            How does a gradient backpropagates through random samples?

            I'm learning about policy gradients and I'm having hard time understanding how does the gradient passes through a random operation. From here: It is not possible to directly backpropagate through random samples. However, there are two main methods for creating surrogate functions that can be backpropagated through.

            They have an example of the score function:

            It is indeed true that sampling is not a differentiable operation per se. However, there exist two (broad) ways to mitigate this - [1] The REINFORCE way and [2] The reparameterization way. Since your example is related to [1], I will stick my answer to REINFORCE.

            What REINFORCE does is it entirely gets rid of sampling operation in the computation graph. However, the sampling operation remains outside the graph. So, your statement

            isn't correct. It does not pass through any random operation. Let's see your example

            If I'm understanding correctly, you don't need/want to use the non-specialized role in the final module (that is, you aren't using the Series defined in Dan.rakumod in spike.raku – you're only using the specialized Series defined in Pandas.rakumod). Is that correct?

            If so, the solution is simple: just don't export the Series from Dan.rakumod – it's still our scoped (the default for roles) so you can still use it in Pandas.rakumod exactly the way you currently do (Dan::Series). But, since it's not exported, you it won't create a name clash with the non-prefixed Series.

            Normal distribution `N(mu, 1)>1.96`
            Asked 2022-Feb-28 at 20:24

            I try to write an R code to find value of mu s.t. the Normal distribution satisfies the probability P(N(mu, 1)>1.96)=0.95 (i.e., P(Z>1.96)=0.95 where Z~N(mu, 1) and mu is what I want to get). Is there any code for solving the parameter of distribution? It seems that this will be a integral equation about mu such that

            int_{1.96}^{\infty} 1/\sqrt{2\pi} \exp(-(x-mu)^2/2)dx=0.95

            We can sample Normal distribution from dnorm(x, mean, sd) or rnorm(n, mean, sd). But we need to first take value for mean and sd.

            Use uniroot to find the point where the probability equals 0.95. The function f is a way of writing this. The interval's end point are arbitrary, chosen because I wasn't not expecting the solution to be much faraway from the origin.

            As per the comments your code attempts to read and write to a map simultaneously and, as per the go 1.6 release notes:

            if one goroutine is writing to a map, no other goroutine should be reading or writing the map concurrently

            Looking at your code there appears to be no need for this. You can create the channels in advance; after they are created you are only reading from the map so there is no issue:

            Implementation of the Metropolis-Hasting algorithm for solving gaussian integrals
            Asked 2022-Feb-02 at 20:28

            I am currently having issue with the implementation of the Metropolis-Hastings algorithm.

            I am trying to use the algorithm to calculate integrals of the form

            In using this algorithm, we can obtain a long chain of configurations ( in this case, each configuration is just a single numbers) such that in the tail-end of the chain the probability of having a particular configuration follows (or rather tends to) a gaussian distribution.

            My code seems to be messing up with obtaining the said gaussian distributions. There is a strange dependence on the transition probablity (the probablity of picking a new candidate configuration depending on the previous configuration in the chain). However, if this transition probability is symmetric, there should be no dependence on this function at all (it only affects speed at which phase space [space of potential configurations] is explored and how quickly the chain converges to the desired distribution)!

            In my case I am using a normal distribution transition function (which satisfies the need to be symmetric), with width d. For each d I use I do indeed get a gaussian distribution however the standard deviation, sigma, depends on my choice of d. The resulting gaussian should have a sigma of roughly 0.701 but I find that the value I actually get depends on the parameter d, when it shouldn't.

            I am not sure where the error in this code is, any help would be greatly appreciated!

            ANSWER

            Answered 2022-Jan-16 at 23:56

            Attribute composition is not the time when attributes are added to the class; rather, it is the time at which:

            • We commits to a particular set of attributes for the class, and communicate this to the underlying runtime (usually MoarVM), which calculates a memory layout for the object
            • we tell each Attribute object to compose itself, which is its trigger to generate accessors, handles-related methods, and so forth

            I'm not clear on what you are intend to achieve, in so far as attributes are externally readonly by default anyway, and so it'd make more sense perhaps to produce an error if somebody defines an rw one on something declared frozen. If you do want to modify attributes, you'd probably have more luck overriding add_attribute and tweaking the way the attribute works at that point (for example, something like method add_attribute($obj, $attr) { callwith($obj, $attr.clone(:!rw, :!has_accessor)) } may achieve what you want).

            ANSWER

            Answered 2022-Jan-16 at 16:02

            There's a few misunderstandings in this attempt.

            1. There is one instance of a meta-class per type. Thus if we want to allow a given type to only be instantiated once, the correct scoping is an attribute in the meta-class, not a my. A my would mean there's one global object no matter which type we create.
            2. The compose method, when subclassing ClassHOW, should always call back up to the base compose method (which can be done using callsame). Otherwise, the class will not be composed.
            3. The method_table method returns the table of methods for this exact type. However, most classes won't have a new method. Rather, they will inherit the default one. If we wrap that, however, we'd be having a very global effect.

            While new is relatively common to override to change the interface to construction, the bless method - which new calls after doing any mapping work - is not something we'd expect language users to be overriding. So one way we could proceed is to just try installing a bless method that does the required logic. (We could also work with new, but really we'd need to check if there was one in this class, wrap it if so, and add a copy of the default one that we then wrap if not, which is a bit more effort.)

Below is my code currently and I am getting a "Solution not found" with "EXIT: Maximum Number of Iterations Exceeded". The simulation assumes a point mass with a non-rotating earth frame. The EOMS are 6 coupled, non-linear ODEs.
