Kutsvaga kweBeam
Beam search is a decoding algorithm that retains a fixed number of high-scoring partial sequences at each step.

Pfupiso
It is used in sequence generation tasks, with results shaped by model scores and any normalization or penalties.
Kudzika Kwakadzika
At each decoding step, beam search expands the current partial candidates and retains the top-scoring continuations. A wider beam explores more options but increases search cost and does not necessarily improve perceived quality. GNMT uses length normalization to mitigate short-output bias and a coverage penalty to encourage source-word coverage in translation. Diverse beam search modifies group selection to reduce redundant candidates.
Kuitwa muNyika yeChokwadi
A beam of width k keeps up to k partial sequences rather than only one greedy continuation.
GNMT used length normalization and a coverage penalty in its translation system.
Diverse beam search adds a penalty to reduce overlap among candidate sequences from beam groups.
For open-ended text, compare beam outputs with sampling because likelihood-ranked outputs can be repetitive or bland in the evaluated settings.
Ramangwana Rekutsvaga Beam
Select decoding criteria for the task and measure both search cost and output quality. For translation, report source coverage and reference-based metrics; for open-ended generation, include human evaluation where appropriate. The cited sources describe particular methods and experiments rather than a single universally best beam configuration.
