Abstract: A method for aging and storage of Jiang-flavor raw liquor involves “growing, nourishing and storing.” The Jiang-flavor new liquors of different rounds are subjected to outdoor storage in jars for not more than 1 year, then the Jiang-flavor raw liquors of different rounds having experienced the outdoor storage in jars for not more than 1 year are blended and put into stainless steel tank for blending and aging for a period of 1 to 2 years, and finally the Jiang-flavor raw liquor having experiencing the blending and ageing in the stainless steel tank for 1 to 2 years undergoes indoor storage in jars for 2 to 10 years. The method combines different storage containers with different storage years, improving the aging and storage effect and the quality of the Jiang-flavor raw liquor in a targeted manner.

Abstract: Techniques are disclosed for building a dictionary of words from combinations of symbols generated based on input data. A neuro-linguistic behavior recognition system includes a neuro-linguistic module that generates a linguistic model that describes data input from a source (e.g., video data, SCADA data, etc.). To generate words for the linguistic model, a lexical analyzer component in the neuro-linguistic module receives a stream of symbols, each symbol generated based on an ordered stream of normalized vectors generated from input data. The lexical analyzer component determines words from combinations of the symbols based on a hierarchical learning model having one or more levels. Each level indicates a length of the words to be identified at that level. Statistics are evaluated for the words identified at each level. The lexical analyzer component identifies one or more of the words having statistical significance.

The mapper component generates one or more clusters based on a statistical distribution of the normalized vectors. The mapper component evaluates statistics and identifies statistically relevant clusters. The mapper component assigns a distinct symbol to each of the identified clusters.
