Essentially optimal interactive certificates in linear algebra
Proceedings of the 39th International Symposium on Symbolic and Algebraic Computation - ISSAC '14. Presented at the the 39th International Symposium.

Sparse polynomial interpolation codes and their decoding beyond half the minimum distance
Proceedings of the 39th International Symposium on Symbolic and Algebraic Computation - ISSAC '14. Presented at the the 39th International Symposium.
Event: the 39th International Symposium
TL;DR:
A new polynomial-time list decoding algorithm uses sub-sequences of the received evaluations indexed by an arithmetic progression, allowing the decoding for a larger radius, that is, more errors in the evaluations while returning a list of candidate sparse polynomials.
