Use a continuation piece

BOTIE

Match a starting vocabulary entry and a marked continuation, then retrieve their IDs. The ## marker belongs to the vocabulary key, not to the source spelling.

Examples, experiments and workspace controls
Live values

Connect a tool's inputs to see what it produces. You can try a branch before connecting it to Result.

Try your own inputs

Use a copy of the example to try your own data. Keep the problem's assumptions in mind, and predict the effect of a change before checking the output. You can also add another branch to compare two ways of doing the calculation.

Start at an output arrow, then click or drag to an input. Drag empty space to pan. Delete removes a selection. Ctrl/Cmd+Z undoes a change.
Context for this challenge

Match a starting vocabulary entry and a marked continuation, then retrieve their IDs. The ## marker belongs to the vocabulary key, not to the source spelling.

Botie can represent a word using an initial piece and a continuation entry. The continuation marker is part of the vocabulary convention, even though it does not appear in the source spelling.

Segment the word using the supplied WordPiece entries, then look up the resulting vocabulary keys.

Try a fresh construction

This clears this draft, including its undo history. Earlier successful attempts stay recorded. Build again without opening hints to record an independent attempt.

Stuck? Inspect a worked construction

The tools below form one possible solution. You can assemble it, follow its signals, and undo that change to return to your own construction.

Assumptions and test precision

This is a small construction problem. The lesson explains the assumptions and the parts of the full method that this example leaves out. Numerical tests allow a difference of 0.001. Lists and structures must also have the right shape.

A prefix needs two continuation pieces

This check uses the pieces from “Match a start piece and a marked continuation”.

BOTIE

Tokenise unhelpful using the supplied WordPiece vocabulary. Only the first piece starts a word; later pieces need continuation markers. Return the vocabulary IDs.

WordPiece vocabulary
{
  "un": 2,
  "##help": 5,
  "##ful": 9
}

Use a number, text, or an array matching the requested result. For a matrix, put each row in brackets. Saving your prediction runs your current construction on these inputs and checks the earlier examples too.

Build a construction in the workspace above first. This case will test those pieces.

Why would looking up ed instead of ##ed fail to follow this supplied vocabulary?

Vocabulary markers carry tokenizer-specific rules about where a piece may appear.
