Risk Avoidance Spectrum and Character Types

Ever since I started following stocks again, I have been preoccupied with developing a "game plan" to help prevent me from making emotional investment decisions.  Plans can be improved.  What I have come up with so far is a stress avoidance model to study how different character types might perform in relation to the market.  Since quite a number of investors are actually algorithms - and many trades are algorithmically triggered - the concept of stress needs…

Namara Dataspec: Monitor the Health of Any Data

Anyone who has worked with datasets that change over time has felt the pain and frustration when the data or schema updates at the source. Maybe you have relied on a scraped dataset to generate a business report or to feed crucial data into an app, then suddenly one column goes missing, another becomes largely blank, and yet another changes its type entirely.

When a dataset is dynamically updated it can, and often will, change without warning, and in ways that cost time, energy, and…

Deep Learning Explained in 4 Simple Facts

Yesterday, I talked about Machine Learning, and the huge impact it will have in the world in the future. Today, I’d like to talk about a similar paradigm, that often gets mixed up with it, but that is not the same thing at all. I’m talking about Deep learning.

First off, let me say: this topic is vast. In my article, I’ll try to boil down the main facts, but be warned, you should investigate the matter on your own to learn more.

Hope I can set…

K-Nearest Neighbors (KNN): Solving Classification Problems

Originally posted by Michael Grogan. 

In this tutorial, we are going to use the K-Nearest Neighbors (KNN) algorithm to solve a classification problem. Firstly, what exactly do we mean by classification?

Classification across a variable means that results are categorised into a particular group. e.g. classifying a fruit as either an apple or an orange.

The KNN algorithm is one the most basic, yet most commonly used…

Studying Risk-based Algomorphology Using Thunderbird Charts

I recently wrote about a stock trading approach that I call skipjack: it allows the user to trade directly from special charts by exploiting skipjack waveforms and formations.  I mentioned that I use an application - a simulation environment - to trade from these charts.  Below I present a screenshot of SimTactics, the application that I created to support this simulated trading.  To the right is a notepad containing four trades generated by an autopilot…
