DAY 1: Python Installation on Windows.

Let start our 30 days journey of Twitter Python Training with:
* How to Install Python.
*Likely issues to faced after the installation of Python.

#TwitterPython #Python #ML #DL #AI #DataScience
I will like to talk about two ways of Installing and running Python on your personal computer and the method I 'prefer' out of the two.

1. Direct Installation from Python Website
2. Installation from Anaconda Website.

#TwitterPython #Python #ML #DL #AI #DataScience
1st Method:
Direct Installation from Python Website

Installing Python on your PC is not a difficult task.
It involves just a few simple steps:
a. Download binaries from
b. Install the binaries
c Add Python to system environment variables
d. Install pip

From a recent @martin_casado article posted on @a16z:

"Cloud infrastructure is a substantial – and sometimes hidden – cost for AI companies".

I'm sharing the techniques we use at @FloydHub_ to reduce this cost on #AWS and improve our gross margins [Thread] #ML #AI
0/ Not all AWS regions are priced the same. GPUs can be up to 90% more expensive across regions. Other than cost consider these when picking your AWS region: proximity to your geographical location, compliance requirements, and integration with any existing AWS infrastructure.
1/ Reserve your GPU instances and/or purchase Savings Plans. Review your GPU usage for the last 3-6 months and purchase 1-year plans based on that. Gives you 25-30% savings on your GPU bill.

Having reviewed a bunch of radiology papers lately with the same flaws - some #ML but most not - here are my top 10 tips! #AcademicChatter #radiology #AI
1/ Start with what is already known, where is the gap in knowledge and why it's important. Some papers are doomed from the start because there is no clear impact of the work. Remember the reviewer may not be super-specialised in your research niche.
2/ I need to understand the experimental design quickly, so a flowchart is really helpful. Put yourself in the shoes of a first-time reader. If the design is easy to follow then everything else fits into place.

1/13 Hoje irei falar para vocês sobre dois conceitos que são menos independentes do que parecem para alguns: Causalidade e predição. Confesso que é até estranho tratá-las como duas coisas separadas, ou diferentes, e espero convencê-los ao... #IA #AI #ML #causality #bookofwhy
2/13 final dessa thread de que essa visão é fundamentada. Na década de 50, Jacob Yerushalmy realizou um estudo onde acompanhou 15 mil crianças da região da baía de São Francisco. Para surpresa de Yerushalmy, e contrariando o que já se mostrava forte na época (que fumar
3/13 fazia mal a saúde), seus resultados indicavam que bebês de mães fumantes nascidos com baixo peso tinham mais chances de sobreviver do que bebês de mães não fumantes nascidos com baixo peso. Não era um estudo de inferência causal, era apenas predição, alguns podem dizer.

How To Train Interpretable Neural Networks That Accurately Extrapolate From Small Data. Today we released a new paper that showcases how to do just that using Scientific Machine Learning (#sciml) techniques to encode non-data scientific information.…
Our approach builds upon the work of @DavidDuvenaud but identifies that the differential equations one works with does not have to be a blackbox, but instead can utilize all of the available scientific models to encode as much prior information as possible.
@DavidDuvenaud This is a structure that we call the Universal Differential Equation: a differential equation with embedded universal approximators. Sometimes neural networks, sometimes Chebyshev polynomials, for us it really doesn't matter because they are small approximators.

Starting 2020 off right by getting the benefit of hindsight & reading some classic papers.

1st up, Take the Con out of Econometrics by Edward Leamer, 1983: all about pros & cons of randomized & observational studies plus answers to many of recurrent #econtwitter, #statstwitter, & #epitwitter arguments & even why #ML can’t do causal inference!
In Part I randomized experiments vs natural experiments, aka observational studies, Leamer provides a nice summary of some of the problems that can arise in RCTs including that randomization guarantees validity *on average* but that chance imbalance can make any given RCT biased

The German Army (Amt für Heeresentwicklung, to be exact) has surprised many and published a position paper on #AI for land-based forces. Will translate bits and comment.
Alright, let's do this!
The paper is available here 👇
It was published only some ten days ago, but was finished in August/September.
#AI #KI #Bundeswehr (1/)…
The first thing to note is that with regard to process, this paper is a bit weird: Germany has a national #AI strategy (which mentions military AI in *one sentence*) but no military #AI strategy for the whole of the Bundeswehr. However, now there is this paper for the Army.

Alors les amis, The French Ministry of Armed Forces #AI task force has released a new report covering #AI in #defence & a roadmap toward more military adoption. You can read it en français here:…

Or read on for a few findings & preliminary thoughts.
FR wants its very own JAIC-like cell, the CCIAD, embedded within their Defence Innovation Agency (IAD). (Shout out: FR speakers should follow @KrajeckiMichael). The Coordination Cell for AI in Defence will facilitate efforts on coordination & strategy. p21 for this buried lede
Nice to see that France does not see AI as an end unto itself. Intro is pragmatic & focusses on the weaknesses of second-wave AI systems (although without using the #DARPA-esque vocab), including by noting that #AI does not change the nature of war.

A "worrying analysis":

"18 [#deeplearning] algorithms ... presented at top-level research conferences ... Only 7 of them could be reproduced w/ reasonable effort ... 6 of them can often be outperformed w/ comparably simple heuristic methods."


[Updates worth tweeting]

There is much concern about #reproducibility issues and flawed scientific practices in the #ML community in particular & #academia in general.

Both the issues and the concerns are not new.

Isn't it time to put an end to them?
There are several works that have exposed these and similar problems along the years.

👏👏 again to @Maurizio_fd et al. for sharing their paper and addressing #DL algorithms for recommended systems (1st tweet from this thread).

But there is more, unfortunately:

Why Python?

A thread as requested by @hackSultan

Will try to make this as unbiased as possible. 😁

Python is a high-level programming language whose structure mimics the way humans think.
It abstracts away low-level stuff like memory management, pointers etc.. which are the main stay of other languages like C++, Java
It is dynamically typed. Don’t be perturbed. Basically when u say a language is statically typed, it means you need to declare your variables upfront. You need to tell the compiler how much memory to set aside to handle a variable in advance.
