The general approach of signal detection theory has direct application for us in terms of sensory experiments. But it also offers a way to analyze many different kinds of decision problems. WebFalse rejection occurs when the system rejects a valid speaker, and false acceptance when the system accepts an imposter speaker. Both types of error are a function of the decision threshold used in the template matching and nearest neighbor methods. Choosing a high threshold of acceptance will result in high FRR (low FAR). うどんスープ 作り方
