any video stream. The main advantages of vision-based virtual sensors running on the edge are data protection, reduced communication cost, and reduced detection latency. In addition, we propose a dynamic inference power manager (DIPM), based on adaptive frame rate, that allows us to explore the trade-off between power consumption and accuracy. Experimental results conducted on a real hardware platform show that the proposed virtual sensor, equipped with DIPM, can save up to 40% of the processing energy with a reduction of tracking accuracy lower than 10%, while retaining the privacy preservation benefits of virtual sensors.

The security of satellites has become critical in recent years due to their important role in modern society. However, numerous challenges, including limited computing resources, evolving cyber threats, and the isolated nature of satellites, hinder the development of effective security solutions. Different solutions should be implemented and combined to protect space assets: encryption, access control, zero-trust architecture, etc. This vision presents the challenges and aspects to consider for implementing an Intrusion Detection System (IDS) tailored to improve the security of satellite systems. Our approach uses a multi-level structure to define rule-based and machine-learning security approaches that address the challenges associated with different mission types. By strategically placing IDS components and considering the trade-offs of each location, we improve detection reliability. Additionally, we present an ontology-based method for visualizing the IDS configuration, which provides clear insight into system capabilities, enhances situational awareness, and facilitates identification and response to potential threats. We also provide strategies for updating the IDS while maintaining efficiency and security. This vision helps improve the cybersecurity measures of satellite operations and increase their resilience to cyberattacks.

Second-order information is valuable for many applications but challenging to compute. Several works focus on computing or approximating Hessian diagonals, but even this simplification introduces significant additional costs compared to computing a gradient. In the absence of efficient exact computation schemes for Hessian diagonals, we revisit an early approximation scheme proposed by Becker and LeCun (1989, BL89), which has a cost similar to gradients and appears to have been overlooked by the community. We introduce HesScale, an improvement over BL89, which adds negligible extra computation. On small networks, we find that this improvement is of higher quality than all alternatives, even those with theoretical guarantees, such as unbiasedness, while being much cheaper to compute. We use this insight in reinforcement learning problems where small networks are used and demonstrate HesScale in second-order optimization and scaling the step-size parameter. In our experiments, HesScale optimizes faster than existing methods and improves stability through step-size scaling. These findings are promising for scaling second-order methods in larger models in the future. Copyright 2024 by the author(s)

When using artificial intelligence systems for processing medical images, a large amount of software libraries, data and cloud computing is required. Implementing deep learning elements in CAD is a complex process and applying DevOps can help speed up this process. The implementation of DevOps approaches in the field of machinelearning differs from the operations with standard programs;therefore the development of MLOps approaches to the implementation of deep learning elements for the analysis of biomedical images is an actual task. The developed pipeline allows scientists and specialists to use the findings in this article to launch projects based on machinelearning and focus on model development rather than the process of setting up the environment. This paper provides examples of improved MLOps pipelines that can be used for solving problems of automatic image segmentation and evaluating the quantitative characteristics of microobjects.
