Abstract: An input data generation unit is configured to generate, based on log data indicating a log of a behavior of a user with respect to a given computer resource for each period, input data for the period, which is associated with the log data. A user probability data generation unit is configured to generate user probability data based on output obtained from a trained machine learning model when the input data is input to the trained machine learning model. An anomaly determination unit is configured to determine whether an anomaly has occurred in the behavior of the user during a latest period based on the user probability data generated based on the input data for the latest period and the user probability data generated based on the input data for a period before the latest period.

Abstract: An information processing apparatus having a first fitness calculation to calculate a fitness using a predetermined function for models in a population; a virtual model generating to select, as parent models, models having higher value of the fitness using the first fitness calculation among the models, and generate a virtual model that outputs by performing calculation of output results of the selected parent models; a second fitness calculation to calculate the fitness of the virtual model using the predetermined function; a replacing operation constituting the population by adding the virtual model and by deleting a model having lower value of the fitness among the models in the population; and a model extracting to extract a model having higher value of the fitness from the population by repeating processing by the virtual model generating, the second fitness calculation, and the model replacing until a predetermined termination condition is reached.

The container rim 120 has an outer peripheral horizontal top surface 122 and an inner peripheral horizontal top surface 124 vertically above the outer peripheral horizontal top surface. The lid 104 includes a ring-shaped lid frame 130 and a membrane 132 that is attached over a top surface of the lid frame 130 and seals with inner peripheral horizontal top surface.

Abstract: A container having a pair of side walls and end walls and corner walls being provided between a respective end wall and side wall, a flange formed on one of the corner walls, said flange functioning as a hinge, a ring member formed integrally with the flange, the ring being sized to sit on top of the container.

Abstract: The assembly (100) includes a container (102) and a lid (104). The container (102) includes a main body (110) and a container rim (120) surrounding the main body (110). The container rim (120) has an outer peripheral horizontal top surface (122) and an inner peripheral horizontal top surface (124). The outer peripheral horizontal top surface (122) surrounds the inner peripheral horizontal top surface (124) and is vertically below the inner peripheral horizontal top surface (124). The lid (104) includes a ring-shaped lid frame (130) and a membrane (132) that is attached over a top surface of the lid frame (130). The lid frame (130) includes a flat strip portion (134) having a continuous flat top surface and a continuous flat bottom surface, which bottom surface engages the outer peripheral horizontal top surface (122) when the lid (104) is in a closed position. The lid frame (130) also includes at least one latching tab (136, 138) that is made integral with an outer edge of the flat strip portion (134).

Abstract: A spool suitable for receiving windings of wire or the like, the spool having a center core formed of a paperboard material, first and second end flanges secured to opposite ends of the center core, the flanges being formed of a plastic material, each flange having at least one circumferentially extending solid portion and an inner portion adjacent to the inner core, the spool having a plurality of sinuous members extending between the solid portion and the outer portion. There is also disclosed an embodiment wherein the flange is substantially solid with a circumferentially extending apertures being formed in the center core.
