In the second hour of “Connections with Evan Dawson” on May 14, 2025, we’re joined by an AI expert and a member of the New York State Assembly for a discussion about legislation that would regulate AI.

It happened. The decision was made, and the directive has come. You have to ship “AI” in the next quarter or two, and you have to do it right. So now what?

In the second hour of “Connections with Evan Dawson” on Feb. 7, 2025, guest host Matt DeTurck and his guests explore the role of AI in movie relationships.

In the second hour of “Connections with Evan Dawson” on Dec. 23, 2024, we discuss if OpenAI’s o3 and other new forms of artificial intelligence can go beyond the limits of human intelligence.

Apply cutting-edge machine learning techniques—from crowdsourced relevance and knowledge graph learning, to Large Language Models (LLMs)—to enhance the accuracy and relevance of your search results.

Delivering effective search is one of the biggest challenges you can face as an engineer. AI-Powered Search is an in-depth guide to building intelligent search systems you can be proud of. It covers the critical tools you need to automate ongoing relevance improvements within your search applications.

Inside you’ll learn modern, data-science-driven search techniques like:

Semantic search using dense vector embeddings from foundation models Retrieval augmented generation (RAG) Question answering and summarization combining search and LLMs Fine-tuning transformer-based LLMs Personalized search based on user signals and vector embeddings Collecting user behavioral signals and building signals boosting models Semantic knowledge graphs for domain-specific learning Semantic query parsing, query-sense disambiguation, and query intent classification Implementing machine-learned ranking models (Learning to Rank) Building click models to automate machine-learned ranking Generative search, hybrid search, multimodal search, and the search frontier

AI-Powered Search will help you build the kind of highly intelligent search applications demanded by modern users. Whether you’re enhancing your existing search engine or building from scratch, you’ll learn how to deliver an AI-powered service that can continuously learn from every content update, user interaction, and the hidden semantic relationships in your content. You’ll learn both how to enhance your AI systems with search and how to integrate large language models (LLMs) and other foundation models to massively accelerate the capabilities of your search technology.

In the first hour of “Connections with Evan Dawson” on Friday, September 8, 2023, our guests discuss current phone scams involving humans and AI, and what community members need to know.

In the first hour of “Connections with Evan Dawson” on Tuesday, August 1, 2023, we discuss how AI can make teachers’ jobs better or easier.

In the second hour of “Connections with Evan Dawson” on Wednesday, May 3, 2023, our guest explains the difference between different types of artificial intelligence and what he expects for the future of AI.

EBSCO’s Clinical Decisions is committed to providing health care professionals with precise answers to their clinical questions. Achieving a balance between precision and recall can be especially difficult for complex queries. Practitioners expect highly relevant search results but also appreciate supplementary results when appropriate. Our existing Elasticsearch engine and knowledge graph was failing to achieve the desired results for these complex queries, typically expressed as long-form natural language. Join us as we outline our journey to deploy a high-quality vector search solution to production for EBSCO’s DynaMed and Dynamic Health products. We will detail the domain, problem space, previous failed attempts, technology choices, model selection, relevance testing methodology, validation with stakeholders, and rollout to our existing customers.

In the second hour of “Connections with Evan Dawson” on Wednesday, March 22, 2023, our guests discuss perceptions of new technology like artificial intelligence (AI), and the theory of “reverse Scooby-Doos.”

So you want to deploy a large language model, and keep your latency SLA? NLP adds enormous value to customers, but getting it to work efficiently is fraught with uncertainty and high cost. As transformers and other big neural network architectures make their way into your platform, you may be finding it difficult to get the speed and throughput you need within your budget, or even understand why it is so expensive.

This talk will give an overview of the latency and throughput challenges, and how to solve them. We will give an overview in the product and cost implications as well as the technical improvements that can be used to get things running fast. We will compare solutions and help make sense of difficult to understand technology.

The audience will walk away with the information they need to decide on the best direction for inference in their production platform.

Use this playbook as a reference when you migrate to Solr or Elasticsearch, as featured in our talk The Search Engine Migration Circus

Omnichannel merges the digital and physical stores in a seamless experience, and site-search drives that seamlessness.

How much money are you losing or gaining, depending on a site-search query? You need to be able to know if search is working, and you can with these KPIs!

Today we’ll discuss KPIs for the actual product items that are presented to a buyer when they use your site-search.

We will outline all the things you need to know about measuring the quality and effectiveness of your store’s site-search.

You have a search platform installed and working, you’re measuring, experimenting, and improving search quality, but you’re still having difficulty fixing some complicated and annoying problems you still have. In short, you need to level up - do it with Natural Language Search training!

So you need to migrate your search to a different engine or platform.

We unwrap the mystery behind two popular search relevance metrics nDCG and ERR through visualization, and discuss their pros and cons.

This article gives an overview into the opportunities and challenges when applying advanced transformer models such as BERT to search.

105 falsehoods programmers believe about search, a complex field where competence is hard-won through training, practice, and experience.

Welcome, dear reader, to my first OSC blog post. Let’s dive in! While search relevance is often equated with ensuring customers find what they need, that is only part…

A year ago, I created a small demo of animating guilloches as two dimensional graphics on an HTML5 canvas. In this post I revisit the beautiful and elegant patterns as 3d constructs that resonate with sounds from the physical world.

This article outlines the process for porting Andrew Trask’s (aka IAmTrask) 11-line neural network[1] from Numpy (Python) to Torch (Lua).

I’ve documented my progress here, for those who are interested in learning about Torch and Numpy and their differences. As I started from scratch I hope this can prove useful to others who get stuck or need guidance.

Having recently read a blog post on guilloches[1], I became intrigued and the post inspired me to recreate them. They are beautiful patterns, and the starting formula to draw a rosette looked very simple to replicate in an HTML5 canvas. The 30 minute project quickly took off into a several hour excursion into the beauty of animated guilloches.

After some hammock driven development, Harissa is mature enough to release some results. Originally intended for entire videos, I found the process better suited for only several frame remixes, usually of an identical source image.

more

I am slowly working on a side-project that makes a video into a mishmash of circles for each frame. I have an early version running, that manually takes a video, splits it into frames, remixes each frame into the circle mishmash, and recomposes the video with the new remixed frames. The project is called ‘Harissa’. The name Harissa comes from an Armenian dish and is made from chicken and a local type of wheat. It cooks for a long time, until it is a thick porridge. It is a fitting name because fully rendering a video is a slow process, and the result is an interesting mishmash of the original.

It is hard to write a program that invents original art. Two of the main reasons that software cannot create original expressive art are lack of context, and lack of experience.

Software lacks the ability to derive a human-like context from its surroundings. Some trivial examples are not knowing whether a flower is beautiful, or whether satire is funny. Software also does not know how to learn to understand this context, it cannot experience its surroundings in a similar fashion to that of the observer, and therefore cannot relate to the subject nor connect with the observer in any meaningful way.

I’ve finally open sourced Anagramica (http://anagramica.com/)

The code is now available under the MIT license at https://github.com/binarymax/anagramica

I’m not entirely sure why I never open sourced it in the first place. After 25 years of coding I’ve only recently become active in opening my code for others to see and use. I have a cathartic story to tell about a previous project, which I’ve never told anyone about, and silently open sourced this past winter.

I’ve been known to debate about a subject, which I like to call ‘The Idea is Art’. I defend that whatever imagery we can conceive of in our mind can be considered art, even when lacking a physical manifestation.

‘What is art’ has been debated ad infinitum, and some like to draw the line and say something is not art if it cannot be expressed - as art is, by definition, expression.
