A vector database and search for positioning drones involves the following steps:

The first step would be to install all the required packages and libraries. We use Python in this sample:

import warnings 

warnings.filterwarnings(‘ignore’) 

from datasets import load_dataset 

from pinecone import Pinecone, ServerlessSpec 

from DLAIUtils import Utils 

import DLAIUtils  

import os 

import time 

import torch 

From tqdm.auto import tqdm 

We assume the elements are mapped as embeddings in a 384-dimensional dense vector space. 

A sample query would appear like this: 

query = `what is node nearest this element?` 

xq = model.encode(query) 

xq.shape 

(384,) 

The next step is to set up the Pinecone vector database to upsert embeddings into it. These database index vectors make search and retrieval easy by comparing values and finding those that are most like one-another 

utils = Utils() 

PINECONE_API_KEY = utils.get_pinecone_api_key() 

if INDEX_NAME in [index.name for index in pinecone.list_indexes()]: 

       pinecone.delete_index(INDEX_NAME) 

print(INDEX_NAME) 

pinecone.create_index(name=INDEX_NAME, dimension=model.get_sentence_embedding_dimension(), metric=’cosine’,spec=ServerlessSpec(cloud=’aws’, region=’us-west-2’)) 

index = pinecone.Index(INDEX_NAME) 

print(index) 

Then, the next step is to create embeddings for all the elements in the sample space and upsert them to Pinecone. 

batch_size=200 

vector_limit=10000 

elements=element[:vector_limit] 

import json 

for i in tqdm(range(0, len(elements), batch_size)): 

        i_end = min(i+batch_size, len(elements)) 

        ids = [str(x) for x in range(i, i_end)] 

        metadata = [{‘text’: text} for text in elements[i:i_end]] 

        xc = model.encode(elements[i:i_end]) 

        records = zip(ids, xc, metadata) 

        index.upsert(vectors=records) 

index.describe_index_stats() 

Then the query can be run on the embeddings and the top matches can be returned. 

def run_query(query): 

        embedding = model.encode(query).tolist() 

        results = index.query(top_k=10, vector=embedding, include_metadata=True, include_value) 

        for result in results[‘matches’]: 

                print(f”{round(result[‘score’], 2)}: {result[‘metadata’][‘node’]}”) 

run_query(“what is node nearest this element?”) 

With this, the embeddings-based search over elements is ready. In Azure, cosmos DB offers a similar semantic search and works as a similar vector database. 

The following code outlines the steps using Azure AI Search 

# configure the vector store settings, vector name is in the index of the search

endpoint: str = "<AzureSearchEndpoint>"

key: str = "<AzureSearchKey>"

index_name: str = "<VectorName>"

credential = AzureKeyCredential(key)

client = SearchClient(endpoint=endpoint,

                      index_name=index_name,

                      credential=credential)

# create embeddings 

embeddings: AzureOpenAIEmbeddings = AzureOpenAIEmbeddings(

    azure_deployment=azure_deployment,

    openai_api_version=azure_openai_api_version,

    azure_endpoint=azure_endpoint,

    api_key=azure_openai_api_key,

)

# create vector store

vector_store = AzureSearch(

    azure_search_endpoint=endpoint,

    azure_search_key=key,

    index_name=index_name,

    embedding_function=embeddings.embed_query,

)

# create a query

docs = vector_store.similarity_search(

    query=userQuery,

    k=3,

    search_type="similarity",

)

collections.insert_many(docs)
