In this series' fifth post, Autotune models to avoid local minimum breakdowns, Wayne discusses two autotune methods, grid search and Bayesian optimization. According to another colleague’s paper, Automated Hyperparameter Tuning for Effective Machine Learning, Bayesian optimization is currently popular for hyperparameter optimization. Recently, I read a post on Github which demonstrated the Bayesian optimization procedure through a great demo using Python, and I wondered if I could build the same with the SAS matrix language, SAS/IML. In this article, ... Read More

Why are there so many servers? What is the difference between distributed and non-distributed installations? Understanding SAS 9.4 architecture is key to tackling the tasks and responsibilities that come with SAS administration and will help you know where to look to make changes or troubleshoot problems. One of the ways I have come to think about SAS 9.4 architecture is to think of it like building a house. So, what ... Read More

Image by Flickr user ming1967 As we honor Mental Health Month, there are many calls to reduce suffering. Seems reasonable, right? It’s even in California’s Mental Health Services Act (MHSA), where public systems are called to “reduce subjective suffering.” And as we broadly focus more on outcomes in health, measuring suffering (and hopefully its reduction) is crucial. In order to measure something, we have to define it. While some definitions of suffering simply refer to the presence of symptoms, does the ... Read More

Because of these capabilities highly customized models can be developed in VTA. The rules used in this blog are basic. Developing linguistic rules and accurately categorizing documents requires subject matter expertise and understanding the grammatical structure of the language(s) used. I will use a data set that contains information on 1527 randomly selected movies: their titles, reviews, MPAA Ratings, Main Genre classifications and Viewer Ratings. Two customized categories will be developed ... Read More

It is remarkable, therefore, that with relatively simple mental arithmetic, you can obtain bounds for the eigenvalues of a matrix of any size. The bounds are provided by using a marvelous mathematical result known as Gershgorin's Disc Theorem. For certain matrices, you can use Gershgorin's theorem to quickly determine that the matrix is nonsingular or positive definite. The Gershgorin Disc Theorem appears in Golub and van Loan (p. 357, 4th Ed; p. 320, 3rd Ed), where it is called the Gershgorin Circle Theorem. The ... Read More

Open banking may not have made much of an impression on consumers yet. But it’s a topic that the industry cannot afford to ignore. Tier one UK banks are already bound to grant licensed startups access to transaction-level data, and smaller banks are likely to have to follow suit in the near future. The potential impact on the banking landscape is profound. Today, the standard business model for retail banks is to build strong ... Read More

Eso significa que todas las organizaciones que manejan datos de ciudadanos europeos (sin importar dónde estén ubicadas) deben cumplir con los más altos estándares de transparencia y privacidad para garantizar la seguridad de la información y un manejo ético de la misma. A pesar de que la regulación es europea, su impacto tiene repercusiones en todo el mundo pues la ley claramente señala que cualquier organización que trate con datos de ... Read More
