The integral representation theorems for positive and negative definite functions obtained so far were all proved under the assumption that the semigroup contained a neutral element, i.e. a "zero" with respect to the additively written semigroup operation. We also saw that some boundedness ...
Pham proposed an information theoretic criterion [48], which requires each matrix C(k) to be positive definite. Tichavský and Yeredor gave a special weighted least square criterion [49]. Methods Problem reformulation Existing semi-nonnegative INDSCAL algorithms are based on the minimization of ...

Determining rigid body motion from accelerometer data through the square-root of a negative semi-definite tensor, with applications in mild traumatic brain injuryMild Traumatic Brain Injuries (mTBI) are caused by violent head motions or impacts. Most mTBI prevention strategies explicitly or implicitly ...
Moreover, using the similar idea, we can show that the minimal H-eigenvalue of a symmetric space tensor must be the optimal value of a semi-definite program. Computational results and discussions are provided to illustrate the significance of the results and the effectiveness of the proposed ...
We consider a structured estimation problem where an observed matrix is assumed to be generated as an |$s$| -sparse linear combination of |$N$| given |$nimes n$| positive-semi-definite matrices. Recovering the unknown |$N$| -dimensional and |$s$| -sparse weights fro...
