GoatHerder/Ariadne-Laya-Spam

Ariadne Laya Spam

Classifies SMS text as ham or spam. This 4.2 MB specialist interface runs on a shared frozen Laya base. Switching between compatible Ariadne specialists replaces about 1 million parameters, while the 421 million parameter base stays in memory. Each specialist uses its own small interface.

Use

Install the included Python wheel from this downloaded model folder:

pip install ./ariadne_specialists-0.2.0a1-py3-none-any.whl

import ariadne
from ariadne.specialists import Spam

model = ariadne.load_specialist(Spam, model=".")
result = model('Can you call me when you get home?')
print(result.label, result.score)

The base downloads automatically and is cached. Choose a device with device="cpu" or device="cuda:1". A list of inputs returns a list of results. Scores have not been recalibrated for this task.

Load from Hugging Face

After installing the included wheel, you can load this repository directly:

import ariadne
from ariadne.specialists import Spam

model = ariadne.load_specialist(Spam, model="GoatHerder/Ariadne-Laya-Spam")

Use the explicit model= argument with this preview wheel. The interface and pinned base are downloaded automatically and cached. Pass revision="<commit hash>" to pin a particular interface version.

Interface

The interface is a 1,024 × 1,024 linear projection plus a 1,024-element bias: 1,049,600 trainable parameters. It sits after the base's native embeddings and before encoder block 0. It starts as the identity; training updates only this projection. The shared base has 421,293,827 parameters. Compatible specialists share one resident base in the same Python process and on the same device.

Results

Local evaluation uses the same 515 inputs for every model. Accuracy is per decision; macro-F1 averages the task's classes (and flag namespaces for Privacy).

Model	Accuracy	Macro-F1
Base Laya	83.30%	74.46%
Ariadne Spam	99.22%	98.17%
hari-krishna-ai/sms-spam-minilm-l6	99.42%	98.63%
TF-IDF + logistic regression	99.03%	97.66%

Same source dataset; exact training row overlap with our test is unverified. This table does not establish a common unseen-test ranking. metrics.json records model revisions, comparison methods, per-class results and existing-task retention.

Training and scope

Trained on ucirvine/sms_spam, revision cae486f927c250fe1d4a5b55f11357964ed1646c. Prepared train/validation/test sizes: 4,098 / 517 / 515. Overlength exclusions: {'train': 0, 'validation': 0, 'test': 0}.

One seed (0); epoch 2 selected by validation loss, training stopped after epoch 10. LR 1e-4, minimum 10 epochs, patience 3. Only the 1,049,600 exact-identity-initialized interface parameters were trained. The original embeddings, 28 encoder blocks and decision heads stayed frozen and in evaluation mode. Deterministic GPU settings were enabled.

• Custom grouped split of the historical UCI SMS corpus. This does not measure modern email phishing.
• Label-independent lexical groups at cosine >=0.90; excluded 0 training rows related to official test. Semantic independence is unverified.

English only. Unsupported or ambiguous inputs still receive a prediction. Source datasets retain their own licences. This checkpoint is one training run; it does not establish across-seed variance.
