Ecoation is an AgTech company that provides early detection of pests, diseases and deficiencies for growers to reduce economic damage, increase crop value and decrease production costs. Data Science and Machine Learning plays a core part of product development at Ecoation. We analyze data from tens of thousands of plants in greenhouses everyday to help us understand the differences in data patterns across plant states, and provide results to growers. In the talk, we will further describe common tasks for data scientists at Ecoation. We will also provide examples of problems and challenges we have worked on in machine learning, data engineering, and other areas.
