Others

There were some guest talks: Vijay Chandru talked about linear constraints and logic. Subhashis Bannerjee gave a nice exposition of the difficulties in using algebro-geometric methods in computer vision (even though one is dealing with fairly small matrices and dimensions); the exposition was enlivened with pictures of 3D panoramic scenes reconstructed using some of these methods. Sundarrajan talked about coding theory, in particular Euclidean space codes and trellises. For sheer fervour and direct contact with the audience in presenting material, he was unmatched at this (and many other) workshops! It was good to hear an exposition of how coding is moving towards reaching Shannon's limit etc from an engineer (he is from the EE Dept) - none of the cynical ``Ah, so that's been done now, is it?'' and lots of the ``how wonderful, such a simple idea but it works''. At the end, he mentioned several open problems and urged us computer scientists to find the solutions. Such heartening faith in us!
