Description: LIR task may be solved in many different ways. We chose to approach this task as object detection. This means that we treated each field in the document as an object. For grouping of line items, we added class line_item that indicates all fields that should be grouped together. As the detection model was used YOLOv8X. The model is based on the convolutional neural network. One of the advantages of this model is its speed and small size. We also incorporated methods used in [1].
