The passage around this formula
…model with demonstrating the basic capability [ 5 ] . Joint training from scratch buys deeper cross-modal integration; it does not, on this evidence, buy strong abstract reasoning over visual patterns for free. All of here is shared and randomly initialised at t=0 , and no term is held fixed while another is optimised. That is the formal content of “native”: contrast it with the modular recipe, where the vision and language terms are each minimised separately, over separate data, to convergence, long…
