Recovery of spectrum from estimated covariance matrices and statistical kernels for machine learning and big data
Saba Amsalu, Juntao Duan, Heinrich Matzinger +1
In this paper we propose two schemes for the recovery of the spectrum of a covariance matrix from the empirical covariance matrix, in the case where the dimension of the matrix is…
A Monte Carlo Approach to the Fluctuation Problem in Optimal Alignments of Random Strings
Saba Amsalu, Raphael Hauser, Heinrich Matzinger
The problem of determining the correct order of fluctuation of the optimal alignment score of two random strings of length has been open for several decades. It is known that t…
Sparse long blocks and the variance of the longest common subsequences in random words
S. Amsalu, C. Houdré, H. Matzinger
Consider two independent random strings having same length and taking values uniformly in a common finite alphabet. We study the order of the variance of the length of the longest…
Sparse Long Blocks and the Micro-Structure of the Longest Common Subsequences
S. Amsalu, C. Houdré, H. Matzinger
Consider two random strings having the same length and generated by an iid sequence taking its values uniformly in a fixed finite alphabet. Artificially place a long constant block…
