Introduction Moment's big data period requires a dependable and effective approach to opting for important variables from datasets. With so numerous functions available, it can be delicate to identify which bone has the most impact on the target variable. opting for only the most important variables improves model performance, improves model interpretability, and reduces the threat of overfitting. This composition describes numerous ways to remove important variables from your dataset. We'll go through both basic statistical approaches like univariate feature selection and regularization, as well as more sophisticated techniques like PCA and feature importance ... Read More

Introduction Two well−liked machine learning techniques, KNN and k−means clustering, are employed for various tasks. Both methods employ the k parameter, but they are applied to distinct problems and work in different ways. During classification and regression problems, KNN is a supervised learning method, whereas k−means clustering is an unsupervised learning approach. We shall examine the main distinctions between KNN and k−means clustering in this article, including the learning style, task, input, distance calculation, output, application, and restrictions of each method. We can select the best algorithm for a task at hand and steer clear of typical ... Read More

Introduction Machine learning largely relies on classification models, and the accuracy of these models is a key performance indicator. It can be difficult to increase a classification model's accuracy since it depends on a number of variables, including data quality, model complexity, hyperparameters, and others. In this post, we'll look at a few methods for improving a classification model's precision. Ways to Increase Accuracy Data Preprocessing Each machine learning project must include data preprocessing since the model's performance may be greatly impacted by the quality of the training data. There are various processes in ... Read More

Introduction Financial fraud has become an increasingly common problem for banks and financial organizations throughout the world as technology advances. Money laundering, identity theft, and credit card fraud can all result in major financial losses as well as damage to a bank's image. As a result, banks must take proactive steps to prevent and detect fraudulent activity. Building a fraud detection model is one such method that can assist identify fraudulent transactions and flag them for further examination. In this article, we will examine the steps involved in creating a fraud detection model for a bank, starting with ... Read More

Introduction Mel Frequency Cepstral Coefficients (MFCCs) is a widely used feature extraction technique for audio processing, particularly in speech recognition applications. A logarithmic compression, a filter bank, and the discrete Fourier transform (DFT) of audio signals in brief time intervals are used to create MFCCs. You will have a thorough understanding of how to train MFCC using machine learning algorithms by the end of this article. What is an MFCC MFCC stands for Mel−Frequency Cepstral Coefficients. It is a widely used feature extraction technique in audio signal processing and speech recognition. The MFCC algorithm is based on the human ... Read More

Introduction Data science and machine learning are fast expanding professions, and having a graduate degree in these topics might provide you an advantage in the employment market. Yet, with so many applications accessible, it might be difficult to select the best one. The MS degree in CS (Machine Learning) from Georgia Tech and the MS degree in Data Science from NYU are two prominent possibilities. The curriculum at Georgia Tech is strongly focused on computer science and machine learning techniques and systems. The curriculum at NYU is more multidisciplinary, covering areas like as statistics, machine learning, data visualisation, and data ... Read More

Machine learning is a subset of artificial intelligence (AI) that enables machines to learn from data without being explicitly programmed. From predicting customer behavior to recognizing images and speech, it is a rapidly growing field. Adding machine learning to your toolkit can help you excel in many sectors such as finance, fraud detection, automobile, research, etc. Day 1-5: Basics of Machine Learning Before diving into its technical aspects, it is imperative to understand the fundamental concepts of machine learning. Learn about the types of machine learning, such as supervised, unsupervised, and reinforcement learning. Focus on key points, ... Read More

Machine learning is a rapidly expanding subset domain of the artificial intelligence field that has gained significant attention in recent years. It enables the systems to learn from data and improve their performance over time without having to be explicitly programmed or taught. Machine learning is now used in a variety of areas, like healthcare, banking, e-commerce, etc. It has evolved into a critical tool for many organisations to analyse and exploit data in order to improve operations, improve user experiences, and drive growth. Machine learning, with its tremendous potential, is set to change the way we live, work, ... Read More

Correlation is a statistical approach for determining the degree to which two variables are related. The Spearman's rank correlation coefficient, usually known as Spearman's rho, is a non-parametric correlation measure that assesses the monotony of two variables. It was named for its inventor, Charles Spearman, who created it in 1904. Assume we need to determine the age difference between two people. Spearman's rank coefficient can be used. There are two kinds of correlation: Parametric Correlation: It is known as a parametric correlation test because it assesses the linear dependency between two variables (x and y) ... Read More

In the realm of data analysis, understanding the relationships between variables is crucial. However, in some cases, these relationships can become too intertwined, leading to a phenomenon known as multicollinearity. Multicollinearity can pose challenges when interpreting the effects of individual variables in a statistical model. In this article, we will explore the concept of multicollinearity, its principal types, causes, and provide an example to illustrate its impact. In this article, we will explore the concept of multicollinearity in detail. We will delve into its principal types, examine the causes that give rise to multicollinearity in datasets, and provide ... Read More
