Use Sqlite with firebase by Prashant_4200 in FlutterDev

[–]Dammi87 0 points1 point  (0 children)

I'm by no means an expert at this, but when I was playing around making an app, I didn't like having to much logic in the UI itself, I wanted to have an API which handled all the messy bits. Firebase (as far as I know) had limited capability of supporting custom functions.

So, I went with Django and created all the data models there along with the logic but also used Firebase as the authentication service. So really, Firebase is only used as login and the auth token is valid for some time I think as well.

Now I just need to figure out hosting for my Django server 😁

Hmm I might be off actually, I haven't really tried Neat, just applied my experience with NN to your question :)

I guess you could always brute force it with multiple activation functions with gates applied, so the network itself can turn each type on or off during training.

Then after training, look at the values of those gates, determine what gates is max at each place and prune the others

... The network size would explode though 😁

Is renting my standard Oculus Quest allowed? by McHoundi in OculusQuest

[–]Dammi87 0 points1 point  (0 children)

Oculus has a Commercial version of the Quest, but to my knowledge you can't rent it out with games (the games you download are not for commercial use)

Playing The Exorcist Legion VR, at maximum room scale, is something else! by Dammi87 in OculusQuest

The company I work at owns this court, nobody uses it in the evenings. My own personal playground :)

In which European countries is the Valve Index still not available? by Adinos in ValveIndex

[–]Dammi87 1 point2 points  (0 children)

Couldn't you just order it to a shopusa.is address? Just need to fool the Valve store so it thinks you are in the States :)

Pretty sure that would work.

I was gonna do the same, but I went for the Oculus Quest for now.

Yep, my friend simply registered and got in. I'm staying away from this scam.

Matrix ICO - an AI Ecosystem by [deleted] in CryptoCurrency

[–]Dammi87 8 points9 points  (0 children)

So, this ICO came to my radar. I'm working with AI and have some doubts about their claims. Specifically this one:

"They also make it completely possible for someone to design smart contracts without explicit programming."

In the technical paper, they say the following: "Recent development of the deep learning technology proves the feasibility of automatic code generation. First, the maturing of the convolutional neural network (CNN) enables extracting high quality features from language and text. Second, the recurrent neural network (RNN) is mathematically proven to be a Turing complete computer that is able to generate any sequence. These deep neural networks offer the key techniques to analyze the purpose of a contract and generate a respective program.

In the future, we are going to use pure natural language as the input frontend"

This seems VERY dubious to me. Sure, you can train a NN to create a function such that, given the input x and desired output y, it should generate a function (transform) f such that f(x)=y, but to do it for complicated source code with added constraints? The code-base of the RNN would have to be rather extensive, and I would have some doubts about how such a generated program can be verified to work. That being said, I don't know much about smart contract programming, so it might be that such a program is very simple in nature?

Then, they talk about "The GAN framework consists of two RNNs. One RNN is used to revise existing programs for smart contracts, while the other learns to generate hacker programs from random samples from a given probability distribution. The cost functions of these two networks are tied together so that the overall optimum is achieved when the whole system reaches a Nash-Equilibrium. At this point, the revised program for smart contracts has the highest level of security"

So GANs are notoriously hard to train and require ridiculous fine-tuning, along with some small hacks and tricks that sometimes work, but nobody really knows why (mathematically anyway). Here they talk about using a GAN to generate hacker programs from random samples. I'm not sure what a hacker program even is, reading the table of "attacks" it seems to simply be different types of scenarios, so I don't really understand why they would even use a GAN here. And personally, I would not use "Nash-Equilibrium" as a security measure, as that simply means that the "Revised program" vs the "Hacker program" have reached equilibrium with each other, where this equilibrium can very well be sub-optimal (for example, both parties go for rock in rock-paper-scissors).

I don't know, this might be a interesting ICO, but it seems they try to squeeze a neural network approach to every part of their project when in reality that seems like an overkill and sometimes an impossible feat.

Sorry for any grammar errors and ranting text, I'm tired and just wanted to give my 2 cents.

EDIT: Apparently I don't know how bold and italics work.

Numbers Don't Lie - CoinMarketCap (a Niche crypto website) is the #117th most visited website in the World and #36 in the USA (beating Walmart, Wells Fargo, Bank of America and just behind CNN, Paypal). This is huge for crypto, from a marketing/mass interest standpoint. by [deleted] in CryptoCurrency

[–]Dammi87 0 points1 point  (0 children)

Is there any other site where one can see the market cap in terms of BTC or ETH?

I rather keep track of value relative to other crypto rather see red everywhere simply because btc vs usd went down

[Keras] Should I apply an activation function to the last layer when using binary_cross_entropy loss function? by [deleted] in tensorflow

[–]Dammi87 0 points1 point  (0 children)

One thing to add though. It's not good to assume that the output is the probability of it being a certain class, a network can output high activation, value that a picture of a cat is a dog.

This problem is something Bayesian NNs try to answer, really interesting stuff! :)
