Study Notes
Limitations and Advantages of Models
- Decision tree models are limited by overfitting and lack of robustness to outliers
- Ensemble models like Bagging and Boosting have an advantage of improving the accuracy and robustness of decision trees
Harvard Course CS109A Introduction to Data Science
- Slides from the course can be found online
- The course is referenced for the lecture on Introduction to Data Science, which cites a particular book
Introduction to Machine Learning Lecture
- The main focus of the lecture by Prof. Alex Ihler is on Ensembles: Bagging, Gradient Boosting, and AdaBoost
- The lecture covers the concepts of Bagging, Gradient Boosting, and AdaBoost in machine learning
Artificial Neural Networks (ANN)
- The primary metaphor used to describe ANN is the human brain
- ANN has potential application areas in computer vision, natural language processing, and speech recognition
- One remarkable ability of deep learning is that it can learn complex patterns and representations from data
- The main difference between a deep network and a shallow network is the number of layers, with deep networks having more layers
- Biological neurons are characterized by having dendrites, cell body, and axon, but the concept of "weight" is not mentioned as a characteristic of biological neurons in the context of ANN
