About mixtrain in DynaBOA code

[dqj5182]

Good morning,

Just have a question regarding mixtrain argument in DynaBOA code (including lower_level_mixtrain and upper_level_mixtrain). I have confused with what exactly is mixtrain. According to the code, it seems that it allows the model to do label loss on h3.6m batch extracted from retrieval. However, the paper does not seem to mention mixtrain but mention an ablation study on "Adapting to non-stationary streaming data with highly mixed 3DPW and 3DHP videos.". But here, I am not sure whether the mixtrain procedure really uses 3DHP videos in the code. Could you make this clear on how to understand the mixtrain in the DynaBOA code in relation with the T-PAMI paper?
