Abstract: A learning apparatus, including: a learning unit configured to learn a parameter of a score function for two-class classification so as to maximize a Partial Area Under the Curve (pAUC), based on training data of a positive instance and a negative instance and a setting value for setting a range of the pAUC; a score calculation unit configured to calculate a score for validation data of the positive instance and the negative instance, using the score function; and an adjustment unit configured to adjust the setting value based on the score.

Abstract: An air conditioner 1 includes: an outdoor heat exchanger 14; an outdoor fan 12 for blowing air to the outdoor heat exchanger; an outdoor fan motor 20 that drives the outdoor fan; an outdoor fan inverter 21 that drives the outdoor fan motor; and a control unit 31 that generates a rotation-speed command voltage for controlling the rotation number of the outdoor fan motor. In addition, the control unit starts a defrost operation of the outdoor heat exchanger, based on the rotation-speed command voltage. In this manner, it is possible to achieve an outdoor device of an air conditioner in which there is no need to provide a current detecting sensor, and it is possible to detect frost formation over the heat exchanger during a heating operation and to perform a defrost operation at low costs.

Abstract: Disclosed is a process for producing an aminoadamantane carbamate derivative which is useful as a significant intermediate of an 11?HSD-1 inhibitor. A process for producing an acid addition salt of a compound represented by the Formula (II): or a solvate of the acid addition salt, wherein R1 and R2 are each independently hydrogen, substituted or unsubstituted alkyl or the like; R3 and R4 are each independently hydrogen, substituted or unsubstituted alkyl or the like; and R5 and R6 are each independently hydrogen, halogen, carboxy, nitro, substituted or unsubstituted alkyl or the like; which comprises separating an acid addition salt of a compound represented by the Formula (II) or a solvate of the acid addition salt by adding an acid to a mixture of syn isomer and anti isomer of a compound represented by the Formula (I): wherein R1, R2, R3, R4, R5, and R6 are as defined above, in the presence of a solvent.
