Classification Algorithm Basic | Data Science

Classification is a type of supervised learning in data science that involves predicting a categorical target variable based on one or more input variables.
00:10
Here are some popular classification algorithms along with a real time example.
00:15
Logistic regression.
00:18
Logistic regression is a binary classification algorithm that is used to predict the probability of an event occurring.
00:25
It works by fitting A sigmoid function to the input data, which maps the input features to the target variable.
00:32
Real time example.
00:35
Logistic regression can be used in credit scoring to predict whether a loan applicant is likely to default on their loan based on their credit history and other financial factors.
00:46
Decision trees.
00:48
Decision trees are a popular classification algorithm that work by splitting the data into different branches based on the most important features.
00:57
They use a tree like structure to represent the decision making process and can handle both categorical and continuous input variables.
01:06
Real time example.
01:08
Decision trees can be used in customer segmentation to predict the likelihood of a customer buying a particular product based on their demographic and behavioral data.
01:19
Random Forest.
01:21
Random Forest is an ensemble learning method that combines multiple decision trees to improve the accuracy and generalization of the model.
01:30
It works by constructing a set of decision trees on different subsets of the input data and then combining their predictions.
01:38
Real time example.
01:40
Random Forest can be used in fraud detection to predict whether a particular transaction is fraudulent based on a variety of input features such as transaction amount, location, and time.
01:53
Support vector machines, SVMS.
01:56
VMS are a powerful classification algorithm that works by finding the hyperplane that best separates the input data into different classes.
02:06
They are particularly effective in cases where the input data is not linearly separable.
02:12
Real time example.
02:14
SBMS can be used in image classification to predict whether an image contains a particular object or not based on its visual features.
02:24
These classification algorithms are widely used in data science for a variety of applications, such as predicting customer behavior, fraud detection, and image recognition.
