  • Publication number: 20230409904
    Abstract: A method and system of predicting molecular properties is provided herein. The method includes representing a molecule as a graph and a string. The method further includes encoding the graph into a first feature representation and the string into a second feature representation, using a graph neural network and a transformer-based network, respectively. The method further includes concatenating the first feature representation obtained from the graph neural network and the second feature representation obtained from the transformer-based network to create a combined feature representation. The method further includes fusing the combined feature representation using a linear layer to obtain a synergistic combined feature representation for the molecule. The method further includes predicting one or more molecular properties for the molecule using the synergistic combined feature representation and a predictor network.

  • Publication number: 20230316096
    Abstract: The disclosure provides a system, a method, and a computer program product for displaying a a Knowledge Graph at a client device. The method comprises receiving a sequence of selection elements in the Knowledge Graph, by a user. The method may include displaying the sequence of selected elements in a last in, first out order on selecting a UI component by the user. Also, the method may enable saving a state of display on closing display of the Knowledge Graph. Further, on reopening the display of the Knowledge Graph the saved state is rendered. The method also provides box select and panning feature for visually manipulating the Knowledge Graph. Further, in order to optimally execute the above features, nodes and edges which are the elements of a Knowledge Graph are stored in array data structures.

  • Publication number: 20230317279
    Abstract: Disclosed is an AI-based method for medical diagnosis, comprising: obtaining medical data from data source(s); generating a Directed Acyclic Graph (DAG) (204) using medical data, wherein nodes of DAG represent at least set of symptoms and set of medical conditions, and wherein directed edges between nodes represent relations between nodes; generating graph embeddings for nodes of DAG using graph-embedding technique; receiving input indicative of person's health, wherein input comprises set of symptoms (202); extracting set of test graph embeddings corresponding to test set of symptoms from graph embeddings; and processing test graph embeddings using neural network (206) for obtaining multi-label classification (208) of test set of symptoms matched to test set of medical conditions as labels, wherein given label is probabilistically indicative of presence of medical condition.

  • Publication number: 20230252062
    Abstract: The disclosure provides a system, a method, and a computer program product for displaying a sentence in a Knowledge Graph at a client device. The method comprises displaying, at the client device, at least an entity in the Knowledge Graph as a node. The method may include displaying, at the client device, at least a relation in the Knowledge Graph as an edge. The method may further include, displaying, at the client device, a sentence on selecting the edge of the Knowledge Graph, wherein the sentence is a natural language expression associated with the relation. The method also allows for visually adjusting the display density of the Knowledge Graph.
