Corona – what makes US different ?

Posted on April 20, 2020 by swdevperestroika

Yesterday I looked at 50 US states, and how a couple of parameters, population density and GDP per capita, are correlated with the number of deaths.  That analysis revealed that for these 50 states, population density (or more correctly, the … Continue reading →

Wind,Temperature,Air Pressure statistics

Posted on October 14, 2017 by swdevperestroika

The above graphs show statistics from SMHI, the swedish meteorological and hydrographical institute, on air pressure, temperature and wind speed.  For each categrory, (pressure,temp,wind speed) there are two graphs: the first a frequency chart, the second a Q-Q-chart, showing the … Continue reading →

Proof for intelligent design and creationism

Posted on January 5, 2014 by swdevperestroika

As my frequent readers know, I’be been experimenting with neural networks (type of artificial intelligence) over the past couple of weeks. More specifically, I’ve been using neural networks for image recognition. Have a look at the previous couple posts on … Continue reading →

Feeling like God – understanding the design in detail, but not the outcomes: Neural Networks

Posted on January 3, 2014 by swdevperestroika

(First of all, to clarify any potential for misunderstandings: I’m not religious, I do not believe in an almighty God – for that to happen, the teodice problem should have a clear and understandable solution, among other things…) Ok, back … Continue reading →

Neural networks and image recognition – hit rate for target detection

Posted on January 2, 2014 by swdevperestroika

In my previous post, I described some experiments with neural networks and image recognition that I entertained myself with during xmas holidays.  Basically, I wanted to see if I could create a neural network process that, given tiny (10×10, that … Continue reading →

Neural networks and image recognition

Posted on December 29, 2013 by swdevperestroika

I’ve been enjoying xmas holidays doing some machine learning and Neural Network programming, in the general context of ‘Target Recognition’, more specifically, trying to teach my computer how to decide whether a person in an image is male or female. This … Continue reading →

Complexity, Chaos, Organization, Creativity & Innovation: Alan Turing & Benoit Mandelbrot

Posted on September 14, 2013 by swdevperestroika

In this link, there’s a fantastic BBC documentary with Professor Al-Kahlili of University of Surrey, explaining how simple equations and feedback loops lead to the complex and self organizing life forms we are surrended by in our daily lives. Complex … Continue reading →
