# Masked Language Modeling
|
34 |
+
|
35 |
+
## 📌 Model Overview
|
36 |
+
This model is a fine-tuned version of **distilbert-base-uncased** on the **IMDb dataset** using the **Masked Language Modeling (MLM)** objective.
|
37 |
+
It is designed for **domain adaptation**, helping DistilBERT better understand the linguistic style of IMDb movie reviews.
|

+

+
|
41 |
+
## ✨ What this model does
|
42 |
+
|
43 |
+
- Learns to predict masked tokens in movie-review text (MLM / `fill-mask`).
|
44 |
+
- Helpful as a **domain-adapted backbone** for:
|
45 |
+
- Sentiment analysis on reviews
|
46 |
+
- Topic classification / intent
|
47 |
+
- Review-specific QA / RAG preprocessing
|
48 |
+
- Any task that benefits from in-domain representations

## 🚀 Quickstart
|
53 |
+
|
54 |
+
### Use with `pipeline` (Fill-Mask)
|
55 |
+
|
56 |
+
```python
|
57 |
+
from transformers import pipeline
|
58 |
+
|
59 |
+
nlp = pipeline("fill-mask", model="azherali/distilbert-imdb_mask_model")
|
60 |
+
|
61 |
+
nlp("This movie was absolutely [MASK] and the performances were stunning.")
|
62 |
+
# [{'sequence': 'this movie was absolutely fantastic ...', 'score': ...}, ...]
|
63 |
+
|
64 |
+
for x in pipe(text):
|
65 |
+
print(x["sequence"])
|
66 |
+
|
67 |
+
output:
|
68 |
+
# this movie was absolutely fantastic and the performances were stunning.
|
69 |
+
# this movie was absolutely stunning and the performances were stunning.
|
70 |
+
# this movie was absolutely beautiful and the performances were stunning.
|
71 |
+
# this movie was absolutely brilliant and the performances were stunning.
|
72 |
+
# this movie was absolutely wonderful and the performances were stunning.
|
73 |
+
|
74 |
+
```
|
75 |
+
### Use with AutoModel (programmatic logits)
|
76 |
+
|
77 |
+
|
78 |
+
```python
|
79 |
+
import torch
|
80 |
+
from transformers import AutoModelForMaskedLM,AutoTokenizer
|
81 |
+
|
82 |
+
model_checkpoint = "azherali/distilbert-imdb_mask_model"
|
83 |
+
|
84 |
+
model = AutoModelForMaskedLM.from_pretrained(model_checkpoint)
|
85 |
+
tokenizer = AutoTokenizer.from_pretrained(model_checkpoint)
|
86 |
+
|
87 |
+
text ="This movie was absolutely [MASK] and the performances were stunning."
|
88 |
+
|
89 |
+
inputs = tokenizer(text, return_tensors="pt")
|
90 |
+
token_logits = model(**inputs).logits
|
91 |
+
# Find the location of [MASK] and extract its logits
|
92 |
+
mask_token_index = torch.where(inputs["input_ids"] == tokenizer.mask_token_id)[1]
|
93 |
+
mask_token_logits = token_logits[0, mask_token_index, :]
|
94 |
+
# Pick the [MASK] candidates with the highest logits
|
95 |
+
top_5_tokens = torch.topk(mask_token_logits, 5, dim=1).indices[0].tolist()
|
96 |
+
|
97 |
+
for token in top_5_tokens:
|
98 |
+
print(f"'>>> {text.replace(tokenizer.mask_token, tokenizer.decode([token]))}'")
|
99 |
+
|
100 |
+
```
|
101 |
+
|
102 |
+
|
103 |
+
|
104 |
+
|
105 |
+
