Feb 23, 2020An Impossible AI Challenge?The early results are in! — Last week I posted here on Medium about the Kaggle competition hosted by François Chollet titled Abstraction and Reasoning Challenge. The first “leaders” are on the board now and submissions are evaluated by how they perform on 100 hidden challenges. The best solutions are currently “solving” 1% of these secret…Data Science2 min read
Published in Towards Data Science·Feb 16, 2020An Impossible AI Challenge?François Chollet is looking for a Unicorn — Abstraction and Reasoning Challenge is the title of a just-released Kaggle competition hosted by François Chollet. Sub-titled “Create an AI capable of solving reasoning tasks it has never seen before,” this one is for those truly dedicated to advancing AI. Here’s the problem in a nutshell: You are given 3…Kaggle3 min read
Published in Towards Data Science·Feb 9, 2020What’s a Tensor?Unpacking a common data science structure — The concept of a Tensor was created in 1900 by two Italian mathematicians, Tullio Levi-Civita and Gregorio Ricci-Curbastro, and as is common, they built upon the work of other mathematicians. The Wikipedia page for “Tensor” begins: In mathematics, a tensor is an algebraic object that describes a (multilinear) relationship between…Data Science4 min read
Published in Towards Data Science·Feb 2, 2020Weights, Biases, and BackpropagationA simplified look at some essential components of a neural network. — Neural networks are complex, powerful artificial intelligence (AI) systems that perform tasks such as identifying objects in a photograph or words in live or recorded speech. The name comes from how these systems mimic an aspect of the human brain — a system of interconnected neurons. Many excellent resources are…Data Science4 min read
Jan 26, 2020Bail decisions — Judges or Artificial Intelligence?Musings inspired by Malcolm Gladwell’s latest book — I’ve been listening to the audiobook version of Talking to Strangers, Malcolm Gladwell’s recent book, which I have found utterly fascinating. The topics discussed include how the human preference of “defaulting to truth” has tremendous efficiency benefits but also makes us vulnerable to con-men like Bernie Madoff or abusers like…Data Science2 min read
Jan 19, 2020Adventures in “self-driving” model cars — Week 2In this week’s post, I will go over the parts needed for the build. Last week's post can be found here and is a general introduction to the project. The two major components of this project are the Traxxas LaTrax Rally 1/18 scale 4WD model car and the NVIDIA® Jetson…Self Driving Cars2 min read
Jan 12, 2020Adventures in “self-driving” model cars — Part 1A global race pushing the envelope of what a “self-driving” vehicle can do has been raging for years. Some of the promised benefits include dramatic reductions in the number of vehicle accidents and deaths. While billions of dollars are being spent on R&D by the big players (Automakers, UBER, trucking…Self Driving Cars2 min read
Published in Towards Data Science·Jan 5, 2020Precision, Recall and Predicting Cervical Cancer with Machine LearningAnd what does OSEMN stand for? — Machine Learning is commonly described as a subset of artificial intelligence and in general, involves creating “models” that can analyze data in a variety of ways to make predictions. It has proven itself useful in countless areas, including such commonly known applications as “recommendation engines” that suggest content a user…Machine Learning11 min read
Published in Towards Data Science·Sep 28, 2019Using Keras and TensorFlow to Predict Dengue Fever OutbreaksMachine learning prediction models using time-series weather data. What is Dengue? Dengue, commonly called dengue fever, is a mosquito-borne disease that occurs in tropical and sub-tropical parts of the world. In mild cases, symptoms are similar to the flu: fever, rash, and muscle and joint pain. In severe cases, Dengue can cause severe…Machine Learning7 min read
Published in Towards Data Science·Aug 27, 2019Medical Diagnosis with a Convolutional Neural NetworkA brief look at using artificial intelligence in healthcare. In 2018 the United States Food and Drug Administration approved the use of a medical device using a form of artificial intelligence called a convolutional neural network to detect diabetic retinopathy in diabetic adults (WebMD, April 2018). Medical image processing represents…Machine Learning5 min read
