Résumé
Confidence is a model score used for selection, not a guarantee that a token is correct.
Plongeur bu xóot
MaskGIT (Masked Generative Image Transformer), from Google in 2022, rethinks how token-based image models decode. Earlier transformers such as VQGAN generate tokens autoregressively, one at a time in raster order. MaskGIT instead trains with a masked modeling objective like BERT: random subsets of image tokens are hidden and the model learns to predict them simultaneously using bidirectional attention. At generation time it starts from a masked grid and decodes over a configured number of refinement iterations; the original paper reports examples using roughly 8 to 12 steps, but the count depends on the setup rather than defining the algorithm. Each step predicts masked tokens, keeps selected high-confidence predictions, and re-masks other positions. Confidence ranks candidates for the next iteration; it does not prove a prediction is correct.

What is MaskGIT Parallel Token Decoding?
MaskGIT generates images by predicting many tokens at once and selecting high-confidence predictions for subsequent refinement, replacing left-to-right generation with parallel iterations. Confidence is a model score used for selection, not a guarantee that a token is correct.

Ci diiru defar, ban token la MaskGIT di def ci iteration bu nekk?
At each iteration, MaskGIT retains the predictions with the highest model confidence and re-masks other positions. Confidence is a ranking signal for selecting tokens, not proof that each selected token is correct.
In the original MaskGIT generation examples, roughly how many refinement iterations were often used?
The guide cites roughly 8 to 12 steps as an example from the original paper’s image-generation setups; the count is configuration-dependent rather than a universal requirement.
