In previous blog posts, I described how you can create a question and answer application using LangChain and the Oracle Cloud Infrastructure (OCI) Generative AI service. With the Oracle Database 23ai release, we looked at the power of AI Vector Search. This no-cost, built-in database feature provides another alternative to create Retrieval Augmented Generation (RAG) applications using just PL/SQL. However, both solutions require a good amount of code. With the recent availability of the OCI Generative AI Agents service, you can rapidly create a RAG application using low code!

Now that I caught your attention, I hope the image isn't too triggering. I grew up learning to fear these little black monsters that potentially carry a load of Dengue virus that could make you really sick. As recently reported, the disease continues to be an issue in Singapore. During my undergraduate years, I was deeply passionate about viral diseases, and spent a few months in the laboratory learning to characterize the structural components of the virus using cyrogenic electron microscopy. Hence, when Luc Demanche challenged me again to demonstrate retrieval-augmented generation (RAG), I decided to collect and use a few recent articles (PMIDs 38140548, 37478848, 37114191), and use them to create a quick proof-of-concept Oracle APEX application that allows the user to ask questions about the disease. These articles cover topics on the Dengue virus, its genomics and ultrastructure, and progress in vaccine development.

This has been one of those weeks where I couldn't wait to wake up and get to work. Just last week, Luc Demanche threw me a challenge and asked that I help develop an Oracle APEX application that could be used to predict the winner of the Rugby World Cup 2023 (RWC2023). I couldn't resist the challenge!

One of the key highlights at Oracle Cloudworld 2023 is general availability of Select AI feature that allows anyone to query the Oracle Database using natural language. This is likely made possible with a template wrapping the database metadata with the prompt, and then calling either the OpenAI or Cohere APIs to generate the intended text.

Doug Gault had suggested a while ago that I could bring more awareness to the Oracle APEX Challenge Coin project if I had an Oracle APEX application that plots the location of each sponsored coin on a world map. I agree. However, aside from a lack of time, I had also wanted to find interesting ways for awardees to submit their claim of ownership. Over the last week, I had worked on making this dream of a "claims" map a reality with the use of the Oracle Cloud Infrastructure (OCI) Vision AI service, more specifically, its custom model training feature.

Here's an early preview of the claims process in the Claim My Oracle APEX Challenge Coin application.

I'm finally finding more time, post-conference, to catch up on my writing. In this latest post, I'd like to talk about a presentation that I did at Kscope23, "Solving Everyday Problems with the Oracle Cloud". During the session, I had described and demonstrated how we can use the Oracle Cloud Infrastructure (OCI) AI services and Oracle APEX to build compelling solutions, even for personal life challenges.

When I was first introduced to generative adversarial networks (GANs), I was impressed, but yet not impressed. The concept, performance, and outcomes of these advanced machine learning (ML) algorithms were truly jaw-dropping, but easily abused. And so, when everyone was excitedly chatting about ChatGPT, I was cynical and tried to tune out until I came across a comment by an old acquaintance, following a news article on concerns about ChatGPT and potential plagiarism in school.

It's like someone using a calculator in an arithmetic exam, ChatGPT is just another tool.

That statement got me rethinking my stance on the technology, and curious about its utility in my day-to-day job.

It's been too long since I last posted anything on my blog. Thanks to Tim Hall, I am writing again, after a long pause, to celebrate Joel Kallman Day 2022. My contribution today is about my deep appreciation for the team behind the Oracle Cloud Infrastructure (OCI) AI Services. Below is a quick scoop on how I have used these services to improve on my OCI-powered e-flashcard for learning new words in a different language. I will be doing a quick demonstration (session LRN3673) of this work at the upcoming Oracle CloudWorld 2022.

During a recent Kscope21 session, "Predict Customer Churn Using Oracle Autonomous Database, Machine Learning, and APEX", I had shared that it has always been my personal desire to create web applications that are not only purposeful, but also have an element of "intelligence". With new features recently introduced in the Oracle Machine Learning product offering, it is now relatively easy to introduce ML as a component of your Oracle Application Express (APEX) applications. This is the first of several posts that I am writing as a follow up to the presentations I did at this year's (virtual) conference.

The Oracle Cloud Infrastructure (OCI) is a great platform in many ways. However, as much as I love it, I have long griped about the lack of out-of-the-box support for AI services that many of Oracle's competitors have. Well, as of May 6, 2021, I am glad to see that things are starting to turn around with the launch of the OCI Language service.

I was very excited to get my hands on a copy of Mahout in Action. Artificial Intelligence and Machine Learning are my most favourite subjects in Computer Science. Back during my school days, AI and ML were primarily used in research, and sometimes banks use them for fraud detection. I am glad that it is gradually being adopted in mainstream businesses with the help of easy to use frameworks like Mahout, backed by commodity distributing platforms like Hadoop.
