WebApr 13, 2024 · GPT models are OpenAI’s solution for several natural language processing tasks, including copywriting, parsing, classification, and summarization. ... This includes recognizing the potential harms that could come with incorporation of generative AI models into surgical practice. Because generated content is dependent on the data used during ... Most classification algorithms fall into one of two categories: discriminative and generative classifiers. Discriminative classifiers model the target variable, y, as a direct function of the predictor variables, x. For instance, logistic regression uses the following model, where 𝜷 is a length-D vector of coefficients and x … See more We’ll use the following conventions for this article. 1. Let v[i] be the ith entry in a vector v. 2. The target is the variable we are trying to model. The predictors are the variables we use to … See more A generative classifier models two sources of randomness. First, we assume that out of the 𝐾 possible classes, each observation belongs to class 𝑘 independently with probability given by the kth entry in the vector 𝝅. I.e., 𝝅[k] gives … See more Let’s start by deriving the estimates for 𝝅, the class priors. Let I_nk be an indicator which equals 1 if y_n = k and 0 otherwise. We want to find an expression for the likelihood of 𝝅 given the data. We can write the probability that … See more Now let’s get to estimating the model’s parameters. Recall that we calculate P(y = k x)with To calculate this probability, we need to first estimate 𝝅 (which tells us P(y = k)) and to second estimate the parameters in the distribution … See more
