MOLECULAR PROPERTY PREDICTION USING EDGE-INFORMATION FUSED GLOBAL GRAPH-READ NEURAL NETWORK FUNCTION
Publication number: 20230132463Abstract: This disclosure relates generally to system and method for molecular property prediction. The disclosed method includes mapping node embeddings of a molecular graph to a graph-level embedding characterizing the molecular graph. The graph level representation is acquired by pooling characteristics of hidden states of the nodes in the molecular graph by performing an iterative content based attention in a plurality of iterations. The content based attention is performed by considering an edge information fused transformed hidden state vector of the nodes of the molecular graph. The graph level embedding is fed through the linear projection to predict the molecular properties of the molecular graphs.Type: ApplicationFiled: April 29, 2022Publication date: May 4, 2023Applicant: Tata Consultancy Services LimitedInventors: Sagar Srinivas SAKHINANA, Venkata Sudheendra BUDDHIRAJU, Sri Harsha NISTALA, Venkataramana RUNKANA -
Publication number: 20230134595Abstract: This disclosure relates generally to system and method for molecular property prediction. The method utilizes a set-pooling aggregation operator to derive a graph-level representation of a complete input molecular graphs to assist in inductive learning tasks. The method includes iteratively down-sampling the molecular graph into a coarsened molecular graph, and determining adjacency matrix and feature matrix of the coarsened molecular graph. The method then includes computing an average of the hidden state node attributes of the coarsened graph obtained after preforming the iterations to obtain a graph level representation vector of the molecular graph. Using a linear layer from the graph level representation vector the molecular properties are determined.Type: ApplicationFiled: April 28, 2022Publication date: May 4, 2023Applicant: Tata Consultancy Services LimitedInventors: Sagar Srinivas SAKHINANA, Venkata Sudheendra Buddhiraju, Sri Harsha Nistala Buddhiraju, Venkataramana Runkana

Publication number: 20230116680Abstract: This disclosure relates generally to system and method for molecular property prediction. The conventional methods for molecular property prediction suffer from inherent limitation to effectively encapsulate the characteristics of the molecular graph. Moreover, the known methods are computationally intensive, thereby leading to non-performance in real-time scenarios. The disclosed method overcomes the limitations of typical dynamic neighborhood aggregation (DNA) method by fusing the static edge attributes in determining the self-attention coefficients. In an embodiment, the disclosed method transforms the hidden state of a sink node by utilizing a neural-net function, which takes as input an aggregated single-message vector obtained by the self-attention mechanism and the self-attention mechanism transformed hidden state of the node.Type: ApplicationFiled: May 26, 2022Publication date: April 13, 2023Applicant: Tata Consultancy Services LimitedInventors: SAGAR SRINIVAS SAKHINANA, VENKATA SUDHEENDRA BUDDHIRAJU, SRI HARSHA NISTALA, VENKATARAMANA RUNKANA

Publication number: 20230115719Abstract: This disclosure relates generally to Error! Reference source not found.system and method for molecular property prediction. The conventional methods for molecular property prediction suffer from inherent limitation to effectively encapsulate the characteristics of the molecular graph. Moreover, the known methods are computationally intensive, thereby leading to non-performance in real-time scenarios.
