The Rey-Osterrieth Complex Figure Test (ROCFT) is a widely used neuropsychological tool for assessing the presence and severity of different diseases. It involves presenting a complex illustration to the patient who is asked to copy it, followed by recall from memory after 3 and 30 min. In clinical practice, a human rater evaluates each component of the reproduction, with the overall score indicating illness severity. However, this method is both time-consuming and error-prone. Efforts have been made to automate the process, but current algorithms require large-scale private datasets of up to 20,000 illustrations. With limited data, training a deep learning model is challenging. This study addresses this challenge by developing a fine-tuning strategy with multiple stages. We show that pre-training on a large-scale sketch dataset with initialized weights from ImageNet significantly reduces the mean absolute error (MAE) compared to just training with initialized weights from ImageNet, e.g., ReXNet-200 from 3.1 to 2.2 MAE. Additionally, techniques such as stochastic weight averaging (SWA) and ensembling of different architectures can further reduce the error to an MAE of 1.97.
