The toughest data science interview I ever had

I got bombarded for 45 minutes with theoretical questions:

๐Ÿ”ธ Entropy
๐Ÿ”ธ KL divergence, other divergences
๐Ÿ”ธ Kolmogorov complexity
๐Ÿ”ธ Jacobian and Hessian
๐Ÿ”ธ Linear independence
๐Ÿ”ธ Determinant

Continued ๐Ÿ‘‡

๐Ÿ”ธ Eigenvalues and Eigenvectors
๐Ÿ”ธ SVD
๐Ÿ”ธ The norm of a vector
๐Ÿ”ธ Independent random variables
๐Ÿ”ธ Expectation and variance
๐Ÿ”ธ Central limit theorem

๐Ÿ‘‡
๐Ÿ”ธ Gradient descent and SGD
๐Ÿ”ธ Other optimization methods
๐Ÿ”ธ The dimension of gradient and hessian for a neural net with 1k params
๐Ÿ”ธ What is SVM
๐Ÿ”ธ Linear vs non-linear SVM
๐Ÿ”ธ Quadratic optimization

๐Ÿ‘‡
๐Ÿ”ธ What to do when a neural net overfits
๐Ÿ”ธ What is autoencoder
๐Ÿ”ธ How to train an RNN
๐Ÿ”ธ How decision trees work
๐Ÿ”ธ Random forest and GBM
๐Ÿ”ธ How to use random forest on data with 30k features
๐Ÿ”ธ Favorite ML algorithm - tell about it in details

That was tough!

I think a plausible explanation is that whatever Corbyn says or does, his critics will denounce - no matter how much hypocrisy it necessitates.


Corbyn opposes the exploitation of foreign sweatshop-workers - Labour MPs complain he's like Nigel

He speaks up in defence of migrants - Labour MPs whinge that he's not listening to the public's very real concerns about immigration:

He's wrong to prioritise Labour Party members over the public:

Unfortunately the "This work includes the identification of viral sequences in bat samples, and has resulted in the isolation of three bat SARS-related coronaviruses that are now used as reagents to test therapeutics and vaccines." were BEFORE the


chimeric infectious clone grants were there.https://t.co/DAArwFkz6v is in 2017, Rs4231.
https://t.co/UgXygDjYbW is in 2016, RsSHC014 and RsWIV16.
https://t.co/krO69CsJ94 is in 2013, RsWIV1. notice that this is before the beginning of the project

starting in 2016. Also remember that they told about only 3 isolates/live viruses. RsSHC014 is a live infectious clone that is just as alive as those other "Isolates".

P.D. somehow is able to use funds that he have yet recieved yet, and send results and sequences from late 2019 back in time into 2015,2013 and 2016!
