Feed: Actian. Author: Pradeep Bhanot. Abraham Lincoln is quoted as saying, “If I had 8 hours to chop down a tree, I would spend 6 sharpening my axe.”  Spending 75% of the allotted time on preparation may seem like a lot, but in fact, most industry observers report that preparing data for business analysis or machine learning is indeed 70 to 80% of the time spent by data scientists and analysts.The data preparation pipeline consists of the following steps Access the data. Ingest (or Fetch) the data. Cleanse the data. Format the data. Combine the data. And finally, Analyze the ... Read More

Feed: Planet MySQL; Author: Kristian Köhntopp; MySQL uses connection and config parameters from a number of possible sources. The easiest way to find out where it is looking for config files is to run $ mysql --help | grep cnf order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/my.cnf /etc/mysql/my.cnf /Users/kkoehntopp/homebrew/etc/my.cnf ~/.my.cnfAs can be seen, my version of the MySQL client checks in this order /etc/my.cnf /etc/mysql/my.cnf /Users/kkoehntopp/homebrew/etc/my/cnf ~/.my.cnf The cnf file is a file in dot-ini syntax, so you have [groups] and each group contains lines with key = value pairs. Which groups are read? $ mysql --help | grep "groups are" ... Read More

Artwork by Allison HorstAs we all begin the fall planning and budgeting season, everyone I know is feeling a lot of uncertainty. I think that’s natural; after all, many of us still don’t know when we’ll be able to: Return to work in an office. Send our children to school five days ... Read More

Feed: Recent Announcements. In these courses, expert instructors discuss how to build a modern, greenfield serverless backend on AWS. Learners will explore how to build an API-driven application using Amazon API Gateway for serverless API hosting, AWS Lambda for serverless compute, and Amazon Cognito for serverless authentication. You will also get hands-on experience in guided labs as you review different configurations for Lambda and study how to create and manage Lambda functions. You will also learn how to optimize APIs throughout the entire serverless workflow using AWS services in your choice of Java, Node.js, or Python. These new self-paced digital ... Read More

Feed: Microsoft Azure Blog. Author: Rohan Kumar. We live in demanding times, and change is happening faster than ever before. Data has always provided important insights into changing contexts, but to navigate the rapidly evolving landscape, adding layers of intelligence where AI advances decision making and applies predictive analytics at the edge to unlock new possibilities is pivotal. At Microsoft Ignite, we shared a number of announcements to help organizations rebuild in a changing world. Following the announcement of Azure Arc in November 2019, we are announcing the preview launch of Azure Arc enabled data services. With this preview, customers ... Read More

Feed: Planet PostgreSQL. I've been digging a little bit into PL/Python recently-inspired by our recent launch of Crunchy Bridge: a multi-cloud Postgres service with PL/Python and PL/R built right in. One thing that has tripped me up a few times is how PostgreSQL data types work with Python - especially when using external packages like NumPy or SciPy. Data type mapping is something you'll deal with when working with different languages or trying to get separate systems to talk to one another. Mapping types isn't just related to PL/Python, in fact one colleague once wrote a program to interoperate from Ruby ... Read More

Feed: R-bloggers. Author: Jakub Wiśniewski. Version 0.2.2 is out and it has big changes! TL;DR Some new functionalities were added in R package fairmodels which is available on CRAN. In this blog, I will cover them in depth. The biggest changes concerned the fairness_check() function, parity_loss, and the addition of a new plot (not really but it hasn’t been properly introduced). Problem The boundary between fair and discriminatory decision is really arbitrary and subjective. Let’s say that people from towns A and B are identical and the amount of people applying for loans is big and equal in both towns. Can ... Read More

Feed: SAS Blogs. Author: Paata Ugrekhelidze. When I first started building predictive algorithms, I was solely focused on increasing the model's accuracy. I have steadily learned more sophisticated algorithms and how to manipulate training data to better fit the model and better represent real test cases. As problems become more sophisticated and the amount of data increases, the learning frameworks that handle distributed training become more important. Having a model to solve a task is great, but for it to be truly useful, we must deploy it where it is needed. However, this is not simple, because model deployment requires ... Read More
