Here I pledge to dedicate 1 hour to coding or learning Machine Learning for the next 100 days!
Day 0: July 06, 2018 Today’s Progress Learned about word embedding in Sequence Models course on Coursera, such as Word2Vec, negative sampling, GloVe word vectors and sentiment classification.
Thoughts It is interesting to know about how the word embedding algorithms are simplified over time while still being able to achieve very good results.
Problem Ethernet RTL8111/8168/8411 is not recognized by kernel 4.4.39-rt50. Running ifconfig shows only the other network interface and lo.
Solution It turns out the realtime kernel does not have module r8168. Instead it contains r8169. However, by installing r8168-dkms the r8169 module is automatically blacklisted. This can be fixed by
sudo apt remove r8168-dkms sudo rm /etc/modprobe.d/r8168-dkms.conf
Today I encountered a weird problem when using Eigen library with keyword auto. The scenario is as follows:
Eigen::Affine3d aff; // aff is assigned with a valid value ... auto r = aff.rotation(); auto res = r * r; In the end, the result variable res contains a 3x3 matrix with only zero values, no matter what values aff has. After a bit of googling, I found out some relevant issues and Eigen documentation: * Eigen auto type deduction in general product * Eigen and C++11 type inference fails for Cholesky of matrix product * Lazy Evaluation and Aliasing
This website is going to be used for all kinds of personal notes and blogs.
