Immunisation method for user behaviour model detection in electronic transaction process

An immunization detection method for a user behavior mode in an electronic transaction process, comprising a data preprocessing step of mainly processing a user operation process into a sequence format and cleaning related repeated data; a training step of mainly calculating an age value of each sequence according to a time order and according to an age evolution process, deleting aged logs according to the age values and extracting a normal sequence library; a detection step of mainly detecting whether a newly generated transaction sequence is mutated or not; and an updating step of updating age values of selves and non-selves in time according to a detection result and updating a related library set. The method is oriented to abnormal situations in the electronic transaction process, which may be misoperation by users.. ... Tongji University

Clustering coefficient-based adaptive clustering method and system

A clustering coefficient-based adaptive clustering method, according to the categories of extracted data point pairs and the magnitude of association relations between data points extracted each time, determining to which category the data points belong, and the number of the categories, and establishing association relations between the data points and association relations between the categories; pre-segmenting each category and calculating the intra-category similarities of two sub-categories and inter-category similarities of the two sub-categories, judging whether the two pre-segmented sub-categories satisfy a segmentation condition, if so, then accepting the pre-segmentation; if not, then canceling the pre-segmentation; calculating the intra-category similarities and inter-category similarities of two categories having an association relation, judging whether the two categories satisfy a merging condition, if so, then merging the two categories to generate a new category; if not, then abandoning the merging.. . ...

Image compression method and apparatus using matching

The present invention is to code a current pattern using a reference pattern that has different shape and/or size from the current pattern being coded. A portion or entire of the reference pattern provides reference pixels for one part of the current pattern. ... Tongji University

Method of inhibiting formation of dioxins and dioxin-like compounds in solid waste incineration flue gas

The present invention relates to a method for inhibiting the formation of dioxin-like compounds in solid waste incineration flue gases, belonging to the field of cleaning of solid waste incineration flue gases. In accordance with the present invention, when incineration flue gases cool down to 500˜450° c., the flue gases are introduced into an inhibition reactor where copper chlorides in flue gas particulates mix and react with inhibitors to convert into copper metaphosphate so as to inactivate the copper chlorides which can catalyze the formation of dioxin-like compounds and control dioxin-like compound pollutants in incineration flue gases at the source. ...
