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."

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?
3/
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:

In July 1969 the Apollo 11 astronauts conducting several tasks during extravehicular activity (EVA) operations on the surface of the moon. The EVA lasted approximately 2.5 hours with all scientific activities being completed satisfactorily. #OneGiantLeap

#Apollo11 landed on the Moon on July 20, 1969.

That's #OneSmallStep for [a] man, #OneGiantLeap for mankind.

Thanks to @turo I'm renting a #TeslaModel3 during my visit to Silicon Valley - certainly a different experience than traditional #carrental agencies #future #zeroemission #electriccars
Gone to Tesla's HQ in Fremont, California to try the supercharging there. It's supposed to be much faster than before.
I had hoped the Model 3 would charge at the new rate but it didn't happen

Giacomo Rizzolatti - I segreti dei neuroni specchio?

La loro scoperta sta suscitando clamore non solo in campo medico. Il motivo lo spiega il neuroscienziato Giacomo Rizzolatti.

C'è sete di tecnologia da parte dei colossi dell'#AI. In un'ottica d'interazione/integrazione con quanto già realizzato da #Alphabet (#DeepMind), holding che controlla Google, il gigante dei #BigData produrrà in casa i chip (perché farlo fare a terzi?🕵️‍♀️).

Our new #Corl18 paper:

How curiosity-driven autonomous goal setting enables to discover
independantly controllable features of environments

Imagine a robot perceiving a scene through low-level pixels.

It has no prior knowledge of its body (it only knows it can send numerical
numbers as motor commands that produce unknown movements of unknow body parts)
It also does not know that the scene is composed of "objects". Yet, around it there are several objects: some of them can be controlled, others not (distractors)

How could it discover and represent entities, and find out which ones are controllable (and learn to control them)?

Just about to kick off the keynotes at #ODSCWest - also to come today: job fair, hands-on workshops & networking. First speaker: @karpathy
Key element of #AI is that neural networks are code. It's just written by machines - #Code2point). Still need to be maintained, develop tests, refactoring and organization. #ODSC
Need to set up unit tests for #AI neural networks. How to meet tests, tune dataset, tune model, tune optimization. #ODSCWest

1. Let's talk about trinary ( #ternary ) and #IOTA . (Long rant, maybe better suited for a blog entry. Oh well, whatever.)
2. In my many discussions with many different people about #IOTA , ternary is I think the most controversial aspect of the tech. Many people consider it genuine lunacy, a sign that #IOTA is just a scam cryptocurrency.
3. And I'll be honest with you: when I first encountered ternary in #IOTA , I went "What the f*** is this sh**? Numerology?"

OK people. I'm live tweeting @neo4j's #Chicago #GraphTour event today.
We are currently in the keynote. The speaker is talking about how popular Neo4j is
Keynote now telling us about all the new Neo4j features. Examples: location filter, including 3d. Auto cache reheating. I'm interested to know if auto cache reheating is working with query patterns or meant to replace them or what

How many random seeds are needed to compare #DeepRL algorithms?

Our new tutorial to address this key issue of #reproducibility in #reinforcementlearning

PDF: arxiv.org/pdf/1806.08295…

Code: github.com/flowersteam/rl…

Blog: openlab-flowers.inria.fr/t/how-many-ran…

#machinelearning #neuralnetworks
Algo1 and Algo2 are two famous #DeepRL algorithms, here tested
on the Half-Cheetah #opengym benchmark.

Many papers in the litterature compare using 4-5 random seeds,
like on this graph which suggests that Algo1 is best.

Is this really the case?
However, more robust statistical tests show there are no differences.

For a very good reason: Algo1 and Algo2 are both the same @openAI baseline
implementation of DDPG, same parameters!

This is what is called a "Type I error" in statistics.
