- text: Rollin' (Limp Bizkit song) The music video was filmed atop the South Tower
    of the former World Trade Center in New York City. The introduction features Ben
    Stiller and Stephen Dorff mistaking Fred Durst for the valet and giving him the
    keys to their Bentley Azure. Also making a cameo is break dancer Mr. Wiggles.
    The rest of the video has several cuts to Durst and his bandmates hanging out
    of the Bentley as they drive about Manhattan. The song Ben Stiller is playing
    at the beginning is "My Generation" from the same album. The video also features
    scenes of Fred Durst with five girls dancing in a room. The video was filmed around
    the same time as the film Zoolander, which explains Stiller and Dorff's appearance.
    Fred Durst has a small cameo in that film.

- text: Lionel Messi Born and raised in central Argentina, Messi was diagnosed with
    a growth hormone deficiency as a child. At age 13, he relocated to Spain to join
    Barcelona, who agreed to pay for his medical treatment. After a fast progression
    through Barcelona's youth academy, Messi made his competitive debut aged 17 in
    October 2004. Despite being injury-prone during his early career, he established
    himself as an integral player for the club within the next three years, finishing
    2007 as a finalist for both the Ballon d'Or and FIFA World Player of the Year
    award, a feat he repeated the following year. His first uninterrupted campaign
    came in the 2008–09 season, during which he helped Barcelona achieve the first
    treble in Spanish football. At 22 years old, Messi won the Ballon d'Or and FIFA
    World Player of the Year award by record voting margins.
- text: 'Send In the Clowns "Send In the Clowns" is a song written by Stephen Sondheim

    for the 1973 musical A Little Night Music, an adaptation of Ingmar Bergman''s

    film Smiles of a Summer Night. It is a ballad from Act Two, in which the character

    Desirée reflects on the ironies and disappointments of her life. Among other things,

    she looks back on an affair years earlier with the lawyer Fredrik, who was deeply

    in love with her but whose marriage proposals she had rejected. Meeting him after

    so long, she realizes she is in love with him and finally ready to marry him,

    but now it is he who rejects her: he is in an unconsummated marriage with a much

    younger woman. Desirée proposes marriage to rescue him from this situation, but

    he declines, citing his dedication to his bride. Reacting to his rejection, Desirée

    sings this song. The song is later reprised as a coda after Fredrik''s young wife

    runs away with his son, and Fredrik is finally free to accept Desirée''s offer.[1]'

# Inference-free SPLADE bert-base-uncased trained on Natural-Questions tuples

This is a [Asymmetric Inference-free SPLADE Sparse Encoder](https://www.sbert.net/docs/sparse_encoder/usage/usage.html) model trained on the [natural-questions](https://huggingface.co/datasets/sentence-transformers/natural-questions) dataset using the [sentence-transformers](https://www.SBERT.net) library. It maps sentences & paragraphs to a 30522-dimensional sparse vector space   and can be used for semantic search and sparse retrieval.
## Model Details

### Model Description

## Usage

### Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

```bash

pip install -U sentence-transformers

```

Then you can load this model and run inference.
```python

from sentence_transformers import SparseEncoder



# Download from the 🤗 Hub

model = SparseEncoder("tomaarsen/inference-free-splade-bert-base-uncased-nq-3e-3-lambda-corpus-1e-3-idf-lr-2e-5-lr")

# Run inference

sentences = [

    'is send in the clowns from a musical',

    'Send In the Clowns "Send In the Clowns" is a song written by Stephen Sondheim for the 1973 musical A Little Night Music, an adaptation of Ingmar Bergman\'s film Smiles of a Summer Night. It is a ballad from Act Two, in which the character Desirée reflects on the ironies and disappointments of her life. Among other things, she looks back on an affair years earlier with the lawyer Fredrik, who was deeply in love with her but whose marriage proposals she had rejected. Meeting him after so long, she realizes she is in love with him and finally ready to marry him, but now it is he who rejects her: he is in an unconsummated marriage with a much younger woman. Desirée proposes marriage to rescue him from this situation, but he declines, citing his dedication to his bride. Reacting to his rejection, Desirée sings this song. The song is later reprised as a coda after Fredrik\'s young wife runs away with his son, and Fredrik is finally free to accept Desirée\'s offer.[1]',

embeddings = model.encode(sentences)

print(embeddings.shape)

# (3, 30522)



# Get the similarity scores for the embeddings

similarities = model.similarity(embeddings, embeddings)

print(similarities.shape)

# [3, 3]
