摘要: A fluorescence intensity calculating apparatus, includes a measuring section configured to receive fluorescences generated from plural fluorescent dyes excited by radiating a light to a microparticle multiply-labeled with the plural fluorescent dyes having fluorescence wavelength bands overlapping one another by photodetectors which correspond to different received light wavelength bands, respectively, and whose number is larger than the number of fluorescent dyes, and obtain measured spectra by collecting detected values from the photodetectors, and a calculating section configured to approximate the measured spectra based on a linear sum of single-dyeing spectra obtained from the microparticle individually labeled with the fluorescent dyes, thereby calculating intensities of the fluorescences generated from the fluorescent dyes, respectively.

摘要: Techniques for sorting biological particles are described. The techniques may include applying a data compression process to data indicating light emitted from biological particles and outputting, based on a result of the data compression process, one or more groups of the biological particles to sort into additional groups of the biological particles. The techniques may further include using at least some of the data corresponding to the one or more groups of the biological particles in training at least one statistical model, wherein an output of the at least one statistical model specifies an indication to sort one or more of the biological particles.

摘要: [Object] To provide an information processing apparatus, a particle sorting system, a program, and a particle sorting method that practice a spectral type analysis usable for sorting particles.
[Solving Means] The information processing apparatus according to an aspect of the present technology includes: an analysis unit; a learning unit; and a discrimination unit. The analysis unit calculates fluorophore information indicating respective amounts of luminescence of a plurality of types of fluorophores on the basis of detection data indicating amounts of luminescence of fluorescence at respective wavelength bands, the fluorescence having been emitted from a particle irradiated with excitation light, discriminates whether or not to treat the particle as a process target in accordance with the fluorophore information, and generates teaching data by associating a result of the discrimination with the detection data. The learning unit applies a machine learning algorithm to the teaching data, learns a characteristic of the detection data discriminated as the process target, and generates dictionary data including a result of the learning. The discrimination unit discriminates whether or not the particle whose detection data has been acquired is the process target on the basis of the dictionary data when the detection data is supplied.
