eARCO: Efficient Automated Root Cause Analysis with Prompt Optimization
Drishti Goel, Raghav Magazine, Supriyo Ghosh +5
Root cause analysis (RCA) for incidents in large-scale cloud systems is a complex, knowledge-intensive task that often requires significant manual effort from on-call engineers (OC…
Understanding Physical Properties of Young M-dwarfs: NIR spectroscopic studies
Dhrimadri Khata, Soumen Mondal, Ramkrishna Das +2
We present here medium resolution (λ/Îλ\sim1200) H- and K-band spectra of M type dwarf stars covering the wavelength range 1.50 - 1.80 μm and 1.95 - 2.45 μm. The sample includ…
CARMO: Dynamic Criteria Generation for Context-Aware Reward Modelling
Taneesh Gupta, Shivam Shandilya, Xuchao Zhang +5
Reward modeling in large language models is susceptible to reward hacking, causing models to latch onto superficial features such as the tendency to generate lists or unnecessarily…
Exploring large language models for microstructure evolution in materials
Prathamesh Satpute, Saurabh Tiwari, Maneet Gupta +1
There is a significant potential for coding skills to transition fully to natural language in the future. In this context, large language models (LLMs) have shown impressive natura…
Use of solid fused silica etalon with broadband metallic coatings for calibration of high-resolution optical spectrograph
Supriyo Ghosh, William Martin, Kajal Kunverji +1
Wavelength calibration is a key factor for high-resolution spectroscopic measurements for precision radial velocities. Hollow-cathode lamps (e.g., ThAr), absorption cells (e.g., io…
Simulation of temperature, stress and microstructure fields during laser deposition of Ti-6Al-4V
Supriyo Ghosh, Kevin McReynolds, Jonathan E. Guyer +1
We study the evolution of prior columnar phase, interface phase, and phase during directional solidification of a Ti-6Al-4V melt pool. Finite element simulations esti…
