x100 smaller with less than 0.5 accuracy drop vs. distilbert-base-uncased-finetuned-sst-2-english
Model description
2 Layers Bilstm model finetuned on SST-2 and distlled from RoBERTa teacher
distilbert-base-uncased-finetuned-sst-2-english: 92.2 accuracy, 67M parameters
moshew/distilbilstm-finetuned-sst-2-english: 91.9 accuracy, 0.66M parameters
How to get started with the model
Example on SST-2 test dataset classification:
!pip install datasets
from datasets import load_dataset
import numpy as np
from sklearn.metrics import accuracy_score
from keras.preprocessing.text import Tokenizer
from keras.utils import pad_sequences
import tensorflow as tf
from huggingface_hub import from_pretrained_keras
from datasets import load_dataset
sst2 = load_dataset("SetFit/sst2")
augmented_sst2_dataset = load_dataset("jmamou/augmented-glue-sst2")
# Tokenize our training data
tokenizer = Tokenizer(num_words=10000)
tokenizer.fit_on_texts(augmented_sst2_dataset['train']['sentence'])
# Encode test data sentences into sequences
test_sequences = tokenizer.texts_to_sequences(sst2['test']['text'])
# Pad the test sequences
test_padded = pad_sequences(test_sequences, padding = 'post', truncating = 'post', maxlen=64)
reloaded_model = from_pretrained_keras('moshew/distilbilstm-finetuned-sst-2-english')
#Evaluate model on SST2 test data (GLUE)
pred=reloaded_model.predict(test_padded)
pred_bin = np.argmax(pred,1)
accuracy_score(pred_bin, sst2['test']['label'])
0.9187259747391543
