Machine Learning And Deep Learning - Fundamentals And Applications [Introduction Video]
Introduction to Machine Learning and Deep Learning
Course Overview
- Dr. MK Bhuya introduces the course on machine learning and deep learning, focusing on fundamental concepts and applications.
- The objective is to familiarize students with broad areas of machine learning and deep learning, emphasizing the design of machines that learn from examples.
- Importance of understanding mathematical concepts for grasping machine learning and deep learning principles.
Definitions
- Artificial Intelligence (AI) is defined as programs capable of learning and reasoning like humans.
- Machine Learning (ML) is a subset of AI that allows algorithms to learn without explicit programming, focusing on statistical methods and soft computing techniques.
Key Concepts in Machine Learning
Traditional Programming vs. Machine Learning
- Traditional programming requires input data along with a program to produce outputs; ML reverses this by using data to generate programs or algorithms.
Types of Learning
- Supervised Learning: Involves training data with known desired outputs.
- Unsupervised Learning: Uses training data without known outputs, often for clustering or association tasks.
- Semi-Supervised Learning: Combines small amounts of labeled data with large amounts of unlabeled data; useful in fields like medical image analysis due to limited labeled datasets.
- Reinforcement Learning: Focuses on maximizing cumulative rewards through sequences of actions rather than single actions.
Applications of Machine Learning
Real-world Applications
- Examples include species recognition, speech signal processing, biometrics (fingerprint identification), optical character recognition, DNA sequence identification, biomedical image analysis, digit recognition, and molecular classification.
Broader Application Areas
- Other applications span web search, computational biology, finance, e-commerce, space exploration, robotics, information extraction from social networks, debugging software.
