There have been several research works proposing new Explainable AI (XAI) methods designed to generate model explanations having specific properties, or desiderata, such as fidelity, robustness, human-interpretability. However, are seldom evaluated based on their true practical impact decision-making tasks. Without that assessment, might be chosen that, in fact, hurt the overall performance of combined system ML + end-users. This study aims bridge this gap by XAI Test, an...
Although recurrent neural networks (RNNs) are state-of-the-art in numerous sequential decision-making tasks, there has been little research on explaining their predictions. In this work, we present TimeSHAP, a model-agnostic explainer that builds upon KernelSHAP and extends it to the domain. TimeSHAP computes feature-, timestep-, cell-level attributions. As sequences may be arbitrarily long, further propose pruning method is shown dramatically decrease both its computational cost variance of...
Wire-arc directed energy deposition (DED) is suitable for depositing large-scale metallic components at high rates. In order to further increase productivity and efficiency by reducing overall manufacturing time, higher rates are desired. However, the conventional gas metal arc (GMA) based wire-arc DED, characterised input, normally results in remelting reheating relatively rates, process deteriorating mechanical performance. this study, a novel DED with combination of GMA an external cold...
This research evaluated the valorization of pine cone residue as an efficient, low-cost, and eco-friendly biosorbent for removal Cr⁶⁺ from aqueous solutions. Pine cones were characterized by techniques Brunauer-Emmett-Teller (BET), Attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM). Firstly, experimental design was performed to optimize adsorption conditions, investigating influence three primary...
Cold wire gas metal arc (CWGMA) additive manufacturing (AM) is more productive and beneficial than the common electric processes currently used in (WAAM). Adding a non-energised to (GMA) system makes it possible overcome process limitation decouple energy input from material feed rate. Two novel control methods were proposed, namely, power travel speed control, which can keep required geometry accuracy WAAM through broad range of thermal conditions. The reinforcement area bead kept constant...
This paper presents a distributed dynamic object model that is aligned with the concept of design history in context problem solving activities. A proposed as an enabling feature for CAD (computer-aided design) allowing teams to work cooperatively, accessing and exchanging information at run time engineering environment. The architecture environment allows artefact properties be associated any relevant aspect process, including those related specification, but also organisation hierarchy,...
The paper addresses a model, framework, and an implemented system for supporting design activities where the use of case-based reasoning may reveal particular appropriateness. In proposed environment, special attention is given to synthesis solutions by means adaptation. A pragmatic combination number artificial intelligence (AI) techniques, considering (CBR) as framing concept, enables implementation that conveniently supports most designers’ cognitive needs. highway bridges was chosen...
