Coronal emission lines as thermometers
Coronal emission line intensities are commonly used to measure electron
temperatures using emission measure and/or line ratio methods. In the presence
of systematic errors in atomic excitation calculations and data noise, the
information on underlying temperature distributions is fundamentally limited.
Increasing the number of emission lines used does not necessarily improve the
ability to discriminate between different kinds of temperature distributions.Comment: Accepted by ApJ, November 200
Trapping LLM Hallucinations Using Tagged Context Prompts
Recent advances in large language models (LLMs), such as ChatGPT, have led to
highly sophisticated conversation agents. However, these models suffer from
"hallucinations," where the model generates false or fabricated information.
Addressing this challenge is crucial, particularly with AI-driven platforms
being adopted across various sectors. In this paper, we propose a novel method
to recognize and flag instances when LLMs perform outside their domain
knowledge, and ensuring users receive accurate information.
We find that the use of context combined with embedded tags can successfully
combat hallucinations within generative language models. To do this, we
baseline hallucination frequency in no-context prompt-response pairs using
generated URLs as easily-tested indicators of fabricated data. We observed a
significant reduction in overall hallucination when context was supplied along
with question prompts for tested generative engines. Lastly, we evaluated how
placing tags within contexts impacted model responses and were able to
eliminate hallucinations in responses with 98.88% effectiveness.Comment: 13 pages, 3 Figures, 2 Table
