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 oldest of the four strategies starts from an asset that is already paid for: a large model has already been trained, at whatever cost that took, and the cost is sunk. Compression treats the sunk cost as something to copy rather than repeat. Hinton, Vinyals, and Dean set out the core argument in 2015, motivated by a practical deployment problem with large ensembles: “making predictions using a whole ensemble of models is cumbersome and may be too computationally expensive to allow deployment to a large number of users” [ 1 ] . Their proposed fix — train a small “student” network to match a large “teacher” network’s full output distribution, not merely its top label — is usually written…
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.
