Have you ever tried to type a movie title by using a TV remote control? Both Netflix and Amazon Video provide an interface (a virtual keyboard) that enables you to use the four arrow keys of a standard remote control to type letters. The letters are arranged in a regular
The data I was analyzing was about “trust.” Maybe that’s what got me thinking about Stephen Sondheim, the Broadway composer and lyricist of musicals like Sunday in the Park with George and Into the Woods and the lyricist for West Side Story. Trust is a heavy emotional topic. Developmental psychologists
지난 7월 정부는 스마트 그리드(smart grid) 서비스가 구현되는 체험 단지 조성 등을 골자로 하는 ‘제 2차 지능형 전력망 기본 계획’을 발표했습니다. 이에 따라 올해부터 2022년까지 스마트 그리드 서비스 활성화, 각종 인프라 구축 등에 4조5,000억 원을 투자할 방침입니다. 스마트 그리드는 전기의 생산, 운반, 소비 과정에 정보통신기술(ICT)을 접목해 효율성을 높일 수 있도록
Here in North Carolina (NC), we're pretty much resigned to the fact that many of the hurricanes in the Atlantic Ocean are going to visit us. NC sticks out farther into the ocean than most of our neighboring states, and that just makes a tempting target for the hurricanes. But
Versicherer gehören zu den Spätstartern in Sachen Digitalisierung – selbst im Kundenservice, wo sich die digitale Vernetzung förmlich aufdrängt. Oft spielt dabei die Unternehmensgröße und die damit verbundenen festgefahrenen Strukturen, Legacy Systeme und Prozesse eine große Rolle. Sie macht es auch schwer, auf neue Trends spontan zu reagieren. Und dann
Ich bin bereits zum dritten Mal in San Francisco und wieder mal sehr beeindruckt von der großartigen Architektur der Golden Gate Bridge. Diesmal lasse ich mich mit dem Boot nach Sausalito, auf die andere Seite der Bucht, übersetzen. Das dortige Orts-Museum erzählt dem Besucher von der bewegten Geschichte des Ortes
This blog post introduces the use of deep learning to train a deep neural network to further improve performance; and hybrid architectures.
Given a rectangular grid with unit spacing, what is the expected distance between two random vertices, where distance is measured in the L1 metric? (Here "random" means "uniformly at random.") I recently needed this answer for some small grids, such as the one to the right, which is a 7 x 6
El pasado 17 de junio Colombia eligió a Iván Duque, el candidato del Centro Democrático, como su próximo presidente. El ganador junto con su gabinete, que ejercerán desde el próximo 7 de agosto y hasta el 2022, recibirán un país que aunque se recupera económicamente, aún enfrenta grandes retos en
Ich blinzele, kann kaum was sehen. Die Sonne scheint mir direkt ins Gesicht. Hell, schmerzhaft, stechend – aber ich weiß, dass alle meine Sinne geschärft sein müssen. Ich bemühe mich zu sehen, was vor mir liegt. Denn ich fahre 60 km/h und fühle mich dabei fast blind. Und um mich
I usually create very technical graphs, that just focus on conveying the information in a concise and straightforward manner (no wasted colors, and nothing to distract you from the data). But sometimes, depending on your audience and the purpose of the graph, you might need to create a graph that
PC Magazine defines the broad industry term Software as a Service (SaaS) as, “Software that is rented rather than purchased. Instead of buying applications and paying for periodic upgrades, SaaS is subscription based, and upgrades are automatic during the subscription period.” SaaS, according to the same source, is ideally suited
Before grabbing that streaming data so quickly, Joyce Norris-Montanari says you should ask a few questions.

Continued fractions show up in surprising places. They are used in the numerical approximations of certain functions, including the evaluation of the normal cumulative distribution function (normal CDF) for large values of x (El-bolkiny, 1995, p. 75-77) and in approximating the Lambert W function, which has applications in the modeling
Many of the most beautiful areas in the US are owned by the government, to preserve them and allow access for everyone to enjoy them. And most US schools are traditionally closed during the summer, which provides families a great opportunity to go visit state and federal lands (parks, forests,
Are you curious? Do you have a passion for science, technology, engineering and math (STEM)? Do you enjoy robotics or statistics? Do you like to solve hard problems? If you answered yes to any of the above, you might have what it takes to be a data scientist. Recently, I
암 치료는 매우 힘든 과정입니다. 따라서 환자별 최적의 치료법을 선택하고, 환자가 효과 없는 치료법으로 인해 필요 이상의 고통을 받지 않도록 하는 것이 중요한데요. 검사를 통해 치료의 진척 상황을 측정할 수는 있지만, 많은 환자들이 치료 과정을 변경하기에는 너무 늦은 시기까지 처방의 효과를 알지 못합니다. 그렇다면 만약 특정 암 치료의 효과를 수일
Hybrid computers that marry CPUs and devices like GPUs and FPGAs are the fastest computers, but they are hard to program. This post explains how deep learning (DL) greatly simplifies programming hybrid computers.
Hace algún tiempo, asistí a una presentación en la que un ejecutivo de un fabricante de teléfonos argumentaba que el teléfono perfecto debería incluir un botón para cada funcionalidad importante: para ajustar el volumen, para tomar fotos, para hacer llamadas. En ese mismo evento, un representante de Apple aseguraba que
In the SAS/IML language, you can only concatenate vectors that have conforming dimensions. For example, to horizontally concatenate two vectors X and Y, the symbols X and Y must have the same number of rows. If not, the statement Z = X || Y will produce an error: ERROR: Matrices
机上で男女が世界地図を広げて、何かの打ち合わせをしています。 航空会社A社の企画担当が、競合他社の路線を分析しているのか？ それとも、これから二人で行く海外旅行のプランを立てているのか？ いえいえ、これはSAS Visual Analyticsで作成されたダッシュボードの画面です。 このダッシュボードの構成は以下の通りです。 ・使用しているデータ：OpenFlightsで公開されている世界の空港の利用状況のデータ ・真ん中の世界地図：「ネットワークダイアグラム」オブジェクトを使用し、背景に地図を表示して、路線を描画 バブルの大きさは、利用頻度を表しています。 ・左側の棒グラフ：利用頻度の高いトップ１０の航空会社 ・右下と左下の数値：「キーの値」オブジェクトを使用し、注目すべき指標をクローズアップしています。例えば右下の値は、利用頻度が最も高い空港名とその数を示しています。 ・人の手や机、カメラ、パソコン等は背景に使用している画像です。 今、このダッシュボードでは、左側の棒グラフ上で「Air China」が選択され、ネットワークダイアグラムと２つの指標はAir Chinaに自動的に絞り込まれた内容が表示されています。 でも、まだ、これは張りぼて？ と思っていませんか。 以下は、左側の棒グラフ上で「US Airways」を選択した状態です。 ネットワークダイアグラムや２つの指標の内容が変わっているのがわかりますね。 ご覧の通り、インタラクティブなダッシュボードです。 みなさんも、こんなクールなダッシュボードで戦略を練ってみれば、新たなアイデアが湧いてくるかもしれませんね。 このブログは、SAS CommunityサイトのVisual Analytics ギャラリーに公開されている内容に基づいています。
If you're good at games like Wheel of Fortune, Scrabble, or Words with Friends, you've probably figured out that certain letters appear more often than others. But do you have a cool way to figure out which letters appear most & least frequently? How about using a computer to plot
인공지능(AI), 사물인터넷(IoT) 등 다양한 디지털 기술이 융합되면서 기업의 마케팅 전략도 혁신을 거듭하고 있습니다. 특히 고객이 특정 순간과 장소에서 기대하는 바를 충족시키는 ‘개인화된 경험’이 핵심 마케팅 역량으로 떠올랐는데요. 이를 위해서는 고객 데이터를 실시간으로 분석해 개별 고객의 특성과 원하는 바를 보다 잘 이해하고, 언제 어디서나 고객의 소비 여정과 함께하는 실시간 마케팅(Real-time marketing) 전략을 구현해야
Note: The following concludes an eight-part serialization of selected content from Steve Morlidge's The Little (Illustrated) Book of Operational Forecasting. Good forecasts don’t always ‘look right’ Many forecasters believe that they can tell how good a forecast is by ‘eyeballing’ it. Good forecasts just ‘look right’ or so they would
The true test of when a technology has become mainstream is when it is being widely used across the whole business, from customer-facing functions to backroom work. Analytics has been customer-focused for some time, and has also been widely used for individual performance, for example, by sports teams. The advent
A SAS programmer recently asked me how to compute a kernel regression in SAS. He had read my blog posts "What is loess regression" and "Loess regression in SAS/IML" and was trying to implement a kernel regression in SAS/IML as part of a larger analysis. This article explains how to
Note: Following is an eight-part serialization of selected content from Steve Morlidge's The Little (Illustrated) Book of Operational Forecasting. The measurement challenge So here is the forecasters dilemma: There will always have forecast error. The challenge is to work out the cause of the error and to take the appropriate
Using relative file paths in your SAS programs? Use the new DLGCDIR function to manage your SAS working directory -- even in SAS Enterprise Guide or SAS Studio -- to ensure your programs are working the way they ought to.
We'll take a short break from the Steve Morlidge book serialization, to announce that SAS Research & Development has again provided $10,000 in funding for the SAS/IIF grant program. Both academics and industry practitioners are encouraged to apply and conduct original research for improving the practice of forecasting. SAS/IIF Grants
