Sai Swagat Mishra, Suchita Patel, P. K. Sahoo
We present, to our knowledge, the first systematic study of early-late cosmic evolution and acceleration in the framework of gravity, an extension of teleparal…
Can Small Language Models Use What They Retrieve? An Empirical Study of Retrieval Utilization Across Model Scale
Sanchit Pandey
Retrieval augmented generation RAG is widely deployed to improve factual accuracy in language models yet it remains unclear whether smaller models of size 7B parameters or less can…
Accelerating Cosmological Model with Scalar Field in Gravity
Y. Kalpana Devi, Rahul Bhagat, B. Mishra
In this work, we investigate the cosmological dynamics of gravity using two complementary scenarios: without a scalar field and with a minimally coupled genera…
