 Working with clean, well structured binary classification problems is one thing, but being able to manipulate any image data and fine tune the model to achieve the most in the least time is another cake. In this section we will learn some basics of image data sets structures and how to fine tune the model to improve generalization and performance. In doing so we reach winning level performance in a real life problem of wildlife detection in the jungle. Using pytorch and fastai on a real data set The internet is full of tutorials with very curated data sets, here I am going to use a real data set from one site called drivendata, which contain many great competititions to use ML/DL for social and environmental problems.  https://www.drivendata.org/competitions/87/competition-image-classification-wildlife-conservation/page/409/ The goal is here to detect species that are moving, at night... so this is quite challenging but also fun as this is a real problem. I will go through the learni

Preliminary monetary conditions In the following post, we review the necessary tax reform that, complementing the monetary reform explained in  https://alanfortunysicart.blogspot.com/2022/05/steady-state-macroeconomics-monetary.html  should cover the main changes to achieve a steady state economy.  Before we jumped in, let's remember the key changes in monetary policy we are asking for: Stablish 100% reserve banking and limit money creation to central banks Limit the supply of money as fixed as possible, and only increase to finance the transition of a steady state if tax reform take too long Audit debt, by recognizing some % of repudiation and distribute fairly the burden of the costs of repudiation Clarification on interest rates and growth mandate We did not answer the apparent contradiction between low interest rates and high inflation as a driver for growth, when sacred economics claimed that negative interest rates are required for a non growing economy.  Before we jumped int

  It is not all about money Alan , some activists keep telling me, when I try to explain why we are being overloaded of renewable energy projects in our natural environment... or how changing the economic system will allow us to stop doing activism as a firefighter and start becoming part of the hollistic transition we all claim but struggle to define. If uneconomic growth is   the reason why we have a civilization crisis, and money is the medium by which we organize our economic activity, we need to explain the monetary conditions for a steady state economy, or how money works in a economy that does not grow. This monetary system should be define in a way that does not need permanent economic growth, priting money to back up debt payment, costly inflation or unfair risk sharing to thrive. This post is about the changes in our monetary system that are required to reach a steady state economy , or the maximum wellbeing for sufficient people the maximum amount of large but finite time. C
