Study Notes
Meta-Learning and Transfer Learning
- Meta-learning in MAML involves preserving the norm of activations and gradients when propagated through the network
- Transfer learning can be used to perform tasks that are similar to each other, such as reading zip codes and digits
Normalization Layers and Transfer Learning
- Normalization techniques are used to preserve the norm of activations and gradients
- Transfer learning involves using a pre-trained model on a new task, and can be used to perform tasks that are similar to each other
CNN Architectures
- LeNet-5 (1998) is an example of a CNN architecture, consisting of multiple convolutional and subsampling layers
- The architecture of LeNet-5 includes:
- Input layer: 32x32
- C1: feature maps 6@28x28
- C3: feature maps 16@10x10
- S4: feature maps 16@5x5
- S2: feature maps 6@14x14
- C5: layer
- F6: layer 120
- Output layer: 10
Image Recognition Tasks
- Image classification involves assigning a single label to the entire image
- Image recognition tasks include:
- Semantic Segmentation
- Object Detection
- Instance Segmentation
- Panoptic Segmentation
Semantic Segmentation
- Semantic segmentation involves assigning a class label to each pixel in the image
- The goal is to consider the full scene context, including object classes, location, and shape of all scene elements including the background
- A fully convolutional approach can be used to predict classes for all pixels simultaneously, resulting in superior performance
Detection and Segmentation
- Object detection involves assigning a bounding box to each object in the image
- Instance segmentation involves assigning a unique label to each instance of an object in the image
- Panoptic segmentation involves assigning a class label to each pixel in the image, and differentiating between different instances of the same class
