The m = n Anomaly
มุมมอง 866 หลายเดือนก่อน
The strange out of sample behavior of linear regression when the number of training examples is equal to the number of model parameters. Article link: win-vector.com/2024/04/03/the-m-n-machine-learning-anomaly/
How Data Quantity Drives Model Quality
มุมมอง 596 หลายเดือนก่อน
This is a video introduction to my tutorial article on how more data is better in training machine learning models. win-vector.com/2024/04/02/how-data-quantity-drives-model-quality github.com/WinVector/Examples/blob/main/TrainingSetSize/TrainingSetSize.ipynb
Jupyter in a for loop
มุมมอง 958 หลายเดือนก่อน
Quick example of how to render the same Jupyter notebook for different settings of control parameters. Please see here for more details: win-vector.com/2024/02/06/use-jupyter-notebooks-inside-for-loops/

A History of Recent AI
มุมมอง 21411 หลายเดือนก่อน
This is a history of recent AI to help people responsible for decision quality have some terminology and orientation to evaluate AI systems and claims. Slides and links can be found here: github.com/WinVector/Examples/tree/main/decision_intel_ai . A note on AI hallucination can be found here: win-vector.com/2023/11/13/yet-another-chatgpt-winge/

Partial Pooling
มุมมอง 228ปีที่แล้ว
This video is an introduction to the idea of partial pooling: combining data from multiple sources to get lower expected error! For the actual details of how to derive and use the methods in Python, please see here: github.com/WinVector/Examples/blob/main/PartialPooling/PartialPooling.ipynb .
How much data do you need?
มุมมอง 117ปีที่แล้ว
This is an introduction to my article on how much data is needed in data science projects. The full article can be found here: win-vector.com/2023/03/18/how-much-data-do-you-need/ .
Regression Lecture: decomposing out the error and residuals
มุมมอง 124ปีที่แล้ว
This lecture uses ideas and notation from this article: win-vector.com/2023/03/12/thinking-about-linear-regression/ . And, I am trying to have a bit of fun with the setup.
