This study developed an experimental–computational framework for predicting mean nozzle discharge, effective spray width, derived spray angle, and mean inter‐nozzle overlap from nozzle model, operating pressure, and spray height. Four hollow‐cone ceramic nozzle models were evaluated at five pressures (6.0–9.5 bar) and three heights (30–50 cm), producing 60 operating conditions tested in triplicate. The resulting 180 experimental runs were averaged into 60 condition‐level records for machine‐learning analysis. Mean nozzle discharge ranged from 0.98 to 2.03 L , effective spray width ranged from 34.75 to 71.50 cm, the maximum derived spray angle reached 96.77°, and mean inter‐nozzle overlap ranged from 34.00 to 71.67 cm across the investigated operating conditions. Extra Trees Regressor provided the best predictions for mean nozzle discharge (, RMSE = 49.25 mL , MAE = 37.99 mL ), effective spray width (, RMSE = 2.37 cm), and mean overlap (, RMSE = 3.13 cm). Support vector regression with a radial basis function kernel performed best for derived spray angle (, RMSE = 3.53°). Pressure increased discharge and lateral footprint, whereas increasing height widened the footprint but generally reduced the geometrically derived angle. The models provide rapid condition‐level estimates within the investigated experimental domain and may complement physical calibration. Their transfer to other nozzle families, moving platforms, field environments, or real‐time control requires additional validation.","摘要 现有机器学习在农业喷施中的应用主要集中在雾滴尺寸描述符、冠层覆盖率、沉积量或基于图像的喷雾检测方面，而同时从可控操作变量预测水力与几何喷雾响应的研究仍较为有限。本研究开发了一个实验-计算框架，用于根据喷嘴型号、操作压力和喷雾高度预测平均喷嘴流量、有效喷雾宽度、推导喷雾角度及平均喷嘴间重叠量。研究评估了四种空心锥陶瓷喷嘴型号，在五个压力水平（6.0–9.5 bar）和三个高度（30–50 cm）下进行测试，共产生60种操作条件，每种条件重复三次。由此得到的180次实验运行被平均为60条条件级记录，用于机器学习分析。在所研究的操作条件下，平均喷嘴流量范围为0.98至2.03 L，有效喷雾宽度范围为34.75至71.50 cm，最大推导喷雾角度达到96.77°，平均喷嘴间重叠量范围为34.00至71.67 cm。极端随机树回归器（Extra Trees Regressor）在预测平均喷嘴流量（，RMSE = 49.25 mL，MAE = 37.99 mL）、有效喷雾宽度（，RMSE = 2.37 cm）和平均重叠量（，RMSE = 3.13 cm）方面表现最佳。采用径向基函数核的支持向量回归（support vector regression with a radial basis function kernel）在推导喷雾角度预测中表现最优（，RMSE = 3.53°）。压力增加了流量和横向覆盖范围，而增加高度则拓宽了覆盖范围，但通常减小了几何推导角度。所建立的模型能够在所研究的实验域内提供快速的条件级估计，并可作为物理校准的补充手段。将其推广至其他喷嘴系列、移动平台、田间环境或实时控制仍需进一步验证。","Journal of Field Robotics","2026-09-07T00:00:00Z",71,{"impact":16,"substance":78,"depth":79,"authority":80,"freshness":81,"relevant":18,"comment":82},20,18,14,7,"论文提出预测喷雾分布与液压行为的机器学习框架，数据详实，对精准农业装备优化有参考价值。",[84],{"name":74,"url":71},[23,86,87,24],"机器学习","精准农业",{"code":89,"slug":90,"name":91,"path":92,"parent_code":93},"I2","agricultural-ai","农业AI与大模型","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-ai","I",[],{"status":96,"locked":13,"version":30,"method":31,"evidence":97},"classified",{"candidates":98,"agricultural_evidence":100},[99,105],{"code":35,"score":12,"supported":100,"title":101,"abstract":103,"tags":104},true,[102],"precision agriculture",[],[23,87],{"code":89,"score":106,"supported":100,"title":107,"abstract":108,"tags":109},4,[],[86],[86],[111,112],"智慧农业 机器学习 植保机械 精准农业","智慧农业 机器学习","智慧农业机器学习植保机械精准农业-1911","10.1002\u002Frob.70346",{"doi":114,"openalex_id":116,"authors":117,"venue":74,"cited_by_count":62,"oa_url":8,"card":132,"direction":136,"ingested_from":63},"W7211920463",[118,121,123,125,127,129],{"name":119,"orcid":120},"Abdallah Elshawadfy Elwakeel","https:\u002F\u002Forcid.org\u002F0000-0002-9360-051X",{"name":122,"orcid":8},"Abdallah Zein Elden",{"name":124,"orcid":8},"Saad Ahmed",{"name":126,"orcid":8},"L Nasrat",{"name":128,"orcid":8},"Mohammad S.

A classifier is modelled as a concept-rank operator whose singular values govern how much concept-level signal survives the projection from pixel space to class logits, and a collapse audit is defined as the ratio of retained concept-rank energy to total concept energy. Under a low-label regime, where concept annotations are scarce and the audit must be estimated from few labelled examples, the bound predicts that audit reliability degrades as a function of the concept-rank spectrum and the label budget. The analysis is a theoretical and methodological contribution: it derives the bound, states the conditions under which a collapse audit is identifiable, and characterises the operating characteristics of the audit as a decision procedure under a declared variance structure (between-cluster SD = 6.0, residual SD = 4.5, intraclass correlation = 0.64). Power was estimated across 2000 design cells for cluster counts of 8, 16, 24 and 32 and effect sizes of 3, 5 and 8 percentage points; 52 clusters were required for 5 percentage points at 80% power. The bound reframes concept audits as capacity tests rather than fidelity tests, with consequences for how smallholder fungicide-selectivity decisions should be supported by interpretable disease classifiers.","面向植物病害分类器的基于概念的可解释性方法，通常以其概念激活是否与人工标注标签相关作为评价标准，但该标准对一个更先前的问题保持沉默：分类器的内部表征是否保留了足够的概念秩结构，从而使任何审计具有信息量。本分析将该先前问题形式化为一个可解释性容量上界。分类器被建模为概念秩算子，其奇异值支配着从像素空间到类别logits的投影中概念级信号得以保留的程度，并将坍缩审计定义为保留的概念秩能量与总概念能量之比。在低标签情形下，概念标注稀缺且审计必须由少量标注样本估计，该上界预测审计可靠性会随概念秩谱和标签预算的函数而退化。本分析是一项理论和方法论贡献：推导出该上界，陈述坍缩审计可识别的条件，并在声明的方差结构（簇间SD = 6.0，残差SD = 4.5，组内相关系数 = 0.64）下刻画审计作为决策程序的操作特征。在2000个设计单元中，针对簇数为8、16、24和32以及效应量为3、5和8个百分点的情形估计了功效；在80%功效下达到5个百分点需要52个簇。该上界将概念审计重新框定为容量检验而非保真度检验，并对可解释病害分类器应如何支持小农杀菌剂选择性决策具有启示意义。","Zenodo (CERN European Organization for Nuclear Research)","2026-10-21T00:00:00Z",69,{"impact":149,"substance":150,"depth":79,"authority":16,"freshness":12,"relevant":18,"comment":151},8,21,"理论方法论文，提出可解释性容量上界并给出审计功效分析，对智慧农业病害识别可信度有参考价值，但属小众方法学研究、缺乏田间实证，暂不宜进入每日精选。",[153],{"name":145,"url":142},[23,155,156,157,158],"农业人工智能","小农户","植物病害识别","可解释性",{"code":160,"slug":161,"name":162,"path":163,"parent_code":164},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",[166],{"code":89,"slug":90,"name":91,"path":92,"parent_code":93},{"status":96,"locked":13,"version":30,"method":31,"evidence":168},{"candidates":169,"agricultural_evidence":100},[170,175,180],{"code":160,"score":16,"supported":100,"title":171,"abstract":173,"tags":174},[172],"smallholder",[172],[156],{"code":89,"score":12,"supported":100,"title":176,"abstract":178,"tags":179},[177],"computer vision",[],[155,157],{"code":35,"score":18,"supported":13,"title":181,"abstract":182,"tags":183},[],[],[23],[185,186],"农业人工智能 植物病害识别 可解释性 智慧农业","农业人工智能 植物病害识别","农业人工智能植物病害识别可解释性智慧农业-5592","10.5281\u002Fzenodo.23545193",{"doi":188,"openalex_id":190,"authors":191,"venue":145,"cited_by_count":62,"oa_url":142,"card":198,"direction":136,"ingested_from":63},"W7223137323",[192,194,196],{"name":193,"orcid":8},"Akshay Ramgoolam",{"name":195,"orcid":8},"Priya Bundhoo Appadoo",{"name":197,"orcid":8},"Jean-Noël LEspérance",{"tldr":199,"method":200,"finding":201,"direction":136,"opportunity":202},"提出可解释性容量上界，评估低标签下概念秩崩溃审计的可靠性。","将分类器建模为概念秩算子，推导容量上界并做2000格功效模拟。","审计可靠性随概念秩谱与标签预算下降；5个百分点效应需52个聚类达80%功效。","可将容量上界用于小农户杀菌剂选择性决策的可解释模型审计与标签预算设计。","2026-10-22T11:21:10.425290Z",{"id":205,"title":206,"url":207,"summary":208,"summary_zh":209,"content":8,"source_name":145,"source_url":207,"published_at":146,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":147,"score_detail":210,"sources":214,"tags":216,"primary_topic":220,"secondary_topics":226,"classification":228,"search_phrases":253,"slug":256,"view_count":62,"doi":257,"paper":258,"created_at":270},5591,"Hierarchical Conformal Risk Control for Artificial Intelligence Agriculture Irrigation Scheduling Under Unmodeled Infiltration: A Computer Safety-Guarantee Evaluation","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23543665","Irrigation scheduling algorithms that rely on soil-moisture forecasts are vulnerable to unmodeled infiltration, the process by which water bypasses the root zone through preferential pathways that resistance-based soil models cannot represent.

It defines a temporal-stability audit as a sequence of concept-probe accuracies measured across defined phenological windows, and it derives an interpretability decay bound: the rate at which probe accuracy can fall before the fungicide-timing decision it is meant to support becomes unreliable. The bound is expressed as a function of the probe's initial margin, the drift in concept prevalence between windows, and the classifier's sensitivity to the drifted features, and it yields a certified audit interval rather than a single-point certificate. The paper then characterises the operating characteristics of the audit design under a declared variance structure, using a replication-based evaluation of the before-after-control-impact estimator with between-cluster SD = 6.0, residual SD = 4.5 and intraclass correlation = 0.64.

The contribution is a decision-theoretic account of when a concept-probe certificate expires, and a design rule for scheduling re-audits across the season.","概念探针审计（concept-probe audit）日益被用于验证作物病害分类器的内部表征是否追踪小农户会据以采取行动的病理学概念，但在生长季某一时点获得认证的探针，可能随着物候变化改变田间的视觉统计特征而悄然与这些概念脱钩。本分析将这种脱钩视为一个形式化对象。它将时间稳定性审计（temporal-stability audit）定义为在既定物候窗口内测量的一系列概念探针准确率，并推导出一个可解释性衰减界限（interpretability decay bound）：即探针准确率在其所支持的杀菌剂施用时机决策变得不可靠之前所能下降的速率。该界限表示为探针初始裕度、窗口间概念流行率漂移以及分类器对漂移特征敏感度的函数，并给出一个经认证的审计区间而非单点认证。随后，本文在声明的方差结构下刻画该审计设计的运行特征，采用基于重复的前后对照影响估计量评估，其中组间标准差 = 6.0、残差标准差 = 4.5、组内相关系数 = 0.64。功效在 2000 个设计单元上估计，聚类数取 8、16、24 和 32，效应量取 3、5 和 8 个百分点；在 80% 功效下达到 5 个百分点需要 54 个聚类。本文的贡献在于从决策论角度阐明概念探针认证何时失效，并给出在整个生长季内安排重新审计的设计规则。",70,{"impact":149,"substance":211,"depth":79,"authority":16,"freshness":12,"relevant":18,"comment":279},"该论文提出概念探针审计的时序稳定性框架与可解释性衰减界，方法新颖、统计设计扎实，但属小众方法论研究，产业影响有限，适合作为专业精选而非头条。",[281],{"name":145,"url":274},[23,155,156,283,284],"作物病害识别","模型审计",{"code":160,"slug":161,"name":162,"path":163,"parent_code":164},[287],{"code":89,"slug":90,"name":91,"path":92,"parent_code":93},{"status":96,"locked":13,"version":30,"method":31,"evidence":289},{"candidates":290,"agricultural_evidence":100},[291,295,299],{"code":160,"score":17,"supported":100,"title":292,"abstract":293,"tags":294},[172],[156,172],[156],{"code":89,"score":12,"supported":100,"title":296,"abstract":297,"tags":298},[177],[],[283,155],{"code":35,"score":18,"supported":13,"title":300,"abstract":301,"tags":302},[],[],[23],[304,305],"概念探针 时序稳定性 作物病害分类器","杀菌剂 施药时机 可解释性衰减","概念探针时序稳定性作物病害分类器-5590","10.5281\u002Fzenodo.23545234",{"doi":307,"openalex_id":309,"authors":310,"venue":145,"cited_by_count":62,"oa_url":274,"card":317,"direction":136,"ingested_from":63},"W7223088030",[311,313,315],{"name":312,"orcid":8},"Abdi-Basid Idriss Farah",{"name":314,"orcid":8},"Amina Abdillahi Guedi",{"name":316,"orcid":8},"Moussa Omar Youssouf",{"tldr":318,"method":319,"finding":320,"direction":136,"opportunity":321},"提出概念探针时间稳定性审计与可解释性衰减界，判断何时需重新审计。","定义跨物候窗口探针精度序列，推导衰减界，用BACI复制评估统计功效。","5个百分点效应需54个聚类达80%功效，审计证书会随物候漂移过期。","可将衰减界与再审计调度规则嵌入小农户杀菌剂时机决策支持系统，并验证跨作物泛化。","2026-10-22T11:21:08.978348Z",{"id":324,"title":325,"url":326,"summary":327,"summary_zh":328,"content":8,"source_name":145,"source_url":326,"published_at":146,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":329,"score_detail":330,"sources":333,"tags":335,"primary_topic":338,"secondary_topics":339,"classification":340,"search_phrases":356,"slug":359,"view_count":62,"doi":360,"paper":361,"created_at":371},5589,"Conformal-Risk Evaluation for Artificial Intelligence Agriculture Spray-Nozzle Fault Detection Under Label-Delay Feedback: A Computer Coverage Audit","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23544107","Spray-nozzle fault detection in precision agriculture is a classification problem in which the label that confirms a fault arrives after the spray pass, so the detector must act on unlabelled evidence and its error rate must be certified before the label exists. Conformal prediction offers distribution-free coverage guarantees, but the guarantee is stated for exchangeable calibration and test data, an assumption that label-delayed feedback violates because the calibration set is always older than the deployment set. the present analysis formalises label-delay feedback as a distribution shift in the conformity score and derives a coverage bound for split-conformal fault detectors under that shift. The bound separates the nominal miscoverage rate into an exchangeable component and a delay-induced component that scales with the total variation distance between the calibration and deployment score distributions. A replication-based evaluation of the ['Intercept', 'exposure', 'group', 'severity'] estimator was conducted: 600 data sets of N = 500 were drawn from a declared data-generating process (intercept 12.0, exposure 0.42, group -3.1, severity 1.35, error SD 4.2), and the study characterises the behaviour of the ordinary least squares estimator under the stated process. The estimator recovered the declared coefficients with estimated bias 0.01122 for the intercept and -0.0002 for exposure, root mean squared error 0.9217 and 0.01614 respectively, and empirical coverage of the nominal 95% intervals of 1.0 for both parameters across 600 replications. The coverage audit shows that the delay-induced term, not the exchangeable term, dominates the risk of a conformal spray-nozzle detector, and that the audit procedure can certify a detector before field labels return.","在精准农业中，喷雾喷嘴故障检测是一个分类问题，其中确认故障的标签在喷雾作业结束后才到达，因此检测器必须基于未标记的证据采取行动，并且其错误率必须在标签存在之前得到认证。保形预测（conformal prediction）提供了无分布覆盖保证，但该保证是针对可交换的校准数据和测试数据而言的，而标签延迟反馈违反了这一假设，因为校准集总是比部署集更旧。本分析将标签延迟反馈形式化为一致性分数中的分布偏移，并推导了在该偏移下分裂保形故障检测器的覆盖界。该界将名义错误覆盖 rate 分解为可交换分量和延迟诱导分量，后者随校准与部署分数分布之间的全变差距离而缩放。对 ['Intercept', 'exposure', 'group', 'severity'] 估计器进行了基于重复的评估：从声明的数据生成过程（截距 12.0，暴露 0.42，分组 -3.1，严重程度 1.35，误差标准差 4.2）中抽取了 600 个 N = 500 的数据集，研究刻画了普通最小二乘估计器在所述过程下的行为。该估计器恢复了声明的系数，截距的估计偏差为 0.01122，暴露为 -0.0002，均方根误差分别为 0.9217 和 0.01614，两个参数在 600 次重复中名义 95% 区间的经验覆盖率为 1.0。覆盖审计表明，延迟诱导项而非可交换项主导了保形喷雾喷嘴检测器的风险，并且该审计程序可以在田间标签返回之前对检测器进行认证。",62,{"impact":149,"substance":79,"depth":331,"authority":212,"freshness":12,"relevant":18,"comment":332},17,"论文提出标签延迟下共形预测覆盖界，方法有新意但属预印本、应用面窄，可作为专业补充而非每日精选头条。",[334],{"name":145,"url":326},[23,155,336,337],"精准施药","病虫害监测",{"code":89,"slug":90,"name":91,"path":92,"parent_code":93},[],{"status":96,"locked":13,"version":30,"method":31,"evidence":341},{"candidates":342,"agricultural_evidence":100},[343,347,351],{"code":89,"score":212,"supported":100,"title":344,"abstract":345,"tags":346},[238],[],[155],{"code":35,"score":81,"supported":100,"title":348,"abstract":349,"tags":350},[],[87,102],[23],{"code":352,"score":18,"supported":13,"title":353,"abstract":354,"tags":355},"F4",[],[],[336],[357,358],"农业人工智能 病虫害监测 智慧农业 精准施药","农业人工智能 病虫害监测","农业人工智能病虫害监测智慧农业精准施药-5589","10.5281\u002Fzenodo.23544107",{"doi":360,"openalex_id":362,"authors":363,"venue":145,"cited_by_count":62,"oa_url":326,"card":366,"direction":136,"ingested_from":63},"W7223116087",[364],{"name":365,"orcid":8},"Achieng' Atim Okello",{"tldr":367,"method":368,"finding":369,"direction":136,"opportunity":370},"将标签延迟反馈建模为共形分数分布偏移，推导覆盖率界并审计喷雾喷嘴故障检测器。","分裂共形预测、总变差距离、600次重复模拟（N=500）评估OLS估计。","延迟诱导项而非可交换项主导检测器风险，审计可在田间标签返回前认证检测器。","可将该覆盖率审计框架扩展到其他标签延迟的农业传感器故障检测，并研究延迟分布估计误差对认证的影响。","2026-10-22T11:21:02.845718Z",{"id":373,"title":374,"url":375,"summary":376,"summary_zh":377,"content":8,"source_name":145,"source_url":375,"published_at":146,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":378,"score_detail":379,"sources":381,"tags":383,"primary_topic":387,"secondary_topics":388,"classification":389,"search_phrases":416,"slug":419,"view_count":62,"doi":420,"paper":421,"created_at":432},5588,"Certified Temporal Fusion of Artificial Intelligence Climate Analytics for Crop Failure Early Warning Under Sparse Agricultural Sensors: Error Bounds and Famine Relief Targeting","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23545489","Sparse agricultural sensor networks across sub-Saharan Africa leave crop-failure early-warning systems with too little ground observation to support reliable famine relief targeting.

Using NASA POWER monthly reanalysis for Accra, Ghana (2000-2023, 312 observations), the analysis establishes a mean temperature of 26.521 C and a warming trend of 0.1622 C per decade, which calibrates the climate-analytics prior. The derived bounds show that relief-targeting error scales with the square root of sensor density and with the Lipschitz constant of the crop-response function, yielding an explicit sensor-placement rule for a target misclassification rate.
