How to deal with data ambiguity in TEC-006

Today, I will talk to you about how to carry out TEC-006 data fuzzy processing, which may not be well understood by many people. In order to let everyone know more, Xiaobian summarizes the following contents for everyone. I hope everyone can gain something according to this article.

Data in the user layer to do fuzzy processing, continuous data range, no overlap, think of a solution, through the range of the beginning of the position sort by binary search to obtain fuzzy value interval;

The data conversion format is as follows:

eg.1

Below 50 (=50,=70,=90,=110,=130,=150,=200)

eg.2

Within a month (0-30 days)

Within two months (31-60 days)

Within 3 months (61-90 days)

Within half a year (91-180 days)

Within one year (181 days-365 days)

More than one year (365 days)

demo:

class VlCode {

const CONSTRUCTION_AREA=[50,70,90,110,130,150,200];

const FINAL_PRICE=[100,150,200,250,300,400,500,800,1000];

const LOAN_AMOUNT=[30,50,100,150,200,250,300,400,500];

const LOAN_DATE=[30,31,60,61,90,91,180,181,365];

const LOAN_DATE_CEIL=[

'-1'=>"within a month",

'1'=>"within two months",

'3'=>"within three months",

'5'=>"within half a year",

'7'=>"within one year",

'9'=>"More than one year"
