Patent number: 11587646Abstract: A variational autoencoder (VAE) has been developed to learn a continuous numerical, or latent, representation of molecular structure to expand reference libraries for small molecule identification. The VAE has been extended to include a chemical property decoder, trained as a multitask network, to shape the latent representation such that it assembles according to desired chemical properties. The approach is unique in its application to metabolomics and small molecule identification, focused on properties that are obtained from experimental measurements (m/z, CCS) paired with its training paradigm, which involves a cascade of transfer learning iterations. First, molecular representation is learned from a large dataset of structures with m/z labels. Next, in silico property values are used to continue training. Finally, the network is further refined by being trained with the experimental data.Type: GrantFiled: December 3, 2019Date of Patent: February 21, 2023Assignee: Battelle Memorial InstituteInventors: Sean M. Colby, Ryan S. Renslow

Patent number: 11249400Abstract: Systems, metrology modules and methods are provided, which identify, per wafer site, components of residuals from measurement of metrology metric(s), and optimize measurement parameters for each site, according to the identified residuals' components. Certain embodiments utilize metric landscapes to identify sensitive sites and/or to identify sites exhibiting highest accuracy, and corresponding metrics may be combined over the wafer to further enhance the metrology performance. Zonal analysis may be used to reduce the systematic errors, and disclosed per-site analysis may be used to further reduce the non-systematic error components, and relate the remaining residuals components to process variation over the wafer.Type: GrantFiled: September 30, 2019Date of Patent: February 15, 2022Assignee: KLA CORPORATIONInventors: Lilach Saltoun, Tal Marciano, Dana Klein

Patent number: 11243248Abstract: Symbolic backend for execution of quantum programs is provided. A parser receives an input qasm and parses it as a circuit graph. A layering component segments the circuit graph into multiple layers. An evaluation engine reads respective layers, translates the respective layers into a mathematic expression over qubits, and performs a simplification of the input qasm. A checker determines whether the input qasm and the simplified qasm are equivalent.Type: GrantFiled: October 11, 2018Date of Patent: February 8, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Peng Liu, Marco Pistoia
