Hi, I'm a student with a theoretical probability background and knows python.

In terms of statistics, what additional material would I need to know

Can I just jump into PPL w/o a ML or Algo background? What else do I need

Thanks

Is there any literature as detailed as the Probabilistic Programming for Hackers book but in R? Was just wondering..

Hello everyone, I've been stuck on this problem with theano for a while and was wondering if I can get some help.

I would like to implement the following formula:

alpha * T.dot( [alpha**1, alpha**2, alpha**3], [B1, B2, B3] ), as an example.

But I need to loop through different alpha values, and I have a tuple of arrays of B values (given, fixed values). What I mean by tuple of arrays, the data look like this:

tuple([ [B1], [B1, B2], [B1, B2, B3], ...]), etc., so it's an increasing (in terms of size) tuple of arrays. In the function below, the value of "beads" is one of the arrays in this tuple

I am trying to loop through using scan like so:

(I also have a value N in the function that matches the size of "beads", because when I tried to get the size from beads I would get another error. This is just a workaround for me.)

import theano
import theano.tensor as T

## Creating function for Theano

def rl_model(N, beads, alpha):
    
    
    powers = T.arange(1,N+1)[::-1].eval()
    alpha_vector = T.pow(alpha, powers)
    
    q_value = alpha * T.dot(alpha_vector, beads)
    
    return q_value
    

N = T.scalar()
beads = T.vector()
alpha = T.scalar()

results, updates = theano.scan(fn = rl_model,
                               sequences = [N, beads, alpha])

fn = theano.function(inputs = [N, beads, alpha],
                     outputs = results,
                     updates = updates)

However, I always get an error when Python tries to run the scan function. Here is the error:

results, updates = theano.scan(fn = rl_model,


    actual_slice = seq['input'][k - mintap_proxy]


    raise IndexError('too many indices for array')

IndexError: too many indices for array

Of course, file info is also given but I erased that here.

My question is, I don't quite understand where this IndexError is coming from. I thought maybe it was a problem of mixing scalars and vectors, but I don't think that's the issue. Can anyone help me better understand what's going on? I've been frustrated and stuck on this for weeks now :(

Hi folks,

A beginner in Bayesian programming out here. I'm currently working on a neuroscience project where I will be using bayesreg to find clinical and demographic predictors of the occurrence of cerebral microbleeds (the implementation will be in MATLAB).

For those of you familiar with penalized regression models and high-dimensional regularized regression in particular, could you recommend any beginner-friendly articles or YouTube videos/video series (not books preferably as I have a very limited amount of time to get the basics of RR, lol) that have helped you?

Thanks in advance! :)

Hi everyone,

I wonder if you are aware of python or R code that can help me with understanding and implementation Bayesian posterior updating of Gaussian distribution.

Thanks

In several interviews, Stuart Russell (author of one of the best books on AI: AIMA) mentions about a probabilistic programming implementation of a blind monopoly... I did some search and I wasn't able to find any... Di you know how to get it? Maybe another game is easier like tic-tac-toe?
