Gradient Descent is one the key algorithm used in Machine Learning. While training machine learning model, we require an algorithm to minimize the value of loss function. Gradient Descent is one of the optimization algorithm , that is used to minimize the loss. There are mainly three types of Gradient Descent algorithm1. Batch Gradient DescentBatch … Continue reading Difference Between Batch, Mini-Batch and Stochastic Gradient Descent

How to write command-line arguments using argparse in python
If you want to run a .py python file from command line and you also want to pass the argument using command line you can use argparse library. This can be done as below: import argparse # Command Line arguments argp = argparse.ArgumentParser() argp.add_argument('--my_var', dest="my_var", action="store", type=int, default=5) params = argp.parse_args() myvar= params.my_var print(myvar) Then … Continue reading How to write command-line arguments using argparse in python
Handling missing data in pandas data frame python
In this post we are going to discuss how to handle missing data from a pandas data frame. Find total number of missing data in the data frame missing_total = df.isnull().sum().sum() Find number of missing data in each column in a data frame missing_per_column = df.isnull().sum() Investigate patterns in the amount of missing data in … Continue reading Handling missing data in pandas data frame python
int object is not iterable Error
If your code is like below count = 100 for number in count: This will give you error like.. int object is not iterable. In Python, the thing you pass to a for statement needs to be some kind of iterable object. The variable count here is a number which is not iterable. You should … Continue reading int object is not iterable Error
Random Forest Classification in Python in 10 Lines
Random Forest algorithm is like an ensemble algorithm made of Decision Trees, which comprises more than one decision tree to create a model. It creates more than one tree like conditional control statements to create its model hence it is named as Random Forest. Random Forest machine learning algorithm can be used to solve both … Continue reading Random Forest Classification in Python in 10 Lines
