This article shows how to call the percentile action from PROC CAS to estimate percentiles of variables in a CAS data table. Percentiles and quantiles are essentially the same (the pth quantile is the 100*pth percentile for p in [0, 1]), so this article also shows how to estimate quantiles in SAS Viya. I previously mentioned that some SAS procedures are CAS-enabled, which means that they will call a CAS action that runs on the CAS server if you specify a CAS table on ... Read More

Feed: SAS Blogs. Author: SAS Jedi. I use macros extensively in my SAS programs, and over the years have accumulated a few that I find quite useful. The integration of GIT and SAS Studio has made it easy to build a re-usable macro library, so I've put some of the more polished macros I've written in a GIT repository to share. You can generate a list of the macro files available with this bit of SAS code (which leverages one of those macros) %let thisMacro=listrepofiles; filename mcode temp; proc http url="https://raw.githubusercontent.com/SASJedi/sas-macros/master/%qlowcase(&thisMacro).sas" out=mcode; run; %include mcode /source2; filename mcode; %&thismacro(?)

Feed: SAS Blogs. Author: Peter Styliadis. Welcome to the sixth installment in my series Getting Started with Python Integration to SAS Viya. In previous posts, I discussed how to connect to the CAS server, how to execute CAS actions, and how to work with the results. Now it's time to generate simple descriptive statistics of a CAS table. Let's begin by confirming the cars table is loaded into memory. With a connection to CAS established, execute the tableInfo action to view available in-memory tables. If necessary, you can execute the following code in SAS Studio to load the sashelp.cars table into memory. conn.tableinfo(caslib="casuser") The ... Read More

SAS Visual Data Mining and Machine Learning은 FQN(Fitted Q-Networks)과 함께 배치 강화 학습 기능을 한동안 제공했습니다. 흥미로운 소식은 SAS가 DQN(Deep Q-Networks)을 통해 온라인 "실시간" 강화 학습을 제공한다는 것입니다. 강화 학습이란 무엇인가? 강화 학습은 머신러닝 모델 중의 하나입니다. 머신러닝의 종류에는 지도 학습, 비지도 학습, 강화 학습 등이 있을 수 있습니다. 지도 학습과 달리 강화 학습에는 감독자(Supervisor)가 없습니다. 대신 피드백 메커니즘 역할을 하는 보상(Reward) 신호(Signal)가 있습니다. 강화 학습의 목표(Objective)는 일련의 행동에 걸쳐 축적된 장기적 보상을 ...

SAS ESP "factory" 서버가 더 이상 필요하지 않습니다 이전에는 SAS ESP 6.2 및 이전 버전에서 개발자가 ESP 프로젝트를 설계하기 위해 먼저 최소한 하나의 ESP 서버의 작동해야 하고 데이터 소스의 커넥터의 설정값, 입력과 출력 변수, ASTORE 파일을 동적으로 검색해야 했습니다. 쿠버네티스 기반 ESP 버전을 사용하면 개발자가 ESP 프로젝트 설계를 위해 그전처럼 ESP 서버를 먼저 가동하지 않아도 기본적으로 제공되는 ESP 클러스터에 연결만 하면 됩니다. 왜냐하면 특정 쿠버네티스의 ...
