Python Scikit-learn provides us make_regression() function with the help of which we can generate a random regression problem. In this tutorial, we will learn to generate random regression problems and random regression problems with sparse uncorrelated design. Random Regression Problem To generate a random regression problem using Python Scikit-learn, we can follow the below given steps − Step 1 − Import the libraries sklearn.datasets.make_regression and matplotlib which are necessary to execute the program. Step 2 − Provide the number of samples and other parameters. Step 3 − Use matplotlib library to set the size and style of the output figure. Step 4 − ... Read More
Scikit-learn provides us make_classification() function with the help of which we can plot randomly generated classification datasets with different numbers of informative features, clusters per class and classes. In this tutorial, we will learn how to generate and plot classification dataset using Python Scikit-learn. Dataset with One Informative Feature and One Cluster per Class To generate and plot classification dataset with one informative feature and one cluster, we can take the below given steps − Step 1 − Import the libraries sklearn.datasets.make_classification and matplotlib which are necessary to execute the program. Step 2 − Create data points namely X and y ... Read More
In this tutorial, we will learn how to generate an array with a constant block diagonal structure and with a block checkerboard structure for bi-clustering using Python Scikit-learn (Sklearn). Generating an Array with a Constant Block Diagonal Structure To generate an array with constant block diagonal structure for biclustering, we can take the following steps − Step 1 − Import sklearn.datasets.make_biclusters and matplotlib. Step 2 − Set the figure size Step 3 − Create data points namely data, row, and column. Step 4 − Create a plotter to show the array with constant block diagonal structure. Step 5 − Provide ...

In this tutorial, we will learn how to create a sample dataset using Python Scikit-learn. There are various built-in scikit-learn datasets which we can use easily for our ML model but sometimes we need some toy dataset. For this purpose, scikit-learn python library provides us a great sample dataset generator. Creating Sample Blob Dataset using Scikit-Learn For creating sample blob dataset, we need to import sklearn.datsets.make_blobs which is very fast and easy to use. Example In the below given example, let’s see how we can use this library to create sample blob dataset. # Importing libraries from sklearn.datasets import make_blobs ... Read More
Scikit-learn, also known as Sklearn, is the most useful and robust open-source Python library that implements machine learning and statistical modeling algorithms including classification, regression, clustering, and dimensionality reduction using a unified interface. Scikit-learn library is written in Python and is built upon other Python packages such as NumPy (Numerical Python), and SciPy (Scientific Python). Installing Scikit-learn on Windows using pip To install Scikit-learn on Windows, follow the steps given below − Step1-Make Sure Python and pip is preinstalled Open the command prompt on your system and type the following commands to check whether Python and pip is installed or ...

Tortoises and Turtles both belong to class Reptilia of the order Testudines of Animalia kingdom. The word "Testudine" is derived from a Latin word, ‘Testa’, which means shell. Both, tortoises, and turtles have shells on their back to protect them from predators and various threats. They both lay eggs into the burrows. They both apparently look similar, but they have distinctive anatomical features as well as different habitat and behavior. They have been existing on the Earth since 200 million years. Read through this article to find out how turtles are different from tortoises. What is a Tortoise? Tortoise is ... Read More
There are various landforms on Earth’s surface such as rocks, cliffs, seashores, mountains, valleys, plateaus, and volcanic cones. The shape of these landforms continuously undergoes changes as they degrade due the exposure to changing environment, wind, ice, water, or any human activities. In Geology, the two terms are used to depict degradation of the landforms: Erosion and Weathering. Read through this article to understand the terms "Erosion" and "Weathering", and how they are different from each other. What is Erosion? Erosion is the process of breaking down rock particles and transporting those particles elsewhere thereby gradually changing the topography of ... Read More
There are mainly four big cats in the world: Jaguar, Leopard, Lion, Snow Leopard, and Tiger. All big cats roar and no animal can hunt them. Cheetah, Cougar, Lynx, Snow Leopard also belong to Family Felidae, Subfamily Felinae (a group of small to mid-size cats including bigger cats as Cheetah and Cougar), though they don’t roar. Among these cats, Tiger and Snow Leopard are related closely whereas Lion, Leopard, and Jaguar are related closely. At a quick glance, one may find Cheetah and Leopards the same in appearance but there are different in several ways. Please go through this article ... Read More
Amphibians and Reptiles belong to the class Amphibia of kingdom Animalia. They both are vertebrates and cold-blooded. They are ectotherms, means they are responsible to control their body temperature by relying upon external environment. They have extraordinary eyesight which helps them to hunt their prey. There are around 7000 species Amphibians and 10, 000 species of reptiles found all over the world. Amphibians and Reptiles both have been living on Earth since more than 300 million years. Despite these similarities, they have some differences in their appearance and life forms. Go through this article to understand how exactly Amphibians differ ... Read More
An up/down chart is one of the frequently used charts in Excel to compare the investments and their returns by a company. The creation of the up/down bars to the lines chart in Excel is a complex process, but in this tutorial, we will show how you can do it in a simple manner. How to Add Up/Down Bars to a Line Chart in Excel? Let us see an example to understand how you can add up/down bars to a line chart in Excel. Step 1 First, we need to create a line chart in Excel before adding up down ... Read More
