Inference-Time Intervention:推理时间干预 Autoregressive 自回归:自回归模型(AR模型)是一种处理时间序列的统计方法,它利用同一变量之前各期的表现情况,来预测该变量本期的表现情况,并假设它们之间存在线性关系 本文主要介绍了一种名为"Inference-Time Intervention (ITI)"的技术,目的是提高大型语言模型的真实性。该技术...
读论文Inference-Time Intervention 完整标题:Inference-Time Intervention: Eliciting Truthful Answers from a Language Model 出处:NIPS‘23 哈佛大学 这篇文章阐明了中间层信息和输出层信息之间可能存在差距,即LLM再从中间层过渡到输出层时激活空间中的方向偏离了真实方向。因此,作者提出了一种干预方法,根据激活空间中向...
We propose Inference-Time Intervention (ITI): shifting the activations along the difference of the two distribution means during inference time; model weights are kept intact.The same intervention process is repeated for generation of each token autoregressively. Here’s an example. For the same ...
Zen provided this really cool library called pyvene that can be used to load Inference-time Intervention, and many other mechanistic intervention technique. Here is what he says:pyvene pushes for streamlining the sharing process of inference-time interventions and many more, comparing with other ...

Estimating the effect of an intervention and identifying the causal relations from the data can be performed via causal inference. Existing surveys on time series discuss traditional tasks such as classification and forecasting or explain the details of the approaches proposed to solve a specific task...
Rationale, aims, and objectives Interrupted time-series analysis (ITSA) is a popular evaluation methodology in which a single treatment unit's outcome is studied over time and the intervention is expected to "interrupt" the level and/or trend of the outcome, subsequent to its introduction. When...
However, if any critical deterioration is detected, then the decision of when to take the intervention, given the costs of diagnosis and therapeutics, is of fundamental importance. In this paper, Bayesian inference of a nonhomogeneous Poisson process with power law failure intensity function is ...
