Updating Anaconda

Posted Leave a commentPosted in Practice

Follow these steps to keep your Anaconda installation up to date: Open Anaconda prompt. Typically you can search for this in windows 10, and then open the console (looks like a DOS prompt) Then you can follow the steps laid out here. The link shows how to update all packages in the current environm ent, as well […]

What is TensorFlow?

Posted Leave a commentPosted in Practice, TensorFlow

Think of TensorFlow as a high-performance, easy-to-use framework to perform machine learning. The specific algorithm used for this machine learning is neural networks. But these are not ordinary neural nets. These are a souped-up version, including fancy stuff such as or neural nets. Created by the Google Brain team, TensorFlow provides a user-friendly python front-end, but […]

Classical vs Machine

Posted Leave a commentPosted in Principles

There is a reason why statistical texts spill copious amounts of ink on data sampling and survey designs. Historically speaking, data was incredibly laborious to collect and to analyze with limited computational resources. This led to the development of mathematical modeling techniques that relied on small amounts of information. These models are simplistic and replete […]

What is a model?

Posted Leave a commentPosted in Principles

A model in the context of predictive modeling is simply some useful mathematical abstraction of reality. A model should be (a lot) less complex than the reality it is intended to represent. This might seem obvious, but with ever increasing computation at our finger tips we need to carefully assess the relative complexity of our […]
