# Model
|
6 |
miniALBERT is a recursive transformer model which uses cross-layer parameter sharing, embedding factorisation, and bottleneck adapters to achieve high parameter efficiency.
|
7 |
Since miniALBERT is a compact model, it is trained using a layer-to-layer distillation technique, using the bert-base model as the teacher. Currently, this model is trained for one epoch on the English subset of Wikipedia.
|
8 |
-
In terms of architecture, this model uses an embedding dimension of 128, a hidden size of 768, an MLP expansion rate of 4, and a reduction factor of 16 for bottleneck adapters. In general, this model uses 6 recursions and has a unique parameter count of 11 million parameters.

# Usage
|
11 |
+
Since miniALBERT uses a unique architecture it can not be loaded using ts.AutoModel for now. To load the model, first, clone the miniALBERT GitHub project, using the below code:
|
12 |
+
```bash
|
13 |
+
git clone https://github.com/nlpie-research/MiniALBERT.git
|
14 |
+
```
|
15 |
+
Then use the ```sys.path.append``` to add the miniALBERT files to your project and then import the miniALBERT modeling file using the below code:
|
16 |
+
```bash
|
17 |
+
import sys
|
18 |
+
sys.path.append("PATH_TO_CLONED_PROJECT/MiniALBERT/")
|
19 |
+
|
20 |
+
from minialbert_modeling import MiniAlbertForSequenceClassification, MiniAlbertForTokenClassification
|
21 |
+
```
|
22 |
+
Finally, load the model like a regular model in the transformers library using the below code:
|
23 |
+
```python
|
24 |
+
# For NER use the below code
|
25 |
+
model = MiniAlbertForTokenClassification.from_pretrained("nlpie/miniALBERT-128")
|
26 |
+
# For Sequence Classification use the below code
|
27 |
+
model = MiniAlbertForTokenClassification.from_pretrained("nlpie/miniALBERT-128")
|
28 |
+
```
