With the development of advanced information and intelligence technologies, precision agriculture has become an effective solution to monitor prevent crop pests diseases. However, pest disease recognition in applications is essentially fine-grained image classification task, which aims learn discriminative features that can identify subtle differences among similar visual samples. It still challenging solve for existing standard models troubled by oversized parameters low accuracy performance. Therefore, this paper, we propose a feature-enhanced attention neural network (Fe-Net) handle diseases innovative agronomy practices. This model established based on improved CSP-stage backbone network, offers massive channel-shuffled various dimensions sizes. Then, spatial module added exploit interrelationship between different semantic regions. Finally, proposed Fe-Net employs higher-order pooling mine more highly representative computing square root covariance matrix elements. The whole architecture efficiently trained end-to-end way without additional manipulation. comparative experiments CropDP-181 Dataset, achieves Top-1 Accuracy up 85.29% with average time only 71 ms, outperforming other methods. More experimental evidence demonstrates our approach obtains balance model’s performance parameters, suitable its practical deployment art applications.

Compared with mechanism-based modeling methods, data-driven based on big data has become a popular research field in recent years because of its applicability. However, it is not always better to have more when building forecasting model practical areas. Due the noise and conflict, redundancy, inconsistency time-series data, accuracy may reduce contrary. This paper proposes deep network by selecting understanding improve performance. Firstly, self-screening layer (DSSL) maximal information distance coefficient (MIDC) designed filter input high correlation low redundancy; then, variational Bayesian gated recurrent unit (VBGRU) used anti-noise ability robustness model. Beijing's air quality meteorological are conducted verification experiment 24 h PM2.5 concentration forecasting, proving that proposed superior other models accuracy.

Abstract This article deals with the problems of parameter estimation for feedback nonlinear controlled autoregressive systems (i.e., equation‐error systems). The bilinear‐in‐parameter identification model is formulated to describe system. An overall recursive least squares algorithm developed handle difficulty bilinear‐in‐parameter. For purpose avoiding heavy computational burden, an stochastic gradient deduced and forgetting factor introduced improve convergence rate. Furthermore, analysis proposed algorithms are established by means process theory. effectiveness illustrated simulation example.

Weather is an essential component of natural resources that affects agricultural production and plays a decisive role in deciding the type production, planting structure, crop quality, etc. In field agriculture, medium- long-term predictions temperature humidity are vital for guiding activities improving yield quality. However, existing intelligent models still have difficulties dealing with big weather data predicting applications, such as striking balance between prediction accuracy learning efficiency. Therefore, multi-head attention encoder-decoder neural network optimized via Bayesian inference strategy (BMAE-Net) proposed herein to predict time series changes accurately. Firstly, we incorporate into gated recurrent unit construct Bayesian-gated units (Bayesian-GRU) module. Then, mechanism introduced design structure each layer, applicability time-length changes. Subsequently, framework hyperparameter optimization designed infer intrinsic relationships among time-series high accuracy. For example, R-evaluation metrics three locations 0.9, 0.804, 0.892, respectively, while RMSE reduced 2.899, 3.011, 1.476, seen Case 1 data. Extensive experiments subsequently demonstrated BMAE-Net has overperformed on location datasets, which provides effective solution applications smart agriculture system.
