Learning never stops. When SAS had to change this year’s SAS Global Forum (SASGF) to a virtual event, everyone was disappointed. I am, however, super excited about all of the papers and stream of video releases over the last month (and I encourage you to register for the upcoming live
Welcome to the first post for the Getting Started with Python Integration to SAS Viya series! With the popularity of the Python programming language for data analysis and SAS Viya's ability to integrate with Python, I thought, why not create tutorials for users integrating the two? To begin the series
Whether you like it or not, Microsoft Excel is still a big hit in the data analysis world. From small to big customers, we still see fit for daily routines such as filtering, generating plots, calculating items on ad-hoc analysis or even running statistical models. Whenever I talk to customers,
Let’s be honest, there is a lot of SAS content available on the web. Sometimes it gets difficult to navigate through everything to find what you need, especially if you are looking for complimentary resources. Training budgets can be limited or already used for the year, but you’re still interested
As a long-time SAS 9 programmer, I typically accomplish my data preparation tasks through some combination of the DATA Step, Proc SQL, Proc Transpose and some housekeeping procs like Proc Contents and Proc Datasets. With the introduction of SAS Viya, SAS released a new scripting language called CASL – a
This post describes a fully automated validation pipeline for analytical models as part of an analytical platform, which has been set up recently as part of a customer project.
Let us now take a look at a well-known metaphor for test case development in the software industry. We are referring to the idea of the “test pyramid."
In total, there are four posts in this blog series, this is the first post describing some basic principles of the DevOps (or ModelOps) approach.
Bringing the power of SAS to your Python scripts can be a game changer. An easy way to do that is by using SASPy, a Python interface to SAS allowing Python developers to use SAS® procedures within Python. However, not all SAS procedures are included in the SASPy library. So,
Site relaunches with improved content, organization and navigation. In 2016, a cross-divisional SAS team created developer.sas.com. Their mission: Build a bridge between SAS (and our software) and open source developers. The initial effort made available basic information about SAS® Viya® and integration with open source technologies. In June 2018, the
While growing up in the 80's, I watched The Golden Girls on TV with my Grandma Betty. Now, when my sister visits, we binge watch reruns on TV Land. I was excited when I saw for this Halloween, you could buy Golden Girls costumes! Too bad they sold out right
This article continues a series that began with Machine learning with SASPy: Exploring and preparing your data (part 1). Part 1 showed you how to explore data using SASPy with Python. Here, in part 2, you will learn how to begin to prepare your data to use it within a
Editor's Note: This article was translated and edited by SAS USA and was originally written by Makoto Unemi. The original text is here. SAS previously provided SAS Scripting Wrapper for Analytics Transfer (SWAT), a package for using SAS Viya functions from various general-purpose programming languages such as Python. In addition
If you use Microsoft Teams for collaboration, you should use it for operational messages too. You can use SAS to automate tailored notices to your Teams Channel.
A simple example of how you can combine SAS and open-source technologies to solve real business issues.
In a previous post, Zero to SAS in 60 Seconds- SAS Machine Learning on SAS Cloud, I documented my experience with a SAS free trial on the SAS Cloud. Well, the engineers at SAS have been busy and created another free trial. The new trial covers SAS Event Stream Processing
How we built a recommendation engine for new topics on communities.sas.com. We used data, machine learning, and DevOps to build a scoring engine with SAS.
In his article How to use CASL to develop and work with user-defined CAS actions, Brian Kinnebrew defines CASL as "a language specification used by the SAS client to interact with and provide easy access to Cloud Analytic Services (CAS). CASL is a statement-based scripting language with many uses and
As a data scientist, did you ever come to the point where you felt the need for an evolved analytics platform bringing together the disparate skills of open source and commercial software? A system that can enable advanced analytic capabilities. This is now possible and easy to implement. With many
This article is a follow-on to a recent post from Jeff Owens, Getting started with SAS Containers. In that post, Jeff discussed building and running a single container for a SAS Viya runtime/IDE. Today we will go through how to build and run the full SAS Viya stack - visual
Two sayings I’ve heard countless times throughout my life are “Work smarter, not harder,” and “Use the best tool for the job.” If you need to drive a nail, you pick up a hammer, not a wrench or a screwdriver. In the programming world, this could mean using an existing
In the article Serverless functions and SAS Viya - a good match I discussed using serverless functions to deliver SAS Viya applications. Ignoring all the buzz words, a serverless function boils down to a set of REST APIs. So, if you tried the example you are now a REST API
As word spreads that SAS integrates with open source technologies, people are beginning to explore how to connect, interact with, and use SAS in new ways. More and more users are examining the possibilities and with this comes questions like: How do I code A, integrate B, and accomplish C?
You are a data scientist, in your office, doing data scientist-y things when, your manager's, manager's, manager makes an impossible request. She wants you take a raw data set from the stem cell research team, scrub the data, create and score models, and be ready to rescore when new data
Whether you are a strong believer in the power of dividing by zero, agnostic, undecided, a supporter, denier or anything in between and beyond, this blog post will bring all to a common denominator. History of injustice For how many years have you been told that you cannot divide by
SAS Viyaの分析機能をPythonから利用するためのハイレベルAPIパッケージであるDLPyでは、kerasと同等の簡潔なコーディングで、複雑な画像処理やディープラーニングを実行することができます。 そして、DLPyでは、kerasと同様に、2つの手法でディープラーニングのモデルを構築することができます。 Sequential modelとfunctional API modelです。 Sequentialとは、その名の通り、レイヤーを順序通りに積み重ねて、順序通りに実行していくモデルです。 以下は、DLPyを用いて、PythonからSAS Viyaのディープラーニング機能を使用して画像分類向けsequential modelのネットワークを定義している例です。 In [10]: model1 = Sequential(sess, model_table='Simple_CNN') model1.add(InputLayer(3, 224, 224, offsets=tr_img.channel_means)) model1.add(Conv2d(8, 7)) model1.add(Pooling(2)) model1.add(Conv2d(8, 7)) model1.add(Pooling(2)) model1.add(Dense(16)) model1.add(OutputLayer(act='softmax', n=2)) In [11]: model1.print_summary() Out[11]: In [12]: model1.plot_network() Out[12]: 一方、functional APIは、sequentialでは、表現することが難しい、より複雑な構造のモデルを構築する際に利用されます。 以下は、kerasの公式サイトに記載されている文面です。 “functional APIは,複数の出力があるモデルや有向非巡回グラフ,共有レイヤーを持ったモデルなどの複雑なモデルを定義するためのインターフェースです.” そして、DLPyでは、kerasと同様にsequential modelだけでなく、functional API modelの構築も可能になっています。 以下はその一例として、複数の入力と出力を持つような画像分類のためのディープラーニングモデルのネットワーク例です。 まず、テンソルオブジェクトを返すInput()によって、2つのテンソル、グレースケール画像とカラー(RGB)画像、を定義します。 グレースケール画像は2つの畳み込み層に送り込まれます。カラー画像はそれらとは別の畳み込み層に送り込まれます。
Also celebrating is your bank's branch manager. She was skeptical when headquarters analysts equipped branches for "Cloud-based application using SAS" , saying it would speed up loan applications. But your quick, frictionless transaction proved them right.The bank's accountants are happy too. The new pay-as-you-go mode of using SAS software in
SAS Decision Manager enables you to build and test decisions to use in batch processes, real-time web applications or with SAS Event Stream Processing. In this blog, I explain how to use Rulesets in an Event Stream Process project. If you are streaming data using SAS Event Stream Processing and
I look forward to Pi Day every year at SAS because it's a day of celebration including yummy pies and challenging games that challenge you to recall the digits after the decimal point in Pi. Plus you get to wear Pi t-shirts (I have about seven). Today, though we are going to talk about DLPy which sounds like Pi and
