Using a text mining approach, including systematic preprocessing, bigram extraction, and term frequency-inverse document frequency (TF-IDF) based term weighting, the extracted competencies were categorized into knowledge, skill, and behavioral based competencies. Findings of the study reveal strong emphasis by employers on marketing research, marketing management, and sales management as core knowledge-based competencies required. While selling ability, client relationship management, and digital marketing have evolved as key skill-based competencies. Time management, teamwork, and leadership evolved as critical behavioral attributes needed for an MBA graduate specializing in the marketing domain. These insights highlight the need for management curricula to integrate conceptual learning with practical skill development and structured behavioral guidance. The results also provide accreditation bodies with evidence-based competency trends for strengthening outcome-based frameworks and guiding industry partners in aligning recruitment, training, and academic collaboration efforts.

To address these limitations, we present a stable edge-aware GAN architecture featuring two key innovations: dynamically learnable bilateral kernels that adaptively enhance structural gradients during training, and a layered generator with interpolated skip connections to maintain spatial coherence. Our methodology leverages adversarial training with Wasserstein regularization on the CT Kidney Dataset (12,446 images), optimizing for both global fidelity and local precision. Comprehensive experiments demonstrate the model's superiority through quantitative metrics—achieving a 43% improvement in Fréchet Inception Distance (FID = 87 vs. DCGAN's 149, <i>p</i> < 0.01), 16% higher edge sharpness (Sobel gradient magnitude 45.2 ± 3.1 vs. 38.9 ± 4.2), and 0.82 ± 0.05 SSIM scores. Clinical validation by board-certified radiologists confirmed 89% diagnostic plausibility for synthetic images, with particular praise for tumor boundary delineation. The architecture also shows exceptional training stability, reducing loss fluctuations by 34% compared to conventional GANs while efficiently scaling to 128 × 128 resolution. These results establish a new benchmark for privacy-preserving medical data augmentation, offering immediate value for scenarios with limited annotated datasets.

In this study, we introduce a novel hybrid framework that integrates metaheuristic feature-selection algorithms with an enhanced transformer-based prediction model fine-tuned using temporal embedding and adaptive attention pruning. We evaluate and compare the effectiveness of three nature-inspired metaheuristic algorithms: bat algorithm (BAT), gray wolf optimization (GWO), and beluga whale optimization (BWO) for selecting the most informative features from a time-series stock dataset. After feature selection, the optimal subsets are fed into our modified transformer equipped with temporal embeddings and adaptive attention pruning. Extensive experiments conducted on the Bharat Heavy Electricals Limited (BHEL) dataset show that the proposed hybrid framework outperforms traditional methods in terms of predictive accuracy. Among the evaluated approaches, the combination of BWO and the fine-tuned transformer achieves the best performance, yielding a Test RMSE of 0.0030 and a Test MAPE of 0.0108, demonstrating the superiority of BWO in identifying relevant features.

Key AI applications identified include predictive maintenance, anomaly detection, real-time monitoring, autonomous process control, and smart supply chains. Adoption is facilitated by external enablers 5G infrastructure, regulatory support, and internal factors, organizational readiness, and workforce skills. Challenges include data quality issues, cybersecurity risks, legacy system integration, and limited model scalability.

However, there are limitations to these approaches that prevent them from being deployed onto real-world hardware. Trained RL policies will often have limited transferability across even small changes to the environment setup. Instability during training can prevent optimal learning, a problem that only increases as the environment scales and grows in complexity. This work looks at addressing these limitations with a zero-shot transfer approach based on multi-agent RL. This is achieved by partitioning the task into smaller network machine subtasks, where agents learn the solution to the local problem. These local agents are independent of the network scale and can therefore be transferred to larger networks by mapping the agents to machines in the new network. Initial experiments show that this transfer method is effective for direct application to a number of ACD tasks. It is also shown that its performance is robust to changes in network activity, attack scenario and reduces the effects of network scale on performance.</p>","PeriodicalId":72253,"journal":{"name":"Applied AI letters","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ail2.70015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145846061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meta-learning for RL aims to improve the sample efficiency of training agents by encoding pre-training information that assists fast adaptation. This work focuses on two key meta-learning approaches, MAML and ML3, representing differing approaches to encoding meta learning knowledge. Both approaches are limited to sets of environments that use the same action and observation space. To overcome this, we also present an extension to ML3, Gen ML3, that removes this requirement by training the learned loss on the reward information only.
