However, the prediction of the fruit development stage is challenging, especially in sweet peppers, because the fruit harvest is discrete and its immature stage is indistinguishable. An ensemble model of convolutional and fully connected neural networks was developed to detect sweet pepper (Capsicum annuum L.) fruits in images and predict their development stages. The plants were grown in four rows in a greenhouse, and images were collected in each row. Plant growth and environmental data were collected every minute and month, respectively. For predicting the fruit stage, an ensemble of convolutional neural network (CNN) and multilayer perceptron (MLP) models were used. The fruit development stage was classified into immature, breaking, and mature stages with a CNN using images. Moreover, the immature stage was internally divided into four stages with an MLP. The plant growth and environmental data and the information from the CNN output were used for the MLP input. That is, a total of six stages were classified using the CNNโ€“MLP ensemble model. The ensemble model showed good agreement in predicting fruit development stages. The average accuracy of the six stages was F1 score = 0.77 and IoU = 0.86. The CNN-only model could classify the mature and breaking stages well, but the immature stages were not distinguished, while the MLP-only model could hardly classify the fruit stage except the immature stages. The most influential factors in classification were the data obtained from CNN and the plant growth and environment data, which contributed to the improvement of model accuracy. The ensemble models can help in appropriate labor allocation and strategic management by detecting individual fruits in images and predicting precise fruit development stages.์˜จ์‹ค์—์„œ๋Š” ๊ณ ๋ถ€๊ฐ€๊ฐ€์น˜์— ์—ด๋งค๋ฅผ ๋งบ๋Š” ์ž‘๋ฌผ์„ ํšจ์œจ์ ์œผ๋กœ ๊ด€๋ฆฌํ•˜๋Š” ๊ฒƒ์ด ์ค‘์š”ํ•˜๋‹ค. ๊ฐœ๋ณ„ ๊ณผ์‹ค์„ ๊ฐ์ง€ํ•˜๊ณ  ๊ทธ๊ฒƒ์˜ ๋ฐœ๋‹ฌ ๋‹จ๊ณ„๋ฅผ ์˜ˆ์ธกํ•จ์œผ๋กœ์จ ์žฌ๋ฐฐ์ž๊ฐ€ ๋…ธ๋™๋ ฅ์„ ์ ์žฌ์ ์†Œ์— ํ• ๋‹นํ•˜๊ณ , ์ „๋žต์ ์ธ ๊ด€๋ฆฌ๋ฅผ ํ•  ์ˆ˜ ์žˆ๋‹ค. ๊ทธ๋Ÿฌ๋‚˜ ํŒŒํ”„๋ฆฌ์นด์˜ ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„๋ฅผ ์˜ˆ์ธกํ•˜๋Š” ๊ฒƒ์€ ๊ณผ์‹ค ์ˆ˜ํ™•๋Ÿ‰์ด ๋ถˆ์—ฐ์†์ ์ด๊ณ , ๋ฏธ์„ฑ์ˆ™ ๋‹จ๊ณ„์—์„œ ๊ณผ์‹ค ๊ฐ„ ๋‚˜ํƒ€๋‚˜๋Š” ์™ธ๋ถ€์ ์ธ ํŠน์ง• ์ฐจ์ด๋ฅผ ๊ตฌ๋ณ„ํ•˜๊ธฐ ์–ด๋ ต๊ธฐ ๋•Œ๋ฌธ์— ์‰ฝ์ง€ ์•Š๋‹ค. ์ด ์—ฐ๊ตฌ์˜ ๋ชฉ์ ์€ ํ•ฉ์„ฑ๊ณฑ ์‹ ๊ฒฝ๋ง๊ณผ ์™„์ „ ์—ฐ๊ฒฐ ๊ณ„์ธต์˜ ์•™์ƒ๋ธ” ๋ชจ๋ธ์„ ์ด์šฉํ•˜์—ฌ ์ด๋ฏธ์ง€์—์„œ ํŒŒํ”„๋ฆฌ์นด ๊ณผ์‹ค์„ ์ฐพ์•„๋‚ด๊ณ  ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„๋ฅผ ์˜ˆ์ธกํ•˜๋Š” ๊ฒƒ์ด๋‹ค. ์‹คํ—˜์šฉ ์˜จ์‹ค์—์„œ ํŒŒํ”„๋ฆฌ์นด (Capsicum annuum L.)๋ฅผ 4์ค„๋กœ ์žฌ๋ฐฐํ•˜์˜€๊ณ , ๊ฐ ์ค„์— ์–‘๋ฉด์—์„œ ์‹๋ฌผ ์ด๋ฏธ์ง€๋ฅผ ์ˆ˜์ง‘ ํ•˜์˜€๋‹ค. 2020๋…„ 4์›” 6์ผ๋ถ€ํ„ฐ 6์›” 24์ผ๊นŒ์ง€ ํ™˜๊ฒฝ ๋ฐ์ดํ„ฐ๋Š” ๋ถ„ ๋งˆ๋‹ค, ์‹๋ฌผ ์ƒ์žฅ ๋ฐ์ดํ„ฐ๋Š” ์›” ๋งˆ๋‹ค ์ˆ˜์ง‘๋˜์—ˆ๋‹ค. ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„๋Š” ์ด๋ฏธ์ง€์—์„œ ํ•ฉ์„ฑ๊ณฑ ์‹ ๊ฒฝ๋ง์„ ์ด์šฉํ•˜์—ฌ ๋ฏธ์„ฑ์ˆ™, ๋ณ€ํ™” ์ค‘, ์„ฑ์ˆ™ 3 ๋‹จ๊ณ„๋กœ ๊ตฌ๋ถ„ํ•˜์˜€๊ณ , ๋ฏธ์„ฑ์ˆ™ ๋‹จ๊ณ„๋Š” ์™„์ „ ์—ฐ๊ฒฐ ๊ณ„์ธต์„ ์ด์šฉํ•˜์—ฌ ๋‹ค์‹œ ์„ธ๋ถ€์ ์œผ๋กœ 4 ๋‹จ๊ณ„๋กœ ๊ตฌ๋ถ„ ํ•˜์˜€๋‹ค. ํ™˜๊ฒฝ, ์‹๋ฌผ ์ƒ์žฅ ๋ฐ์ดํ„ฐ ๋ฐ ํ•ฉ์„ฑ๊ณฑ ์‹ ๊ฒฝ๋ง์˜ ์ถœ๋ ฅ ์ •๋ณด๊ฐ€ ์™„์ „ ์—ฐ๊ฒฐ ๊ณ„์ธต์— ์ž…๋ ฅ์œผ๋กœ ์‚ฌ์šฉ๋˜์—ˆ๋‹ค. ์ฆ‰, ์ด 6 ๊ฐœ์˜ ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„๊ฐ€ ์•™์ƒ๋ธ” ๋ชจ๋ธ์„ ์ด์šฉํ•˜์—ฌ ๋ถ„๋ฅ˜๋˜์—ˆ๋‹ค. ์•™์ƒ๋ธ” ๋ชจ๋ธ์€ ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„๋ฅผ ์˜ˆ์ธกํ•˜๋Š” ๋ฐ ์ข‹์€ ์„ฑ๋Šฅ์„ ๋ณด์˜€๋‹ค. ์ด 6 ๋‹จ๊ณ„์˜ ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„ ๋ถ„๋ฅ˜์— ํ‰๊ท  ์ •ํ™•๋„๋Š” F1 ์ ์ˆ˜ = 0.77, IoU = 0.86์ด๋‹ค. ํ•ฉ์„ฑ๊ณฑ ์‹ ๊ฒฝ๋ง๋งŒ์„ ์ด์šฉํ•œ ๋ชจ๋ธ์€ ์„ฑ์ˆ™ ๋‹จ๊ณ„์™€ ๋ณ€ํ™” ์ค‘ ๋‹จ๊ณ„๋ฅผ ์ž˜ ๋ถ„๋ฅ˜ ํ•  ์ˆ˜ ์žˆ์—ˆ์ง€๋งŒ ๋ฏธ์„ฑ์ˆ™ ๋‹จ๊ณ„๋ฅผ ๊ตฌ๋ณ„ํ•˜์ง€ ๋ชปํ•˜์˜€๋‹ค. ์™„์ „ ์—ฐ๊ฒฐ ๊ณ„์ธต๋งŒ์„ ์ด์šฉํ•œ ๋ชจ๋ธ์€ ๋ฏธ์„ฑ์ˆ™ ๋‹จ๊ณ„๋ฅผ ์ œ์™ธํ•˜๊ณ  ๊ณผ์‹ค ๋‹จ๊ณ„๋ฅผ ๊ฑฐ์˜ ๋ถ„๋ฅ˜ ํ•  ์ˆ˜ ์—†์—ˆ๋‹ค. ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„์˜ ๋ถ„๋ฅ˜์— ๊ฐ€์žฅ ํฐ ์˜ํ–ฅ์„ ๋ฏธ์น˜๋Š” ์š”์ธ์€ ํ•ฉ์„ฑ๊ณฑ ์‹ ๊ฒฝ๋ง์˜ ์ถœ๋ ฅ ์ •๋ณด์˜€๊ณ , ํ™˜๊ฒฝ ๋ฐ ์‹๋ฌผ ์ƒ์žฅ ๋ฐ์ดํ„ฐ๋Š” ๋ชจ๋ธ ์ •ํ™•๋„ ํ–ฅ์ƒ์— ๊ธฐ์—ฌํ–ˆ๋‹ค. ๋ณธ ์—ฐ๊ตฌ ๊ฒฐ๊ณผ๋Š” ์ถ”ํ›„ ๋‹ค์–‘ํ•œ ํ™˜๊ฒฝ์— ์ด๋ฏธ์ง€์—์„œ ๊ฐœ๋ณ„ ๊ณผ์‹ค์„ ์ฐพ์•„๋‚ด๊ณ , ์ •ํ™•ํ•œ ๊ณผ์‹ค ๋ฐœ๋‹ฌ ๋‹จ๊ณ„๋ฅผ ์˜ˆ์ธกํ•จ์œผ๋กœ์จ ์ ์ ˆํ•œ ๋…ธ๋™๋ ฅ ํ• ๋‹น ๋ฐ ์ „๋žต์  ๊ด€๋ฆฌ์— ๋„์›€์ด ๋  ์ˆ˜ ์žˆ์„ ๊ฒƒ์œผ๋กœ ์‚ฌ๋ฃŒ๋œ๋‹ค.ABSTRACT i CONTENTS iii LIST OF TABLES iv LIST OF FIGURES v INTRODUCTION 1 LITERATURE REVIEW 4 MATERIALS AND METHODS 9 RESULTS 24 DISCUSSION 34 CONCLUSION 39 LITERATURE CITED 40 ABSTRACT IN KOREAN 47Maste

    A logarithmically amortising temperature effect for supervised learning of wheat solar disinfestation of rice weevil Sitophilus oryzae (Coleoptera: Curculionidae) using plastic bags

    This work investigates the effectiveness of solar heating using clear polyethylene bags against rice weevil Sitophilus oryzae (L.), which is one of the most destructive insect pests against many strategic grains such as wheat. In this paper, we aim at finding the key parameters that affect the control heating system against stored grain insects while ensuring that the wheat grain quality is maintained. We provide a new benchmark dataset, where the experimental and environmental data was collected based on fieldwork during the summer in Canada. We measure the effectiveness of the solution using a novel formula to describe the amortising temperature effect on rice weevil. We adopted different machine learning models to predict the effectiveness of our solution in reaching a lethal heating condition for insect pests, and hence measure the importance of the parameters. The performance of our machine learning models has been validated using a 10-fold cross-validation, showing a high accuracy of 99.5% with 99.01% recall, 100% precision and 99.5% F1-Score obtained by the Random Forest model. Our experimental study on machine learning with SHAP values as an eXplainable post-hoc model provides the best environmental conditions and parameters that have a significant effect on the disinfestation of rice weevils. Our findings suggest that there is an optimal medium-sized grain amount when using solar bags for thermal insect disinfestation under high ambient temperatures. Machine learning provides us with a versatile model for predicting the lethal temperatures that are most effective for eliminating stored grain insects inside clear plastic bags. Using this powerful technology, we can gain valuable information on the optimal conditions to eliminate these pests. Our model allows us to predict whether a certain combination of parameters will be effective in the treatment of insects using thermal control. We make our dataset publicly available under a Creative Commons Licence to encourage researchers to use it as a benchmark for their studies

As a simplifying tool, crop modeling is a process of abstracting and interpreting agricultural phenomena. Understanding based on this interpretation can play a role in supporting academic and social decisions in agriculture. Process-based crop models have solved the challenges for decades to enhance the productivity and quality of crop production; the remaining objectives have led to demand for crop models handling multidirectional analyses with multidimensional information. As a possible milestone to satisfy this goal, deep learning algorithms have been introduced to the complicated tasks in agriculture. However, the algorithms could not replace existing crop models because of the research fragmentation and low accessibility of the crop models. This study established a developmental protocol for a process-based crop model with deep learning methodology. Literature Review introduced deep learning and crop modeling, and it explained the reasons for the necessity of this protocol despite numerous deep learning applications for agriculture. Base studies were conducted with several greenhouse data in Chapters 1 and 2: transfer learning and U-Net structure were utilized to construct an infrastructure for the deep learning application; HyperOpt, a Bayesian optimization method, was tested to calibrate crop models to compare the existing crop models with the developed model. Finally, the process-based crop model with full deep neural networks, DeepCrop, was developed with an attention mechanism and multitask decoders for hydroponic sweet peppers (Capsicum annuum var. annuum) in Chapter 3. The methodology for data integrity showed adequate accuracy, so it was applied to the data in all chapters. HyperOpt was able to calibrate food and feed crop models for sweet peppers. Therefore, the compared models in the final chapter were optimized using HyperOpt. DeepCrop was trained to simulate several growth factors with environment data. The trained DeepCrop was evaluated with unseen data, and it showed the highest modeling efficiency (=0.76) and the lowest normalized root mean squared error (=0.18) than the compared models. With the high adaptability of DeepCrop, it can be used for studies on various scales and purposes. Since all methods adequately solved the given tasks and underlay the DeepCrop development, the established protocol can be a high throughput for enhancing accessibility of crop models, resulting in unifying crop modeling studies.๋†์—… ์‹œ์Šคํ…œ์—์„œ ๋ฐœ์ƒํ•˜๋Š” ๋ฌธ์ œ๋“ค์€ ์ž‘๋ฌผ๊ณผ ํ™˜๊ฒฝ์˜ ์ƒํ˜ธ์ž‘์šฉ ํ•˜์— ๋ณต์žกํ•˜๊ฒŒ ์–ฝํ˜€ ์žˆ๋‹ค. ์ž‘๋ฌผ ๋ชจ๋ธ๋ง์€ ๋Œ€์ƒ์„ ๋‹จ์ˆœํ™”ํ•˜๋Š” ๋ฐฉ๋ฒ•์œผ๋กœ์จ, ๋†์—…์—์„œ ์ผ์–ด๋‚˜๋Š” ํ˜„์ƒ์„ ์ถ”์ƒํ™”ํ•˜๊ณ  ํ•ด์„ํ•˜๋Š” ๊ณผ์ •์ด๋‹ค. ๋ชจ๋ธ๋ง์„ ํ†ตํ•ด ๋Œ€์ƒ์„ ์ดํ•ดํ•˜๋Š” ๊ฒƒ์€ ๋†์—… ๋ถ„์•ผ์˜ ํ•™์ˆ ์  ๋ฐ ์‚ฌํšŒ์  ๊ฒฐ์ •์„ ์ง€์›ํ•  ์ˆ˜ ์žˆ๋‹ค. ์ง€๋‚œ ์ˆ˜๋…„ ๊ฐ„ ์ ˆ์ฐจ ๊ธฐ๋ฐ˜ ์ž‘๋ฌผ ๋ชจ๋ธ์€ ๋†์—…์˜ ๋ฌธ์ œ๋“ค์„ ํ•ด๊ฒฐํ•˜์—ฌ ์ž‘๋ฌผ ์ƒ์‚ฐ์„ฑ ๋ฐ ํ’ˆ์งˆ์„ ์ฆ์ง„์‹œ์ผฐ์œผ๋ฉฐ, ํ˜„์žฌ ์ž‘๋ฌผ ๋ชจ๋ธ๋ง์— ๋‚จ์•„์žˆ๋Š” ๊ณผ์ œ๋“ค์€ ๋‹ค์ฐจ์› ์ •๋ณด๋ฅผ ๋‹ค๋ฐฉํ–ฅ์—์„œ ๋ถ„์„ํ•  ์ˆ˜ ์žˆ๋Š” ์ž‘๋ฌผ ๋ชจ๋ธ์„ ํ•„์š”๋กœ ํ•˜๊ฒŒ ๋˜์—ˆ๋‹ค. ์ด๋ฅผ ๋งŒ์กฑ์‹œํ‚ฌ ์ˆ˜ ์žˆ๋Š” ์ง€์นจ์œผ๋กœ์จ, ๋ณต์žกํ•œ ๋†์—…์  ๊ณผ์ œ๋“ค์„ ๋ชฉํ‘œ๋กœ ๋”ฅ๋Ÿฌ๋‹ ์•Œ๊ณ ๋ฆฌ์ฆ˜์ด ๋„์ž…๋˜์—ˆ๋‹ค. ๊ทธ๋Ÿฌ๋‚˜, ์ด ์•Œ๊ณ ๋ฆฌ์ฆ˜๋“ค์€ ๋‚ฎ์€ ๋ฐ์ดํ„ฐ ์™„๊ฒฐ์„ฑ ๋ฐ ๋†’์€ ์—ฐ๊ตฌ ๋‹ค์–‘์„ฑ ๋•Œ๋ฌธ์— ๊ธฐ์กด์˜ ์ž‘๋ฌผ ๋ชจ๋ธ๋“ค์„ ๋Œ€์ฒดํ•˜์ง€๋Š” ๋ชปํ–ˆ๋‹ค. ๋ณธ ์—ฐ๊ตฌ์—์„œ๋Š” ๋”ฅ๋Ÿฌ๋‹ ๋ฐฉ๋ฒ•๋ก ์„ ์ด์šฉํ•˜์—ฌ ์ ˆ์ฐจ ๊ธฐ๋ฐ˜ ์ž‘๋ฌผ ๋ชจ๋ธ์„ ๊ตฌ์ถ•ํ•˜๋Š” ๊ฐœ๋ฐœ ํ”„๋กœํ† ์ฝœ์„ ํ™•๋ฆฝํ•˜์˜€๋‹ค.
