What is Agile methodology, and how does it improve the software development process compared to traditional Waterfall methodology?
Supervised and unsupervised learning are two primary methods in machine learning. Supervised learning involves training a model on labeled data. This means the model learns to map inputs to desired outputs. For example, predicting house prices based on features like size and location. Common algoritRead more
Supervised and unsupervised learning are two primary methods in machine learning.
Supervised learning involves training a model on labeled data. This means the model learns to map inputs to desired outputs. For example, predicting house prices based on features like size and location. Common algorithms include linear regression, logistic regression, and decision trees.
Unsupervised learning deals with unlabeled data. The goal is to find patterns or structures within the data. Clustering and association rule mining are examples. Common algorithms are k-means clustering for grouping data points and Apriori for discovering relationships between items.
Essentially, supervised learning is like a teacher providing correct answers, while unsupervised learning is like exploring a dataset without guidance.

Key Concepts of Agile Methodology
How Agile Improves the Software Development Process
Comparison to Waterfall Methodology
Sequential Phases: Development is divided into distinct phases (requirements, design, implementation, testing, deployment), each of which must be completed before moving to the next.
Fixed Requirements: Requirements are gathered at the beginning and are expected to remain unchanged.
Late Testing: Testing occurs only after the implementation phase, potentially leading to late discovery of defects.
Limited Customer Involvement: Customers are typically involved only at the beginning (requirements phase) and end (delivery) of the project.
Iterative Phases: Development is divided into short, iterative cycles with continuous feedback and refinement.
Flexible Requirements: Requirements can evolve based on ongoing feedback and changes in the business environment.
Continuous Testing: Testing is integrated into each iteration, ensuring early and frequent validation of the software.
Continuous Customer Involvement: Customers are involved throughout the project, providing feedback at the end of each iteration.
In summary, Agile methodology offers a more flexible, collaborative, and customer-focused approach to software development compared to the traditional Waterfall model, leading to faster delivery, higher quality, and greater customer satisfaction.
