In this paper, according to the characteristics of non linear networktraffic, traffic behaviors are decomposed into trenditems, perioditems, and randomitems by an accumulation decomposition model.
In addition to the normal targets of money, jewels, cars and videos, there is a new trend in the city towards stealing items such as Crazy Colour hair-dye, iced buns and biscuits.
We believe that this increase can be attributed to an increase in household spending in essential items, coupled with a decline in national income, a trend observed by the Discover U.S. Spending Monitor.
