(except as stated in this section) patent license to make, have made,

| 77 |
-
use, offer to sell, sell, import, and otherwise transfer the Work,
|
| 78 |
-
where such license applies only to those patent claims licensable
|
| 79 |
-
by such Contributor that are necessarily infringed by their
|
| 80 |
-
Contribution(s) alone or by combination of their Contribution(s)
|
| 81 |
-
with the Work to which such Contribution(s) was submitted. If You
|
| 82 |
-
institute patent litigation against any entity (including a
|
| 83 |
-
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
| 84 |
-
or a Contribution incorporated within the Work constitutes direct
|
| 85 |
-
or contributory patent infringement, then any patent licenses
|
| 86 |
-
granted to You under this License for that Work shall terminate
|
| 87 |
-
as of the date such litigation is filed.
|
| 88 |
-
|
| 89 |
-
4. Redistribution. You may reproduce and distribute copies of the

| 91 |
-
modifications, and in Source or Object form, provided that You
|
| 92 |
-
meet the following conditions:
|
| 93 |
-
|
| 94 |
-
(a) You must give any other recipients of the Work or
|
| 95 |
-
Derivative Works a copy of this License; and
|
| 96 |
-
|
| 97 |
-
(b) You must cause any modified files to carry prominent notices
|
| 98 |
-
stating that You changed the files; and
|
| 99 |
-
|
| 100 |
-
(c) You must retain, in the Source form of any Derivative Works
|
| 101 |
-
that You distribute, all copyright, patent, trademark, and
|
| 102 |
-
attribution notices from the Source form of the Work,
|
| 103 |
-
excluding those notices that do not pertain to any part of
|
| 104 |
-
the Derivative Works; and
|
| 105 |
-
|
| 106 |
-
(d) If the Work includes a "NOTICE" text file as part of its
|
| 107 |
-
distribution, then any Derivative Works that You distribute must
|
| 108 |
-
include a readable copy of the attribution notices contained
|
| 109 |
-
within such NOTICE file, excluding those notices that do not
|
| 110 |
-
pertain to any part of the Derivative Works, in at least one
|
| 111 |
-
of the following places: within a NOTICE text file distributed
|
| 112 |
-
as part of the Derivative Works; within the Source form or
|
| 113 |
-
documentation, if provided along with the Derivative Works; or,
|
| 114 |
-
within a display generated by the Derivative Works, if and
|
| 115 |
-
wherever such third-party notices normally appear. The contents
|
| 116 |
-
of the NOTICE file are for informational purposes only and
|
| 117 |
-
do not modify the License. You may add Your own attribution
|
| 118 |
-
notices within Derivative Works that You distribute, alongside
|
| 119 |
-
or as an addendum to the NOTICE text from the Work, provided
|
| 120 |
-
that such additional attribution notices cannot be construed
|
| 121 |
-
as modifying the License.
|
| 122 |
-
|
| 123 |
-
You may add Your own copyright statement to Your modifications and
|
| 124 |
-
may provide additional or different license terms and conditions
|
| 125 |
-
for use, reproduction, or distribution of Your modifications, or
|
| 126 |
-
for any such Derivative Works as a whole, provided Your use,
|
| 127 |
-
reproduction, and distribution of the Work otherwise complies with
|
| 128 |
-
the conditions stated in this License.
|
| 129 |
-
|
| 130 |
-
5. Submission of Contributions. Unless You explicitly state otherwise,
|
| 131 |
-
any Contribution intentionally submitted for inclusion in the Work
|
| 132 |
-
by You to the Licensor shall be under the terms and conditions of
|
| 133 |
-
this License, without any additional terms or conditions.
|
| 134 |
-
Notwithstanding the above, nothing herein shall supersede or modify
|
| 135 |
-
the terms of any separate license agreement you may have executed
|
| 136 |
-
with Licensor regarding such Contributions.
|
| 137 |
-
|
| 138 |
-
6. Trademarks. This License does not grant permission to use the trade
|
| 139 |
-
names, trademarks, service marks, or product names of the Licensor,
|
| 140 |
-
except as required for reasonable and customary use in describing the
|
| 141 |
-
origin of the Work and reproducing the content of the NOTICE file.
|
| 142 |
-
|
| 143 |
-
7. Disclaimer of Warranty. Unless required by applicable law or
|
| 144 |
-
agreed to in writing, Licensor provides the Work (and each
|
| 145 |
-
Contributor provides its Contributions) on an "AS IS" BASIS,
|
| 146 |
-
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
| 147 |
-
implied, including, without limitation, any warranties or conditions
|
| 148 |
-
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
| 149 |
-
PARTICULAR PURPOSE. You are solely responsible for determining the
|
| 150 |
-
appropriateness of using or redistributing the Work and assume any
|
| 151 |
-
risks associated with Your exercise of permissions under this License.
|
| 152 |
-
|
| 153 |
-
8. Limitation of Liability. In no event and under no legal theory,
|
| 154 |
-
whether in tort (including negligence), contract, or otherwise,
|
| 155 |
-
unless required by applicable law (such as deliberate and grossly
|
| 156 |
-
negligent acts) or agreed to in writing, shall any Contributor be
|
| 157 |
-
liable to You for damages, including any direct, indirect, special,
|
| 158 |
-
incidental, or consequential damages of any character arising as a
|
| 159 |
-
result of this License or out of the use or inability to use the
|
| 160 |
-
Work (including but not limited to damages for loss of goodwill,
|
| 161 |
-
work stoppage, computer failure or malfunction, or any and all
|
| 162 |
-
other commercial damages or losses), even if such Contributor
|
| 163 |
-
has been advised of the possibility of such damages.
|
| 164 |
-
|
| 165 |
-
9. Accepting Warranty or Additional Liability. While redistributing
|
| 166 |
-
the Work or Derivative Works thereof, You may choose to offer,
|
| 167 |
-
and charge a fee for, acceptance of support, warranty, indemnity,
|
| 168 |
-
or other liability obligations and/or rights consistent with this
|
| 169 |
-
License. However, in accepting such obligations, You may act only
|
| 170 |
-
on Your own behalf and on Your sole responsibility, not on behalf
|
| 171 |
-
of any other Contributor, and only if You agree to indemnify,
|
| 172 |
-
defend, and hold each Contributor harmless for any liability
|
| 173 |
-
incurred by, or claims asserted against, such Contributor by reason
|
| 174 |
-
of your accepting any such warranty or additional liability.
|
| 175 |

## Model description
|
| 126 |
-
|
| 127 |
-
Language-agnostic BERT Sentence Encoder (LaBSE) is a BERT-based model trained for sentence embedding for 109 languages. The pre-training process combines masked language modeling with translation language modeling. The model is useful for getting multilingual sentence embeddings and for bi-text retrieval.
|
| 128 |
-
|
| 129 |
-
- Model: [HuggingFace's model hub](https://huggingface.co/setu4993/LaBSE).
|
| 130 |
-
- Paper: [arXiv](https://arxiv.org/abs/2007.01852).
|
| 131 |
-
- Original model: [TensorFlow Hub](https://tfhub.dev/google/LaBSE/1).
|
| 132 |
-
- Blog post: [Google AI Blog](https://ai.googleblog.com/2020/08/language-agnostic-bert-sentence.html).
|
| 133 |
-
|
| 134 |
-
## Usage
|
| 135 |
-
|
| 136 |
-
Using the model:
|
| 137 |
-
|
| 138 |
-
```python
|
| 139 |
-
import torch
|
| 140 |
-
from transformers import BertModel, BertTokenizerFast
|
| 141 |
-
|
| 142 |
-
|
| 143 |
-
tokenizer = BertTokenizerFast.from_pretrained("setu4993/LaBSE")
|
| 144 |
-
model = BertModel.from_pretrained("setu4993/LaBSE")
|
| 145 |
-
model = model.eval()
|
| 146 |
-
|
| 147 |
-
english_sentences = [
|
| 148 |
-
"dog",
|
| 149 |
-
"Puppies are nice.",
|
| 150 |
-
"I enjoy taking long walks along the beach with my dog.",
|
| 151 |
-
]
|
| 152 |
-
english_inputs = tokenizer(english_sentences, return_tensors="pt", padding=True)
|
| 153 |
-
|
| 154 |
-
with torch.no_grad():
|
| 155 |
-
english_outputs = model(**english_inputs)
|
| 156 |
-
```
|
| 157 |
-
|
| 158 |
-
To get the sentence embeddings, use the pooler output:
|
| 159 |
-
|
| 160 |
-
```python
|
| 161 |
-
english_embeddings = english_outputs.pooler_output
|
| 162 |
-
```
|
| 163 |
-
|
| 164 |
-
Output for other languages:
|
| 165 |
-
|
| 166 |
-
```python
|
| 167 |
-
italian_sentences = [
|
| 168 |
-
"cane",
|
| 169 |
-
"I cuccioli sono carini.",
|
| 170 |
-
"Mi piace fare lunghe passeggiate lungo la spiaggia con il mio cane.",
|
| 171 |
-
]
|
| 172 |
-
japanese_sentences = ["犬", "子犬はいいです", "私は犬と一緒にビーチを散歩するのが好きです"]
|
| 173 |
-
italian_inputs = tokenizer(italian_sentences, return_tensors="pt", padding=True)
|
| 174 |
-
japanese_inputs = tokenizer(japanese_sentences, return_tensors="pt", padding=True)
|
| 175 |
-
|
| 176 |
-
with torch.no_grad():
|
| 177 |
-
italian_outputs = model(**italian_inputs)
|
| 178 |
-
japanese_outputs = model(**japanese_inputs)
|
| 179 |
-
|
| 180 |
-
italian_embeddings = italian_outputs.pooler_output
|
| 181 |
-
japanese_embeddings = japanese_outputs.pooler_output
|
| 182 |
-
```
|
| 183 |
-
|
| 184 |
-
For similarity between sentences, an L2-norm is recommended before calculating the similarity:
|
| 185 |
-
|
| 186 |
-
```python
|
| 187 |
-
import torch.nn.functional as F
|
| 188 |
-
|
| 189 |
-
|
| 190 |
-
def similarity(embeddings_1, embeddings_2):
|
| 191 |
-
normalized_embeddings_1 = F.normalize(embeddings_1, p=2)
|
| 192 |
-
normalized_embeddings_2 = F.normalize(embeddings_2, p=2)
|
| 193 |
-
return torch.matmul(
|
| 194 |
-
normalized_embeddings_1, normalized_embeddings_2.transpose(0, 1)
|
| 195 |
-
)
|
| 196 |
-
|
| 197 |
-
|
| 198 |
-
print(similarity(english_embeddings, italian_embeddings))
|
| 199 |
-
print(similarity(english_embeddings, japanese_embeddings))
|
| 200 |
-
print(similarity(italian_embeddings, japanese_embeddings))
|
| 201 |
-
```
|
| 202 |
-
|
| 203 |
-
