🧠 AI/ML Components

🔍 Vector Search Engine

// Semantic scheme matching with state-of-the-art embeddings
const embedder = await pipeline("feature-extraction", "Xenova/all-MiniLM-L6-v2");
const queryEmbedding = await embedder(userQuery);
const results = await collection.aggregate([
  {
    $vectorSearch: {
      queryVector: queryEmbedding,
      path: "embedding",
      numCandidates: 200,
      limit: 5
    }
  }
]);

🌐 Advanced Translation Pipeline

# IndicTrans2 for Indian languages
from IndicTransToolkit import IndicProcessor
ip = IndicProcessor(inference=True)
input_sentences = ["Government scheme information"]
batch = ip.preprocess_batch(input_sentences, src_lang="eng_Latn", tgt_lang="hin_Deva")
translated = model(batch)
output = ip.postprocess_batch(translated, lang="hin_Deva")

🧠 Multi-Model AI Pipeline

# Hugging Face Transformers integration
from transformers import pipeline, AutoTokenizer, AutoModel

# Sentiment analysis for community posts
sentiment_analyzer = pipeline("sentiment-analysis", 
                            model="cardiffnlp/twitter-roberta-base-sentiment-latest")

# Multilingual embeddings
embedding_model = AutoModel.from_pretrained("sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2")

# Google Gemini for conversational AI
model = genai.GenerativeModel('gemini-1.5-flash')
response = model.generate_content(f"""
You are an Indian Government Services Assistant.
Query: {user_query}
Schemes: {relevant_schemes}
Respond directly with helpful information.
""")

👁️ Computer Vision & OCR

# Advanced document processing pipeline
import pytesseract
from PIL import Image
from transformers import pipeline

# OCR with preprocessing
ocr_result = pytesseract.image_to_string(preprocessed_image, lang='eng+hin+ben')

# Document classification
doc_classifier = pipeline("image-classification", 
                         model="microsoft/dit-base-finetuned-rvlcdip")

# Form field extraction with NER
ner_pipeline = pipeline("ner", 
                       model="dbmdz/bert-large-cased-finetuned-conll03-english")
fields = ner_pipeline(ocr_result)

🛡️ Content Moderation

# Custom hate speech detection model
import pickle
from sklearn.feature_extraction.text import TfidfVectorizer

# Load pre-trained models
tfidf = pickle.load(open('vectorizer.pkl', 'rb'))
hate_model = pickle.load(open('model.pkl', 'rb'))

# Multi-language hate speech detection
transformed_text = transform_text(user_input)
vector_input = tfidf.transform([transformed_text])
is_hate_speech = hate_model.predict(vector_input)[0]
