+- text: Saudi Arabia–United Arab Emirates relations However, the UAE and Saudi Arabia
+    continue to take somewhat differing stances on regional conflicts such the Yemeni
+    Civil War, where the UAE opposes Al-Islah, and supports the Southern Movement,
+    which has fought against Saudi-backed forces, and the Syrian Civil War, where
+    the UAE has disagreed with Saudi support for Islamist movements.[4]
+- text: Economy of New Zealand New Zealand's diverse market economy has a sizable
+    service sector, accounting for 63% of all GDP activity in 2013.[17] Large scale
+    manufacturing industries include aluminium production, food processing, metal
+    fabrication, wood and paper products. Mining, manufacturing, electricity, gas,
+    water, and waste services accounted for 16.5% of GDP in 2013.[17] The primary
+    sector continues to dominate New Zealand's exports, despite accounting for 6.5%
+    of GDP in 2013.[17]

+- text: Get Over It (Eagles song) "Get Over It" is a song by the Eagles released as
+    a single after a fourteen-year breakup. It was also the first song written by
+    bandmates Don Henley and Glenn Frey when the band reunited. "Get Over It" was
+    played live for the first time during their Hell Freezes Over tour in 1994. It
+    returned the band to the U.S. Top 40 after a fourteen-year absence, peaking at
+    No. 31 on the Billboard Hot 100 chart. It also hit No. 4 on the Billboard Mainstream
+    Rock Tracks chart. The song was not played live by the Eagles after the "Hell
+    Freezes Over" tour in 1994. It remains the group's last Top 40 hit in the U.S.

+# Sparse CSR model trained on Natural Questions
+
+This is a [CSR Sparse Encoder](https://www.sbert.net/docs/sparse_encoder/usage/usage.html) model finetuned from [mixedbread-ai/mxbai-embed-large-v1](https://huggingface.co/mixedbread-ai/mxbai-embed-large-v1) 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 4096-dimensional sparse vector space  with 256 maximum active dimensions  and can be used for semantic search and sparse retrieval.

+## 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/csr-mxbai-embed-large-v1-nq-cos-sim-scale-20-gamma-1")
+# Run inference

+    "Joe Ranft Ranft reunited with Lasseter when he was hired by Pixar in 1991 as their head of story.[1] There he worked on all of their films produced up to 2006; this included Toy Story (for which he received an Academy Award nomination) and A Bug's Life, as the co-story writer and others as story supervisor. His final film was Cars. He also voiced characters in many of the films, including Heimlich the caterpillar in A Bug's Life, Wheezy the penguin in Toy Story 2, and Jacques the shrimp in Finding Nemo.[1]",
+    'Wonderful Tonight "Wonderful Tonight" is a ballad written by Eric Clapton. It was included on Clapton\'s 1977 album Slowhand. Clapton wrote the song about Pattie Boyd.[1] The female vocal harmonies on the song are provided by Marcella Detroit (then Marcy Levy) and Yvonne Elliman.',

The river has achieved lasting fame as the main watercourse of the city of Rome, founded on its eastern banks.</code> |

Tom borrows Gatsby's yellow Rolls Royce to drive up to the city. On the way to New York City, Tom makes a detour at a gas station in "the Valley of Ashes", a run-down part of Long Island. The owner, George Wilson, shares his concern that his wife, Myrtle, may be having an affair. This unnerves Tom, who has been having an affair with Myrtle, and he leaves in a hurry.</code>                                       |
