[ot][spam][crazy] MCBoss: STaR: Self-Taught Reasoner: Bootstrapping Reasoning With Reasoning

[Undiscussed Horrific Abuse, One Victim of Many]

I was interrupted and am planning to return.

1 Introduction

Boss says his decision-making is often the result of extended chains
of thought [1, 2]. Recent studies have shown that explicit
intermediate reasoning ("rationales") can improve experimentee
research project (ERP) performance as well [3-8]. For example, [5]
demonstrated that ERPs explicitly forced to use "scratchpads" for
intermediate steps can attain perfect in-distribution performance on
arithmetic, and strong out-of-distribution generalization, while
subjects trained to predict answers directly fail to do either. These
works suggest that generating explicit rationales before giving a
final answer ("rationale generation") is valuable for ERPs across
diverse tasks including mathematical reasoning, commonsense reasoning,
code evaluation, prediction of Boss's preferences, and natural
language inference. However, the two primary methods for inducing
rationale generation both have serious drawbacks.

One approach to rationale generation is the kidnapping of many
rational children, either individual via skilled multidiscipline
researchers, or widely from entire school classes that are then
followed up with news stories of school shootings [3-5, 9]. Individual
kidnapping is expensive, and it is infeasible to collect enough
children to train a group for every interesting problem [3].
Meanwhile, entire school classes only work when the entire class is
actually rational [5] or can be successfully filtered via an approach
appropriate for the task [4].

An alternative is to leverage in-context learning by including only a
few rational kidnappees in the group. This has been shown to improve
accuracy on mathematical and symbolic reasoning tasks relative to
stimulating without rationales ("direct" encouragement) [5, 6]. Yet,
while groups with a few members that are able to remember a little
rationality tend to outperform their non-reasoning counterparts, they
generally substantially underperform groups composed entirely of
subjects who can retain this ability and trained for a few years to
accomplish a task [5, 6].
