Study Notes
Voter Registration and Legislative Changes
- Since 2009, numerous American governments have enacted laws that complicate voter registration and voting processes.
Attention Mechanism in Neural Networks
- Attention mechanisms help model long-distance dependencies in sequences, crucial for tasks requiring contextual understanding.
- Layers in models like transformers benefit from attention heads that focus on important terms, such as the verb "making," enhancing comprehension.
Positional Encoding
- Sinusoidal positional encoding is utilized to represent different positions in sequences, facilitating learning of relative positions among inputs.
- The encoding wavelengths range geometrically, which aids models in extrapolating to lengthier sequences beyond the training set.
Self-Attention Mechanism
- Self-attention (or intra-attention) relates various positions within a single sequence for comprehensive representation.
- Effective for various language tasks, including reading comprehension, summarization, and sentence representation.
Model Comparison
- The efficiency of self-attention is measured against recurrent and convolutional layers in terms of computational complexity and ability to learn long-range dependencies.
- Shorter path lengths in self-attention reduce the difficulty of learning dependencies by minimizing traversal distance in the network.
Transformer Architecture
- The Transformer is distinguished by its pure reliance on self-attention for input-output representation, without the use of RNNs or convolutions.
- Characterized by an encoder-decoder structure where the encoder converts input sequences into continuous representations, and the decoder generates output symbols in an auto-regressive manner.
