Single-index logistic model for high-dimensional group testing data
Group testing is an efficient screening method that reduces the number of tests by pooling multiple samples, making it especially effective in low-prevalence settings. This strategy gained significant attention during the COVID-19 pandemic, and has since

Spectrum adapted expectation-maximization algorithm for high-throughput peak shift analysis
We introduce a spectrum-adapted expectation-maximization (EM) algorithm for high-throughput analysis of a large number of spectral datasets by considering the weight of the intensity corresponding to the measurement energy steps.

An Integrated Approach for Making Inference on the Number of Clusters in a Mixture Model
This paper presents an integrated approach for the estimation of the parameters of a mixture model in the context of data clustering. The method is designed to estimate the unknown number of clusters from observed data.

Achieving the oracle property of OEM with nonconvex penalties
Thepenalised least square estimator of non-convex penalties such as the smoothly clipped absolute deviation (SCAD) and the minimax concave penalty (MCP) is highly nonlinear and has many local optima.

Maximum Likelihood Estimation for an SAG Mill Model Utilizing Physical Available Measurements
In this paper, we have proposed a new paradigm for modeling of SAG mills. Typically, important parameters found in the modeling of such processes are described as state-space system model rather than unknown parameters.
