  • Patent number: 11563654
    Abstract: A detecting device obtains a network log and a host log of a device. The detecting device converts the network log into a network feature value in a form which is inputtable to a multimodal generative model which generates output data on the basis of multiple latent variables represented by random variables. The detecting device converts the host log into a host feature value in a form which is inputtable to the generative model. The detecting device also inputs at least one of the network feature value and the host feature value to the generative model and calculates output data. The detecting device detects an abnormality about the device using an anomaly score calculated on the basis of the output data.

  • Patent number: 11258914
    Abstract: An information processing apparatus includes an acquisition unit, notification control unit, input unit, and extension unit. The acquisition unit acquires a measurement result obtained by measuring a printing medium characteristic and acquires a characteristic reference range of each of printing media types set in advance to identify a type of a measured printing medium. Extracting, as a candidate printing medium and based on the acquired measurement result and the acquired characteristic reference range, a type of printing medium using the characteristic reference range including the measurement result and notifying information indicating the type of the candidate printing medium are performed. The input unit inputs information, wherein a type of printing medium on which recording is to be performed by the recording unit has a first reference range which is the characteristic reference range of the type and corresponds to the input information. The extension unit extends the first reference range.

  • Publication number: 20210024315
    Abstract: A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.
