In this note, we obtain some improvements of results established on δ-semicontinuous functions in [3] and show that a function f : (X, τ ) → (Y, σ) is almost δ-semicontinuous if and only if f : (X, τs) → (Y, σs) is semi-continuous, where τs and σs are the semiregularizations of τ and σ, respectively.
