   My conscious brain: 'We should learn linear algebra to better understand neural networks.'

   My revealed preferences: 'We are going to scroll specifically the parts of Wikipedia that list defunct 19th-century breakfast cereals.'

     @Daojoan Which part of linear algebra are you trying to learn? I love linear algebra. If it’s more the beginning parts: Hit me up if you need help. (I think I have forgotten the advanced stuff, it was in 2002.) The only problem might be that I‘m not familiar with the English-language math terms. But if you want to calculate the eigenraum of a matrix …

     @GreenSkyOverMe We learnt all about calculating the eigenwhatevers in our mandatory linear algebra course, but never why.
