What is Multimodal AI, anyway?

Clearly, we see this MMAI everywhere nowadays. Enter a prompt in Midjourney and you now get an image. From VQGAN-CLIP who had released her code several years ago to offer the first example of using text prompts to generate images, to, RunwayGen that makes videos (like this 4-sec clip I

A Beginner's Quick Brief to Model Learning

Once I deciphered how a neural network operates and was able to diagram and code it by hand using nothing by numpy, I was hooked. It was as if I finally broke through and could interpret all the complex diagrams I saw on the internet. Shortly after I came to

Easy Statistics for Model Evaluation

Statistics is the tried and true way of evaluating the performance of a machine learning model. I wrote the material below about two years ago when I was in the thick of my PhD. It's a basic overview of many terms you'll hear over and over

Taking a look at "How do Deepfakes Move?"

I read an excellent paper this morning by Demir from Intel and Ciftci from Binghamtom University entitled How do Deepfakes Move? Motion Magnification for Deepfake Source Detection, published at CVPR. They also published FakeCatcher: Detection of Synthetic Portrait Videos using Biological Signals. The paper posits that by analyzing features of

Detecting Deep Fakes

Detecting Deep Fakes

I don't have to tell you that everything we see online nowadays is increasingly suspicious. In our age of Generative AI and jaw dropping Tik Tok filters, it's hard to know what's real or what's fake. Since my dissertation was focused on

Can Language Agents Play RPGs?

Can Language Agents Play RPGs?

I'm getting back into it after a holiday break and one of the most fascinating areas of AI research is Language Agents. I'm more of a computer vision person, so LLMs are not my bread and butter. But, I've grown increasingly interested in the

Lessons Learned as PhD Student

Lessons Learned as PhD Student

Before I defend, I wanted to share my Top 5 Lessons Learned as a PhD Student. If you're thinking about applying for a PhD - especially in computer science (or adjacent) fields - these might pertain to you. However, I think they're relevant for most PhD experiences.
