Dear organizers,
We are currently participating in the MAI 2025 Image Denoising Challenge.
While reviewing the challenge guidelines, we noticed a potential contradiction and would like to kindly ask for clarification regarding the expected format of the submitted model:
- In the challenge summary (as shown on the MAI website), the "Runtime evaluation mode" is listed as "TFLite (LiteRT) FP32 models".
- However, in the runtime validation instructions, it is stated that we should evaluate our models on-device using "AI Benchmark (FP16 mode + TFLite GPU delegate)".
Given this, could you please clarify the following:
1. Are participants required to submit **FP32 TFLite models**, or is it acceptable (or even recommended) to submit **FP16-quantized TFLite models**?
2. Will **FP16 models** be evaluated properly on the final runtime evaluation devices (Snapdragon 8 Elite Adreno / Dimensity 9400 Mali GPU)?
We would greatly appreciate your guidance so we can ensure our model is submitted in the correct format.
3. Regarding the runtime evaluation and ranking:
➤ Which GPU is used for runtime scoring in the final ranking — **Snapdragon 8 Elite (Adreno GPU)** or **Dimensity 9400 (Mali GPU)**?
➤ Or is the slowest runtime among the two used as the official score?
