I can't understand. Any English version? Thanks.

Hello Hunters of the Secret Challenge,

considering the problem with the Slack chat history we decided to create a bitcointalk.org thread where we are going to collect the clues for the secret challenge and/or the links to these clues.
We will also try to gather all useful articles, post's etc. about the secret challenge, which could be a help in solving it.
Dont forget to visit us at our Slack #secret_challenge, Twitter @Peculium and Peculium Facebook page to possibly find new clues!
Additionaly you can join the >> Peculium Bounty campaign << and earn PCL tokens while doing exactly that - a perfect win-win situation!


With this i wish everyone good luck and a lot of fun on the hunt for the 1.000.000 €!!!

Here are the clues that were found so far:


1. The Memristor (Wikipedia)




2. Alessandro Volta (Wikipedia)

Pioneer of electricity and power, who is credited as the inventor of the electrical battery.




Possible link: Nvidia Volta



3. Pinched hysteresis loop / similarity with loop, sine-wave function and "P" from Peculium

The memristor leads to hysteresis. The word means lagging behind. Hysteresis is not only used in physics to describe magnetic behavior, it can also be applied to economics:
When some negative shock reduces employment in a company or industry, fewer employed workers then remain. As usually the employed workers have the power to set wages, their reduced number incentivizes them to bargain for even higher wages when the economy again gets better instead of letting the wage be at the equilibrium wage level, where the supply and demand of workers would match. This causes hysteresis: the unemployment becomes permanently higher after negative shocks.






4. Geometrical patterns

Forecasts: Hysteresis, Time series, ARIMA

5. Quetzal

I UM 3 6 9 E V E





6. Tesla



"If you only knew the magnificence of the 3, 6 and 9, then you would have a key to the universe." - Nikola Tesla




This hardware will be used to create a relatively affordable AI.

--> Volta + Tesla = ?


7. AIΞVE -> EVE = Equilibrium, Values, Ethics

From YouTube: https://www.youtube.com/watch?v=kg2vYFJ_R50
Thanks to AIEVE (Artificial Intelligence Balance Ethical Values), we introduce a formidable ability to bring savings into what it aspires for in the most beautiful way: stability and security.
 
Balance Ethical Values is translated to English from French equilibre, éthique, valeurs.

Also: Ethical parameters to enable transparancy and balance.


8. Saving is a part of us. It's one of our first subconscious needs; it's encrypted in our genes

Obj(Θ)=L(θ)+Ω(Θ) Objective Function containing training loss and regularization.

Usually we will use θ to denote the parameters
Note difference between  lowercase θ and capital
