1, different meanings: bimodal means that in statistics, the data distribution under a certain measure presents two peaks, for example, when the sample data set distribution under a certain random variable presents two peaks, it can be called "bimodal distribution"; Shuang Yuan refers to the situation that one signal source is divided into two or more signal sources in signal processing.
2. Different application fields: Double peaks are commonly used in statistics for data analysis and modeling to describe some special data distribution, such as birth rate and meteorology. Shuang Yuan is mainly used to separate signals from different sources in signal processing, such as satellite communication and Internet of Things monitoring.
Bimodal and Shuang Yuan are two different concepts in the fields of statistics and signal processing, which are mainly used to describe the special situation of data distribution and signal source separation. Their application scenarios, characteristic parameters and processing methods are quite different.
