ZipLoRA

“Nevertheless, the merging process often leads to interference between the parameters of different adapters~Ortiz-Jimenez_Favero_Frossard_2023. This oversight in failing to optimally align the integrated parameters can result in a notable performance degradation of the merged model, leading to ineffective preservation of the distinct qualities of both content and style~yadav2023resolving.”

“as the $$-prediction loss tends to capture broad concepts rather than the precise global structure.”

“However, such approaches, along with methods like B-LoRA, ComposLoRA, CMLoRA, remain heavily dependent on model-specific architectures rombach2022high,podell2023sdxl and domain constraints.”

“However, ZipLoRA requires an additional optimization stage for each new combination of content and style, thereby restricting the flexibility of reusing trained LoRA weights, which is LoRA's primary advantage.”

“merging the attention layers of two LoRAs at the element level could lead to a smoothing of style details and textures, or even the loss of object characteristics.”

“However, this approach requires several minutes per merge at test time, limiting its usability in real-time scenarios.”
