Implicit Regularization in Matrix Factorization

Information Theory and Applications Workshop, 2017
We study implicit regularization when optimizing an underdetermined quadratic objective over a matrix $X$ with gradient descent on a factorization of X.

On the Stability of Factorization Factors

1987
The present chapter is devoted to the study of the behaviour of the factorization factors under small perturbations of the matrix function G. Here we encounter another qualitative difference between the matrix case (n > 1) and the scalar one (n = 1). It appears that the partial indices of a matrix function and the factorization factors G± are unstable,

Factors Timing Factors

The Journal of Portfolio Management, 2017
It is common practice to refer to a factor premium’s current valuation when assessing its attractiveness—in effect using a single-value-factor model to gauge whether the factor is rich, fairly valued, or cheap. Meanwhile, studies have investigated how some factor premia are exposed to other factor premia in order to characterize their behavior over ...

Antihemophilic Factor (Factor VIII)

Annals of Internal Medicine, 1978
Antihemophilic factor (Factor VIII) is an agent in normal plasma that corrects the coagulative defect of classic hemophillia. The plasma of hemophiliacs contains normal amounts of a variant of antihemophilic factor deficient in clot-promoting properties. In contrast, von Willebrand's disease is usually associated with a true deficiency of this protein.

The Factors in Factoring Behavior

Psychometrika, 1951
Twenty years have now elapsed since Professor Thurstone’s ingenuity pulled the factor problem out of its tetrad difference quagmire. Most of us have watched Thurstone’s brain-child grow. One might say that the fledgling was so precocious as to reach maturity during the first ten years of its life.

THE STANDARDS FACTOR

ACM SIGCHI Bulletin, 1986
The Status of the HFS HCI Standards Committee is reported on in a separate article by Paul Reed of AT&T Bell Laboratories, the vice-chair of that committee. It describes the background, status and approach being followed by that committee in its attempt to develop meaningful standards for user interfaces and the development of user interfaces ...

Factor Prices, Factor Proportions, and Regional Factor Endowments

Journal of Political Economy, 1970
in two-digit manufacturing industries. These tests were based on the theoretical proposition that the South, being relatively labor-abundant by comparison with the non-South, should possess a comparative advantage in producing relatively labor-intensive commodities.
