  2. Robust principal component analysis - Wikipedia

    en.wikipedia.org/wiki/Robust_principal_component...

    The 2014 guaranteed algorithm for the robust PCA problem (with the input matrix being = +) is an alternating minimization type algorithm. [12] The computational complexity is (⁡) where the input is the superposition of a low-rank (of rank ) and a sparse matrix of dimension and is the desired accuracy of the recovered solution, i.e., ‖ ^ ‖ where is the true low-rank component and ^ is the ...

  3. Probabilistically checkable proof - Wikipedia

    en.wikipedia.org/wiki/Probabilistically...

    In computational complexity theory, a probabilistically checkable proof (PCP) is a type of proof that can be checked by a randomized algorithm using a bounded amount of randomness and reading a bounded number of bits of the proof. The algorithm is then required to accept correct proofs and reject incorrect proofs with very high probability.

  4. Debt service coverage ratio - Wikipedia

    en.wikipedia.org/wiki/Debt_service_coverage_ratio

    Debt Service = (Principal Repayment) + (Interest Payments) + (Lease Payments) [3] To calculate an entity's debt coverage ratio, you first need to determine the entity's net operating income (NOI). NOI is the difference between gross revenue and operating expenses.

    The Biden administration proposed expanding coverage of weight loss medication to Medicaid and Medicare recipients. RFK Jr. may not be such a fan.

  8. Algorithms for calculating variance - Wikipedia

    en.wikipedia.org/wiki/Algorithms_for_calculating...

    Algorithms for calculating variance play a major role in computational statistics.A key difficulty in the design of good algorithms for this problem is that formulas for the variance may involve sums of squares, which can lead to numerical instability as well as to arithmetic overflow when dealing with large values.
