SentenceTransformer based on sentence-transformers/all-MiniLM-L6-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-MiniLM-L6-v2. It maps sentences & paragraphs to a 384-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("gabrielegabellone/all-mini-mediterraneo-triplets-v4")
# Run inference
sentences = [
    'What is the State model?',
    'State contains the geometries of the states, in our specific case it contains only the entire geometries of the Italian state.',
    'The maps app contains State, Region, Province, Company, City, Particella, Map, MapCity, Property, Group, PropertyHasMap, Palette, PaletteColor, and Geotiff models.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

Training Details

Training Dataset

Unnamed Dataset

Size: 46,957 training samples
Columns: sentence_0, sentence_1, and sentence_2

Approximate statistics based on the first 1000 samples:

	sentence_0	sentence_1	sentence_2
type	string	string	string
details	min: 7 tokens mean: 9.62 tokens max: 15 tokens	min: 21 tokens mean: 35.4 tokens max: 68 tokens	min: 21 tokens mean: 73.85 tokens max: 239 tokens

Samples:

sentence_0	sentence_1	sentence_2
`How to restore a database dump?`	`Copy the dump file to data/postgresql folder, then inside the database container run pg_restore -U $POSTGRES_USER -d $POSTGRES_DB --clean --if-exists /var/lib/postgresql/data/db_backup.dump`	filter(id__in=ids_dataframe1) ids_dataframe2 = df2. split(',') maps = Map. objects. filter(id__in=ids_dataframe2) if not provinces or not maps: return Response('Provinces or maps not found', status=status. HTTP_404_NOT_FOUND) ``` 2. Then we use the **Geodataframe.
`What is the Region model?`	`Region contains the geometries of the regions, in our specific case it only contains the geometries of the Italian regions.`	The command allows loading data into the project based on a compiled excel file. Allows loading data on scenarios, shapefiles, palettes, software, particles and companies. 1. Run the command:: bash<br> python manage. py flow<br> 2. Choose the type of data to load: ``` Executing consistency checks. Load scenarios data. (y/n): n Load softwares data.
`What is the generategeotiff command?`	`This command generates Geotiff instances from a shapefile. For each Property present in the shapefile, a Geotiff instance will be created.`	MINIO_ROOT_USER=minio12345 MINIO_ROOT_PASSWORD=minio12345 MINIO_ENDPOINT=minio:9000 MINIO_EXTERNAL_ENDPOINT=localhost:9000 #CDN MINIO_USE_HTTPS=False MINIO_EXTERNAL_ENDPOINT_USE_HTTPS=False #true online PGADMIN_DEFAULT_EMAIL=admin@admin. com PGADMIN_DEFAULT_PASSWORD=strongpassword VERSION=1. 0. 0 SHAPEFILE_VERSION=gadm41_ITA_ ```.
