Comments Off on Ian Ozsvald: “Creating correct and capable classifiers” at PyDataAmsterdam 2018, Python, by admin.
This weekend I got to attend PyDataAmsterdam 2018 – this is my first trip to the Netherlands (Yay! It is lovely here). I gave an updated talk on my earlier presentation for PyDataLondon 2018, this time I spoke more on :
- YellowBrick‘s ROC curves
- SHAPley machine learning explanations
- Along with my earlier ideas on diagnosis using Pandas and T-SNE
I had a lovely room, wide enough that I only got a third of my audience in the shot below:… Read the rest

Comments Off on Martin Fitzpatrick: Brown Note, Python, by admin.
Relieve your creative blockages with these interactive desktop reminders.

Comments Off on Data School: Best practices with pandas (video series), Python, by admin.
At the PyCon 2018 conference, I presented a tutorial called “Using pandas for Better (and Worse) Data Science”. Through a series of exercises, I demonstrated best practices with pandas to help students become more fluent at using pandas to answer data science questions and avoid data science errors.
I split the tutorial into 10 videos. The first video introduces the tutorial and the dataset, and the other nine videos contain the exercises that we discuss. I recommend that you … Read the rest

Comments Off on Stack Abuse: Implementing LDA in Python with Scikit-Learn, Python, by admin.
In our previous article Implementing PCA in Python with Scikit-Learn, we studied how we can reduce dimensionality of the feature set using PCA. In this article we will study another very important dimensionality reduction technique: linear discriminant analysis (or LDA). But first let’s briefly discuss how PCA and LDA differ from each other.
PCA vs LDA: What’s the Difference?
Both PCA and LDA are linear transformation techniques. However, PCA is an unsupervised while LDA is a supervised dimensionality reduction … Read the rest
