Visualization of multiple Markov models

I am working on a project where we compare over 10 different Markov models, each representing a different treatment plan. Most often single models are visualized with a decision tree or transition state diagram. However, with multiple different…

Modeling uncertainty from Logistic Regression

Logistic regression is a part in a simulation pipeline that I use for some scenario analysis. The dataset that this is based on is not small but relatively noisy, and only one explanatory variable/feature. Of course I can say something about this…

Estimating the value of $\pi$ with a Monte Carlo dartboard: $<$ or $\leq$?

I'm trying to figure out which is the proper way to estimate $\pi$ using the Monte Carlo method randomly distributing points in a square that also contains an inscribed circle. Some sources say to use the comparison of $\sqrt{x^2+y^2}\le 1$, while…

Using simulations to train ML algorithms

Possibly similar question: Is it ok to collect data using algorithm to train another? I have a model that accurately describes an underlying physical, complex, system. The model is basically a set of ODEs based on the physics of the system,…

What visualization I should choose for Monte Carlo simulations in timeline events?

I wasn't sure if I should open this question in Cross Validated or here. But since the question belongs to a bigger project related with Data Science, I chose this one. I will present a simplified version of my working project, since the original is…

Finding similarity between two datasets

I have two datasets. One is actual percentage of white population in counties in an american state and the other is the simulated percentage of white population in counties in an american state. Bits about my simulation: It is a random simulation…

Similarity Measure of Simulated Time Series vs Observed time Series

In my work I have an observed Time Series and Simulated ones. I want to compare the Light Curves and check for similarityto find out which simulated curve fits best respectivley which parameters simulate the Light Curve the best. At the moment I do…

Ways to simulate weather data over several periods (Python or R)?

I have a time series dataset that has several variables for a state/province for fixed periods of time. That is for state A, there are samples from April 2017 to July 2019. Of course, I thought adding precipitation and temperature variables would be…

How to simulate customer walk-ins for a given period in a fast food chain in R

I would really appreciate it if someone could tell me where I would start in tackling the following tasks in R. I'm not a data-science expert and am trying to teach myself data-analysis from a background in physics. I have introductory statistics…

Testing Multi-Arm Bandits on Historical Data

Suppose I want to test a multi-arm bandit algorithm in the contextual setting on a set of historical data. For simplicity, let's assume there are only two arms A and B and suppose the rewards are binary. Furthermore, suppose I have a data set where…

Building a simulator for continuous state, discrete action reinforcement learning

I am trying to build a simulator that optimizes the performance and temperature of a device. I want the device to perform well, but without making the device too hot. If the device becomes too hot, I want the internal circuitry to push down the…
