Abstract: The present invention relates to a method for identifying a sound source comprising the following steps: (S1): acquisition of a sound signal; (S2): application of a frequency fitter to the acquired sound signal in order to obtain a filtered signal; (S4): extraction of a matrix of features associated with the filtered signal; (S5): identification of the source by applying a classification model to the feature matrix extracted in step (S4), the classification model having, as its output, at least one class associated with the source of the acquired sound signal.

Abstract: This disclosure describes a method for determining, in real time and continuously, an amount of particles of a given material in a sample, including steps of: E1: optically measuring a signature of the sample by an optical sensor; E2: identifying, by a processing unit, the type of the sample by a classification model trained on a training database including a plurality of reference signatures, each reference signature being associated with a reference sample type; and E3: determining, by the processing unit, the amount of particles of the given material in the sample based on the identified sample type and a correspondence table associating, with each of a plurality of reference sample types, a reference amount of particles of the given material.
