MoLA adapts forecast steps with shared low-rank experts, addressing a limitation in multi-task time-series forecasting: one linear decoder maps shared representations to every future step. It divides the horizon into segments and learns segment-specific mixtures of shared adaptations. On Weather at horizon 96, MSE is 0.173 versus 0.201 for the iTransformer MT-F baseline, a result limited to one dataset and horizon.
