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 single largest lever most teams have over is not the inference itself but how rarely it needs to run, which is why event-driven sensing — waking the system only when a sensor’s own front end detects a change worth acting on, rather than sampling and running inference on a fixed clock — routinely dominates every optimization applied to the model. That principle carries directly into the next section’s sensor discussion, because some sensor architectures build the event-driven property into the transducer itself rather than leaving it to software.
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.
