Matrix completion under interval uncertainty

•Matrix completion under interval uncertainty can be encoded using box constraints.•E.g. in collaborative filtering, a rating of 2 can be replaced by an interval 1–3.•Present-best results in terms of statistical performance are provided for a benchmark.•Convergence of randomized coordinate-descent m...
