# pierluigic/xl-lexeme |
|
|
|
This is model is based on [sentence-transformers](https://www.SBERT.net): It maps target word in sentences to a 1024 dimensional dense vector space and can be used for tasks like clustering or semantic search. |
|
|
|
<!--- Describe your model here --> |
|
|
|
## Usage (WordTransformer) |
|
|
|
Install the library: |
|
|
|
``` |
|
git clone git@github.com:pierluigic/xl-lexeme.git |
|
cd xl-lexeme |
|
pip3 install . |
|
``` |
|
|
|
Then you can use the model like this: |
|
|
|
```python |
|
from WordTransformer import WordTransformer, InputExample |
|
|
|
model = WordTransformer('pierluigic/xl-lexeme') |
|
examples = InputExample(texts="the quick fox jumps over the lazy dog", positions=[10,13]) |
|
fox_embedding = model.encode(examples) #The embedding of the target word "fox" |
|
``` |
|
|
|
|
|
|
|
## Training |
|
The model was trained with the parameters: |
|
|
|
**DataLoader**: |
|
|
|
`torch.utils.data.dataloader.DataLoader` of length 16531 with parameters: |
|
``` |
|
{'batch_size': 16, 'sampler': 'torch.utils.data.sampler.RandomSampler', 'batch_sampler': 'torch.utils.data.sampler.BatchSampler'} |
|
``` |
|
|
|
**Loss**: |
|
|
|
`sentence_transformers.losses.ContrastiveLoss.ContrastiveLoss` with parameters: |
|
``` |
|
{'distance_metric': 'SiameseDistanceMetric.COSINE_DISTANCE', 'margin': 0.5, 'size_average': True} |
|
``` |
