    Python Building a homemade Long Short Term Memory with FSMs

    I shall now elaborate on how the network of FSMs work. Allow the system to contain N FSMs for a large value N say ##10^4##. Each FSM has it's output assigned to a random weight and multiplied by it. Hence the aggregate output of the system gives $$\sum_{i=1}^N w_i o_i= \textbf{w}^T\textbf{o}_t$$...

    Python Building a homemade Long Short Term Memory with FSMs

    I am doing a project to build a Long Short Term Memory algorithm from scratch. LSTMs are capable of retaining memory of the past inputs and carrying them for future operations thanks to Recurring Neural Networks to process a series of inputs such as sounds and text. One possible way I can think...

    I Is there any mechanism possible for the Big Brake?

    Yes the Scientific American article does in fact make a lot of unverifiable claims like the big lurch in the picture which has no supporting reference as well as the claim that phantom energy freezes everything in place.

    I Is there any mechanism possible for the Big Brake?

    https://arxiv.org/abs/0705.1688 https://ui.adsabs.harvard.edu/abs/2014IJMPD..2350054P/abstract https://www.scientificamerican.com/article/time-s-end-will-be-the-end-of-endings/ According to these references they suggest that dark energy can suddenly change sign and causing the universe expansion...

    What is a proper quality post

    You mean that one flaming the mentors and calling them 'Einstein worshippers ' for that warning on personal theory? Nope that wasn't me or I'll be perm banned. I also want to see who made that post.

    What is a proper quality post

    Assertions means not facts that the general science community agrees with rite? Because honestly I do not need a reference if I bring up F=ma of E=mc^2 etc.

    What is a proper quality post

    I currently have a warning for poor quality posts or what mods call 'substandard' posts. I'm not trying to argue with the mods or appeal anything here in the post.But rather I wish to know what kind of posts the mods accept. I understand the need for PF to be heavily moderated to keep crackpots...

    How do mods combat pseudoscientific misunderstandings among users

    There are some offences that carries an immediate permenant ban on this forum but for those who brings up conspiracy theories I think we should try to correct them first before taking action against them

    How do mods combat pseudoscientific misunderstandings among users

    But what happens that the user gives a link to a non credible source but doesn't know that it's questionable, will users get banned or infractions for giving links to questionable sources if they do not know about the credibility of the source

    I Finding the pdf of a transformed univariate random variable

    Apologies the website gave gives the formula for the general normal distribution for the standard normal, take ##\sigma=1,\mu=0## in the equation

    I Finding the pdf of a transformed univariate random variable

    Suppose ##Y=f(X)## and we know the pdf of X. To get the pdf of Y, we can find the CDF of Y ##P(Y<y)## then differentiate it wrt to y to get the pdf. $$P(Y<y)=P(f(X)<y)$$ And depending on X you have to do an appropriate manipulation to get the cdf of Y. Here's and example, deriving the pdf of a...

    How do mods combat pseudoscientific misunderstandings among users

    The internet is full of nonsensical ideas and conspiracy theories which is why sometimes those nonsense ends up on PF. Let's be fair some trolls post pseudoscience on PF intentionally while there are many who post them here unintentionally, like me five years ago. So according to the rules...

    I Vector visualization of multicollinearity

    General linear model is $$y=a_0+\sum_{i=1}^{i=k} a_i x_i$$ In regression analysis one always collects n observations of y at different inputs of ##x_i##s. n>>k or there will be many problems. For each regressor, and response y ,we tabulate all observations in a vector ##\textbf{x}_i## and...

    I How can I test for positive semi-definiteness in matrices?

    On a side note I'm posting on PF more frequently as I have exams coming and I need some help to understand some concepts. After my exams I will probably go inactive for a while. So I'll get to the point. Suppose we have a matrix A and I wish to check if it is positive semi definite. So one easy...
