From fed625c80bb74d3cbbb9ec629c524f937f8a8267 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Sun, 22 Mar 2026 16:02:43 +0100 Subject: [PATCH] =?UTF-8?q?fix:=20last=202=20H100=20test=20failures=20?= =?UTF-8?q?=E2=80=94=20epsilon=20floor=20+=20min=5Fepochs=20override?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit dqn-smoke: epsilon=0.1 guarantees ≥2 distinct actions in 200 samples. Pure NoisyNet (epsilon=0) is non-deterministic — with small networks and random init, all 200 actions can be the same argmax. dqn-early-stop: override min_epochs_before_stopping=1 after smoketest profile (which sets 5). The test expects collapse at epoch 2 but min_epochs=5 prevents early stopping until epoch 5.
