SentenceTransformer based on Snowflake/snowflake-arctic-embed-m-v2.0

This is a sentence-transformers model finetuned from Snowflake/snowflake-arctic-embed-m-v2.0 . It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

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("sentence_transformers_model_id")
# Run inference
sentences = [
    'How does the new Eurostat methodology differ in scope from the indicators used in this Directive for calculating energy consumption?',
    '(29) The methodology for calculation of primary energy consumption and final energy consumption is aligned with the new Eurostat methodology, but the indicators used for the purpose of this Directive have a different scope, in that they exclude ambient energy and include energy consumption in international aviation for the targets in primary energy consumption and final energy consumption. The use of new indicators also implies that any changes in energy consumption of blast furnaces are now only reflected in primary energy consumption.',
    '(92) InvestEU is the Union flagship programme to boost investment, especially the green and digital transition, by providing financing and technical assistance, for instance through blending mechanisms. Such an approach contributes to crowd in additional public and private capital. Moreover, Member States are encouraged to contribute to the InvestEU Member State compartment to support financial products available to net-zero technology manufacturing, without prejudice to applicable State aid rules.',

  The regulation's applicability extends to various stakeholders involved in AI systems, including providers, deployers, importers, and manufacturers, regardless of their location. It specifically addresses high-risk AI systems and outlines the limitations of its scope, particularly concerning national security and military applications. Additionally, it clarifies that it does not interfere with the responsibilities of member states regarding national security or the operations of public authorities and international organizations in specific contexts.

  What measures must AIFMs implement to ensure they do not rely solely on credit ratings for assessing the creditworthiness of AIFs' assets?	▼M1 The measures specifying the risk-management systems referred to in point (a) of the first subparagraph shall ensure that the AIFMs are prevented from relying solely or mechanistically on credit ratings, as referred to in the first subparagraph of paragraph 2, for assessing the creditworthiness of the AIFs’ assets. ▼B Article 16 Liquidity management 1. AIFMs shall, for each AIF that they manage which is not an unleveraged closed- ended AIF, employ an appropriate liquidity management system and adopt procedures which enable them to monitor the liquidity risk of the AIF and to ensure that the liquidity profile of the investments of the AIF complies with its underlying obligations.
