Introduction This tutorial deals with the problem of finding the defanged version of the Internet Protocol Address. The Internet Protocol Address or IP Address is an individual numerical address of a device connected to or using the Internet. It is unique for every internet-connected device. It consists of numbers separated by the period (dot). An example would be 191.0.1.2. Defanged Version of Internet Protocol means replacing the periods (dot.) with other characters so that it is not treated as a valid IP address. For defanging the Internet Protocol Address we use [.] instead of periods ( dot .) The Internet ... Read More

Decryption or decrypt a string is the process used to protect confidential and sensitive data from hackers. It converts encrypted data or text into its original form. Encryption is the process of converting plain text into an unreadable and non-understandable cipher text format so that hackers cannot understand it. These processes are interrelated and involve various algorithms for processing. We decrypt the string according to the following algorithm. If the string length is odd. For odd index values append alphabets from the back of the string and for even index values append alphabets from the front of the input ... Read More

Introduction Encoding means converting the text into some form of representation, and decoding is the process of converting the encoded text into its original form. Encoding and decoding are two interrelated techniques for transferring information from one form to another. In this tutorial, we implement an approach to decode the string which is encoded with the given algorithm that finds the decoded string using an encoded string encoded with some algorithm. The string is encoded using the following concept − For example string = India Encoded string = dniIa In the string "India", the middle character is 'd', ... Read More

Introduction In this tutorial, we discuss the problem of counting the substrings from a given string with the sum of weights at most K. To implement the problem statement we consider a string S to generate substrings and some value for k. The character weights are predefined integer values and we consider some value of K like 2, 3 or anything. We count only those substrings whose total weight is equal to the value of K. The weights of the characters are defined in two different ways − When the weights are defined for a string in any order. ... Read More

Introduction In this tutorial, we will check if an input string can be formed using characters in the same row of the Qwerty keypad. The task is to check whether a given string exists in a single row of the Qwerty keypad. To determine whether a string can be printed with the same row of the Qwerty keypad, all characters should be found in the same row. We implement an approach using set and unordered_set to solve this task. The characters of different rows are stored in different sets or unordered_sets. Compare the string characters to each stored row value. ... Read More

Introduction In this tutorial, we implement an approach to check substring is palindrome by replacing its K characters for Q queries. Palindromes are words that read the same in both directions. When you read a palindromic word from a forward or backward direction, it sounds the same. For example, madam, refer. Here, Q queries are a numeric array containing the starting index, ending index, and value of K. The starting and ending index values for the input string are used to select only those characters that lie between these starting and ending index values (both values are inclusive). For the ...

Introduction In machine learning, Pywedge is a powerful library for creating dynamic graphs. Here is a rundown of what you can do with Pywedge and some of its features. In addition, the benefits of using Pywedge for interactive charting are highlighted, such as the program's ease of use and its ability to enhance data visualization. Installing Pywedge Requirements Make sure your computer fulfills these specifications before installing Pywedge and using it for interactive charting in ML − The Pywedge package requires Python 3.6 or later. Necessary external programs (like Pandas and Matplotlib) Installation Steps The following are the ... Read More

Automating the best machine learning pipelines has become extremely important for data scientists. TPOT (Tree-based Pipeline Optimization Tool) is an (excellent/very unusual) machine learning library that eliminates the need for manual and time-using/eating/drinking tasks like feature engineering, computer code-related selection, and hyperparameter tuning. Some key Points of TPOT are as Follows Simplifying Pipeline Optimization With TPOT Traditional machine learning workflows often involve wide-stretching transmission experimentation to find the weightier model. TPOT simplifies this process by employing genetic programming, an evolutionary algorithm, to automatically explore a vast space of potential pipelines and intelligently identify the most promising ones. Customization and Flexibility ... Read More

Understanding Neural Networks In the context of neural networks, the goal is to find the optimal set of weights and biases that minimize the difference between the predicted outputs of the network and the true outputs. Optimization Gradient descent optimization works by iteratively updating the network parameters in the opposite direction of the gradient of the loss function with respect to those parameters. The gradient points in the direction of the steepest increase in the loss function, so by moving in the opposite direction, the algorithm can gradually converge toward the minimum of the loss function. There are variegated variants ... Read More
