Latest Patents
One of his latest patents is titled "Question generation systems and methods for automating diagnosis." This invention discloses systems and methods for generating questions that help obtain more relevant medical information based on observed symptoms from patients. The process involves querying a knowledge graph to generate possible diseases associated with the observed symptoms. Additionally, candidate symptoms related to these diseases are identified and combined with the observed symptoms to create comprehensive symptom sets. The invention also includes methods for determining discriminative scores for these candidate symptom sets, allowing for the selection of the most relevant symptoms. If conflicts arise with observed symptoms, those candidate symptoms are removed from consideration. Ultimately, questions are generated based on the selected candidate symptoms to aid in collecting patient information.
Another significant patent by Nan Du is "Systems and methods for relation inference." This invention presents methods and systems that utilize deep learning techniques for data mining documents to discover relationships between terms of interest within specific fields. In the healthcare domain, this system mines large-scale medical documents to extract symptom and disease terms, generating relation information that assists in disease diagnosis. The invention employs recurrent neural networks (RNNs), such as Long Short-Term Memory (LSTM) and Gated Recurrent Units (GRU), to analyze co-occurrences of terms within documents, thereby discovering correlations that can predict statistically probable terms related to given search terms.
