Is deep learning the latest fad?

In my 25 years at SAS, I‘ve noticed the continued use of important algorithms, such as logistic regression and decision trees, which I’m sure will continue to be steady staples for data scientists. After all, they’re easy-to-use, interpretable algorithms. However, they’re not always the most accurate and stable classifiers. To

Simulate multivariate clusters in SAS

This article shows how to simulate data from a mixture of multivariate normal distributions, which is also called a Gaussian mixture. You can use this simulation to generate clustered data. The adjacent graph shows three clusters, each simulated from a four-dimensional normal distribution. Each cluster has its own within-cluster covariance,

SAS Viyaで線形回帰

SAS Viyaで線形回帰を行う方法を紹介します。言語はPythonを使います。 SAS Viyaで線形回帰を行う方法には大きく以下の手法が用意されています。多項回帰：　simpleアクションセットで提供。一般化線形回帰または一般線形回帰：　regressionアクションセットで提供。機械学習で回帰：　各種機械学習用のアクションセットで提供。今回は単純なサインカーブを利用して、上記3種類の回帰モデルを作ってみます。【サインカーブ】 -4≦x<4の範囲でサインカーブを作ります。普通に $$y = sin(x) $$を算出しても面白みがないので、乱数を加減して以下のようなデータを作りました。これをトレーニングデータとします。青い点線が $$y=sin(x)$$ の曲線、グレーの円は $$y=sin(x)$$ に乱数を加減したプロットです。グレーのプロットの中心を青い点線が通っていることがわかります。今回はグレーのプロットをトレーニングデータとして線形回帰を行います。グレーのプロットはだいぶ散らばって見えますが、回帰モデルとしては青い点線のように中心を通った曲線が描けるはずです。トレーニングデータのデータセット名は "sinx" とします。説明変数は "x"、ターゲット変数は "y" になります。各手法で生成したモデルで回帰を行うため、-4≦x<4 の範囲で0.01刻みで"x" の値をとった "rangex" というデータセットも用意します。まずはCASセッションを生成し、それぞれのデータをCASにアップロードします。 import swat host = "localhost" port = 5570 user = "cas" password = "p@ssw0rd"

The singular value decomposition and low-rank approximations

A previous article discussed the mathematical properties of the singular value decomposition (SVD) and showed how to use the SVD subroutine in SAS/IML software. This article uses the SVD to construct a low-rank approximation to an image. Applications include image compression and denoising an image. Construct a grayscale image The

The singular value decomposition: A fundamental technique in multivariate data analysis

The singular value decomposition (SVD) could be called the "billion-dollar algorithm" since it provides the mathematical basis for many modern algorithms in data science, including text mining, recommender systems (think Netflix and Amazon), image processing, and classification problems. Although the SVD was mathematically discovered in the late 1800s, computers have

Analytics-driven forecasting means more than measuring trend and seasonality. It includes all categories of methods (e.g. exponential smoothing, dynamic regression, ARIMA, ARIMA(X), unobserved component models, and more), including artificial intelligence, but not necessarily deep learning algorithms. That said, deep learning algorithms like neural networks can also be used for demand forecasting,
