Remote sensing platforms, weather‐related datasets, and field‐management records provide information on crop development and environmental conditions throughout the growing season. In this context, predictive tasks such as crop yield prediction, irrigation requirement assessment, and nutrient demand estimation can be naturally formulated as Time Series Extrinsic Regression (TSER), a supervised learning task in which a continuous target is predicted from one or more time series. This paper presents TSER within the Smart Agriculture domain and investigates its applicability to field‐level crop yield prediction using multisource agricultural time series. The study adopts a field‐based temporal approach where Sentinel‐2 observations are processed to derive vegetation‐index time series, spatially aggregated at parcel level, and integrated with ERA5‐Land weather‐related variables and static vineyard attributes. Representative neural and non‐neural TSER methods are compared under temporal and spatial generalization scenarios. Results show that TSER provides a suitable supervised learning framework for crop yield prediction from heterogeneous agricultural time series. Conditional LSTM achieves the best overall performance under temporal generalization across vintages, while non‐neural methods remain competitive under spatial generalization to unseen vineyard blocks. These findings suggest that TSER can support field‐level predictive modeling in Smart Agriculture, with model choice depending on the target generalization setting, data availability, and operational constraints.","摘要 农业中时间数据的日益丰富为数据驱动的决策支持系统创造了新的机遇，旨在提高农业系统的效率、可持续性和适应性。遥感平台、气象相关数据集和田间管理记录提供了整个生长季作物发育和环境状况的信息。在此背景下，作物产量预测、灌溉需求评估和养分需求估算等预测任务可以自然地表述为时间序列外在回归（TSER），这是一种监督学习任务，即从一个或多个时间序列中预测连续目标变量。本文在智慧农业领域内介绍TSER，并研究其利用多源农业时间序列进行田块级作物产量预测的适用性。本研究采用基于田块的时间方法，对Sentinel-2观测数据进行处理以导出植被指数时间序列，在地块尺度上进行空间聚合，并与ERA5-Land气象相关变量及静态葡萄园属性相整合。在时间泛化和空间泛化情景下，比较了具有代表性的神经与非神经TSER方法。结果表明，TSER为从异质农业时间序列进行作物产量预测提供了一个合适的监督学习框架。条件LSTM在跨年份的时间泛化下取得了最佳整体性能，而非神经方法在向未见葡萄园地块的空间泛化下仍具有竞争力。这些发现表明，TSER能够支持智慧农业中的田块级预测建模，模型选择取决于目标泛化设置、数据可用性和操作约束。",null,"Quality and Reliability Engineering International","2026-09-22T00:00:00Z","论文",10,false,72,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},12,20,17,13,1,"将时间序列外在回归引入田块级产量预测，方法新颖、结论有对比依据，但属学术论文，产业影响有限。",[24],{"name":10,"url":6},[26,27,28,29,30],"智慧农业","农业人工智能","遥感","作物产量预测","时间序列",[32,33],"Sentinel-2 作物产量预测","TSER 智慧农业","Sentinel-2作物产量预测-3155",0,"10.1002\u002Fqre.70406",{"doi":36,"openalex_id":38,"authors":39,"venue":10,"cited_by_count":35,"oa_url":6,"card":52,"direction":58,"ingested_from":59},"W7213984793",[40,43,46,48,50],{"name":41,"orcid":42},"Amalia Vanacore","https:\u002F\u002Forcid.org\u002F0000-0002-0320-5541",{"name":44,"orcid":45},"Armando Ciardiello","https:\u002F\u002Forcid.org\u002F0009-0005-7272-9663",{"name":47,"orcid":9},"Gennaro Pio Auricchio",{"name":49,"orcid":9},"Luigi Uccello",{"name":51,"orcid":9},"Annalisa Izzo",{"tldr":53,"method":54,"finding":55,"direction":56,"opportunity":57},"将田块级作物产量预测建模为时间序列外回归，比较多源农业时间序列上的神经与非神经方法。","Sentinel-2植被指数、ERA5-Land气象与葡萄园静态属性，对比LST","条件LSTM在跨年份时间泛化最优，非神经方法在空间泛化到新地块时仍有竞争力。","农业遥感与作物表型","可探索多作物、多区域下TSER模型迁移性与不确定性量化，及与农事决策系统耦合。","智慧农业 \u002F 农业物联网","openalex","2026-09-22T23:30:10.381662Z",{"total":62,"page":21,"page_size":62,"items":63},6,[64,108,136,163,210,245],{"id":65,"title":66,"url":67,"summary":68,"summary_zh":69,"content":9,"source_name":70,"source_url":67,"published_at":71,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":72,"score_detail":73,"sources":79,"tags":81,"search_phrases":83,"slug":86,"view_count":35,"doi":87,"paper":88,"created_at":107},2160,"An Optimized Temporal Attention-based Deep Learning Framwork for Accurate Crop Yield Prediction from Multi-source Agricultural Data","https:\u002F\u002Fdoi.org\u002F10.18805\u002Fag.d-6558","Background: In precision agriculture, crop yield prediction is crucial for supporting effective management of crops, timely settlement of farmers crop insurances, food security planning and serve as decision tool for sustainable agricultural achievements. However, prediction of crop yield is difficult due to the complex interaction behavior among diverse conditions in weather, soil properties, multispectral remote sensing observations and the dynamics in crop growth. Despite existing AI techniques like machine learning and deep learning models outperformed in predicting crop yield, they are often not able to capture the temporal dependencies. Furthermore, determining optimal hyperparameters for model training remains a challenging task, significantly influencing prediction accuracy, model convergence and generalization performance. Methods: To overcome this, the present study aimed to predict the crop yield using temporal attention (TA) based Artificial bee colony (ABC) optimized Bi - LSTM model using multi source agricultural data. The proposed model learns the sequential and temporal dependencies from both past and future time steps simultaneously, from the historical weather variables, soil properties, remote sensing derived normalized difference vegetation indices (NDVI) and historical yield data. The ABC algorithm was employed to automatically optimize the model hyperparameters with minimum run time. Result: The model is trained using district wise rice yield records of Tamil Nadu, historical weather variables, Sentinel-2 derived NDVI and soil properties. The dataset collected for major rice growing districts from 1995 to 2025 (30 years). The model shows the superior performance over conventional methods like random forest, support vector regression, deep neural network, convolutional neural network, long short-term memory models with lesser root mean square error (RMSE = 298.01 kg ha-1) and higher coefficient of determination, R2 (81.76%). Also, the training time of TA - ABC - Bi-LSTM model is comparatively less than the comparative models because of ABC optimization algorithm tuned the best hyperparameters compared to traditional trial and error manual method.","背景：在精准农业中，作物产量预测对于支持有效的作物管理、农民作物保险的及时理赔、粮食安全规划以及作为实现可持续农业的决策工具至关重要。然而，由于天气、土壤属性、多光谱遥感观测等多种条件之间复杂的交互作用以及作物生长的动态变化，作物产量预测仍然困难。尽管现有的机器学习、深度学习等人工智能技术在作物产量预测方面表现优异，但往往无法捕捉时间依赖性。此外，确定模型训练的最优超参数仍是一项具有挑战性的任务，显著影响预测精度、模型收敛性和泛化性能。方法：为解决上述问题，本研究旨在利用基于时间注意力（TA）的人工蜂群（ABC）算法优化的双向长短期记忆（Bi-LSTM）模型，结合多源农业数据预测作物产量。所提出的模型能够同时从历史和未来时间步中学习序列和时间依赖关系，数据来源包括历史气象变量、土壤属性、遥感衍生的归一化植被指数（NDVI）以及历史产量数据。采用ABC算法以最短运行时间自动优化模型超参数。结果：该模型使用泰米尔纳德邦各地区的稻米产量记录、历史气象变量、Sentinel-2衍生的NDVI和土壤属性进行训练。数据集收集了1995年至2025年（30年）主要水稻种植区的数据。该模型相比随机森林、支持向量回归、深度神经网络、卷积神经网络、长短期记忆模型等传统方法表现出更优的性能，均方根误差更低（RMSE = 298.01 kg ha-1），决定系数R²更高（81.76%）。此外，TA-ABC-Bi-LSTM模型的训练时间相比对比模型更短，因为ABC优化算法相比传统的试错手动方法能够调优出最佳超参数。","Agricultural Science Digest - A Research Journal","2026-09-10T00:00:00Z",76,{"impact":74,"substance":75,"depth":76,"authority":17,"freshness":77,"relevant":21,"comment":78},16,21,18,9,"提出时序注意力结合人工蜂群优化的Bi-LSTM产量预测模型，基于30年多源数据取得较高精度，方法新颖且数据规模可观，对精准农业与农业保险决策有参考价值。",[80],{"name":70,"url":67},[26,27,82,28,29],"水稻",[84,85],"作物产量预测 农业人工智能 智慧农业 水稻","作物产量预测 农业人工智能","作物产量预测农业人工智能智慧农业水稻-2160","10.18805\u002Fag.d-6558",{"doi":87,"openalex_id":89,"authors":90,"venue":70,"cited_by_count":35,"oa_url":67,"card":101,"direction":56,"ingested_from":59},"W7212119230",[91,93,95,97,99],{"name":92,"orcid":9},"M.

While spatiotemporal fusion (STF) bridges this resolution trade-off by integrating complementary observations, its practical application remains constrained by the idealized ”clear-sky assumption”. This requirement often favors the selection of temporally distant cloud-free acquisitions over temporally closer but cloud-contaminated observations, potentially reducing the relevance of reference information. To address this limitation, we propose CloudSTF, a robust framework designed to achieve high-fidelity reconstruction by effectively exploiting partially occluded observations. Our approach employs a Mask-guided Multi-scale Swin Transformer (M 2 ST) encoder to capture cloud spatial patterns and suppress noise propagation during feature extraction. This is coupled with a Cross-temporal Memory-guided Fusion (CTMF) module that adaptively integrates temporal trends with textural details retrieved from a spatio-temporal memory bank. To validate this paradigm, we introduce the Global Cloud-shrouded Regions (GCR-STF) benchmark, a geographically distributed dataset comprising 24 representative agricultural and urban sites across six continents. Extensive experiments demonstrate that CloudSTF consistently outperforms state-of-the-art methods. Additional assessments across varying cloud densities and diverse landscapes further demonstrate the robustness and applicability of CloudSTF under realistic cloud-contaminated conditions. These results suggest that CloudSTF provides a reliable solution for continuous Earth monitoring in realistic, cloud-prone environments.

In addition, the framework generated high-resolution plant height maps for field-scale analysis of spatial growth variability.

An Attention Based Multimodal Deep Clustering Framework for Rice Health Assessment","https:\u002F\u002Fdoi.org\u002F10.22266\u002Fijies2026.1031.06","Rice is Indonesia's staple crop, yet its productivity has declined in recent years because pest and disease outbreaks remain difficult to detect at an early stage.Existing precision agriculture approaches commonly process Internet of Things (IoT) sensor data and remote sensing imagery independently and often rely on supervised learning, requiring large amounts of labeled data.Meanwhile, multispectral drone imagery producing the Normalized Difference Vegetation Index (NDVI) provides richer information on crop physiological conditions than RGB-based vegetation indices.This study proposes Agricultural Multimodal Attention Clustering (AgriMAC), an unsupervised framework that integrates UAV derived NDVI imagery, 7-in-1 IoT soil sensor measurements, and historical weather data from the Open-Meteo API for rice field condition monitoring.Each modality is encoded using a dedicated autoencoder and fused through an entropy-regularized attention mechanism before Deep Embedded Clustering is performed.To reduce the influence of crop growth stage, the IoT representation is residualized using growth-phase statistics estimated exclusively from the training fold, enabling the discovered clusters to represent within-phase agronomic conditions rather than crop age.Experiments conducted under a grouped leave-one-field-out protocol produced a Silhouette Score of 0.465 ± 0.048, a Davies Bouldin Index of 0.807 ± 0.036, and a Calinski Harabasz Index of 195 ± 27.The learned groups also showed low normalized mutual information with growth phase (0.079 ± 0.043) and near chance phase decodability (balanced accuracy = 0.554 ± 0.042), indicating that they are only weakly associated with crop growth stage.The learned attention weights identified IoT soil measurements (0.570 ± 0.024) as the dominant modality, while NDVI imagery (0.210 ± 0.014) and weather information (0.220 ± 0.014) provided complementary spatial and temporal context.Overall, AgriMAC provides an interpretable and leakage-aware framework for multimodal clustering of rice field conditions.Although its clustering performance is comparable to that of a capacity-matched IoT-only model, it additionally quantifies the contribution of each sensing modality through attention weights and explicitly mitigates the growth-phase confound, making it suitable for field level agronomic condition monitoring and spatial decision support in precision agriculture.","水稻是印度尼西亚的主要作物，但近年来其生产力有所下降，因为病虫害暴发在早期阶段仍难以检测。现有的精准农业方法通常独立处理物联网（IoT）传感器数据和遥感影像，且往往依赖监督学习，需要大量标注数据。与此同时，生成归一化植被指数（NDVI）的多光谱无人机影像比基于RGB的植被指数能提供更丰富的作物生理状况信息。本研究提出农业多模态注意力聚类（AgriMAC），这是一个无监督框架，整合了无人机获取的NDVI影像、七合一IoT土壤传感器测量数据以及来自Open-Meteo API的历史天气数据，用于稻田状况监测。每种模态均使用专用自编码器进行编码，并通过熵正则化注意力机制进行融合，随后执行深度嵌入聚类。为减少作物生长阶段的影响，IoT表征利用仅从训练折估计的生长阶段统计量进行残差化处理，使发现的聚类能够表征阶段内的农艺状况而非作物年龄。在分组留一田块协议下进行的实验产生了0.465 ± 0.048的轮廓系数、0.807 ± 0.036的Davies-Bouldin指数和195 ± 27的Calinski-Harabasz指数。学习到的分组还显示出与生长阶段的低归一化互信息（0.079 ± 0.043）以及接近随机的阶段可解码性（平衡准确率 = 0.554 ± 0.042），表明它们与作物生长阶段仅存在弱关联。学习到的注意力权重将IoT土壤测量（0.570 ± 0.024）识别为主导模态，而NDVI影像（0.210 ± 0.014）和天气信息（0.220 ± 0.014）则提供了互补的空间和时间背景。总体而言，AgriMAC为稻田状况的多模态聚类提供了一个可解释且感知数据泄漏的框架。尽管其聚类性能与容量匹配的仅IoT模型相当，但它还通过注意力权重量化了每种传感模态的贡献，并明确减轻了生长阶段混杂因素，使其适用于田块级农艺状况监测和精准农业中的空间决策支持。","International journal of
