Details of Deep Learning data pipelines

Started Jan 26, 2017 0 Replies

I've seen a lot of explanations of modern NN use that are all somewhat abstract. Tutorials usually just do one thing.I don't have a grasp of the exact mechanics of various uses. For example, an image…Continue

Lance Norskog commented on Stephanie Glen's blog post Understanding Covid-19 Statistics (in plain English)
"Generally, humans are immuned after infection by all of the "common cold" Coronovirii (I think there are 4?) for 6 to 9 months. That's why you get it every winter. So, we're looking at yearly meltdowns like this until…"

"At some point VAEX might be what you want: Pandas API for data stored directly in memory-mapped files. https://vaex.readthedocs.io/en/latest/"

"Could this be used to trim useless weights out of deep learning networks?"

Lance Norskog commented on Janardhanan PS's blog post Does "All models are wrong, but some are useful" quote apply to Machine learning models?
"More useful is- "no model is perfect, so you must have a back-up plan". I saw a company deploy face recognition for commercial truck fleets, to verify the driver sitting behind the wheel. The system had no back-up plan for that one guy who…"

Lance Norskog commented on Igor Bobriakov's blog post Top NLP Algorithms & Concepts
"A couple of points: 1) the quality of today's NLP machine translation. Basque is a language isolate, very very isolated, like almost no other language. I just read an article from a Basque newspaper that Google auto-translated. It was very…"

Lance Norskog commented on Divya Singh's blog post How to Discover and Classify Metadata using Apache Atlas on Amazon EMR
"Very good! Needs a little editing, but I think you have an excellent guide to Atlas. I work at a very large retailer and we have a huge collection of tables and data flows that no one person understands, so I've been looking at Atlas and…"

Lance Norskog commented on Stephanie Glen's blog post P-Value Explained in One Picture
"There's so much unaccredited stuff on the net, you know. Maybe sign your stuff, especially when it's this high quality! Do you know of a good explanation of p-values v.s. power? Especially how both help determine whether to act on the…"

Lance Norskog commented on ajit jaokar's blog post Correlation does not equal causation but How exactly do you determine causation?
"My brilliant insight: under information theory, signal and noise are a package deal. People usually measure correlation and infer causality by matching signals. But, if the noise profile for a dependent signal cannot possibly match the noise profile…"

Lance Norskog commented on Bill Schmarzo's blog post Using a Bathroom Faucet to Teach Neural Network Basic Concepts
"But y'know, I suppose it was a valuable lesson in how to be a script kiddie. I've been a script kiddie on a bunch of things since then, like computer audio programming, graphics and now deep learning."

Lance Norskog commented on Bill Schmarzo's blog post Using a Bathroom Faucet to Teach Neural Network Basic Concepts
"We had to write a program to solve this program in freshman programming, circa 1979 at UC Santa Cruz. Of course, we didn't know Runge-Kutta from a hole in the ground and just stole the formula."

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."

Lance Norskog commented on Vincent Granville's blog post Designing better algorithms: 5 case studies
"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…"
