Human behavior recognition method based on accelerometer

The invention discloses a human behavior recognition and classification method based on an accelerometer. The method includes the first step of collecting human behavior samples as a training set, the second step of searching for a projection matrix U which is optimal for the recognition and classification of the training set, the third step of carrying projection on no-labeled data, and the fourth step of classifying the projected data by using a minimum distance classifier to obtain a recognition result. According to the human behavior recognition method, a partial approximate linear hypothesis is carried out on adjacent blocks formed by labeled data so as to enable the distance between different types of samples on the blocks to be large enough, positional sequence information of the same type of samples is reserved as far as possible through class sigmoid function penalty factors, and finally a global objective function is established on the basis of the objective functions on all blocks. The human behavior recognition method can reserve the information of the distance between the samples in a higher dimensional space properly, and reduces dependence of recognition models on artificial tagging samples, and the recognition effect is superior to a representative human behavior recognition method based on linear discriminant analysis.

Preparation method of selenium-rich edible vinegar

The invention discloses a preparation method of a selenium-rich edible vinegar. In the invention, the selenium-rich edible vinegar is brewed through a solid state fermentation process of raw materials comprising selenium-rich corn and sorghum, selenium is chelated with Daqu powder and Aspergillus albicans as a saccharification agent and proteins in a protease enzymatic hydrolysis raw material in the Daqu powder as oligopeptide substances or amino acid, and stable organic selenium is formed through a biochemical reaction of a fumigating process, so it is beneficial to realize human body absorption and function performance; and selenium-containing drinking water is used when the used Aspergillus albicans is cultured in order to induce the Aspergillus albicans to generate an enzyme system converting inorganic selenium to organic selenium. The fumigating process maintains a temperature in a range of 105-110DEG C, and can promote the chelation of peptides amino acids and selenium in order to form a stable organic compound. The selenium-rich brewed edible vinegar prepared through the method has the advantages of stable selenium compound, good color, excellent fragrance and good taste, and has strong health functions, and the content of selenium in 1kg of the finished vinegar is 0.98-1.20mg.
