(Published on The Suburban’s website, 2021-7-28) The other day, I was looking for a set of earbuds, you know, the ones that come with Apple iPhones and have a microphone built in to one of the earphone cords. My latest iPhone no longer has an earphone jack, and I needed…
Read moreWhy shaft drive motorcycles have lighter handling
When people review motorcycles, they often mention how “light” certain bikes feel, even if they’re on the heavier side. BMW is a brand people bring up a lot; Moto Guzzi riders are super loyal to their bikes, and the Honda Gold Wing has a ton of fans too. Reviewers are…

This Letter to the Editor was published in the Montreal Gazette on 2018-11-16. Re: “The new Champlain Bridge won’t be ready on time” (Montreal Gazette, Oct. 26) Over the past couple of years, I’ve observed the construction of the new Champlain bridge when I’ve crossed by bicycle from Westmount to…
Read moreFree transit would make city more livable
The following was published as an opinion piece in the Montreal Gazette, on 2017-11-14: I am excited by Valérie Plante and Projet Montréal’s election promise to improve public transportation in Montreal, and am sure that it will generate many excellent proposals. Here’s one that deserves attention: free public transportation. Let’s…
Read moreHammingNN classifier: results with various datasets
2012-12-19 This table presents results of using the HammingNN classifier with a variety of publicly available datasets that are frequently used for development and testing of classifier paradigms. For comparison purposes, I’ve included results from 3 other classifier paradigms. Note: you may need to widen your browser window to view…
Read moreHammingNN: a neural network based pattern classifier; results with genomics datasets
As a medical student in the early 1980’s, I was very excited when we were introduced to the physiology behind neurology. Having previously graduated in Electrical Engineering (Waterloo, 1970) and with several years of work experience in computer systems engineering, I immediately saw the potential for modeling neural networks using…
Read moreHammingNN: a neural network based nearest neighbour classifier
I made a presentation about my classifier to Emily Coffey, at the time a PhD candidate in the Cognitive Neuroscience Lab at the Montreal Neurological Institute, and her colleagues, on 2011-1-21. Download a pdf of the presentation slides and notes.
Read morehammingNN progress report
Since my medical school days, I’ve been mulling over some ideas for artificial neural networks that adhere more closely to the physiology that I studied. Over the past couple of years, I finally implemented those ideas, using the Forth programming language on a Macintosh. The process went considerably faster than…

Henry Olders, MD, FRCPC Douglas Hospital Verdun, Quebec, Canada 2 Oct 1990 Introduction Effect of medication on negative symptoms An NIMH double-blind, placebo-controlled study of the effects of antipsychotic withdrawal (four weeks drug-free) followed by four weeks’ treatment with fluphenazine HCl in 19 young patients with chronic schizophrenia showed that…
Read moreHammingNN classifier – early ideas
Below is an article I wrote in 1989, describing my ideas for a neural network derived from my knowledge of physiology from medical student days, my studies in behaviour from psychiatry residency and practice, and computer principles from my time in engineering. A Neural Network Model Based On Brain Physiology…
