Evaluating machine learning models, especially for classification tasks, goes beyond measuring just accuracy. In real-world scenarios—such as fraud detection, medical diagnosis, or spam filtering—datasets are often imbalanced, making accuracy an unreliable metric. This is where the AUC-ROC Curve becomes essential. It provides a comprehensive view of a model’s ability to distinguish between classes across various … Read more
Search Algorithms in AI
Abhimanyu Saxena
Search algorithms form the backbone of problem-solving in artificial intelligence (AI). Whether it’s navigating a maze, planning a robot’s movement, or strategizing in a game, AI systems often need to explore various possibilities to reach a goal. This exploration is enabled by search algorithms. These algorithms simulate intelligent behavior by systematically examining sequences of decisions … Read more
