Introduction A heat map, is a graphical representation of data in which each value in a matrix is assigned a unique colour. The primary purpose of heat maps is to increase the accuracy of the visualization of the total number of places and events included within a dataset, as well as the accuracy with which they direct viewers' attention to the most important aspects of data visualizations. Heat maps, which rely on colour to communicate values, are most commonly used to offer a more holistic picture of numerical values. This is due to the fact that heat maps rely on ... Read More

Introduction Animated pictures are a sequence of static images that are automatically played to display relevant material in a continuous and dynamic manner, and they have the benefit of being smaller than videos. Additionally, many online and mobile applications enable animated images in the same manner that they support static photos, although they do not always permit the upload of movies. In this situation, animated pictures can be really helpful. Clearly, there are several other reasons why animated graphics are preferable. Sometimes, combining similar or unrelated photos is simply for fun. In this article, we would learn the steps to ... Read More

Introduction The ratio of accurate predictions to inaccurate predictions is plotted in a matrix known as a confusion matrix. This would refer to the ratio of true negatives and true positives (right predictions) to false negatives and false positives for a binary classifier (incorrect predictions). After data cleaning, preprocessing, and parsing, the first thing we do is feed the data to an efficient model, which naturally produces results in probabilities. Hold on though! But how do we assess the performance of our model? Higher performance, better effectiveness—exactly that's what we want. And here’s when the Confusion matrix comes into ... Read More

Numpy is an open-source library in Python used for numerical computing, scientific computing, data analysis, and machine learning applications. This library has powerful array methods and tools to perform vector and matrix operations. You must install the NumPy module manually since it is not a component of the default Python library. The Python package manager pip can be used to accomplish this by executing the following command − pip install numpy We will use NumPy’s busday_count() function to calculate the required count of weekdays. This will calculate the number of business days (Monday to Friday) between 2 specific dates. ... Read More

Numpy is often used along with packages such as SciPy and matplotlib in python. Additionally, arrays in Numpy are faster compared to lists in Python due to which this module is extensively used for complex mathematical algorithms and problems. It has various functions, and methods, to make our task easy and simple for matrix operations. In Numpy arrays there are two types of array − Single Dimensional Array Multi-Dimensional Array Single Dimensional Array (1D array) The datatypes of the elements stored in the array are - strings, integers, boolean or floating points. These arrays are called single or ... Read More

Python users frequently work with files, particularly when altering, reading, or writing data to files. However, identifying a file's path is necessary before performing any operation on it. Simply said, a file's path refers to the system location or directory where it is kept. There are four major types of methods to use to find the path to the given file in Python − Pathlib Module OS Module os.path.join() method os.getcwd() method Approach 1: Using the Pathlib Module The pathlib module in Python makes everything very feasible and efficient to make file paths. absolute() − An absolute path ...

The well-known open-source Python library NumPy is used for numerical computing. Large, multi-dimensional arrays and matrices are supported, along with a sizable number of sophisticated mathematical operations that can be used to work effectively on these arrays. When working with NumPy arrays, finding the maximum and minimum elements is often necessary. Method 1:Using max() and min() Functions The following code demonstrates creating an array of integers. We then use the max() and min() functions to find the highest and lowest value elements in the array, respectively. Algorithm Import the desired Numpy library. Create a 1D numpy array with integer ... Read More
