Extracting the rules from an ODM Decision Tree model

One of the most interesting of important aspects of a Decision Model is that we as a user can get to see what rules the machine learning algorithm has generated for our data.

I’ve give a number of examples in various blog posts over the past few years on how to generate a number of classification models. An example of the workflow is below.

In the Class Build node we get four models being generated. These include a Generalised Linear Model, Support Vector Machine, Naive Bayes and a Decision Tree model.

We can explore the Decision Tree model by right clicking on the Class Build Node, selecting View Models and then the Decision Tree model, which will be labelled with a ‘DT’ in the name.

As we explore the nodes and branches of the Decision Tree we can see the rule that was generated for a node in the lower pane of the applications. So by clicking on each node we get a different rule appearing in this pane

Sometimes there is a need to extract this rules so that they can be presented to a number of different types of users, to explain to them what is going on.

How can we extract the Decision Tree rules?

To do this, you will need to complete the following steps:

• From the Models section of the Component Palette select the Model Details node.
• Click on the Workflow pane and the Model Details node will be created
• Connect the Class Build node to the Model Details node. To do this right click on the Class Build node and select Connect. Then move the mouse to the Model Details node and click. The two nodes should now be connected.
• Edit the Model Details node, uncheck the Auto Settings, select Model Type to be Decision Tree, Output to be Full Tree and all the columns.

• Run the Model Details node. Right click on the node and select run. When complete you you will have the little green box with a tick mark, on the top right hand corner.
• To view the details produced, right click on the Model Details node and select View Data
• The rules for each node will now be displayed. You will need to scroll to the right of this pane to get to the rules and you will need to expand the columns for the rules to see the full details

OOW : Day by Day blog or Not

Today Sunday is the first full day for Oracle Open World. Although parts of it started on Saturday with the MySQL conference as was as a number of other briefing type session throughout the day and evening.

One thing that I will not be doing over the course of the next 5 days is to give a day by day account of the different sessions that I attended nor will I be giving updates on what was announced at OOW.

There will be plenty of announcements and there will be many thousands of people who will be tweeting, blogging and writing all kinds of articles about the these.

When the conference finishes up next Thursday I will take some time to write a blog post on what were the main announcements for me and in particular for the Oracle Analytics Option and suppose the whole area people call BIG Data.

The first IOUG BIG Data SIG meeting will be on Tuesday morning from 8:45-9:45, Moscone West, Level 3, Overlook 3.

The main presentation on the Oracle Advanced Analytics Option will be on Wednesday by Charlie Berger (Sr Director for Advanced Analytics). In addition to this presentation there will be a number around the whole ORE and BIG Data. This will rounded off by the Keynote on Thursday morning. Yes that is the morning after the big social event on Wednesday night with Kings of Leon and Peal Jam.

One thing that I will be doing each day will be posting a new review of old Oracle Magazine. So check in daily for those.

The next 5 days will be a bit manic as I try to gain learn lots. The problem here is that my interest span a number of areas. OK the main one is the Oracle Advanced Analytics and BIG Data, but I also have DBA and Developer skills/interests too.

Review of Oracle Magazine–May/June 1997

The headline articles for the May/June 1997 edition of Oracle Magazine were focused on the release of Oracle 8, with articles on the new features, how Boeing and Arizona Start University are using Oracle 8 to create a plane for the future, and some articles on using object technology in Oracle 8.

I remember back in 1994 Oracle bought an OODBMS company with the aim of ‘if you cannot beat them then buy them’. The Object Relation project of Sedona was born and the first of the deliverables from the project was in Oracle 8.

Other articles included:

• The key benefits of Oracle 8 Server (The Database of Network Computing) can be grouped under Scalable, Available, Object-Relational, Large Scale, Distributed, Secure and Evolutionary.
• The new features of Oracle 8 have been in new or better functionality for OLTP, Data Warehousing, Parallel Server, Object-Relational (code named Sodona), Partitioning, Backup and Recovery, Connectivity, Replication, NCA Framework and Migration.
• Oracle announces that they have licensed Borland Java tools and we now have the birth of JDeveloper and the world of ADF will come along many years later.
• The Industry Applications Division (IAD) of Oracle announce new applications and releases. These included: Oracle Consumer Packaged Goods (CPG) 2.2, Oracle Government Financials, Oracle Energy 3.1, Oracle Clinical 3.1, Oracle Environmental 4.5 and Oracle Health and Safety 2.0.
• Kumaran Systems, releases a tool that will convert all your reports written in RPT (ReportWriter, which was very similar to PL/SQL) to Reports 2.5.  I really liked RPT. It was quick and you could do a lot with a few lines of code. Converting to Oracle Reports took a bit of getting used to. As a lot of the work you had to put into developing the report revolved you having to play with frames and anchoring box positions. Oh I still have the scares.
• Los Angeles County uses Oracle 7.1 to help it manage its environmental applications.
• How to defined and use Summary tables in your Oracle Data Warehouse.
• Oracle launches a new magazine for its users call Profit and is aimed at the CFO and CIO market.

What to do with your Freebies from Oracle Open World

With 50,000+ people attending Oracle Open World (and associated other conferences) between 30th September and 4th October, and with over 400 exhibitors, there should lots of freebies available.

What do you do with all of these things like pens, pencils, notebooks, memory sticks, t-shirts, pen pots, stress balls, etc. ?

Do many of these items get given away as presents, gives to your colleagues, or at some point end up in the refuge collect, land fill or recycle centre ?

Why not give these items to primary and secondary schools in Africa?

Over the past couple of years I have been collecting some of these kind of things to send out to schools in Africa. What I try to do is to wait until I have enough items that can kit out students in a class with pens, pencils and notepads for a year.

There is no corporate sponsorship of this project that is called Tech Gear for the 3rd World.  I just ask for people to send me their spare items or old corporate items (due to rebranding etc.).  I look after identifying what schools to send the items too, packaging of the items and I pay for the shipping of the parcels to the schools.

So after visiting Oracle Open World you have suitcase full of stuff, or if you are an exhibitor and you have items left over, why not send them to Tech Gear for the 3rd World.

Oracle Magazine Collection

Are you going to Oracle Open World & have old Oracle Magazines.
I’ve been working in the Oracle World for 20 years now. During that time I’ve been collecting the print editions of Oracle Magazine since 1992.
I have all the Oracle Magazines from 1998, but I’m missing some of the editions prior to 1998.

Can you help me complete my collection ?   (I promise that you wont find them on ebay!!)

What I would really like to do is to have a print copy of every Oracle Magazine going back to the very first one in June 1987. To see the electronic version of the first edition, which was very kindly made available by Cary Milsap, click here.

So in the run up to Oracle Open World could you have a look to see if you have any of my missing editions or any of the early editions. I can collect them off you are Oracle Open World.

If you have a look through my blog you will see that I’ve been posting a review of some of the early editions of Oracle Magazine. Ideally at some time in the future I will have a review of all the Oracle Magazines available.
