Towards Blackbox Identity Testing of Log-Variate Circuits
Derandomization of blackbox identity testing reduces to extremely special circuit models. After a line of work, it is known that focusing on circuits with constant-depth and constantly many variables is enough (Agrawal,Ghosh,Saxena, STOC'18) to get to general hitting-sets and circuit lower bounds. This inspires us to study circuits with few variables, eg. logarithmic in the size s.
We give the first poly(s)-time blackbox identity test for n=O(log s) variate size-s circuits that have poly(s)-dimensional partial derivative space; eg. depth-3 diagonal circuits (or Sigma wedge Sigma^n). The former model is well-studied (Nisan,Wigderson, FOCS'95) but no poly(s2^n)-time identity test was known before us. We introduce the concept of cone-closed basis isolation and prove its usefulness in studying log-variate circuits. It subsumes the previous notions of rank-concentration studied extensively in the context of ROABP models
IMPROVED METHOD FOR THE DISCRETE FAST FOURIER-TRANSFORM
A new algorithm is proposed here for the discrete fast Fourier transform with greatly reduced aliasing which is known to be inherent in the conventional algorithm of Cooley and Tukey, unless the function is band limited and the sampling frequency satisfies the Nyquist condition. Like the algorithm recently proposed by Schütte and extended by Mäkinen in this journal, this is also based on the polynomial expansion of the function to be transformed but more general in formulation and less restrictive than theirs. Its power is demonstrated with a few non-band-limited functions that can be exactly transformed with chosen limits as usually met in different experimental situations. In all cases tried, this yields, in general, much improved accuracy in comparison to others at little or no corresponding increase of computation time
Improvements in primary care skills and knowledge with a vocational training program: a medical student's perspective
Anita Ghosh, Diya Kapila, Trisha Ghosh Faculty of Medicine, Imperial College London, Kensington, London, UK We read with great interest, the article by Djalali et al evaluating the impact of a training program during residency, targeted toward primary care.1 This resonated with us from a medical student’s perspective as we are fortunate enough to have a similar program at medical school. Although the article states that future career choices are more likely to be determined during residency, we believe that this can be nurtured earlier through knowledge and early exposure.
