Why hire Dip: - Worked as machine learning engineer + research engineer + backend engineer.

- single handedly deployed multiple ML system in production

- I believe creating baseline first and improving from it instead of going with biggest weapon.

- fast learner (worked on various project ranging from stitching photos to speech intent detection to solving NP-hard problems)

Why not to hire Dip:

- Need Research Scientist instead of MLE or Research Engineer

- Need senior (experienced) backend engineer

Chaining has its own benefits. But I think this doesn't fit the definition of "Pythonic". Again, "Pythonic" is highly debatable. But, You can always break down big chain of operations, into smaller chain using good variable naming in-between.

Many operations are implemented as iterator in python on list, like filter, groupby. Looking at your code, its looks like you're not doing lazy computation. (Correct me if I wrong). This could be huge performance impact, depending upon use case of list.

I've never worked at a FAANG, too. But main reason I want to work at one is that ability to do project at a scale which is not possible anywhere. Few project are no use for small companies/startups.

For example: Optimizing compile time (no need to invest for extra 1 minute speed up), working on high quality labelled data (i came from ML background, this is not possible in most of startups), analytics on data (questionable ethically), working on Ad platforms, working on large scale system.

In the last, Imagine, even making simple changes have bigger impact on real world.

It might be possible that these people have tried on more platforms (Face recognition APIs) but only reported those where they got good accuracy in terms of defeating system.

I personally would like to see tests done on facebook by uploading these images and checking if it can recognize it.

This is tested on existing models/Face Recognition API which means locked pre-trained models. So, They might have learned way to add pixels such that model outputs very different embedding. This is know issue in deep learning [0][1][2].

I believe, Model trained on cloaked images would defeat its purpose and make this technique useless.

After, reading your comment. I cross checked result and found out that 3 is most optimal size. I even ran fib(40) on it. with size 2, There are many misses but after 3 and on wards misses are constant(if fib(40), then misses are only 40 which emulates DP approach of O(N)).

Why 3 is optimal, because of how recursion and LRU work. I wish i can explain it using animation.

You can play with it. https://repl.it/repls/NocturnalIroncladBytecode#main.py

Yes, I have mentioned DP in my article as just reference. The Purpose of article was to show that how easy it is to implement caching in python using lru_cache decorator which is in std lib. So, We don't have to install any 3rd party lib.

I was able to get the second part of the statement. but I haven't seen the use of "in limit" in a statement like this.

Yes, the universal approximation is a strong claim. NN has been proven to have universal approximation theoretically.

"We show that this architecture gives rise to universal learning capabilities in the limit, with effective model capacity increasing as a function of network size in a manner comparable with deep ReLU networks."

What exactly this statement means?

At glance, It looks like ongoing research of Multi-Task and Meta-Learning will be discussed. Some new tricks on the architecture of NN, Few new methods to train, and some theoretical setting of the area. I will be looking forward to seeing whole series. Maybe share some notes or summary of videos.
