SentenceTransformer based on google/bert_uncased_L-2_H-128_A-2

This is a sentence-transformers model finetuned from google/bert_uncased_L-2_H-128_A-2. It maps sentences & paragraphs to a 128-dimensional dense vector space and can be used for retrieval.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("swardiantara/bert-tiny-amazon_reviews-k5-fixed-euclidean")
# Run inference
sentences = [
    'Wrong size for my husband. I need to return them, unfortunately.',
    "Loved this hair brush! It's now much easier to detangle my frizzy hair after I wake up in the mornings. I wish I had found out about this much earlier. Thank you!",
    'These hooks work great for my boutique I have. I am able to hang scarves and different things from them including purses. They take up less space and last forever. The quality is excellent and so is the price!',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 128]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.9983, 0.9977],
#         [0.9983, 1.0000, 0.9985],
#         [0.9977, 0.9985, 1.0000]])

  Arrived broken. Manufacturer defect. Two of the legs of the base were not completely formed, so there was no way to insert the casters. I unpackaged the entire chair and hardware before noticing this. So, I'll spend twice the amount of time boxing up the whole useless thing and send it back with a 1-star review of part of a chair I never got to sit in. I will go so far as to include a picture of what their injection molding and quality assurance process missed though. I will be hesitant to buy again. It makes me wonder if there aren't missing structures and supports that don't impede the assembly process.	I ordered this a while ago, even using prime it took over a month to get here, now that I finally got it, I only receved 6 of the 12! Im a little upset. It's still funny, but would not recomend for someone who needs foam quick and in bulk like i do.	[1.0, 0.0]

I do not recommend.	[0.0, 0.25]

I really like Stila Products too, but it was just a clumpy mess on brush and hard to apply with the wand design. I had to be extra careful even just applying it because of how messy it was coming out of tube. Ended up returning it because Amazon is super great on their return policy on Prime items.	[0.0, 0.25]
