SPCC

This is a sentence-transformers model finetuned from cl-nagoya/ruri-large. It maps sentences & paragraphs to a 1024-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 = [
    '引越しでアンテナ外して',
    '引っ越しに伴いアンテナ取り外しのみ依頼',
    '引越し先で新規アンテナ設置を依頼',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

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

Training Details

Training Dataset

Unnamed Dataset

• Size: 1,615 training samples
• Columns: anchor, positive, and negative
• Approximate statistics based on the first 1000 samples:

  	anchor	positive	negative
  type	string	string	string
  details	min: 3 tokens mean: 7.8 tokens max: 20 tokens	min: 4 tokens mean: 9.32 tokens max: 20 tokens	min: 3 tokens mean: 8.2 tokens max: 20 tokens

• Samples:

  anchor	positive	negative
  アンテナ向きがズレてスカパー映らない	アンテナ方向が狂い視聴できない	テレビ本体の電源が落ちて映らない
  ICカード無いせいでプレミアム見れない	ICカード未申請で一部チャンネル視聴不可	チューナー故障で全チャンネル映らない
  SONYチューナー壊れて受信不能	SONY製チューナー不具合で映像来ない	BSアンテナ設置ミスで映らない

• Loss: TripletLoss with these parameters:

  {
      "distance_metric": "TripletDistanceMetric.COSINE",
      "triplet_margin": 0.25
  }
