CLS Token as a Start Symbol in Encoder Pre-training
In encoder pre-training and related tasks, the special token is conventionally used as the start symbol for an input sequence. It is typically the first token, denoted as , and serves as a generic start-of-sequence marker.

Learn After
A researcher is preparing the sentence 'Neural networks learn patterns' for input into a sequence model. The model's design specifies that a special token must be placed at the very beginning of every input sequence to act as a start-of-sequence marker. Given this requirement, how should the researcher format the tokenized input?
Analyzing a Preprocessing Step
When preparing an input sequence for certain neural network architectures, a special token is conventionally placed at the very beginning to serve as a start-of-sequence marker. This token is denoted as ____.
