Sustainable Irrigation Requirement Prediction Using Internet of Things and Transfer Learning

Abstract

Irrigation systems are a crucial research area because it is essential to conserve fresh water and utilize it wisely. As a part of this study, the reliability of predicting the usage of water in the present and future is investigated in order to develop an effective prediction model to communicate demand. In order to improve prediction, we develop a prediction model and share the updated model with nearby farmers. In order to forecast the irrigation requirements, the recommended model utilizes the Internet of Things (IoT), k-nearest neighbours (KNN), cloud storage, long short-term memory (LSTM), and adaptive network fuzzy inference system (ANFIS) techniques. By collecting real-time environmental data, KNN identifies the closest water requirement from the roots and its surrounding. In order to predict short-term requirements, ANFIS is used. To transfer the new requirements for better prediction, transfer learning is used. Time-series-data updates are predicted using LSTM for future forecasting, and the integrated model is shared with other farmers using cloud environments to enhance forecasting and analysis. For implementation, a period of nine to ten months of data was collected from February to December 2021, and banana tree was used to implement the planned strategy. Four farms, with measurements, were considered at varying intervals to determine the minimum and maximum irrigation needs. The requirements of farms were collected over time and compared to the predictions. Future requirements at 8, 16, 24, 32, and 48 h were also anticipated. The results indicated were compared to manual water pouring, and, thus, the entire crop used less water, making our prediction model a real-world option for irrigation. The prediction model was evaluated using R2, MSLE and the average initial prediction value of R2 was 0.945. After using transfer learning, the prediction of the model of Farm-2, 3 and 4 were 0.951, 0.958 and 0.967, respectively.

Pavement Roughness Prediction Using Explainable and Supervised Machine Learning Technique for Long-Term Performance

“…A correlation analysis was conducted and the correlation coefficient between pavement age and cumulative traffic volume was found to be 0.57, indicating a moderate correlation between the two variables. A higher correlation between predictors can lead to inaccurate parameter estimation and large standard error [2,48]. This discussion on IRI prediction using regression analysis can be inaccurate if the predictor variables are dependent on each other, leading to violation of the regression analysis.…”

“…Introduced in 1951, the KNN rule is a distribution-free, statistical pattern classification method that has gained popularity since the 1960s due to the advancement of computational power [38]. The KNN algorithm compares a given testing tuple to a set of similar training tuples and learns by determining the class based on the K number of nearest neighbors [48]. Although statisticians have adopted KNN as a machine learning approach for 50 years, it is still widely used in pattern recognition and classification due to its unique features.…”
