Publication number: 20240330694Abstract: A reward-based reinforcement learning (RL) computing environment with an RL agent has a goal to discovery new polymers. The RL environment is integrated with a logical optimal action (LOA) framework that includes a logical neural network (LNN). The RL environment and the LOA framework share a user interface that switches between the LOA framework and the RL environment. At the LOA interface, polymer datasets are entered into the LOA framework along with subject matter expert (SME)-defined rules that limit the scope of the information in the datasets. The datasets and the SME-defined rules train the LNN to develop policy rules. Upon training completion, the datasets and the LNN policy rules are input into the RL environment where the RL agent makes reward-based decisions on the information in the datasets that advance the goal. At the RL interface, the SME reviews the RL agent's decisions to eliminate decisions that do not advance the goal.Type: ApplicationFiled: March 29, 2023Publication date: October 3, 2024Inventors: Sarathkrishna Swaminathan, Tim Erdmann, Dmitry Zubarev, Subhajit Chaudhury, Asim Munawar

Publication number: 20240143969Abstract: A formulation graph convolution network (F-GCN) with multiple GCNs assembled in parallel and connected to filters and an external learning architecture is able to predict the effectiveness of a formulation. Input into the multiple GCNs are molecular structures of formulants, which are processed as molecular graphs and output as molecular descriptors. The molecular descriptors are filtered by normalized ratios or fractions of the ingredient molecules in a formulation, such as a battery electrolyte or solvent. A formulation descriptor combines the filtered molecular descriptors to arrive at a predicted performance for the formulation, such as the battery capacity for an electrolyte formulation, by an external learning architecture. F-GCN may use a pre-trained GCN with physico-chemical properties of known molecular structures.Type: ApplicationFiled: October 31, 2022Publication date: May 2, 2024Inventors: Vidushi Sharma, Maxwell Giammona, Dmitry Zubarev

Patent number: 11646117Abstract: A method is described that utilizes non-negative matrix factorization to predict susceptibility of a microorganism to an antimicrobial drug. A sparse adjacency matrix is constructed from existing ground truth datasets that include antibiogram data and other data associated with microorganisms. The rows of the adjacency matrix correspond to biosamples, and the columns correspond to instances of metadata and drugs associated with one or more of the biosamples. The elements of the adjacency matrix are assigned non-zero numerical values or zero depending on whether a known association exists. The adjacency matrix is then factored using a selected number of latent factors, thereby producing a reconstruction matrix approximating the adjacency matrix. The values of the reconstruction matrix are used to predict antimicrobial susceptibility of a biosample ID to a drug when antibiogram data are lacking.Type: GrantFiled: June 4, 2019Date of Patent: May 9, 2023Assignee: International Business Machines CorporationInventors: Mark Kunitomi, Dmitry Zubarev, Sarathkrishna Swaminathan
