Study Notes
Fraud Detection
- Considered a classification problem, specifically binary classification.
Probability Distribution
- Binary classification utilizes the Bernoulli distribution for modeling two possible outcomes.
Types of Learning
- Reinforcement learning, supervised learning, and unsupervised learning are common types; non-parametric learning is not typically classified this way.
Facial Expressions Algorithm
- Convolutional neural networks (CNNs) are used to learn facial identities and their corresponding expressions.
Batch Training
- Online learning models are trained with data in a single batch, adjusting continuously with incoming data.
Training Data
- The term for data that machine learning algorithms use to build a model is "training data".
Artificial Intelligence Techniques
- Machine Learning is a subset of Artificial Intelligence that focuses on enabling systems to learn from data.
Logistic Regression Purpose
- Used to model binary dependent variables and estimate probabilities of outcomes.
Equation Y=MX+B
- In this equation, Y represents the dependent variable or the outcome we are predicting.
Continuous Outcome Prediction
- Regression tasks involve predicting continuous outcomes, such as price or temperature.
Supervised vs. Unsupervised Learning
- Supervised learning requires labeled data for training while unsupervised learning analyzes data without labels.
Pattern Finding Technique
- Clustering techniques primarily focus on identifying patterns or structures within non-labeled data.
Decision Tree Model Applications
- Can be used for classification problems, such as categorizing items, and regression problems for estimating numerical outcomes.
AI and Human Intelligence
- AI is designed to mimic certain aspects of human intelligence, simulating reasoning and problem-solving.
Machine Learning Self-Learning
- Machine Learning algorithms can adjust and learn from data autonomously, refining their predictions over time.
Cost Function Usage
- Mean Squared Error (MSE) and Cross-Entropy Loss are common cost functions applicable for both classification and regression tasks.
Dice Loss Function
- Mainly used in image segmentation tasks, particularly in medical imaging, to measure the similarity between predicted and actual masks.
Spam Email Detection
- Identifying spam mail is classified as a supervised learning problem, where labeled examples are used for training.
