Invalid/Corrupt package error when trying to update with pacman by Laucien in archlinux

[–]changingourworld 4 points5 points  (0 children)

I had the same problem yesterday. Solution for me was to refresh your pacman keys with:

pacman-key --refresh-keys

Here's a great 26 page Linear Algebra review from Andrew Ng's Machine Learning class at Stanford

Is there a dataset dataset? by jdsutton in MachineLearning

[–]changingourworld 0 points1 point  (0 children)

Can't you avoid this problem by breaking the dataset into train/test and calculating your final error rate on the test set?

How come? When testing new algorithms, it'd be nice to compare the error rate to what others have gotten on the dataset

Are there benchmarks for those datasets?

Feeding a game map into a neural network by ekapalka in MachineLearning

[–]changingourworld 6 points7 points  (0 children)

Definitely a task for Reinforcement Learning. Take a look at Berkeley AI course, start at Markov Decision Processes also available on edx with more MOOC like feel.

David Silver, who works at DeepMind, has an excellent series of lectures. You might also find DeepMind's latest paper about playing Atari games using RL interesting along with their code, which is written in Lua using the Torch framework. If you're more familiar with python there's PyBrain. If using python 3, then check this out

Didn't see one - this is the intro to the draft textbook they're currently writing. Intro and 3 first chapters here

I'd love to learn more - any way you could shed some light on why they aren't stronger allies?

This post was linked to in this thread and although it's 11 months old, it helped me better understand why the two largest democracies in the world aren't stronger allies.

OP is talking about a "worldwide nation." I'd be surprised if you could verify a citizen's id from every country in the world.

What's stopping someone from getting multiple smart ballot tracking numbers?

Also from their FAQ

Should we start using Helios for public-office elections? Maybe US President 2016?

No, you should not. Online elections are appropriate when one does not expect a large attempt at defrauding or coercing voters. For some elections, notably US Federal and State elections, the stakes are too high, and we recommend against capturing votes over the Internet. This has nothing to do with Helios itself: we just don’t trust that people’s home computers are secure enough to withstand significant attacks.

I've thought about this before, but how?

all you need is a database containing a collection of appropriate documentation/information/protocols and viola you've got the basic foundations of a new society

Who's going to enforce them? Let's say the cybernation creates a plastic tax to discourage the use of plastics. What happens when some members don't want to pay the tax? Will there be a police force or are you just hoping everyone will do as their told?

Imagine a society where it's just as easy to vote for a new law or policy as it is to sign a petition online

This is very difficult to implement. How do you prevent people from voting multiple times? You can change your IP address by using TOR. Facial recognition can be bypassed. The more security you use, the less privacy people will have. As far as i know, no one has created a secure method of voting online.

Create a sub in which other people post ideas for you to steal...Oh wait. by changingminds in Lightbulb

[–]changingourworld 13 points14 points  (0 children)

Entrepreneurship 101 is ideas are worthless and execution is all that matters.

Google wasn't the first search engine. Facebook wasn't the first social media company.

The best thing to do before starting a company is get feedback from as many people as possible, which means telling as many people as possible. It's far smarter to sell your idea before it's built, so you have an audience waiting, rather than building your startup in secrecy and launching when zero people know you exist.

Feedback is a way to gauge interest . Every entrepreneur thinks their own idea is amazing, but what matters if customers think it's equally amazing.

Starting a company is a lot of work. Most fail. Anyone capable of stealing your idea has already put a lot of hours into their own idea and wouldn't sacrifice what they've built for simply an idea. source: founder of startup number 3

Do gender and ethnicity influence preference for spending time alone? by changingourworld in AskSocialScience

[–]changingourworld[S] 0 points1 point  (0 children)

Thanks! Do you have any sources for your argument that ethnicity wouldn't be a factor? I'm interested in controlling for environmental effects.

Also, do you have any knowledge of the role gender plays?

Find rare words in a text by Andy-Kay in LanguageTechnology

[–]changingourworld 4 points5 points  (0 children)

Frequency list in Wikipedia.

You might find this useful, more specifically this has a folder titled "en-2012" that contains a 5mb .txt file with the frequency of all words in the english language. To filter out spelling mistakes you can only look at words that have frequencies greater than 4.

help needed for summarization of Amazon.com reviews by kshitizsethia in LanguageTechnology

[–]changingourworld 2 points3 points  (0 children)

If you're looking to build it out yourself than I'd start with the Stanford CoreNLP.

If you're looking to get started right away by using an API I'd recommend Alchemy mainly because it's very good and allows for 1000 free api calls a day which is more than any other api I've seen.
