fine-tuning are much larger versions of the sequences or images so this may not be an optimal thing to do when you're doing local predictions local spatial predictions Bosch num is hard to use so applying mass ROM is hard but then you really want to use batch room for a downstream task so that makes CPC version too little sore in sense it's not particularly suitable for downstream tasks if you really care about state-of-the-art performance and finally the splitting process mechanism is very slow on a on a matrix multiplication
