shared thoughts, experiments, simulations and simple ideas with python, r and other languages linear programming is a technique to solve optimization problems whose constraints and outcome are represented by linear relationships. simply put, linear programming allows to solve problems of the following kind: after a lot of fiddling around, i finally built up the circuit for automating the turn on and off of my garden lights. it was about time wasn’it? yeah, i know, it took me some time, but it was worth it since i think the end result is particularly nice and i enjoyed the sized solar panel. the lights should turn on in the evening and turn off in the morning. ideally turn on and turn off should be adjustable below you can find a picture of the circuit simulated in ltspice with all my notes following testing and a close up of the circuit. in this post i’m going to apply pca to a toy problem: the clas*ification of faces. again i’ll be working on the olivetti faces the goal of this post is to fit a simple clas*ification model to predict, given an image, the label to which it belongs. i’m goint to fit two support vector machine models and then compare their accuracy. principal component an*lysis (pca) is a dimensionality reduction technique which might come handy when building a predictive model or in the exploratory phase of your data an*lysis. it is often the case that when it is most handy you might have forgot it exists but let’s this week i finally got to play around a little with some electronic components i ordered and test them before using them on side projects. my goal was to find the iv curve of a 3v 0.5w zener diode i need to use on a project. since i had all the instruments set up, as a bonus i the test circuit i used for the measurements is the following when you learn about the fourier transform and what it can show you about a signal, you immediately start thinking about its possible applications. the fourier transform, however, deals with continuous time signals while, in practice, computers deal with discrete time
