Why are we going to need a private and custom personal AI

There’s been an explosion after the public launch of ChatGPT, followed by the leakage of the LLaMA weights and the open access to a OpenAI API. LLM’s enabled an incredible amount of applications that couldn’t be done before or at least not with the current level of success. Human language is going to become the […]

Using Rasa NLU for entities extraction (NER)

Detecting taxis from my balcony

[DISCLAIMER] This is a post from 2017 that I’ve recently translated from Spanish to English. [/DISCLAIMER] I’m doing the Deep Learning for Coders MOOC from fast.ai and the exercise in the first week consists on using a script to detect dogs and cats from several images. It’s always nice to apply what you learn in […]

A few resources to get into Deep Learning

Before making some recommendations I’d like to mention that I don’t have the absolute truth, this is simply a path that resonates with me because my personality is geared towards more practical resources. I usually like to delve into theory after I know the basics. Now that I made that clear, these are some resources […]

I have a small dataset…so what?

It’s widely known that one of the higher barriers to train a predictive model using Deep Learning is the availability of a large and proper labeled dataset as it usually carries a high time labeling cost to get it. So we have two high cost tasks right here and before getting to the fancy stage […]

Detección de fraudes con ML desde cero

Hace unas semanas me pidieron un pequeño informe (que no lleve mucho tiempo) a alto nivel de como implementaría la funcionalidad de detección de fraudes usando Machine Learning. Mi aclaración fue de que no soy un experto en el mundo de detección de fraudes y por lo tanto que mi enfoque puede no ser el […]

NLP techniques and the balance between model accuracy and explainability

If you’re working on a NLP related task, you’ll need to decide which approach to take. Before starting building the code a project structure, it’s important for you to define the specific goals of the project in terms of explainability and accuracy. Nowadays the NLP techniques that can offer more accuracy are the ones with […]

Traditional vs. AI software projects: dealing with uncertainty

You have to be prepared to deal with a lot of uncertainty if you want to work on Artificial Intelligence projects. You can estimate and plan a traditional software project, but most importantly, you know that sooner or later, with more or less difficulty, you will end up getting the project built. It’s a deterministic […]
