1. Duration

Monday, January 2nd, 2023 - January 7th, 2023

2. Learning Records

2.1 Redid the Experiments

Okay, I found the reason why the model ran like shit. The shuffle of the validation dataset made terrible results. And different batch_size or normalizations resulted in different outcomes.

2.2 Refactoring

The error said I encountered the 2 G limit of the tensorflow dataset buffer size. I tried to use the from_generator function. Unfortunately, it worked worse. I can't even finish the micro-expression training.

Furthermore, the learning rate seemed to have a huge impact on the outcomes. So whether the model is shit or the learning rate doesn't fit. I had no idea.

3. Feelings

3.1 Relieved

Finally, I finished the NTCE test on Saturday, January 7th, 2023. Then I could focus more on the experiment.
