Lance Norskog commented on Capri Granville's blog post Interesting Type of Chart: Hexagonal Binning
"An octagonal-square tesselation has N octagons and N squares, but the octagons have larger areas. This would allow a chart that displays two different quantities per geo point. Like a complex number."

"I know of an IoT vendor which has a face recognizer as part of a fancy dashcam that you put into commercial vehicles. The task of the face recognizer is to decide which driver is at the wheel, of all the drivers that you hired and gave badges to. In…"

Lance Norskog commented on William Vorhies's blog post Causality – The Next Most Important Thing in AI/ML
"I have not seen a basic idea described in the causality literature. Either I'm looking in the wrong place, or I really am another Einstein- but I'm guessing the former. In information theory, signal and noise are a "package…"

Lance Norskog commented on Stephanie Glen's blog post Math You Don't Need to Know for Machine Learning
"Nice! I see a lot of these "how to become a DS" and the one thing I never see is emotional, not intellectual: you must develop a deep, almost religious, reverence for the sanctity of the experiment. To maintain your state of grace, you…"

Lance Norskog replied to Nikita Shanker's discussion How does hive insert into with select work at memory and storage level
"What is the table format? Different table formats require different amounts of memory to create the output HDFS file. Text and Sequencefiles need very little memory. Hive copies data from table2 to a local files on some of the servers, then copies…"

Lance Norskog replied to Andrew Steckley, PhD's discussion The essential characteristics of directed search
"The text search literature addresses this. A text search engine applies a scoring function to every document in the index, and chooses the document with the highest score. Text search indexes are all about pruning low-scoring documents early. "

Lance Norskog commented on Andrea Manero-Bastin's blog post Seven Techniques for Data Dimensionality Reduction
""PCA destroys interpretability" PCA is invertible, since it is just a linear translate+rotate matrix. You can apply PCA, fix the final N columns at their mean, and then invert the altered vectors back to the original subspace. This will…"
