Randomness of Low-Layer Parameters Determines Confusing Samples in Terms of Interaction Representations of a DNN

Junpeng Zhang, Lei Cheng, Qing Li +2

In this paper, we find that the complexity of interactions encoded by a deep neural network (DNN) can explain its generalization power. We also discover that the confusing samples…

Quantifying In-Context Reasoning Effects and Memorization Effects in LLMs

Siyu Lou, Yuntian Chen, Xiaodan Liang +2

In this study, we propose an axiomatic system to define and quantify the precise memorization and in-context reasoning effects used by the large language model (LLM) for language g…
