Master thesis proposal: Deep learning for detection of coffee berry disease

Climate change brings along problems for farmers around the world. Assisting agriculture using AI to make farming more resilient may become an important step towards adapting to the new normal. Limiting the uncertainties and risks in food production can substantially improve the situation for many farmers, and increases the availability and robustness of food supplies. Deep learning is one of the most important tools in the AI toolbox, and has shown impressive results on many tasks on data of different modalities, not the least for computer vision.

Coffee berry disease (CBD) affects Arabica coffee plants, and is caused by the fungus Colletotrichum kahawae. CBD is one major factor hindering coffee production on the African continent. The spread of CBD is highly dependent on rainfall, temperature, and humidity, and has been affected by climate change.

In this master thesis, you will develop and train predictive models for detecting coffee berry disease using computer vision and deep learning. The work will include training models using images of infected and uninfected plants and berries. Techniques will include convolutional neural networks, transfer learning, domain adaptation, and few-shot learning. You will work in close collaboration with our deep learning research group and experts in agriculture from Mpendakazi Agribusiness in Tanzania. The work requires students with an excellent skill set within machine learning, image processing, and statistical inference. You will be expected to start out with a literature study, and then start with simpler models and eventually extend or develop upon more advanced solutions. As this is a master thesis project with a research organization, we will help you reach a high level of research excellence, and a successful project may result in writing a joint research paper in addition to the master thesis.
