vectin

vectin。

Vectin是一個簡單的矢量存儲，從頭開始構建，用於文本嵌入和相似性搜索。

支持嵌入矢量存儲的磁盤持久性。

例子

 # Tokens Size
max_tokens_count = 768

vectin = Vectin ( name = "short_term_logs" , max_tokens = max_tokens_count , persist_data = True , data_storage_path = None )

# Build Corpus
corpus = [
    "Machine learning and artificial intelligence are gaining popularity." ,
    "Python is widely used in data science and web development." ,
    "Data science involves analyzing large datasets to extract meaningful insights." ,
    "Artificial intelligence is transforming various industries." ,
    "Data Science is the most popular field of study in 2021." ,
]

# Preprocess
corpus = vectin . chunk_sentences_to_max_tokens ( sentences = corpus , max_tokens = max_tokens_count )

# Encode
corpus_vectors = vectin . encode ( corpus )

# Save
vectin . insert_vectors ( corpus_vectors )

# Similarity Search
query = "data science"
result = vectin . similarity_search ( query )
print ( result )

# Disk Persistence
vectin . save_to_disk ()
