    • A pattern recognition system includes a learning unit, a learning unit, a threshold calculation unit, and a determining unit. The learning unit learns, based on learned data of a first pattern, a model for determining whether recognition object data is the first pattern. The learning unit calculates likelihood indicating how likely the recognition object data is the first pattern by using the model learned by the learning unit. The threshold calculation unit calculates a threshold to be compared with the likelihood to determine whether the recognition object data is the first pattern, based on first likelihood that is calculated with respect to learned data of the first pattern and second likelihood that is calculated with respect to learned data of a second pattern. The determining unit determines whether the recognition object data is the first pattern by using the threshold.
    • 模式识别系统包括学习单元,学习单元,阈值计算单元和确定单元。 学习单元基于第一模式的学习数据学习用于确定识别对象数据是否是第一模式的模型。 学习单元通过使用由学习单元学习的模型来计算表示识别对象数据是第一模式的可能性的可能性。 阈值计算单元基于相对于第一模式的学习数据计算的第一似然度和相对于第一模式计算的第二似然值,计算要与确定识别对象数据是否是第一模式的可能性进行比较的阈值 学习了第二种模式的数据。 确定单元通过使用阈值来确定识别对象数据是否是第一模式。
