Module1 Generative AI (GenAI) is the latest subtype of AI that broadly describes  Machine Learning (ML)  models or algorithms. Difference Between Traditional AI and Generative AI Traditional AI Generative AI      AI is used to create intelligent systems that can perform those tasks which generally require human intelligence.      It generates new text, audio, video, or any other type of content by learning patterns from existing training data.      The purpose of AI algorithms or models are to mimic human intelligence across wide range of applications.      The purpose of generative AI algorithms or models is to generate new data having similar characteristics as data from the original dataset. Overview of Generative Adversarial Network      GAN stands for Generative Adversarial Network, and it is a class of artificial intelligence algorithms used in machine learning and deep learning for generating dat...

Use Case Diagram for Bank ATM System      Automated Teller Machine (ATM)   also known as ABM (Automated Banking Machine) is a banking system. This banking system allows customers or users to have access to financial transactions. These transactions can be done in public space without any need for a clerk, cashier, or bank teller. Working and description of the ATM can be explained with the help of the   Use Case Diagram . Some scenarios of the system are as follows. Step-1: Customer Authentication 1. The user is authenticated when enters the plastic ATM card in a Bank ATM. 2. Then enters the user name and PIN (Personal Identification Number). 3. For every ATM transaction, a Customer Authentication use case is required and essential. So, it is shown as include relationship. Step-2: Bank ATM System 1. User checks the bank balance as well as also demands the mini statement about the bank balance if they want.  2. Then the user withdraws the money as per their ...

  What is Data Visualization? Data visualization translates complex data sets into visual formats that are easier for the human brain to comprehend. This can include a variety of visual tools such as: Charts : Bar charts, line charts, pie charts, etc. Graphs : Scatter plots, histograms, etc. Maps : Geographic maps, heat maps, etc. Dashboards : Interactive platforms that combine multiple visualizations. The primary goal of data visualization is to make data more accessible and easier to interpret, allowing users to identify patterns, trends, and outliers quickly.  Types of Data for Visualization Data visualization is categorized into the following categories: Numerical Data  Categorical Data Let’s understand the visualization of data via a diagram with its all categories. Why is Data Visualization Important? Let’s take an example. Suppose you compile visu...

Data Structures and Algorithms (DSA) Interview Questions

  Data Structures and Algorithms (DSA) Interview Questions Data Structures and Algorithms (DSA) are one of the most important topics for technical interviews. Strong knowledge of DSA helps in improving problem-solving skills and cracking coding interviews. 🔹 What is Data Structure? A Data Structure is a way of organizing and storing data efficiently so that it can be accessed and modified easily. Examples: Array Linked List Stack Queue Tree Graph 🔹 What is an Algorithm? An Algorithm is a step-by-step procedure to solve a problem. Example: Sorting a list of numbers using a specific method. 🔹 Common DSA Interview Questions 1. What is the difference between Array and Linked List? Array Linked List Fixed size Dynamic size Fast access Slow access Uses contiguous memory Uses non-contiguous memory 2. What is a Stack? A Stack follows LIFO (Last In First Out) principle. Example: stack = [] stack.append(10) stack.append(20) print(stack.pop()) 3. What is a Queue? A Queue follows FIFO (Fir...
