Study Notes
Machine Learning
Definition
Machine learning is a subset of Artificial Intelligence (AI) that enables machines to learn from data and make decisions or predictions without being explicitly programmed.
Types of Machine Learning
- Supervised Learning: The machine is trained on labeled data to learn the relationship between input and output.
- Unsupervised Learning: The machine is trained on unlabeled data to discover patterns or relationships.
- Reinforcement Learning: The machine learns by interacting with an environment and receiving feedback in the form of rewards or penalties.
Machine Learning Algorithms
- Linear Regression: A linear model that predicts a continuous output variable based on one or more input features.
- Decision Trees: A tree-based model that splits data into subsets based on features and predicts the outcome.
- Neural Networks: A model inspired by the human brain, composed of layers of interconnected nodes (neurons) that process inputs.
Computer Vision
Definition
Computer vision is a field of study that focuses on enabling machines to interpret and understand visual information from the world.
Applications of Computer Vision
- Image Classification: Machines classify images into predefined categories (e.g., objects, scenes, actions).
- Object Detection: Machines identify and locate objects within images or videos.
- Image Segmentation: Machines divide images into their constituent parts or objects.
Computer Vision Techniques
- Convolutional Neural Networks (CNNs): A type of neural network specifically designed for image and video processing.
- Image Filtering: Techniques used to enhance or preprocess images, such as blurring or edge detection.
- Feature Extraction: Methods used to extract relevant information from images, such as shape, color, or texture.
Challenges in Computer Vision
- Image Variability: Variations in lighting, pose, and occlusion can make it difficult for machines to interpret visual data.
- Noise and Distortion: Noise and distortion in images can affect the accuracy of computer vision algorithms.
- Contextual Understanding: Machines struggle to understand the context and meaning of visual data, requiring more advanced AI capabilities.
