This paper concerns the detection of material discontinuity and inclusions in self-excited acoustic aluminium systems through the application of artificial intelligence methods. Classical machine learning techniques and convolutional neural networks were employed to tackle the binary classification problem associated with inclusion detection. The process shown involves the partitioning of base signals into samples for machine learning, followed by spectral analysis. Various feature extraction methods were compared, including Mel-Frequency Cepstral Coefficients (MFCC), short-time Fourier transform, Power Spectral Density (PSD) as well as wavelet transform. The study evaluates the efficacy of each method in capturing essential information for inclusion detection within the acoustic signals. Additionally, Principal Component Analysis (PCA) was employed to reduce dimensionality, and its impact on classifier performance was thoroughly analysed. The results of this research provide insights into the effectiveness of different neural network architectures and feature extraction techniques for the task of inclusion detection in self-excited acoustic cast aluminium systems. The findings contribute to the advancement of techniques for enhancing the quality control for the production of such systems through robust and efficient detection mechanisms.

In this paper, we present an off-policy reinforcement learning (RL) method used to tune the optimal weights of a nonlinear model predictive control (NMPC) scheme. The objective is to find the optimal policy minimizing the closed-loop performance of point stabilization with obstacle avoidance control task. The parameterized NMPC scheme serves to approximate the optimal policy and update the parameters via compatible off-policy deterministic actor-critic with gradient Q-learning critic (COPDAC-GQ). While efficient, this algorithm requires a heavy computational complexity when combined with NMPC, as two optimal control problems have to be solved at each time instant. We therefore propose two different methods to reduce the real-time computational cost of the algorithm. First, a neural network is used to learn the subsequent stateaction features of the advantage function. Then, we propose to use the information delivered by the NMPC scheme to approximate the subsequent state-action features in the critic. Whichever method is used removes the need of a secondary NMPC, significantly improving the training speed. The results show that there is no difference between the original method and the proposed methods in terms of the learned policy and the controlperformance, whereas the real-time computational burden is almost halved with the proposed methods.

The efficiency and performance of neural network (NN) controllers present a significant challenge in the rapidly evolving landscape of real-time closed-loop controlsystems, such as those used in solar inverters. This paper introduces a novel approach that enhances training efficiency by combining adaptive dropout with parallel computing techniques, utilizing the Levenberg-Marquardt (LM) algorithm and Forward Accumulation Through Time (FATT). Unlike traditional dropout methods that apply a fixed dropout rate uniformly across all neurons, Adaptive Dropout dynamically adjusts the dropout rate based on each neuron's calculated importance and its stage in the training process. This allows for the protection of more critical neurons while regularizing less significant ones, thereby improving convergence speed and enhancing generalization in the neural networkcontroller. To further accelerate the training process, the Adaptive Dropout method is seamlessly integrated into a parallel computing architecture. This architecture employs multiple cores to compute Dynamic Programming (DP) costs and Jacobian matrices for various trajectories simultaneously. This approach not only harnesses the computational power of modern multi-core systems but also ensures efficient processing across all trajectories. The experimental results demonstrate that adaptive dropout with parallel computing provides improvements in training efficiency and overall performance than both no dropout and weight dropout control schemes.
