Linear correlation: The correlation is linear if the ratio of change is constant. [3] If we double X, Y will be doubled as well. Nonlinear correlation: If the ratio of change is not constant, we are facing nonl
Pandas is a special tool which allows us to perform complex manipulations of data effectively and efficiently. Inside pandas, we mostly deal with a dataset in the form of DataFrame.DataFramesare 2-dimensional data structure in pandas. DataFrames consists of rows, columns and the data. Pandas pr...
Gradient boosting is a highly robust technique for developing predictive models. It applies to several risk functions and optimizes the accuracy of the model’s prediction. It also resolves multicollinearity problems where the correlations among the predictor variables are high. Gradient boosting machines...
Python is a versatile and widely-used programming language that has become a popular tool for data analysis, offering extensive libraries such as Pandas, NumPy, and Matplotlib that enable you to efficiently manipulate, analyze, and visualize data, making it a robust choice for a wide range of ...
Supervised learningsupplies algorithms with labeled training data and defines which variables the algorithm should assess for correlations. Both the input and output of the algorithm are specified. Initially, most ML algorithms used supervised learning, but unsupervised approaches are gaining populari...

Association rule mining identifies relationships and correlations between different variables within a dataset. For example, it can uncover patterns such as “if a customer buys a particular product, they are likely to purchase another related product.” This information can help businesses make data-...
Randomness ensures that individual trees have low correlations with each other, which reduces the risk of bias. The presence of a large number of trees also reduces the problem of overfitting, which occurs when a model incorporates too much “noise” in the training data and makes poor decision...
Technique #1: How to find duplicate values in SQL table Identifyingduplicate valuesin a database is essential for maintaining data integrity and accuracy. To find duplicate values in an SQL table, you can utilize the “GROUP BY” and “HAVING” clauses along with aggregate functions. ...
Data analysis tools involve software that can be used for big data analytics, where relevant insights, correlations and patterns are identified within given data. Big Data Tools Big data tools refer to any data platform, database, business intelligence tool or application where large data sets are...
