In this article you will learn about machine learning, image classification and how to use the googles teachable machine for training the models. Machine learning Machine learning is a subset of AI (artificial intelligence) which is used to develop the models and algorithms using which we can make our computers learn and make the decision without programming it explicitly. This is an effective way to teach machines to learn from the given data and improve the performance by time. Computers can learn the task and make predictions or find any pattern using data which shows the scenario about what we ... Read More

In this article we will learn about various methods using which we can find products of uneven size matrix columns. Working with matrices is very common for fields like data analysis, machine learning, so there can be situations where we have to find the matrix column product which can be a challenging task. Let’s see some examples for finding the uneven size matrix column product − Method 1: Using a Simple Loop In this method we will use the concept of simple nested loop and we will iterate through the matrix column and compute their products. Example def col_product_loop(mat): ... Read More

In this article, we'll examine a C++ procedure for ascendingly sorting an array of numerical string values. Sorting is a basic operation that entails organizing elements in a predetermined order. Because they are character-based strings that represent numbers, and these numerical strings provide a special set of challenges when it is related to sorting. The issue statement, a method and algorithm for solving it, a C++ implementation, a complexity reasoning of the provided approach, and a summary of the main points will all be covered. Problem Statement Consider a vector containing numerical strings, the aim is to arrange them in ... Read More

When dealing with string manipulation problems, it's common to encounter scenarios where we need to transform a given string into a specific pattern or format. One such problem is making a palindrome binary string with a certain number of '0's and '1's while replacing wildcard characters represented by '?'. In this article, we will explore an efficient algorithmic approach to solve this problem using C++. We'll discuss the problem statement, and its approach, and analyze the time and space complexity of the algorithm. Problem Statement Given a string consisting of '0's, '1's, and wildcard characters '?', we need to convert ... Read More

The analysis and manipulation of strings are fundamental operations in many applications of computer programming. Counting subsequences with the pattern "01" in a string formed by repetitively concatenating a given numeric string poses an interesting challenge. The primary question is determining the total count of such subsequences in the resulting string. This article discusses a useful C++ approach to solve this issue successfully and offers a solid answer to deal with this particular work. Concept of Subsequence A subsequence is a sequence of characters that is derived from some other sequence by eliminating zero or more characters without altering the ... Read More

In mathematics, there are several types of numeric values such as integers (having no fractional part), floating point numbers (having fractional parts separated by a decimal), and more. In some data analysis and other computational applications, we are given floating point numbers that contain a decimal part, i.e., digits after a decimal point. But we require only integers. Hence, if you are using MATLAB as your data processing tool, then you can use it to remove decimals present in the given number. This tutorial is primarily meant for explaining the different methods of removing decimals from a given number using ... Read More

In MATLAB, reading a text file backwards involves reversing the order of the lines written in the file. We can use MATLAB to reverse the order and read the text file backwards. For this, MATLAB provides various methods using different functions and algorithms. In this tutorial, I will explain the commonly used methods to read a text file backward using MATLAB. Create a Text File in MATLAB In MATLAB, we can create a text file using the built-in functions "fopen" and "fprintf". Example The following example demonstrates the process of creating a text in MATLAB. % MATLAB code to ... Read More
