Patent number: 11934938Abstract: A computer implemented method for training a neural network to capture a structural feature specific to a set of chemical compounds is disclosed. In the method, the computer system reads an expression describing a structure of the chemical compound for each chemical compound in the set and enumerates one or more combinations of a position and a type of a structural element appearing in the expression for each chemical compound in the set. The computer system also generates training data based on the one or more enumerated combinations for each chemical compound in the set. The training data includes one or more values with a length, each of which indicates whether or not a corresponding type of the structural element appears at a corresponding position for each combination. Furthermore, the computer system trains the neural network based on the training data for the set of the chemical compounds.Type: GrantFiled: December 23, 2020Date of Patent: March 19, 2024Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Satoshi Hara, Gakuto Kurata, Shigeru Nakagawa, Seiji Takeda

Publication number: 20220276600Abstract: An image forming apparatus includes an image forming unit having a plurality of members, a control unit, and a sound collecting unit. The control unit controls operations of the plurality of members in a first operation mode in which the image forming unit forms an image on a recording material.

Publication number: 20220197204Abstract: An image forming apparatus includes a stack portion having recording materials, an image forming unit, a basis weight detection unit, an operating sound detection unit, and a mode selection unit. The basis weight detection unit detects a recording material basis weight based on an ultrasonic wave. The operating sound detection unit detect an abnormality of a generated operating sound.
