Hybrid Hard–Soft Clustering For Outlier Detection: Development of the HS-COS Framework

Ruchi Trivedi, Namita Srivastava

Outlier detection is essential for maintaining the robustness of data-driven models in fields such as healthcare and ecommerce. However, existing clustering-based techniques, such as K-Means, Fuzzy C-Means (FCM), and Possibilistic C-Means (PCM), only capture an aspect of anomaly behavior, such as…

Calibration Estimation in Stratified Random Sampling Using Three Constraints

Namita Srivastava, Ruchi Shakya

Calibration estimation improves the precision of population parameter estimates by incorporating specified auxiliary information. In this article, we have proposed a new calibration estimator for estimating the population mean in stratified sampling, based on three new calibration constraints…

The Universal Topological-Energy Law of Evolution and Dynamic Stability of Systems (Ovchinnikov's Law)

Ovchinnikov S.V.

This work presents a universal law governing system evolution through the dimensionless parameter . The law unifies quantum, classical, and relativistic phenomena, including - critical points (quantum coherence), (bifurcation), (topological collapse). Experimental proof -Nichrome wire rupture (…
