Abstract: In an information processing system, an estimation as to whether a sound collected by a microphone is steady sound or non-steady sound is executed, sound information estimated to indicate the non-steady sound is transmitted to a server as output sound information when it is estimated that it is the non-steady sound, and the server acquires the output sound information, and estimates an action of a person from a resulting output obtained by inputting the output sound information to a second trained model indicative of a relevance between the output sound information and action information on an action of a user.

Abstract: A state quantity estimation device includes: a sound collector that collects, in the vicinity of a secondary battery without contact with the secondary battery, a sound emitted from the secondary battery during charge or discharge of the secondary battery; an estimator that estimates a state quantity indicating a state of the secondary battery, based on information on the sound collected by the sound collector; and an outputter that outputs the state quantity estimated by the estimator.

Abstract: A sentence evaluation apparatus evaluates a sentence which is input. The sentence evaluation apparatus includes an acquisition device and a processor. The acquisition device acquires information indicating a first input sentence and information indicating a second input sentence. The processor executes information processing on the information acquired by the acquisition device, using an algorithm based on machine learning. The processor includes a first encoder that recognizes the first input sentence and a second encoder that recognizes the second input sentence, in the algorithm based on the machine learning. The processor generates evaluation information indicating evaluation on the first input sentence with reference to the second input sentence, based on a result of recognition by the first encoder on the first input sentence and a result of recognition by the second encoder on the second input sentence.

Abstract: A translation device is configured to acquire utterance spoken by a speaker in a first language and translate contents of the utterance into a second language for information presentation, and includes an input unit, a controller, a notification unit, and a storage. The input unit acquires the utterance in the first language and generates voice data from the utterance. The controller acquires a first evaluation value. The notification unit presents the speaker with information on utterance reinput request. The notification unit presents first information on utterance reinput request when the first evaluation value is less than or equal to a first predetermined value. The controller generates new voice recognition data with reference to the past voice recognition data and voice recognition data of reinput utterance, when the voice recognition data of the reinput utterance has an evaluation value less than or equal to a predetermined value.

Abstract: A reflective plate comprises a substrate, a plurality of protrusions each formed on the substrate and having a curved surface, and a reflective film formed on the substrate having the protrusions, wherein a planar shape of each of the protrusions is indefinite, and when a frame line of the planar shape of each of the protrusions is divided into fine line segments, the line segments are pointed in all directions or in predetermined directions. This improves reflective properties such as dispersion properties.

Abstract: A method of measuring quantities that indicates the state of an electrochemical device having an electrode and an ionic conductor, such as material properties or a residual capacity, without disassembling the device. The quantities are measured by comparing (a) a series of theoretical data of an electrical characteristic of the device obtained by combining at least one of an electron transportation model of the electrode, an ion transportation model of the electrode, an ion conduction model of the ionic conductor and a model of an electrochemical reaction taking place in an interface between the electrode and the ionic conductor, with a potential model of the electrode, with (b) a series of measured data of the electrical characteristic of the electrochemical device.
