This review conducted a systematic search of the Scopus, IEEE Xplore, ScienceDirect, and SpringerLink databases for articles published between January 2023 and January 2026. It used keyword combinations like \"IoT and machine learning and agriculture\", \"crop recommendation\", \"plant disease detection\", and \"precision farming\". From the initial pool of articles found, 30 articles met the criteria for empirical methodology, quantitative performance reporting, and clear dataset descriptions. These were chosen for detailed analysis. It was discovered that the ensemble, as well as the traditional machine learning methods, such as Random Forest, Support Vector Machine (SVM), and Decision Trees, produce highly accurate predictions of the crop yields with an accuracy of 99.9%. Meanwhile, Convolutional Neural Networks (CNN) and ResNet-based deep learning models detect diseases with an accuracy above 98% while Gated Recurrent Units (GRU) and Long-Short Term Memory (LSTM) time-series models provide forecasts of weather conditions with an accuracy ranging from 94 to 98%, due to the complex nature of the environment dynamics. The application of IoT systems for precision agriculture produced a significant improvement in terms of resource utilization, resulting in 60-96% of water savings, 25% increased yield, and 36-38% reduced herbicide use. Although these advancements have been made, wider application is still hindered by high costs of implementation, lack of technological skills among farmers, data privacy concerns, issues of scalability within different agricultural settings, and consistent internet connection in rural areas. The current paper evaluates the use of IoT and ML in the agriculture sector from diverse data sources and studies to reveal the immense benefits offered by the two systems in enhancing farming activities.</p>","PeriodicalId":33315,"journal":{"name":"Frontiers in Artificial Intelligence","volume":"9 ","pages":"1878006"},"PeriodicalIF":6.7,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13661805/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149184359","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}

While many deep learning models reach impressive overall performance, most existing approaches treat segmentation and classification as separate tasks, leading to limited interaction between spatial lesion localization and semantic disease knowledge. This segregation results in a high variance prediction and would reduce the overall robustness of automated diagnostic systems. To mitigate this limitation, we proposed SkinNet-X: a unified multitask framework to reformulate the skin lesion segmentation and classification tasks jointly. We achieve this with a shared hierarchical feature representation to transfer knowledge between both tasks while introducing new Cross Task Consistency Learning (CTCL) strategy that enforces semantic consistency between lesion localization and disease prediction during joint optimization. In order to enhance the discriminative capability of feature expression and alleviate redundant representations, a dual stage multi label feature optimization module is further exploited, accompanied by an adaptive PolyLoss based optimization strategy stabilizing multitask learning. The effectiveness of the proposed SkinNet-X framework was evaluated using segmentation and classification experiments on the ISIC 2018, ISIC 2019, and HAM10000 benchmark datasets. We also performed additional analyses, namely ablation studies, computational complexity evaluation, sensitivity analysis and statistical validation to explore the contribution of each architectural component. Experimental results show that the proposed multitask learning strategy can consistently improve accuracy of lesion localization and performance of classification with robust generalizability across multiple datasets. These findings demonstrate that SkinNet-X is an effective and potentially useful framework for automated skin lesion analysis and computer-aided dermatological diagnosis.</p>","PeriodicalId":33315,"journal":{"name":"Frontiers in Artificial Intelligence","volume":"9 ","pages":"1886221"},"PeriodicalIF":6.7,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13662072/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149184666","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}

This paper proposes Prior-Enhanced Axial TransUNet (PEAT), which combines the broad medical representations of foundation models with task-specific discriminative learning. PEAT introduces three core components: Bottleneck Semantic Alignment (BSA) uses the frozen MedSAM image encoder as a training-stage feature reference and guides the semantic organization of the task network's bottleneck representation through an L1 alignment constraint; Dual-path Attention-enhanced Fusion (DAF) adaptively fuses CNN local features with MaxViT global contextual features by cascading coordinate attention and SENetV2; and Bi-granular Region-Aware Attention (BRA) achieves efficient non-local context modeling through Top-<i>k</i> window routing and patch-level sparse interaction. The MedSAM branch participates only during training, and only the task-specific network runs at inference. Under a setting in which all compared methods adopt the same preprocessing and evaluation protocol, PEAT achieves kidney and tumor Dice scores of 97.69% and 91.83% on KiTS21 and 96.80% and 92.58% on KiTS23, respectively. Across all four tasks, PEAT attains the highest Dice among the compared methods; ablation studies further show that the progressive integration of BSA, DAF, and BRA yields consistent gains, with the complete model outperforming all single and pairwise configurations.

Drawing on Peirce's concepts of semiosis, abduction, inquiry, fallibilism, pragmaticism, and the community of inquiry, the framework distinguishes between computational processes performed by AI systems and the human and institutional practices through which their outputs acquire epistemic and practical significance. AI outputs may function as signs and may generate hypotheses that are functionally analogous to abductive possibilities; however, interpretation, evidential assessment, justification, ethical judgment, and responsibility remain situated within human communities of inquiry. The framework further translates Peircean concepts into practical principles for XAI, including contextual interpretation, uncertainty communication, contestability, human review, stakeholder participation, evidence-based revision, and continuous evaluation. A worked example involving generative AI illustrates how an AI-generated explanation can move through interpretation, questioning, evidence checking, contestation, and revision rather than being accepted as a final epistemic product. The article therefore positions Peircean pragmatism not as a replacement for technical XAI methods but as a philosophical and normative framework that complements them by clarifying the epistemological conditions of meaningful explanation, trustworthy human oversight, and responsible AI governance.</p>","PeriodicalId":33315,"journal":{"name":"Frontiers in Artificial Intelligence","volume":"9 ","pages":"1962744"},"PeriodicalIF":6.7,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13658564/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149184927","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}
