Abstract: A system calculates an inter-distribution distance between target data and base data for each of one or more second periods in an entire period between an end time of a first period and a relearning timing of a learning model. For each second period, the target data is data for the second period in the entire data that is data for the entire period. The base data is data for the first period and is data related to creation of the learning model. The system specifies, as a variation point, a time in accordance with the second period during which the calculated inter-distribution distance is greater than or equal to a threshold. The system determines and outputs one or more training data candidates from a part or all of the entire data based on the one or more variation points for relearning of the learning model.

Abstract: A working vehicle includes a vehicle body, a cabin on the vehicle body, a clutch pedal in the cabin, a clutch on the vehicle body, a clutch operator to engage and disengage the clutch, a linkage including first and second ends, the first end being connected to the clutch operator, and a linkage lock to interlock the clutch pedal with the second end of the linkage so that vibrations of the cabin are reduced or prevented from being transmitted to the clutch.

Abstract: A power transmission device includes a first shaft provided to be rotatable around a first rotational axis of the hydraulic pump driven by the engine. A second shaft is rotatable about the first rotational axis to rotate the power take shaft. A clutch is rotatable about a second rotational axis that is substantially parallel to the first rotational axis and is vertically below the first rotational axis. The clutch has a first rotating portion and a second rotating portion arranged to face each other in the second rotational axis. A first rotating portion is connectable to and separable from the second rotating portion. The first rotation transmission mechanism is configured to transmit rotation of the first shaft to the first rotating portion. A second rotation transmission mechanism is configured to transmit rotation of the second rotating portion to the second shaft.

Abstract: Provided are a time series data management unit that manages time series data generated in a target system, and a context management unit that manages a context registered by a user in association with time series data managed by a time series data management unit. The context management unit executes a process of extracting time series data associated with a context set as a search target by the user out of the managed time series data.

Abstract: A sequential data analysis unit that cyclically generates a model for analyzing time-series data representing an operational status of an analysis target system using a clustering technology; and a management unit that manages the model, parameter information of the model, a classification result of the time-series data by the clustering technology, and version information given each time the model is generated are included. Then, when the version information of the model is selected, the management unit executes processing of regenerating the model by using the parameter information associated with the selected version information and the classification result of the time-series data.
