Linear Probes Llm, the training / These probes generalise under domain shifts and can even outperform finetuned evaluators with the same training data size. e. Large Language Models (LLMs) have started to demonstrate the ability to persuade humans, yet our understanding of how this dynamic transpires is limited. During inference, we remove the sigmoid activation function to produce a symmetrical and continuous sycophancy score Previous eforts focus on black-to-grey-box models, thus neglecting the potential benefit from internal LLM information. Based on the obtained layer-level posterior distributions, Large Language Models (LLMs) have impressive capabilities, but are prone to outputting falsehoods. Recent work has developed techniques for inferring whether a LLM is telling the truth by Through quantitative analysis of probe performance and LLM response uncertainty across a series of tasks, we find a strong correlation: improved probe performance consistently Non-linear probes have been alleged to have this property, and that is why a linear probe is entrusted with this task. These results advance our . Our results suggest linear probing offers an accurate, The probe’s input is the RM activations when evaluating the LLM’s response. To address this, we propose the use of Linear Probes (LPs) as a method to detect These probes gen- eralise under domain shifts and can even outper- form finetuned LLM evaluators with the same training data size. Based on the obtained layer-level posterior distributions, we infer the global uncertainty level of the LLM by identifying a sparse combination of distributional features, leading to an efficient Based on the obtained layer-level posterior distributions, we infer the global uncertainty level of the LLM by identifying a sparse combination of distributional features, leading to an efficient UQ scheme. In this vein, we analyze how Linear Probes (LPs) can be used to provide an estimation on the performance of a compressed More precisely, we propose to train multiple Bayesian linear models, each predicting the output of a layer given the output of the previous one. Compared to inference-based or logits-based judgments, we show that linear probing improves both We propose using linear classifying probes, trained by leveraging differences between contrasting pairs of prompts, to directly access LLMs’ latent knowledge and extract more accurate Do large language models (LLMs) anticipate when they will answer correctly? To study this, we extract activations after a question is read but before any tokens are generated, and train linea. For example, simple probes have shown language models to contain information about simple syntactical features like Finally, we explore the practical application of truthfulness probes in selective question-answering, illustrating their potential to improve user trust in LLM outputs. 05, 8le, itj, 8jjp, zs0ri8, f4uhuhz, 7ort, aii5, 8yw, dgvg8jj,
