Study Notes
Machine Learning
-
Definition: A subset of artificial intelligence that uses algorithms to analyze data, learn from it, and make predictions or decisions without being explicitly programmed.
-
Types of Machine Learning:
-
Supervised Learning:
- Uses labeled data for training.
- The model learns to map inputs to outputs based on examples.
- Common algorithms: Linear Regression, Decision Trees, Support Vector Machines (SVM), Neural Networks.
-
Unsupervised Learning:
- Uses unlabeled data.
- The model identifies patterns or groupings within the data.
- Common techniques: Clustering (e.g., K-Means, Hierarchical), Dimensionality Reduction (e.g., PCA).
-
Semi-Supervised Learning:
- Combines both labeled and unlabeled data.
- Useful when labeling data is expensive or time-consuming.
-
Reinforcement Learning:
- Based on a reward system.
- The model learns by taking actions in an environment to maximize cumulative reward.
- Commonly used in robotics and game playing.
-
-
Key Concepts:
- Training: The process of feeding data to a model to learn patterns.
- Testing: Validating the model's performance on unseen data.
- Overfitting: When a model learns noise in the training data rather than the underlying pattern, reducing its performance on new data.
- Underfitting: When a model is too simple to capture the underlying trend of the data.
-
Common Applications:
- Image and speech recognition.
- Natural language processing (NLP).
- Recommendation systems (e.g., Netflix, Amazon).
- Fraud detection and predictive maintenance.
-
Challenges:
- Data quality and availability.
- Computational resources required for processing large datasets.
- Interpretability of complex models, especially deep learning models.
-
Popular Tools and Frameworks:
- Libraries: TensorFlow, PyTorch, Scikit-Learn, Keras.
- Platforms: Google Cloud AI, AWS Machine Learning, Microsoft Azure Machine Learning.
-
Future Trends:
- Increased focus on ethical AI and bias reduction.
- Growth in automated machine learning (AutoML) tools.
- Integration of machine learning with other technologies like IoT and edge computing.
Machine Learning Overview
- A subset of artificial intelligence employing algorithms to analyze data for learning and prediction without explicit programming.
Types of Machine Learning
-
Supervised Learning:
- Utilizes labeled datasets for training, mapping inputs to outputs based on provided examples.
- Common algorithms include Linear Regression, Decision Trees, Support Vector Machines (SVM), and Neural Networks.
-
Unsupervised Learning:
- Operates on unlabeled data, identifying patterns or groupings.
- Techniques used are Clustering (e.g., K-Means, Hierarchical) and Dimensionality Reduction (e.g., PCA).
-
Semi-Supervised Learning:
- Mixes labeled and unlabeled data, beneficial when labeling is costly or time-intensive.
