Multi-agent reinforcement learning has emerged as a promising approach for the control of multi-robot systems. Nevertheless, the low sample efficiency of MARL poses a significant obstacle to its broader application in robotics. While data augmentation appears to be a straightforward solution for improving sample efficiency, it usually incurs training instability, making the sample efficiency worse. Moreover, manually choosing suitable augmentations for a variety of tasks is a tedious and time-consuming process. To mitigate these challenges, our research theoretically analyzes the implications of data augmentation on MARL algorithms. Guided by these insights, we present AdaptAUG, an adaptive framework designed to selectively identify beneficial data augmentations, thereby achieving superior sample efficiency and overall performance in multi-robot tasks. Extensive experiments in both simulated and real-world multi-robot scenarios validate the effectiveness of our proposed framework.

As power systems evolve into more intelligent, flexible, and interactive networks with a higher penetration of Renewable Energy Sources (RES) on the demand side, net load forecasting has become a cost-effective and essential technique for planning, stability, and reliability of modern power grids. This study explores both direct and indirect methodologies for short-term net load forecasting (STNLF) in distribution grids considering solar net-metering using deep learning (DL) and machinelearning (ML) techniques. The proposed models begin with feature engineering and filtering using Pearson Correlation and Mutual Information (MI) indices, followed by developing a forecasting models employing a Bayesian Optimized Long Short-Term Memory (BO-LSTM) network and Bayesian Optimized Random Forest (BO-RF). The model's effectiveness was validated using historical net load data from the Lahore Electric Supply Company (LESCO) spanning January 2022 to January 2024, as LESCO has the highest number of net-metering customers among all Distribution Companies (DISCOS) in Pakistan. Results demonstrate the BO-RF model's capability to deliver accurate and robust STNLF, achieving a Mean Absolute Percentage Error (MAPE) of 3.56% for the test data and 2.21% for the train data. This study also compares the efficiency of indirect and direct methods for STNLF, demonstrating that the indirect method generally performs better than direct method in distribution grids.

Diseases like Parkinson's affect a non-negligible percentage of elder people worldwide. Affected people life quality strictly depends on the disease progression and counteractions that medical doctors decide to apply, according to periodical clinical evaluations. The possibility to have continuous monitoring of people with the help of electronic devices is a desirable opportunity for two main reasons: i) to reduce queues for medical doctors for in-person clinical assessment, ii) provide them with real-time and continuous monitoring data produced by assisted people in their home environment. To this end, the paper proposes the development and physical realization of an all-in-one lowcost device, able to both measure and process movement data in real-time, adopting miniaturized inertial sensors and machinelearning capabilities. To accomplish the task, a pre-validated movement simulator is adopted to generate data concerning different kinds of movement disorders, specifically focusing on tremors related to Parkinson's disease specific medical tests. The simulator takes into consideration the metrological features of the platform later adopted in the miniaturized device. The generated data are then used to train a machinelearning tool to recognize such disorders and provide an estimation of the disease's progression status. Once completed the tuning procedure, the whole process has been transferred to the developed physical device and validation tests have been carried out to prove its suitability for the described purpose. Obtained performance (minimum 98.5% mean accuracy with the emulated data) and low-energy consumption (maximum 27 mWh) allow stating as such prototype can be a robust basis for the following engineering and release phases to create a wearable object. It can be helpful for medical doctors as assisting support for correct diagnosis and prompt intervention in case of sudden worsening of people disease status.
