Artificial intelligence evokes high hopes. It can streamline processes, improve quality and eliminate the potential for human error. Along with the hopes come the fears, however. Is AI a threat to humanity? Whom will it replace, if anyone? How can we deploy it ethically? We spoke to the SAS Head

SAS Studio Taskの紹介 仕事の中で、このような状況に遭遇したことはないでしょうか？普段Enterprise Guide或いはSAS Studioを利用している分析チームの中には、コーディングユーザとSAS言語ができないGUIユーザがいます。ある分析プロジェクトにおいて、特定のモデルを活用する場合に、そのモデルはSASコードを書くことで利用することはできますが、EGのGUI操作やSAS Studio のTaskだけでは活用することができません。この場合に、GUIユーザがコーディングユーザと同じような分析を行うためには、コーディングユーザが作ったSASコードを利用し、入出力情報やパラメータなどを修正した上で使用することになります。しかし、このようなやり方では、たとえば、修正を間違えることによって、エラーを起こし、コードを書いた人に助けてもらわないといけないことも時々発生していました。 この状況に置いて、SAS言語ができないユーザでも、コードを書かずにGUI上の簡単なマウス操作で実施できるような便利な機能をご紹介します。 SAS Studioには、SAS Studioカスタムタスクという機能が組み込まれています。必要な機能が既存のタスクとして用意されていなくても、プロシジャーがあれば自らタスクを簡単に作成できるインターフェースです。XML形式で必要な入出力箇所やオプションを定義することによって、GUI画面を持つタスクが簡単に作れます。そのタスクをSAS Studio上では勿論、SAS Enterprise Guide上でも使うことができます。非常に便利な機能です。この便利なSAS Studioカスタムタスクには以下のような特徴があります。 ・タスクを作る際にはSAS以外のプログラミング知識は必要ありません。 ・SAS Studioで作る場合は、XMLを書きながら、作成途中のGUIの画面を常に確認できます。 ・タスクを使う人は簡単なマウス操作で利用可能です ・そして、SAS StudioとEnterprise Guide両方での利用が可能です。 ・XMLベースなのでタスクの修正は簡単です。 ・テキストボックス、チェックボックスなど多様なコントロールを定義可能です。 SAS Studio Taskの作り方 今回は混合正規モデルを例にSAS Studio Taskの作成方法を紹介します。SAS Studio Taskを作るには二つの方法があります。 一つ目は新規で一からタスクを作成する方法です。 二つ目は既存のタスクをテンプレートとして使い、内容を修正しながらタスクを作る方法です。 今回の記事は一つ目の方法をメインとして紹介しますが、記事の最後に二つ目の方法に関しても簡単に紹介します。作成ツール（XMLエディタ）としては、SAS Studioや任意のエディターのいずれかを使用しても構いませんが、この記事では最新のSAS Studio 5.2を使用しています。操作方法などは使っているSAS Studioのバージョンによって変わる場合はありますが、定義の書き方に相違はありません。 SAS Studioを開いて、メニューから新規作成をクリックし、タスクと選択します。そして下の図のようなタスクテンプレートの画面が表示され、この画面内でSAS Studio Taskの定義を行います。まずSAS Studio Taskの定義の構造を紹介します。 最初の2行はシステムにより生成されたタスクのエンコーディングとスキーマバージョンの定義です。この部分を修正する必要はありません。 <?xml version="1.0" encoding="UTF-16"?> <Task schemaVersion="7.2">
This resource is designed primarily for beginner to intermediate data scientists or analysts who are interested in identifying and applying machine learning algorithms to address the problems of their interest. A typical question asked by a beginner, when facing a wide variety of machine learning algorithms, is “which algorithm should
When news about a new Coronavirus outbreak in China first hit the news, Falko and his colleague Anand Chitale wanted to know more. “We knew we could use SAS to analyze the data and discover new insights,” he said. By now, you’ve heard about our work helping customers combat the coronavirus pandemic.
All analytics projects have data as their foundation and this data is usually spread across a variety of databases, storage systems and locations. This diverse and complex landscape causes data scientists to spend an inordinate amount of time searching for the right data and preparing this information for analytics. It’s
A note from Udo Sglavo: A wealth of connectivity is pervasive in the data we gather across many industries. In other words, networks are all around us. A data science trend you cannot ignore is to organize, learn from, and drive decision-making based on connected data. Network analytics engines provide efficient
Most New Yorkers like to fantasize about owning and living in a classic New York City brownstone, complete with high ceilings, large windows and a front stoop. You can picture yourself sitting there alongside the iron railing with a cup of coffee while you watch the city wake up and
“It doesn’t stop being magic just because you know how it works.” Terry Pratchett, The Discworld Series Welcome to the third, and final, installment of Data Science in the Wild. In Part 1 we were lost in the woods thinking about how to start a data science project. In Part
As you begin managing your SAS code and projects in Git, here are a few guidelines for how to organize your work and collaborate with others.
If you're a SAS Enterprise Guide user who is looking to move to SAS Studio, there is a lot to like about your new coding environment.
A year ago we could not imagine stadiums being empty during the most exciting sports events, but it is a common sight now. The entertainment sector is one of the hardest hit sectors because of the COVID-19 pandemic [1]. Social distancing requirements made it impossible to have viewers in stadiums
An analyst report offers an unbiased, side-by-side, third-party evaluation of the technology in the market. These analysts know how to put the vendors through the paces and require proof of any claims that are made.
The first principle of analytics is about bringing the right analytics technology to the right place at the right time. Whether your data are on-premises, in the cloud, or at the edges of the network – analytics needs to be there with it. Being true to this principle means we
“Technology is an industry that eats its young, it is rare to come across providers that have been around for more than a human generation.” Tony Bear, Big on Data With more than 40 years in the market, SAS is one of the rare technology providers that has been around
Being overwhelmed by the volume of news isn’t a new phenomenon. But today, our sense of being overwhelmed has increased and triggered feelings of fear, frustration and anxiety, given the ongoing developments and research tied to COVID-19. How do we sift through the volume of information facing us and truly understand whether the news we consume is factual or based on
The model management process, which is part of ModelOps, consists of registration, deployment, monitoring and retraining. This post is part of a series examining the model management process, orchestrated through the Model Manager (MM) APIs.

A note from Udo Sglavo: The need for randomization in experimental design was introduced by the statistician R. A. Fisher in 1925, in his book Statistical Methods for Research Workers. You would assume that developing a successful treatment for COVID-19, the illness caused by the SARS-CoV-2 virus, will eventually conclude in
