Feed: SAS Blogs. Author: Byoung-Jeong Choi. 기업이 데이터 기반의 의사결정을 하기 위해서는 AI를 특정 영역이 아닌 분석 라이프사이클 전반으로 확대하고, 이 라이프 사이클은 의사결정 프로세스와 연결돼야 합니다. 개방된 플랫폼에서 분석 시간을 줄이고, 그 결과를 운영시스템에 빠르게 적용해 더 큰 비즈니스 가치를 실현할 수 있어야 합니다. 지난 시리즈에서는 모델링 작업을 위한 피처 자동 생산과 자동 튜닝 정도로 한정하는 일반적인 AutoML과 달리, 데이터(Data)-분석(Discovery)-적용(Deployment)으로 이어지는 분석 라이프사이클 전반을 지원하는 SAS AutoML을 소개해 드렸습니다. SAS AutoML 서비스인 SAS AI-Enhanced Analytics는 더 빠르게 분석을 수행하고 더 빠르게 배포하여 가치가 실현되는 시기를 앞당깁니다. 이후에도 모델을 지속적으로 모니터링하여 성능이 떨어지면 자동 셀프러닝을 통해 성능을 유지합니다. 지난 AutoML ... Read More

Feed: CIO. Author: . It’s not possible to go very far in IT without encountering the term “open source”.

Feed: The Connector by Workato. Author: Jon Gitlin; Sales reps only spend 35% of their time on selling-related activities. The rest of it is likely occupied by repetitive and unproductive tasks, like data entry, searching for information across applications, etc. You can prevent your sales team from performing these time-intensive and less fruitful activities by using sales automation. In the process, you’ll be rewarded with a shorter sales cycle, a higher close rate, and better all-around experiences for your prospects, customers, and employees. So how, exactly, can you perform sales automation? And what are all the benefits you can expect ... 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: Planet MySQL; Author: Kristian Köhntopp; A question to the internal #DBA channel at work: »Is it possible to change a column type from BIGINT to VARCHAR ? Will the numbers be converted into a string version of the number or will be it a byte-wise transition that will screw the values?«Further asking yielded more information: »The use-case is to have strings, to have UUIDs.« So we have two questions to answer: Is ALTER TABLE t CHANGE COLUMN c lossy? INTEGER AUTO_INCREMENT vs. UUID Is ALTER TABLE t CHANGE COLUMN c lossy? ALTER TABLE is not lossy. We can test ... Read More
