- text: "Tissue-based diagnostics and research is incessantly evolving with the development of new molecular tools. It has long been realized that immunohistochemistry can add an important new level of information on top of morphology and that protein expression patterns in a cancer may yield crucial diagnostic and prognostic information. We have generated an immunohistochemistry-based map of protein expression profiles in normal tissues, cancer and cell lines." |

This is the finetuned model presented in **MIReAD: a simple method for learning high-quality representations from |
|
scientific documents (ACL 2023)**. |
|
|
|
We trained MIReAD on >500,000 PubMed and arXiv abstracts across over 2,000 journal classes. MIReAD was initialized with SciBERT weights and finetuned to predict journal class based on the abstract and title of the paper. MIReAD uses SciBERT's tokenizer. |
|
|
|
Overall, with MIReAD you can: |
|
* extract semantically meaningful representation using paper's abstact |
|
* predict journal class based on paper's abstract |
|
|
|
To load the MIReAD model: |
|
```python |
|
from transformers import BertForSequenceClassification, AutoTokenizer |
|
|
|
mpath = 'arazd/miread' |
|
model_hub = BertForSequenceClassification.from_pretrained(mpath) |
|
tokenizer = AutoTokenizer.from_pretrained(mpath) |
|
``` |
|
|
|
To use MIReAD for feature extraction and classification: |
|
```python |
|
# sample abstract text |
|
abstr = 'Learning semantically meaningful representations from scientific documents can ...' |
|
source_len = 512 |
|
inputs = tokenizer(abstr, |
|
max_length = source_len, |
|
pad_to_max_length=True, |
|
truncation=True, |
|
return_tensors="pt") |
|
|
|
# classification (getting logits over 2,734 journal classes) |
|
out = model(**inputs) |
|
logits = out.logits |
|
|
|
# feature extraction (getting 768-dimensional feature profiles) |
|
out = model.bert(**inputs) |
|
# IMPORTANT: use [CLS] token representation as document-level representation (hence, 0th idx) |
|
feature = out.last_hidden_state[:, 0, :] |
|
|
|
``` |
