From 8edd4505568ef327eb72be2c5c57d24439b36986 Mon Sep 17 00:00:00 2001 From: YurenHao0426 Date: Wed, 8 Apr 2026 15:31:03 -0500 Subject: Intro: add slower FA-first opening paragraph (user feedback) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User flagged that intro entered the critique too fast without first explaining what feedback alignment is. Based on Bartunov et al. 2018's intro structure (their Section 1 opens with the weight-transport problem, introduces FA as the response, and only then motivates the evaluation question), rewrote §1 paragraph 1. New §1 ¶1: - BP is standard but biologically implausible (weight-transport problem) - FA (Lillicrap 2016) side-steps via random feedback - DFA (Nokland 2016) simplifies by direct projection per layer - Parallel lines: target propagation (Lee 2015), equilibrium propagation - Modern scaling: Launay 2020 (transformers), Akrout 2019 - Evaluation converged on accuracy + Gamma cosine summary §1 ¶2 (old ¶1) then starts the audit critique against this backdrop, so a reader who arrived without any FA context now has one paragraph of set-up before the critique begins. Page-budget side effect: the ~110-word addition pushed main content to 10 pages briefly. Recovered by shrinking Figure 4 (cross_arch_summary) from width=\linewidth to width=0.78\linewidth, which freed enough p9 vertical space for §7 to fit entirely on p9. Result: main content strictly 9 pages (§1-§7 on p1-p9, references and appendices on p10+). Total 18 pages. 0 overfull hbox.
