Visualising AI Embeddings in APEX

" To deal with hyper-planes in a 14-dimensional space, visualize a 3-D space and say 'fourteen' to yourself very loudly. Everyone does it."     - Geoffrey Hinton , 2018 Turing Award winner. Within the wonderful world of  Generative AI , one concept that is all the rage is RAG, or  Retrieval Augmented Generation , which is an  AI framework that combines the strengths of traditional information retrieval systems (such as databases) with the capabilities of generative large language models (LLM s) . RAG's goal is to improve the accuracy, relevance, and timeliness of information  generation  - such as  documents, text and images -  by optimizing LLM output.  When creating a RAG system, it’s essential to store information in a format that a LLM can retrieve. This is where  data is converted into embeddings through a pro...

Oracle Locator and Spatial

If you already use Oracle Spatial or Locator then you probably already know Simon Greeners SpatialDB Advisor blog, but if not then I can recommend it as an invaluable source of Spatial nuggets.  Whether you are just starting out with Spatial or have some level of experience with it you will find something there which will knock your socks off!

When I was helping a client with creating a geo-spatial database I found it confusing with regard to what is included as part of the Locator licence ('free' with Enterprise Edition) instead of the additional fee option of Spatial.  One of Simons posts really makes it clear what is and isn't included with Locator, and thus I was able to ascertain that the client only really needed the functionality available within Locator, resulting in a considerable saving on licence fees for the Spatial extension.

Oracle Select AI and APEX

Image
Yes, yes, I know, it's my first blog post in 10 years.  A s Oracle is doing some really interesting stuff with AI I thought I'd break cover and do a post showing a little something I've been working on. It's probably not escaped your attention that Oracle recently announced the release of Oracle Database 23ai (on OCI/Azure now but not yet on-prem), with a host of new features to allow developers to incorporate generative AI (genAI) into their work which will ultimately help end users be more productive. One AI feature that was released in 2023 prior to this announcement is Select AI , or Autonomous Database Select AI to give it the proper title.   This is a feature of the Autonomous Database that enables data to be queried using natural language, generating (ANSI) SQL from genAI large language models (LLMs) such as  OpenAI,  Cohere and Azure OpenAI.   There's a great  demo put together by the Oracle APEX team demonstrating Select AI working with...

Fun with Bubbles!

Image
I'm on a train up to Liverpool for the UK Oracle User Group Tech 14 conference, and decided it's about time for a post showing something I've been working on.  I don't post often these days, which I blame on work and family commitments, but is probably just down to pure laziness.  Anyhow, I'm feeling in the mood so I'll just get on with it in case the desire to catch some zzz's becomes overwhelming.  Also it takes my mind of the bad coffee served up on the train. So, I've been getting into  D3  a little, which if you don't already know is a JavaScript library for manipulating data to create interactive graphs and charts.  Some of the stuff people are creating using D3 is amazing, including this dynamic bubble chart example.  I thought I would use this example as the basis for creating a bubble chart in Apex, that dynamically updates with some cool transitions, using data from the database rather than the real time API in the example. The demo ca...
