Why Python?

Jan 10, 2023

Why Python? Of all of the questions that I have been asked as the instructor of an Enthought Python course, this has been one of the most difficult to answer in a satisfying way. The answers I have given have always seemed more opinion than fact. Still, if someone asks me what language I recommend…

Accelerating Science: the Classical Mechanics Perspective

Dec 6, 2022

When thinking about enhancing R&D processes, Newton’s second law of motion provides the perfect framework. Classical mechanics teaches us that putting a body into motion requires applying force. The resulting acceleration will be the sum of the forces applied to the body, divided by the body’s mass: a = F/m. So, if we want to…

Retuning the Heavens: Machine Learning and Ancient Astronomy

Nov 1, 2022

What can we learn about machine learning from ancient astronomy? When thinking about Machine Learning it is easy to be model-centric and get caught up in the details of getting a new model up and running: preparing a dataset for machine learning, partitioning the training and test data, engineering features, selecting features, finding an appropriate…

Extracting Target Labels from Deep Learning Classification Models

Sep 5, 2022

In the blog post Configuring a Neural Network Output Layer we highlighted how to correctly set up an output layer for deep learning models. Here, we discuss how to make sense of what a neural network actually returns from the output layers. If you are like me, you may have been surprised when you first…

Exploring Python Objects

Aug 1, 2022

Introduction When we teach our foundational Python class, one of the things we do is make sure that our students know how to explore Python from the command line. This has several advantages. First, it reduces context switching – to figure out new stuff, students don’t constantly have to toggle between writing Python code and…

Choosing the Right Number of Clusters

Jul 4, 2022

Introduction When I first started my machine learning journey, K-means clustering was one of the first algorithms I was introduced to – and it is still one of my favorites to this day. I was amazed at how elegant yet comprehensible the procedure was. There is something oddly satisfying about watching the cluster assignments and…

Prospecting for Data on the Web

May 31, 2022

Introduction At Enthought we teach a lot of scientists and engineers about using Python and the ecosystem of scientific Python packages for processing, analyzing, and visualizing data. Most of what we teach involves nice, clean data sets–collections of data that have been carefully collected, scrubbed, and prepared for analysis. While we also mention in passing…

Configuring a Neural Network Output Layer

May 3, 2022

Introduction If you have used TensorFlow before, you know how easy it is to create a simple neural network model using the Keras API. Just create an instance of the Sequential model class, add the number of desired layers and accompanying layer nodes, define the activation functions to be used by each layer, and compile…

No Zero Padding with strftime()

Apr 5, 2022

One of the best features of Python is that it is platform independent. You can write code on Linux, Windows, and MacOS and it works on all three platforms with no problems…mostly. Admittedly there are some issues. Most of these are from known operating system differences when accessing system subprocesses or dealing with various local…
