What counterarguments exist against the scalability claims made by LNDiff?

While LNDiff presents itself as scalable due to its compressed latent space approach,
counterarguments may arise regarding certain aspects:

Complexity vs Simplicity: Some critics might argue that while compressing into a structured latent space improves efficiency,it adds complexity during model training,making it harder to interpret results accurately without thorough understanding.

Resource Intensive Training: The initial setup required for training an autoencoder followed by diffusion learning might demand substantial computational resources upfront before reaping benefits,suggesting a trade-off between scalability gains versus resource investment at onset.

Generalization Challenges: Critics may point out that while LNDiff shows promise across various datasets,the true test liesin its adaptabilityto new unseen data domains.A lackof robustness incross-domain scenarioscould hinderits scalabilityclaimsacrossa wider rangeofapplicationsanddatasets.
