Evaluating Cluster Dispersion in Oracle Data Mining

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...)

Another Thanksgiving Email

Here is another email we got Wednesday from a Dodeca Excel Add-In for Essbase customer.  This customer has a lot of VBA macros running some automation with Essbase and asked for some assistance.  We told it was as easy as replacing they Essbase function declarations file with our Dodeca Add-In  function declarations file, and then setting the variables that contain the location for the Dodeca-Essbase server.  In other words, replace this file:

Happy Thanksgiving (Featuring an Email That I Am Thankful For)


I get tons of email every day and often have hundreds of emails that have to track on a daily basis which explains, in part, my absence from doing recent blog entries.   Most of the emails I track are sales and support relating to Dodeca.  After all, with Dodeca, the buck stops here, right?  I also get some spam in the mix.  Sometimes, there is an email that really makes my day.  Here is (more...)

Using the Identity column for Oracle Data Miner

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...)

New OAA features in Oracle 12.2 Database

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.

Self Service Business Analytics is great but there is more.

Last week I read an article from Bernard Marr about why #SelfService #BI, #Analytics and #Reporting might not be such a good idea. There is a growing need with Business Users to do things themselves. The world is changing fast and there are situations where people want to act quickly to stay ahead of the … Continue reading "Self Service Business Analytics is great but there is more."

Creating and Reading SPSS and SAS data sets in R

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...)

Oracle Text, Oracle R Enterprise and Oracle Data Mining – Part 5

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...)

Our first OUG Ireland Meet-up

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...)

Oracle Data Miner (ODMr) 4.2 Repository Upgrade

With each new release of the Oracle Data Miner (ODMr) tool (part of SQL Developer) an upgrade of your ODMr Repository is needed. This is because of the numerous new features in the tool. This is particularly the case with ODMr (SQLDev) 4.2.

No most of the new features for ODMr 4.2 will not be visible until you are running a 12.2 Database. But a small number of new features are available (more...)

OTN Appreciation Day : My favourite thing from OTN #ThanksOTN

This blog post is my contribution to the OTN Appreciation Day, the brain child of Tim Hall (read his blog post here).

For my contribution, I'm going to write about something that is a bit different to what most people will be writing about. Most people will be writing about some feature of the Oracle Database or maybe their favourite tool.

I'm not going to do that. What I'm going to write about (more...)

OTN Appreciation Day : Dual Table

I have been working with Oracle products for about 20 years now. One of the great things about Oracle is the Oracle Community. Central platform within this community is the Oracle Technology Network (OTN). I have been frequenting OTN loads of times (downloading software, exchanging knowledge on the forums, etc. ). A lot of people … Continue reading "OTN Appreciation Day : Dual Table"

Oracle Data Miner 4.2 EA : New Features

A couple of weeks ago during the madness of Oracle Open World there was some new product releases and lots of updates to existing products.

One such product was SQL Developer. They released an Early Adopter version (EA1). This is where you can try out the new version of the product, but you need to be careful as it is not the GA/Production version. So it may have some "features".

One component of SQL Developer (more...)
