    Abstract: Disclosed is a method for performing image convolution by considering a hierarchical relationship of hyperbolic feature vectors in a hyperbolic space. According to an embodiment of the present disclosure, an image convolution method in a hyperbolic space includes steps of embedding an image feature vector on a Euclidean space into a hyperbolic feature vector on a hyperbolic space, allocating a hierarchical weight on the hyperbolic feature vector based on a hierarchical property of the hyperbolic feature vector, and convolutioning the hyperbolic feature vector by applying the hierarchical weight.

    Abstract: The present invention relates to a multi-microorganism detection system, and more particularly, to a multi-microorganism detection system using a dielectrophoresis force. Provided is a rapid and accurate multi-microorganism detection system. Microorganisms are concentrated at a high throughput using DEP after synthesizing the microorganisms and fluorescent magnetic particles, and when a complex in which the fluorescent magnetic particles are bound to the microorganisms passes through a detection unit by moving only the microorganisms to the detection unit after separating the magnetic particles from the complex (i.e., the microorganisms to which the magnetic particles are bound) using a DEP force, a fluorescence signal of a specific wavelength band is generated according to the type of the fluorescent magnetic particle and the concentration of the microorganisms according to the type of microorganism is measured by measuring and analyzing the fluorescence signal.
