# CAPTIONBERT FULL BENCHMARK -- teachers, MiniLM, both trunks, arms
|
| 3 |
+
#
|
| 4 |
+
# One harness, one pass, every model measured on the SAME eight tasks with the
|
| 5 |
+
# SAME pooling and normalization. The card tables so far mixed sources: the
|
| 6 |
+
# teacher numbers came from a 2-task run, the trunk numbers from an 8-task run,
|
| 7 |
+
# and MiniLM was quoted for scale from a different pass. That is not a fair
|
| 8 |
+
# comparison and it is not defensible in a writeup.
|
| 9 |
+
#
|
| 10 |
+
# WHAT IS MEASURED
|
| 11 |
+
# 5 teachers bert-base, ModernBERT-base, roberta-base, albert-base-v2,
|
| 12 |
+
# distilbert -- the exact models the consensus was built from
|
| 13 |
+
# reference all-MiniLM-L6-v2 (contrastive, 1B+ curated pairs: a
|
| 14 |
+
# DIFFERENT comparison class, labelled as such)
|
| 15 |
+
# 2 trunks captionbert-8192-v2 (54 chunks) and -b (66 chunks)
|
| 16 |
+
# 2 arm sets each trunk with ITS OWN native arms -- anchors are
|
| 17 |
+
# trunk-bound (v2 arms on -b cost 31% of their gain)
|
| 18 |
+
#
|
| 19 |
+
# 8 TASKS: STS-B, SICK-R, STS12-16, BIOSSES. BIOSSES is 100 rows and is the only
|
| 20 |
+
# genuinely out-of-domain gauge; it is reported but never used alone.
|
| 21 |
+
#
|
| 22 |
+
# EVERY MODEL IS MEAN-POOLED AND L2-NORMALIZED. That is the honest setting for
|
| 23 |
+
# an untuned encoder and it is what the teachers were consensus-averaged in.
|
| 24 |
+
# It is also why bert-base scores low here: raw mean-pooled BERT is a known-weak
|
| 25 |
+
# sentence encoder, which is the entire reason Sentence-BERT exists. Beating it
|
| 26 |
+
# is a real efficiency result, not a competitive sentence-embedding result --
|
| 27 |
+
# the card should say so and the MiniLM row is there to keep that honest.
|
| 28 |
+
#
|
| 29 |
+
# Config at the top, functionality in the body, run logic at the base.
|
