Learn Machine Learning Algorithms

Machine Learning Algorithms with Python Code Contents of Algorithms  1.  ML Linear regression A statistical analysis technique known as "linear regression" is used to simulate the relationship between a dependent variable and one or more independent variables. 2.  ML Logistic regression  Logistic regression: A statistical method used to analyse a dataset in which there are one or more independent variables that determine an outcome. It is used to model the probability of a certain outcome, typically binary (yes/no). 3.  ML Decision trees Decision trees: A machine learning technique that uses a tree-like model of decisions and their possible consequences. It is used for classification and regression analysis, where the goal is to predict the value of a dependent variable based on the values of several independent variables. 4.  ML Random forests Random forests: A machine learning technique that uses multiple decision trees to improve the accuracy of predicti...

What is Naive Bayes algorithm

Naive Bayes Algorithm with Python Concepts of Naive Bayes Naive Bayes is a classification algorithm based on Bayes' theorem, which states that the probability of a hypothesis is updated by considering new evidence. Since it presumes that all features are independent of one another, which may not always be the case in real-world datasets, it is known as a "naive". Despite this limitation, Naive Bayes is widely used in text classification, spam filtering, and sentiment analysis. Naive Bayes Algorithm Define the problem and collect data. Choose a hypothesis class (e.g., Naive Bayes). Compute the prior probability and likelihood of each class based on the training data. Use Bayes' theorem to compute the posterior probability of each class given the input features. Classify the input by choosing the class with the highest posterior probability. Evaluate the model on a test dataset to estimate its performance. Here's an example code in Python for Naive Bayes: Python cod...

What is Linear regression

Linear regression A lgorithm Concept of Linear regression In order to model the relationship between a dependent variable and one or more independent variables, linear regression is a machine learning algorithm. The goal of linear regression is to find a linear equation that best describes the relationship between the variables. Using the values of the independent variables as a starting point, this equation can then be used to predict the value of the dependent variable. There is simply one independent variable and one dependent variable in basic linear regression. The linear equation takes the form of y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept. For example, let's say we have a dataset of the number of hours studied and the corresponding test scores of a group of students. We can use linear regression to find the relationship between the two variables and predict a student's test scor...

What is Logistic regression

Logistic Regression  Algorithm Concept of Logistic Regression A machine learning approach called logistic regression is used to model the likelihood of a binary outcome based on one or more independent factors. The goal of logistic regression is to find the best-fitting logistic function that maps the input variables to a probability output between 0 and 1. The logistic function, also known as the sigmoid function, takes the form of:   sigmoid(z) = 1 / (1 + e^-z)   where z is a linear combination of the input variables and their coefficients. For example, let's say we have a dataset of customer information, including their age and whether they have purchased a product. We can use logistic regression to predict the probability of a customer making a purchase based on their age. Logistic Regression  Algorithm: Define the problem and collect data. Choose a hypothesis class (e.g., logistic regression). Define a cost function to measure the difference between predic...

What is Convolutional and Recurrent Neural Networks

Convolutional Neural Networks and Recurrent  Neural Networks Algorithms Convolutional NN - Recurrent NN Concepts Neural networks, including deep learning architectures such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) The machine learning technique known as neural networks was inspired by the design and function of the human brain. They consist of interconnected nodes, or "neurons", that process and transmit information to each other to make a prediction or decision. Deep learning architectures such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) are advanced neural network structures that have proven to be highly effective in a variety of applications including time series analysis, natural language processing, and picture and audio recognition. Convolutional Neural Networks (CNNs) are a type of neural network that is designed to process and analyze image data. They use convolutional layers, which apply ...
