Add fa_core_news_trf tier on a shared fine-tuned ParsBERT
Trains tagger, morphologizer, trainable_lemmatizer, parser and ner against one fine-tuned HooshvareLab/bert-base-parsbert-uncased through TransformerListener, rather than the sm/md/lg split where ner is trained separately and sourced in. Fine-tuning a 162M-parameter encoder twice would double GPU cost, ship two encoders in one wheel, and collide on the `transformer` component name. A shared encoder needs one corpus carrying both annotation layers, so merge_joint_corpus.py fuses them. corpus/perdt-ner/ came from the same --merge-subtokens CoNLL-U as corpus/merged/ with the same --n-sents, so the DocBins are token-for-token identical; the script asserts that per document and copies doc.ents by token index. Char offsets do not work here because the two converters differ in trailing whitespace, which pushes char_span off the token grid and returns None. Trained on a Colab T4 in 1h58m, 3000 steps, no early stop. Test scores against lg: DEP_LAS 90.79 (+4.19), ENTS_F 82.89 (+6.95, almost all recall), TAG_ACC 97.62 (+1.07). DEP_LAS passes the hazm+ParsBERT reference of 89.34, which no CPU tier reached. LEMMA_ACC 97.31 and SENTS_F 97.35 regress against lg; the likely cause of the latter is strided_spans leaving only 32 tokens of overlap. max_steps and learn_rate.total_steps are held equal on purpose. They are independent knobs, and a patience stop under a longer total_steps ends training at a high learning rate, discarding the annealing tail. finalize_pipeline.py now reads the encoder name out of the trained config instead of hardcoding it, tracks per-encoder licences, and writes a redistribution warning into meta.json when the encoder states none. ParsBERT states none, so that wheel is not redistributable; roberta-fa-zwnj-base (Apache-2.0) is a one-line change to `name`. Add benchmark_throughput.py, which times nlp.pipe alone. The words/s from `spacy benchmark accuracy` includes the Scorer's per-token alignment, which is why MODELS.md 7 reported ent_lg as faster than sm despite an identical ner architecture. Remeasured every tier on CPU and the 940MX; a background rsync halved every figure, so the final numbers are 9-run medians on an idle machine. Add make_model_card.py, which composes the Hub card from meta.json and the throughput records. The card spacy package writes has no frontmatter, so the Hub cannot index the model by language, and no install line or usage.

|
|
||||||
|
The `trf` tier is a different kind of thing: 187 words/s on the same laptop CPU that runs
|
||||||
|
`sm` at 5,484, so about 29x slower. On a T4 it reaches 8,320, and on that VM's own Xeon it
|
||||||
|
manages 336, a 25x GPU speedup. Treat GPU as a requirement rather than an optimization.
|
||||||
|
The 940MX cannot run `trf` at all, since current PyTorch wheels have dropped its sm_50
|
||||||
|
compute capability.
|
||||||
|
|
||||||
|
`sm`, `md` and `lg` are within about 15% of each other on CPU, which is smaller than the
|
||||||
|
gap in vector-table size suggests: the tok2vec is not the bottleneck, the parser and
|
||||||
|
lemmatizer are. Run-to-run spread on the laptop is roughly +/-10% depending on thermal
|
||||||
|
state, so treat differences under that as noise.

|
## 8. The `trf` tier: one fine-tuned ParsBERT
|
||||||
|
|
||||||
|
`configs/fa_core_news_trf.cfg` replaces the static-vector tok2vec with
|
||||||
|
`HooshvareLab/bert-base-parsbert-uncased`, fine-tuned during training. Trained on a rented
|
||||||
|
Colab T4 in 1h58m: 3000 steps, no early stop, the full learning-rate anneal.
|
||||||
|
|
||||||
|
### One corpus, because a transformer cannot be trained twice
|
||||||
|
|
||||||
|
The `sm`/`md`/`lg` tiers train `ner` as its own pipeline with its own embedded tok2vec and
|
||||||
|
then source it into the dep model. That is affordable because a hash-embed tok2vec is cheap.
|
||||||
|
A 162M-parameter encoder is not: fine-tuning it once per component would double GPU cost and
|
||||||
|
put two encoders in one wheel, and sourcing the second would collide on the `transformer`
|
||||||
|
component name.
|
||||||
|
|
||||||
|
So every component listens to a single shared transformer through a `TransformerListener`,
|
||||||
|
which requires one corpus carrying both the UD and NER annotation layers on the same `Doc`.
|
||||||
|
`scripts/merge_joint_corpus.py` builds it. The fusion is exact rather than approximate:
|
||||||
|
`corpus/perdt-ner/` was converted from the same `--merge-subtokens` CoNLL-U as
|
||||||
|
`corpus/merged/` with the same `--n-sents`, so the two DocBins are token-for-token identical.
|
||||||
|
The script asserts that per document and copies only `doc.ents` across. Char offsets are not
|
||||||
|
usable for the copy, because the two converters differ in trailing whitespace, which shifts
|
||||||
|
`char_span` off the token grid and returns None; the transfer goes by token index.
|
||||||
|
|
||||||
|
### Results against `lg`
|
||||||
|
|
||||||
|
| Metric | `lg` | `trf` | Delta |
|
||||||
|
| --- | ---: | ---: | ---: |
|
||||||
|
| `TAG_ACC` | 96.55 | 97.62 | +1.07 |
|
||||||
|
| `POS_ACC` | 96.68 | 97.63 | +0.95 |
|
||||||
|
| `MORPH_ACC` | 96.70 | 97.82 | +1.12 |
|
||||||
|
| `LEMMA_ACC` | 98.08 | 97.31 | -0.77 |
|
||||||
|
| `DEP_UAS` | 90.96 | 93.87 | +2.91 |
|
||||||
|
| `DEP_LAS` | 86.60 | 90.79 | +4.19 |
|
||||||
|
| `SENTS_F` | 99.18 | 97.35 | -1.83 |
|
||||||
|
| `ENTS_F` | 75.94 | 82.89 | +6.95 |
|
||||||
|
|
||||||
|
The parser gain is the headline: `DEP_LAS` 90.79 passes the hazm+ParsBERT reference of 89.34,
|
||||||
|
which no CPU tier reached. NER gains 6.95 F, almost all of it recall (71.09 to 81.76) at
|
||||||
|
higher precision, which is what a pretrained encoder buys on the difflib-transferred layer.
|
||||||
|
|
||||||
|
Two metrics regress. `SENTS_F` drops 1.83, most likely because `strided_spans` at
|
||||||
|
`window = 128, stride = 96` leaves 32 tokens of overlap, so tokens near a span edge see
|
||||||
|
truncated right context where the CPU tiers' tok2vec sees the whole doc. `LEMMA_ACC` drops
|
||||||
|
0.77 and is the one metric where a static-vector tier wins: `trainable_lemmatizer` reads a
|
||||||
|
single `reduce_mean`-pooled vector per token, while `lg` runs an edit-tree lemmatizer over
|
||||||
|
floret subwords that model Persian orthography directly. Neither is a training-length
|
||||||
|
problem; see TODO.md for the evidence that more steps do not help.
|
||||||
|
|
||||||
|
### Cost, and the licence problem
|
||||||
|
|
||||||
|
608 MB wheel, 2.6x `lg` and 45x `sm`. 187 words/s on the laptop CPU against `sm`'s 5,484
|
||||||
|
(§9), so this tier needs a GPU in production rather than merely benefiting from one.
|
||||||
|
|
||||||
|
ParsBERT's model card states no licence. §3.4 picked `HooshvareLab/roberta-fa-zwnj-base`
|
||||||
|
(Apache-2.0) for exactly this reason, and the published wheel therefore embeds weights whose
|
||||||
|
redistribution terms are unknown. `scripts/finalize_pipeline.py` reads the encoder name out
|
||||||
|
of the trained config and writes a redistribution warning into `meta.json` when the encoder
|
||||||
|
has no licence, so the artifact carries the caveat. Retraining on the Apache-2.0 encoder is a
|
||||||
|
one-line change to `name` in the config.
|
||||||
|
|
||||||
|
## 9. Throughput
|
||||||
|
|
||||||
|
Measured with `scripts/benchmark_throughput.py`, which times `nlp.pipe` and nothing else.
|
||||||
|
The `words/s` printed by `spacy benchmark accuracy` runs the Scorer's per-token alignment
|
||||||
|
inside the timed region, which is why the §7 numbers disagree with these and why one of them
|
||||||
|
was impossible.
|
||||||
|
|
||||||
|
Median of repeated passes over the 146-document PerDT test split (23,825 tokens), batch 32,
|
||||||
|
warmup discarded. Raw records in `metrics/throughput-*.json`.
|
||||||
|
|
||||||
|
| Tier | CPU, i5-7200U | GPU, GeForce 940MX | CPU, Xeon @ 2.00GHz | GPU, Tesla T4 |
|
||||||
|
| --- | ---: | ---: | ---: | ---: |
|
||||||
|
| `sm` | 5,484 | 10,235 | | |
|
||||||
|
| `md` | 5,408 | 9,058 | | |
|
||||||
|
| `lg` | 4,715 | 9,215 | | |
|
||||||
|
| `trf` | 187 | | 336 | 8,320 |
|
||||||
|
|
||||||
|
The CPU tiers sit within about 15% of each other, less than their vector-table sizes suggest,
|
||||||
|
so the tok2vec lookup is not the bottleneck; the parser and lemmatizer are. Run-to-run spread
|
||||||
|
on the laptop is roughly 10% either way with thermal state, and a background rsync halved
|
||||||
|
every number, so treat small differences as noise.
|
||||||
|
|
||||||
|
`trf` is 29x slower than `sm` on the same CPU. The T4 column and the Xeon column come from
|
||||||
|
the same Colab VM, giving a clean 25x GPU speedup for the transformer. The 940MX column is
|
||||||
|
empty for `trf` because current PyTorch wheels dropped sm_50, so that GPU cannot run it at
|
||||||
|
all.

`spacy benchmark accuracy` prints a speed number, but it is scoring-contaminated: the
|
||||||
|
Scorer's per-token alignment and per-type bookkeeping run inside the timed region, which
|
||||||
|
matters a lot for the cheap CPU tiers and understates them. This times `nlp.pipe` only.
|
||||||
|
|
||||||
|
Reported figure is the median of `--runs` passes over the same texts, after a discarded
|
||||||
|
warmup pass. Median rather than mean because the first CUDA kernel launches, cuBLAS
|
||||||
|
autotuning and any page-cache miss produce outliers that a mean would smear into the result.
|
||||||
|
|
||||||
|
Batch size matters far more for the trf tier than the CPU tiers (a transformer amortizes a
|
||||||
|
GEMM over the batch; a hash-embed tok2vec barely cares), so it is a parameter and gets
|
||||||
|
recorded in the output rather than being left implicit.

"""Fuse the UD annotation layer and the transferred NER layer into one DocBin.
|
||||||
|
|
||||||
|
The sm/md/lg tiers train `ner` as a separate pipeline with its own embedded tok2vec, then
|
||||||
|
source it into the dep model (project.yml `assemble-core`). That works because a hash-embed
|
||||||
|
tok2vec is cheap enough to train twice.
|
||||||
|
|
||||||
|
A transformer is not. Fine-tuning ParsBERT once per component would double GPU cost and
|
||||||
|
produce a package carrying two independent 162M-parameter encoders, and sourcing the second
|
||||||
|
one would collide on the `transformer` component name. So the trf tier trains every component
|
||||||
|
against a single shared transformer via TransformerListener, which requires a single corpus
|
||||||
|
carrying both annotation layers on the same Doc.
|
||||||
|
|
||||||
|
That fusion is exact, not approximate: `corpus/perdt-ner/` was produced by
|
||||||
|
scripts/transfer_perdt_ner.py from the same `--merge-subtokens` CoNLL-U as `corpus/merged/`,
|
||||||
|
then converted with the same `--n-sents`, so the two DocBins are token-for-token identical
|
||||||
|
(verified below and asserted at runtime). Only `doc.ents` is copied across; every other
|
||||||
|
annotation stays on the UD doc.
