Study Notes
Neural Networks
- A neural network consists of neurons, which are linear functions with optional non-linear activations.
- A neuron's output is calculated as yi = Σ xj*wij + bi, where xi is the input, wij is the weight, and bi is the bias.
Deep Neural Networks
- A deep neural network is a neural network with multiple layers.
- Deeper neural networks have more layers, allowing for more complex representations of data.
Activations
- Activations are used for intermediate neurons to introduce non-linearity.
- Examples of activation functions include sigmoid, tanh, and ReLU.
Classifiers
- Classifiers are machine learning models that predict labels from features.
- Examples of classifiers include Support Vector Machines (SVM), Naïve Bayes, Logistic Regression, and Neural Networks.
- Deep Learning is a type of Neural Network.
Learning a Classifier
- The goal of learning a classifier is to predict labels from features.
- This can be visualized as finding a decision boundary in feature space.
- Examples of classifier learning algorithms include SVM (max margin hyperplane) and KNN (look at K neighbors and use their class).### Artificial Intelligence and Computer Vision Application Domains
