OnlineStats does this: [Weights · OnlineStats Docs](https://joshday.github.io/OnlineStats.jl/stable/weights/#OnlineStatsBase.ExponentialWeight)

e.g.

```julia
julia> using OnlineStats

julia> x = randn(100);

julia> o = Mean(weight=ExponentialWeight(.1))
Mean: n=0 | value=0.0

julia> exp_smooth = [value(fit!(o, xi)) for xi in x]

```
