A Time of Giving
Fall…it’s my favorite time of year. The air is crisp, the leaves are colorful and exercising outdoors is once again appealing. Most of all, its this time of year that I turn my attention to one of my favorite events of the year: #GivingTuesday. While Cyber Monday and Black
Visualize the feasible region for a constrained optimization
When solving optimization problems, it is harder to specify a constrained optimization than an unconstrained one. A constrained optimization requires that you specify multiple constraints. One little typo or a missing minus sign can result in an infeasible problem or a solution that is unrelated to the true problem. This
Creating a custom 'I Voted' sticker
With today being an election day here in the US, I see a lot of people wearing the 'I Voted' sticker. This got me wondering if I could create my own sticker ... using SAS software and simple graphics primitives. :-) So I started by using Proc Gslide to create
Reporting on accelerometer data with SAS Visual Analytics

인공지능(AI)이 재정의하는 윤리는? 윤리적인 인공지능 시스템 관리를 위한 4가지 핵심요소
인공지능(AI)은 1950년대부터 머신러닝, 링크 걸기 시작 딥러닝(deep learning), 인지 컴퓨팅(cognitive computing)이 점차 발전하면서 우리와 꽤 오랜 시간을 함께 해왔습니다. 최근 달라진 점이 있다면 아마 활용할 수 있는 데이터의 양이 어마어마하게 늘었다는 것인데요. 방대한 양의 데이터 덕분에 오늘날 과거에는 불가능했던 방식으로 인공지능 기반의 모델을 학습시킬 수 있게 되었습니다. 이러한 인공지능은 지금의 세상과 거대한 데이터를 이해하는
Maps, models, and analytic problem framing
What’s the most important component of analytic analysis? The data? The model? The deployment? Getting the business problem right? All the above? Or does it simply depend on who you ask? While the model gets all the attention, and the data requires most of the effort, there is that step
Fit the Pareto distribution in SAS
Will the real Pareto distribution please stand up? SAS supports three different distributions that are named "Pareto." The Wikipedia page for the Pareto distribution lists five different "Pareto" distributions, including the three that SAS supports. This article shows how to fit the two-parameter Pareto distribution in SAS and discusses the
Visualizing cities as constellations in the night sky
Who says technical people can't have fun!?! Similar to Throwback Thursday / #TBT (when people post one of their old/nostalgic photos on social media), I like the tradition of Fun Friday when I use a fun data topic to test our software - a test can be just as rigorous using
The myths and realities of AI in health care
Health care is facing an unprecedented need to reform, drive quality and cut costs. Growth in targeted, specific treatments and diagnostic technology, coupled with a rise in people with long-term and multiple chronic conditions, is creating unsustainable demand on the system. To thrive – or even merely survive – health
Mein Vater hat den spannendsten Job der Welt, denn er ist ein Data Scientist!

SAS Viya：Python API向けパッケージ：DLPyの最新版1.0拡張機能概要紹介
SASでは、従来からオープン・AIプラットフォームであるSAS Viyaの機能をPythonから効率的に活用いただくためのハイレベルなPython向けAPIパッケージであるDLPyを提供してきました。 従来のDLPyは、Viya3.3以降のディープラーニング（CNN）と画像処理（image action set）のために作成された、Python API向けハイレベルパッケージです。 DLPyではKerasに似たAPIを提供し、より簡潔なコーディングで高度な画像処理やCNNモデリングが可能でした。 そして、この度、このDLPyが大幅に機能拡張されました。 最新版DLPy1.0では、以下の機能が拡張されています。 ■ 従来からの画像データに加え、テキスト、オーディオ、そして時系列データを解析可能 ■ 新たなAPIの提供: ・ RNN に基づくタスク: テキスト分類、テキスト生成、そして 系列ラベリング（sequence labeling） ・ 一般物体検出（Object Detection） ・ 時系列処理とモデリング ・ オーディオファイルの処理と音声認識モデル生成 ■ 事前定義ネットワーク（DenseNet, DarkNet, Inception, and Yolo）の追加 ■ データビジュアライゼーションとメタデータハンドリングの拡張 今回はこれらの拡張機能の中から「一般物体検出（Object Detection）」機能を覗いてみましょう。 SAS Viyaでは従来から画像分類（資料画像1.の左から２番目：Classification）は可能でした。例えば、画像に映っている物体が「猫」なのか「犬」なのかを認識・分類するものです。 これに加えて、DLPy1.0では、一般物体検出（資料画像1.の左から３番目：Object Detection）が可能になりました。 資料画像１.

We have updated our software for improved interpretability since this post was written. For the latest on this topic, read our new series on model-agnostic interpretability. While some machine learning models – like decision trees – are transparent, the majority of models used today – like deep neural networks, random forests, gradient boosting
Unasked fraud questions answered by AI
Artificial intelligence often seems misunderstood, especially in fraud. The same is true of machine learning. One of the amazing things about them is they ask the unasked questions. This occurs as artificial intelligence (AI) and machine learning (ML) go about their daily work. So, what is the unasked question? Too

새 금융규제로 떠오른 ‘FRTB’, 효율적인 시장 리스크 관리 전략과 구축 방안은?
FRTB(Fundamental review of the trading book)는 은행의 시장 리스크 관리 방식을 바꿀 것입니다. 바젤은행감독위원회(BCBS)가 FRTB를 발표하고 이 기준에 따라 전세계적으로 시장 리스크를 측정해 공시하도록 한 것인데요. 대다수 은행은 2020년 12월 데드라인과 바뀌고 있는 요구 사항을 보며 ‘기다려야 한다’는 결론을 내리고 있지만, 그저 기다리기만 하는 것은 위험한 전략이 될 수 있습니다. 금융
Absence makes the heart (or whole body) grow stronger
I’m on day 8 of my 10 day sabbatical from running. By day 3, I already felt anxious about not lacing up my shoes and heading out to feel the wind in my face, never mind the fact that I was still exhausted and sore from the previous week’s races.
Screaming analytics. Let your safety data whisper.
