The travelling salesman problem(TSP) is a solution where a salesman has to start from one place and go to all other cities just once and then come back to their own place. TSP is all about finding the minimum distance path. The polynomial-time hardness is called NP Hard which defines the property of a class of problems. The subset sum is a simple example of NP hard problem. NP-hard − The class of problem which cannot be solved within a polynomial time is called NP-hard. Let’s take an example of five cities to understand how salesmen travel to each ... Read More

The program that trains the learning sequence of a machine is called the learning model of that machine. A machine learning model is a programmed pattern of training that makes conclusions from the dataset that is previously used in machine learning. There are different machine learning models which are divided into different factors, like the type of task given to the machine. Models in Machine Learning The process of algorithmic learning methods to find certain scenarios and give outputs is known as the machine learning model. A specific pattern or output is found from the dataset, while training is called ... Read More

What is Shattering a set of Points and VC Dimensions

Jay Singh
Updated on 25-Apr-2023 17:33:20
Shattering is a key notion in machine learning that refers to a classifier's capacity to accurately distinguish any arbitrary labeling of a group of points. Strictly speaking, a classifier breaks a collection of points if it can divide them into all viable binary categories. The greatest number of points that a classifier is capable of shattering is specified by the VC dimension, which measures a classifier's ability to classify data. For practitioners of machine learning, it is essential to comprehend the idea of shattering and the VC dimension. In this post, we will closely look at shattering a set points ... Read More

What is Bayes Theorem in Machine Learning

Updated on 25-Apr-2023 14:28:31
The Bayes Theorem, a cornerstone of probability theory, enables the computation of conditional probabilities. The idea behind the theorem is that opinions or previous knowledge change when new information comes to light. The Bayes Theorem has grown in significance in the area of machine learning because it enables the inclusion of previous information into statistical models, producing predictions that are more precise. Application areas for the Bayes Theorem in machine learning include spam detection, medical diagnosis, picture recognition, and natural language processing. Bayes Theorem has developed into a crucial tool for creating precise and effective machine learning models by offering ... Read More

Understanding Train and Split Criteria in Machine Learning

Jay Singh
Updated on 25-Apr-2023 14:31:16
In the field of machine learning, the train-test split is a straightforward yet effective method. In essence, it entails separating your dataset into two separate sets, one for training your model and the other for evaluating its correctness. The efficiency of your model's predictions in light of fresh data may be assessed using this method. You can evaluate how effectively a model generalizes and, consequently, how well it will perform in the real world by giving it a brand-new dataset that it has not been trained on. The train-test split essentially acts as a "reality check" for the capabilities of ... Read More

The effect on the coefficients in the logistic regression

Jay Singh
Updated on 25-Apr-2023 15:08:42
Statistically, the connection between a binary dependent variable and one or more independent variables may be modeled using logistic regression. It is frequently used in classification tasks in machine learning and data science applications, where the objective is to predict the class of a new observation based on its attributes. The coefficients linked to each independent variable in logistic regression are extremely important in deciding the model's result. In this blog article, we'll look at the logistic regression coefficients and how they affect the model's overall effectiveness. Understanding the Logistic Regression Coefficients It is crucial to comprehend what the logistic ... Read More

How to implement a gradient descent in Python to find a local minimum?

Jay Singh
Updated on 25-Apr-2023 13:21:22
Gradient descent is a prominent optimization approach in machine learning for minimizing a model's loss function. In layman's terms, it entails repeatedly changing the model's parameters until the ideal range of values is discovered that minimizes the loss function. The method operates by making tiny steps in the direction of the loss function's negative gradient, or, more specifically, the path of steepest descent. The learning rate, a hyperparameter that regulates the algorithm's trade-off between speed and accuracy, affects the size of the steps. Many machine learning methods, including linear regression, logistic regression, and neural networks, to mention a few, employ ... Read More
