Work #2 introduces a latent-variable approach for bivariate causal discovery. A generative method estimates the functional causal model equation, proving effective on benchmark datasets. 🧠 #LatentVariables #CausalInference 📜iopscience.iop.org/article/10.108…

Since the difference between log-likelihood and the auxiliary function is a #KLDiverence, the #EM algorithm can be viewed as an iterative process to minimize this difference and find our 'best guess' to the values of the #latentVariables given the data. #readingOfTheDay
Based on #JensensInequality, the #EM algorithm finds an auxiliary function so that the log-likelihood is an upper bound for this function in E-step and then maximizes the auxiliary function (equivalent to maximize the log-likelihood) wrt the parameters in M-step.#readingOfTheDay
2/ VAEs are a type of generative model that learns to represent the input data in a compressed form called the "latent space." #generativemodels #latentvariables
5/ Next step: Factor Analysis using that matrix factormat R, n(# of observations) mineigen(1) This extracts factors from your tetrachoric matrix using eigenvalue decomposition. #LatentVariables #StataCoding
Some of my favorite tool of interest being used in this work! 😃😉 Cool work & enjoyed the quick read of the strategy & findings. 👌 #Bioinformatics #Genomics #latentvariables #Statistics #RareDisease
I’m super excited to announce our latest work to #endNF written by @jinetab and @allawayr. biorxiv.org/content/10.110… It introduces a lot of fun ways to explore #bigdata in #raredisease, where sample sizes are scarce. (1/n)
Y’all that midterm was rough #phdlife #latentvariables #SEM #stats
Ahhh.... gotcha. Let me introduce you to a potential ally in your quest @imcommon #latentvariables
A #HiddenMarkovModel is a 'dynamical' mixture model, a linked sequence of the #latentVariables, or '#states', such that the choice of a state at t step depends on that at t-1 step and the observed outputs are independent given the state. cs.cmu.edu/~lebanon/pub/b… #readingOfTheDay
When the parent Z of X_i (i=1,2,3) is unobserved #latentVariable, X_i and the estimates of the parameters are no longer independent. We use #ExpectationMaximizationAlgorithm to solve maximum likelihood problem involving a #latentVariable. cs.cmu.edu/~lebanon/pub/b… #readingOfTheDay
#EM is an iterative optimization and is coordinate ascent/hill-climbing on a likelihood function by averaging over (#expectation) the #latentVariables to bypass the unobserved uncertainty. Then we #maximize it to explore potential ascent. cs.cmu.edu/~lebanon/pub/b… #readingOfTheDay

Every time someone mentions a ‘latent variable’ I imagine some big scary unknown hiding just around the corner, about to jump out and change my scientific hypothesis. #compbioproblems #latentvariables #anthropomorphizingmath
First, @allawayr used data from nfdataportal.org , a collection of diverse tumors across NF and leveraged MultiPLIER to assess #latentvariables modeled across _other_ transcriptomic datasets. cell.com/cell-systems/p… with help from @jacklyn_taroni and @GreeneScientist (2/n)
