Linear programming (LP) and mixed integer linear programming (MILP) solvers are powerful tools. Many real-world business problems, including facility location, production planning, job scheduling, and vehicle routing, naturally lead to linear optimization models. Sometimes a model that is not quite linear can be transformed to an equivalent linear model to reduce
A Deep-Q Network (DQN) is a reinforcement learning technique that attempts to model the actions that perform best in each state in real-time.
As I sit and write this blog, the rain is coming down. The rain absorbs into the plants and Earth and supplies its liquid goodness to the aquifers in the ground promoting life above. Earth is a water planet and our bodies are 70% water. We started our beginnings in
Here is an interesting math question: How many reduced fractions in the interval (0, 1) have a denominator less than 100? The question is difficult is because of the word "reduced." If we only care about the total number of fractions in (0,1) whose denominator is less than 100, we
SAS' Leonid Batkhan reveals coding techniques that give you control of when and whether global statements are executed.
This is another in my series of blog posts where I take a deep dive into converting customized R graphs into SAS graphs. Today we'll be working on bar charts ... And to give you a hint about what data I'll be using this time, here's a picture from a SAS
Learn why a data catalog is so valuable in helping you find and use big data at your business.
A SAS customer wanted to compute the cumulative distribution function (CDF) of the generalized gamma distribution. For any continuous distribution, the CDF is the integral of the probability density function (PDF), which usually has an explicit formula. Accordingly, he wanted to compute the CDF by using the QUAD function in
Please join us on Tuesday, March 16 for what should be an exciting discussion on the current challenges and emerging best practices in demand forecasting. I'll be moderating this very distinguished panel: Nicolas Vandeput - supply chain data scientist, specialized in demand forecasting and inventory optimization; author of the book
As an American child growing up on a military base in Germany, I learned many important life lessons. One of the most important was about language and communication. I realized at age 12 that, even though I could speak German, I thought in English -- and it led me to
Date and time values are handled differently when programming in DS2. It can process databases and has access to ANSI data types, which have greater precision.
We learned this week of the passing of one of the giants in our field, Tom Wallace. Tom was as gracious and fine a gentleman as you'll meet. Through his writing, teaching, and consulting work -- in frequent collaboration with Bob Stahl -- tens of thousands of industry practitioners have
Utilities all over the country are facing multiple disruptions, from climate change to distributed energy generation to a growing need to embrace digital transformation. These challenges are more pronounced for midsize public power utilities, which are community-owned, not-for-profit and often more vulnerable to economic challenges than investor-owned utilities. As new
Reinforcement learning can help banks optimise their collections strategies to cope with an explosion in COVID-19-related delinquencies.
March is National Nutrition Month®, an annual campaign created by the Academy of Nutrition and Dietetics (the organization behind our RDN credentials). This year's theme, Personalize Your Plate, promotes creating nutritious meals to meet individuals' cultural and personal food preferences.
Chemical companies are sitting on data gold mines waiting to be exploited. Yet most of them struggle to capitalize on the full potential and insights of their data. How can you make advanced analytics work for you and gain competitive advantage? For the past couple of years, chemical companies have
This is my Pi Day post for 2021. Every year on March 14th (written 3/14 in the US), geeky mathematicians and their friends celebrate "all things pi-related" because 3.14 is the three-decimal approximation to pi. Most years I write about lower-case pi (π), which is the ratio of a circle's
This is another in my series of blog posts where I take a deep dive into converting customized R graphs into SAS graphs. Today we'll be working on shapefile maps ... And what data will we be using this time? Here's a hint - the picture below is the Aurora
Collaboration in the cloud is definitely the next big thing from my perspective for life sciences organisations.
Chatbots offer another user-friendly conversational interface to the entire SAS Viya ecosystem, bringing together reporting capabilities, analytics and artificial intelligence.
If you want to hear more about Responsible AI, join the virtual conference “Artificial Intelligence & The Ethics Mandate” on March 16th at 11:00 am CET.
I recently learned about a new feature in PROC QUANTREG that was added in SAS/STAT 15.1 (part of SAS 9.4M6). Recall that PROC QUANTREG enables you to perform quantile regression in SAS. (If you are not familiar with quantile regression, see an earlier article that describes quantile regression and provides
My career path has taken me from the fields on my family farm to the boardrooms of organizations around the world. Starting when I was six years old, my summers involved working with my cousins on the farm from dawn until dusk. From a very early age, I learned the
Fight back against sophisticated money launderers with these 3 techniques.
As delinquencies rise in the wake of COVID-19, lenders must harness technology to orchestrate omnichannel contact strategies.
A key component to make sure that we develop responsible AI is diversity. This is because an AI application reflects and even amplifies the biases of its developers. As I discussed in my previous post, a diverse team will see things from many different points of view and help to
Recently, Microsoft CEO Satya Nadella joined SAS CEO and founder Jim Goodnight for a fireside chat to announce the latest release of the cloud-native SAS® Viya® platform on Microsoft Azure. This new launch was a significant milestone to mark the progress that has been made in our extensive technology and
The recently released 2021 Gartner MQ for Data Science and Machine Learning contains a wealth of information and here are my takes on key market trends from that report for data scientists. This evaluation features SAS Viya with its SAS Data Science offerings.
Data scientist has been on the career hot list for years, but how does one become a data scientist? Well, my journey to becoming a data scientist was not an intentional journey - I didn't start with a plan to end up in a data science career. In fact, I
By making requests through API calls you can expand the functionality of the bots you make with SAS Conversation Designer; allowing your bots to query external sources for up-to-date information, score a model, and many other possibilities. This is very beneficial as SAS Conversation Designer is included in many offerings of the modernized SAS Viya platform, meaning you can easily create bots that are integrated with the other services of the SAS Viya platform or third-party services.
