Reranker ModernBERT Base Gooaq Bce

🚀 ModernBERT-base trained on GooAQ

This is a Cross Encoder model that computes scores for text pairs, which can be used for text reranking and semantic search. It is fine - tuned from answerdotai/ModernBERT-base using the sentence-transformers library.

✨ Features

• Computes scores for pairs of texts, useful for text reranking and semantic search.
• Based on the powerful answerdotai/ModernBERT-base model.

📦 Installation

First, you need to install the Sentence Transformers library:

pip install -U sentence-transformers

💻 Usage Examples

Basic Usage

from sentence_transformers import CrossEncoder

    how do you find mass?	Divide the object's weight by the acceleration of gravity to find the mass. You'll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you're measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.	1
    how do you find mass?	In general use, 'High Mass' means a full ceremonial Mass, most likely with music, and also with incense if they're particularly traditional. ... Incense is used quite a lot. Low Mass in the traditional rite is celebrated by one priest, and usually only one or two altar servers.	0
    how do you find mass?	A neutron has a slightly larger mass than the proton. These are often given in terms of an atomic mass unit, where one atomic mass unit (u) is defined as 1/12th the mass of a carbon-12 atom. You can use that to prove that a mass of 1 u is equivalent to an energy of 931.5 MeV.	0
