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 Bayesian networks

Bayesian networks Algorithm Concepts of Bayesian networks A Deep learning architectures such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs)  Each node is associated with a probability distribution, and the edges represent the conditional dependencies between those distributions.   Bayesian networks can be used for probabilistic reasoning and decision-making by inferring the probability of a particular event, given some evidence or observations. They can also be used for decision-making by selecting the action that maximizes some expected utility.   One of the most popular algorithms for probabilistic reasoning in Bayesian networks is called the belief propagation algorithm . This algorithm uses a message-passing approach to compute the marginal probabilities of the nodes in the network.   Let's consider an example to illustrate how Bayesian networks can be used for probabilistic reasoning and decision-making. Suppose we want t...

What is Association Rule Mining

Machine Learning Association Rule Mining Algorithms  Concepts of Association Rule Mining Association Rule Mining is a technique of data mining used for finding co-occurrence relationships and patterns in large datasets. It is employed to glean intriguing connections between variables in sizable databases. The relationships discovered in Association Rule Mining are represented in the form of rules, where the antecedent and consequent are a set of items.   There are several algorithms used in Association Rule Mining, such as Apriori, FP-Growth, ECLAT, and more. Among these algorithms, Apriori is the most widely used algorithm for Association Rule Mining.   The item sets that do not match the minimal support criterion are pruned by the Apriori algorithm after it generates a candidate set of item sets. The support threshold is a user-defined value that determines the minimum frequency of an item set to be considered as frequent. Association Rule Mining  Algorithm Def...

What is Decision Boundary Algorithms

Machine Learning  Decision Boundary Algorithms Decision Boundary Algorithms Concepts Decision boundary algorithms are used in machine learning to create a boundary that separates different classes or groups in a dataset. They are used to classify data points based on their features or attributes. Some popular decision boundary algorithms include decision trees, random forests, logistic regression, and support vector machines.   One example of a decision boundary algorithm is the logistic regression algorithm. To determine the likelihood of a binary outcome (such as "yes" or "no"), a binary classification procedure known as logistic regression is utilized(yes/no, true/false). It creates a decision boundary by fitting a logistic function to the training data.   Let's consider the example of a dataset containing information about a bank's customers, including their age and credit score, as well as whether they have defaulted on a loan. We can use logistic r...

What is Reinforcement Learning Algorithm

Machine Learning  Reinforcement Learning Algorithms Reinforcement Learning Concepts Reinforcement learning is a type of machine learning where an agent learns to interact with an environment by taking actions and receiving rewards or punishments. Learning a policy that maximizes the cumulative reward across a series of actions is the aim of reinforcement learning. Two common reinforcement learning algorithms are Q-learning and Deep Q-Networks (DQNs). Q-learning r einforcement learning algorithm Q-learning is a model-free, off-policy reinforcement learning algorithm. In Q-learning, the agent learns an action-value function, called a Q-function, which estimates the expected cumulative reward for taking a particular action in a particular state. The Q-function can be represented as a lookup table or a neural network. The Q-function is updated using the Bellman equation: Q(s,a) = Q(s,a) + α(r + γmax(Q(s',a')) - Q(s,a)) where Q(s, a) is the Q-value for taking action an in stat...
