About hello ML

Computer Science and programming articles. We do not sell courses.

Who We Are

hello ML is a community-driven blog where contributors share articles on machine learning, data structures, algorithms, problem solving, C programming, Python programming, and web development. Every piece is written by programmers and computer science enthusiasts who want to help others learn.

The site was active throughout 2021, publishing tutorials, conceptual deep-dives, and LeetCode problem solutions. Contributors included Ajit Singh, Hrushikesh, Aradhit, Dharani, Thuyen_Pham, Anik Chatterjee, Preeti Bhowmick, Aindree Chatterjee, and Swaminathan Ayyappan, among others.

We do not sell courses. Everything published here is freely available for anyone who wants to read and learn.

Knowledge grows when it's shared — that's the idea behind hello ML.

What We Cover

  • Machine Learning — error analysis, decision trees, logistic regression, AdaBoost, Hive, and ID3.
  • Data Structures — binary search trees, queues, AVL trees, linked lists, and ternary search trees.
  • Algorithms — heap sort, searching, sorting, and complexity analysis.
  • Problem Solving — LeetCode solutions with step-by-step explanations in Java and C++.
  • C Programming — tutorials and articles focused on the C language.
  • Python Programming — data visualization with Matplotlib, Seaborn, and Pandas, plus exception handling.
  • Web Dev — HTML fundamentals including styles, headings, and paragraphs.
