When working with the Clustering algorithms, and particularly k-Means, in the Oracle Data Miner tool there is no way of seeing how compact or dispersed the data is within a cluster.
There are a number of measures typically used in various tools and algorithms, but with Oracle Data Miner we are not presented with any of this information.
But if we flip from using the Oracle Data Miner tool to using SQL we can get (more...)
Yes you read the title of this blog post correctly!
Recently I was doing a bit a clear out and I came across a CD of the UKOUG Conference proceedings from 1999. That was my second UKOUG conference and how times have changed.
The CD contained all the conference proceedings consisting of slides and papers.
Here are some familiar names from back in 1999 who you may find presenting at this years conference, some you (more...)
If you are a user of the Oracle Data Miner tool (the workflow data mining tool that is part of SQL Developer), then you will have noticed that for many of the algorithms you can specify a Case Id attribute along with, say, the target attribute.
The idea is that you have one attribute that is a unique identifier for each case record. This may or may not be the case in your data model (more...)
Finally, I found something that I was looking for a long time, thought is would be very useful. A simplified maze of #MachineLearning #Algorithm feeling like Nirvana Today #MachinesWouldRuleWorld #AdvanceAnalytics
Hope this helps

“Superior Data Analytics is the antidote to Business Failure”
The Oracle 12.2c Database has been released and is currently available as a Cloud Service. The on-site version should be with us soon.
A few weeks ago I listed some of the new features that you will find in the Oracle Data Miner GUI tool (check out that blog post). I'll have another blog post soon that looks a bit closer at how the new OAA features are exposed in this tool.
Have you ever been faced with having to generate a data set in the format that is needed by another analytics tool? or having to generate a data set in a particular format but you don't have the software that generates that format? For example, if you are submitting data to the FDA and other bodies, you may need to submit the data in a SAS formatted file. There are a few ways you can (more...)
In this 5th blog post in my series on using the capabilities of Oracle Text, Oracle R Enterprise and Oracle Data Mining to process documents and text, I will have a look at some of the machine learning features of Oracle Text.
Oracle Text comes with a number of machine learning algorithms. These can be divided into two types. The first is called 'Supervised Learning' where we have two machine learning algorithms for classification type (more...)
Last Thursday evening (20th October) we had our first Meet-up event for OUG Ireland.
Up to recently we have had a one or two full day SIG events that covered both the Tech and BA/Big Data areas. But we have been finding it increasingly difficult to get speakers and attendees to take a full day out of work to attend the SIG events. This was particularly true for a SIG event we had scheduled to (more...)

With my recent role as CTO/Advisor with www.analytos.com, during most of my conversation with Analytics leaders within the company, all are concern over security. At a recent conversation with another entrepreneur friend, one of his solution was stalled due to SQL injection issue on the cloud ( a valid concern , but is it valid ?) .
During my recent startup sting, cloud Allergy word was coined, and it did make sense, because allergies do exist and (more...)
