What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
The third is whether always-on microcontroller-class inference is fundamentally a wake-up filter for a more capable downstream accelerator, or an increasingly capable endpoint in its own right. The wake-up-filter view is supported by the duty-cycle model above: for the rare-trigger workloads this category is classically used for, dominates average power regardless of how much the active-phase model can do, so there is limited incentive to make it much more capable. The endpoint view is supported directly by MCUNet’s results, which push a real classification task past 70% ImageNet top-1 accuracy on commodity microcontroller memory budgets until recently assumed adequate…
Learn the underlying idea
A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
