摘要:
Traditional Chinese Medicine (TCM), which originated in ancient China with a history of thousands of years, characterizes and addresses human physiology, pathology, and diseases diagnosis and prevention using TCM theories and Chinese herbal products. Recently, the World Health Organization included TCM in the global diagnostic compendium, which marks the international recognition of TCM in global health care. Considering this, many research works have been devoted to revealing the effectiveness and efficacy of Chinese herbs for new drug discovery in a bottom-up manner. However, the pharmacological principles in TCM theory, the core treasure house of TCM, have rarely been systematically investigated in a top-down manner, which hinders the modernization and standardization of TCM. To bridge the gap, we propose a novel TCM-based artificial intelligence (AI) framework to unravel general patterns and principles of human disease and investigate potential drug-diseases associations. We collect and refine extensive TCM data, as well as biological, chemical, and clinical data, to establish an integrated multi-modal TCM database. Subsequently, we construct a TCM pharmacological network to reveals the underlying structure and patterns within the TCM data. An attention-based AI model is trained to embed multi-modal TCM data into an interpretable pharmacological space, allowing for quantitative and personalized analysis of complex interactions among diseases, symptoms, herbs, compounds, and genes. The pharmacological embedding space with biological significance provides new perspectives toward modern medicine issues from the view of TCM. Our work aims to promote the quantitative underpinning of TCM pharmacological principles, provide a basis for the objectification of the diagnosis and treatment process of TCM, and pave the way for the knowledge fusion of TCM evidence-based medicine and modern biology.

摘要:
Temporal sequence processing is fundamental in brain cognitive functions. Experimental data has indicated that the representations of ordinal information and contents of temporal sequences are disentangled in the brain, but the neural mechanism underlying this disentanglement remains largely unclear. We investigate how recurrent neural circuits learn to represent the abstract order structure of temporal sequences, and how the disentangled representation of order structure facilitates the processing of temporal sequences. We show that with an appropriate training protocol, a recurrent neural circuit can learn tree-structured attractor dynamics to encode the corresponding tree-structured orders of temporal sequences. This abstract temporal order template can then be bound with different contents, allowing for flexible and robust temporal sequence processing. Using a transfer learning task, we demonstrate that the reuse of a temporal order template facilitates the acquisition of new temporal sequences, if these sequences share the same or partial ordinal structure. Using a key-word spotting task, we demonstrate that the tree-structured attractor dynamics improves the robustness of temporal sequence discrimination, if the ordinal information is the key to differentiate these sequences.
