HybridRAG: A Practical LLM-based ChatBot Framework based on Pre-Generated Q&A over Raw Unstructured Documents
Sungmoon Kim, Hyuna Jeon, Dahye Kim +3
Retrieval-Augmented Generation (RAG) has emerged as a powerful approach for grounding Large Language Model (LLM)-based chatbot responses on external knowledge. However, existing RA…
Estimation of the rate parameter of the probability distribution on the regression setup
Jiwoong Kim
When the rate parameter of the exponential distribution is associated with predictors, then the main interest will be how to estimate the regression parameter. In this paper, we wi…
A Fast Algorithm for Implementation of Koul's Minimum Distance Estimators and Their Application to Image Segmentation
Jiwoong Kim
Minimum distance estimation methodology based on an empirical distribution function has been popular due to its desirable properties including robustness. Even though the statistic…
A Fast Algorithm for Solving Henderson's Mixed Model Equation
Jiwoong Kim
This article investigates a fast and stable method to solve Henderson's mixed model equation. The proposed algorithm is stable in that it avoids inverting a matrix of a large dimen…
Robust estimation of parameters in logistic regression via solving the Cramer-von Mises type L2 optimization problem
Jiwoong Kim
This paper proposes a novel method to estimate parameters in a logistic regression model. After obtaining the estimators, their asymptotic properties are rigorously investigated.
A new estimation for probability distributions using optimization
Jiwoong Kim
Many probability distributions belong to a location-scale family. One such an example is a normal distribution. Probability distributions of the family possess many desirable merit…
Generalized Minimum Distance Estimators in Linear Regression with Dependent Errors
Jiwoong Kim
This paper discusses minimum distance estimation method in the linear regression model with dependent errors which are strongly mixing. The regression parameters are estimated thro…
Robust and Efficient Estimation for Count Data Using L2 Optimization
Jiwoong Kim
This paper proposes a novel method to estimate the rate parameter of the Poisson distribution. The proposed method employs the Cramer-von Mises type optimization which has been com…
Specification Test based on Convolution-type Distribution Function Estimates for Non-linear Auto-regressive Processes
Kun Ho Kim, Jiwoong Kim
The paper proposes a specification test based on two estimates of distribution function. One is the traditional kernel distribution function estimate and the other is a newly propo…
A Goodness of Fit Test for Non-Gaussian Distributions with Unknown Location and Scale Parameters
Jiwoong Kim
This paper studies computational aspects of an asymptotically distribution-free goodness-of-fit test for non-Gaussian distributions based on the Khmaladze martingale transformation…
