NumberImputation

class geoanalytics.imputation.NumberImputation.NumberImputation(dataframe)

Bases: object

About this algorithm

Description:

Number Imputation replaces missing values in the dataset with a specified fixed numeric value. This is a straightforward method useful when you want to impute all missing values with a constant number, such as zero or any other specified numeric value.

Parameters:

• Dataset (pandas DataFrame) must be provided during object initialization.

• number (int or float) to replace missing values during the run() method (default is 0).

Attributes:

• df (pd.DataFrame) – The input data with ‘x’, ‘y’ coordinates and features.

• imputedDF (pd.DataFrame) – DataFrame after filling in missing values with the specified number.

• startTime, endTime (float) – Variables to track execution time.

• memoryUSS, memoryRSS (float) – Memory usage of the imputation process in kilobytes.

Execution methods

Calling from a Python program

import pandas as pd

from geoanalytics.imputation import NumberImputation

df = pd.read_csv("input.csv")

number_imputer = NumberImputation(df)

imputed_df = number_imputer.run(number=0)

number_imputer.getRuntime()
number_imputer.getMemoryUSS()
number_imputer.getMemoryRSS()

number_imputer.save('NumberImputation.csv')

This implementation was created by Raashika and revised by M.Charan Teja under the guidance of Professor Rage Uday Kiran.

getMemoryRSS()

Prints the memory usage (RSS) of the process in kilobytes.

getMemoryUSS()

Prints the memory usage (USS) of the process in kilobytes.

getRuntime()

Prints the total runtime of the clustering algorithm.

run(number=0)

Executes the number imputation algorithm by filling missing values with the specified number.

Parameters:

number – int or float, the numeric value to fill missing data (default 0)

Returns:

imputedDF (pd.DataFrame) – DataFrame with missing values filled

save(outputFile='NumberImputation.csv')

Saves the imputed DataFrame to a CSV file.

Parameters:

outputFile – str, filename to save the imputed data (default: ‘NumberImputation.csv’)
