DF2DB

class geoanalytics.conversion.DF2DB.DF2DB(inputDF, DFtype='dense')[source]

Bases: object

Description:

This class will create database for given DataFrame based on Threshold values and conditions are defined in the class. Converts Dataframe into sparse or dense dataframes.

Attributes:
param inputDF:

DataFrame : It is sparse or dense DataFrame

param thresholdValue:

int or float : It is threshold value of all item

param condition:

str : It is condition of all item

param DFtype:

str : It is DataFrame type. It should be sparse or dense. Default DF is sparse.

:param memoryUSSfloat

To store the total amount of USS memory consumed by the program

:param memoryRSSfloat

To store the total amount of RSS memory consumed by the program

:param startTimefloat

To record the start time of the mining process

endTimefloat

To record the completion time of the mining process

Importing this algorithm into a python program

from PAMI.extras.DF2DB import DF2DB as db

obj = db.DF2DB(idf, "sparse/dense")

obj.convert2Transactional("outputFileName",condition,threshold) # To create transactional database

obj.convert2Temporal("outputFileName",condition,threshold) # To create temporal database

obj.convert2Utility("outputFileName",condition,threshold) # To create utility database
convert2MultipleTimeSeries(oFile: str, condition: str, thresholdValue: int | float, interval: int) → None[source]
Description:
