Abstract: Systems and methods herein present a multi-modal model, or insight miner, for agricultural use. The model is used for generating actionable insights from time-series agricultural data. To do so, a control system of a farming machine includes the insight miner and a training module. The miner ingests agricultural information (e.g., time series field measurements), identifies trends in the time-series data (e.g., increasing, decreasing, etc.), and determines potential farming actions to take based on identified trends. To do so, the model generates visual representations of the time-series data, inputs the visual representations into a model to obtain a natural language description of that data, and enact farming actions based on the insights obtained. The training module trains the model by generating visual representation and natural language pairs, which are used to train the model.
