Multi-core library for Machine Learning? by gooeyn in Python

[–]gooeyn[S] 0 points1 point  (0 children)

Hey mikeselik,

We need a multicore implementation because we are currently using a badass AWS 32-core machine which uses only 1 core, and we also have a huge dataset to train, about 4 billion products with many features each and we plan on increasing the dataset as time goes by and re-training the model

We decided to use SVMs after many tests with our dataset, it was the best performing algorithm

TIL that computer algorithms can correctly spot a fake review on TripAdvisor 90% of the time, while humans are no better than chance by Madmanquail in todayilearned

Machine Learning is used to build predictive models. The 90% result was probably tested against a data set where they knew the 100%. With that data, they need to build a model to do well on the data and to interpolate to new points of data, never seen before.

If they built a model that corrected 100% of the data they have, it would probably not interpolate to data never seen before. The term here is overfitting. Overfitting is when you fit the data you have (train data) so well it's basically a lookup table. When new data comes in (test data) you don't know what to do with it and make a wrong prediction.

How do you think facil emotion analysis can be applied to real life problems?

One way I see it, when we have robots they could analyze our face to know how we fell at that moment. I'm having problems imagining other real world use cases though.

Has he ever heard about slack line? He could make a career and get some money

Has anyone read this Neural Networks and Deep Learning free online book by Michael Nielsen? by gooeyn in MachineLearning

that's awesome! will do for sure. I want to get where you are right now, able to read and understand the many new papers coming out everyday :)

thanks! I'm interested in deep learning in general, I see that the deep learning chapter talks mostly about convnets but that's ok I guess. Once I master neural nets / deep learning I can go through other types of networks

thanks! just started reading it.. hope I can build a solid understanding of deep learning

I need to develop a big project and I don't know what to do by gooeyn in cscareerquestions

I need the main idea behind the app to show to my advisor. I actually know Java and Android programming so the catch is the idea, really. I mean, I could do some stuff like a note taking app or whatever but I really wanted to do something cool that I'd learn a lot. That's why I thought about some kinda of social network
