Study Notes
ULMFiT Framework
- The ULMFiT framework was proposed by the research group to adapt pretrained LSTM models for various tasks.
Pretraining in ULMFiT
- The main objective of the pretraining step in ULMFiT is to learn a good initialization for the model's weights.
Domain Adaptation in ULMFiT
- The main objective of the domain adaptation step in ULMFiT is to adapt the pre-trained model to the target domain.
Fine-Tuning in ULMFiT
- The main objective of the fine-tuning step in ULMFiT is to adapt the model to the specific task at hand.
Language Modeling Approach
- BERT uses a masked language modeling approach, where some inputs are randomly replaced with a [MASK] token, and the model predicts the original token.
GPT Pretraining
- GPT was pretrained on the BooksCorpus and English Wikipedia datasets.
Transformer Architecture
- BERT uses the encoder part of the Transformer architecture.
- GPT uses the decoder part of the Transformer architecture.
Computer Vision
- Convolutional Neural Networks (CNNs) are commonly used in computer vision for transfer learning.
Pretraining in Computer Vision
- The purpose of pretraining in computer vision is to learn general features that can be applied to various tasks.
Advantage of Transfer Learning
- The main advantage of using transfer learning in computer vision is that it reduces the need for large amounts of labeled data.
Model Architecture Division
- In transfer learning, the model architecture is typically divided into a feature extractor and a task-specific classifier.
Fine-Tuning in Transfer Learning
- The purpose of fine-tuning in transfer learning is to adapt the pre-trained model to the specific task at hand.
Pretraining Datasets in Computer Vision
- Large datasets such as ImageNet are commonly used for pretraining in computer vision.
Transfer Learning vs Traditional Supervised Learning
- The difference between transfer learning and traditional supervised learning in computer vision is that transfer learning uses pre-trained models, while traditional supervised learning trains models from scratch.
