-title: Customer Experience Bot Demo emoji: 🤖 colorFrom: blue colorTo: purple sdk: gradio sdk_version: "4.44.0" app_file: app.py pinned: false
-Customer Experience Bot Demo
-A cutting-edge Retrieval-Augmented Generation (RAG) and Context-Augmented Generation (CAG) powered Customer Experience (CX) bot, deployed on Hugging Face Spaces (free tier). Architected with over 5 years of AI expertise since 2020, this demo leverages advanced Natural Language Processing (NLP) pipelines to deliver high-fidelity, multilingual CX solutions for enterprise-grade applications in SaaS, HealthTech, FinTech, and eCommerce. The system showcases robust data preprocessing for call center datasets, integrating state-of-the-art technologies like Pandas for data wrangling, Hugging Face Transformers for embeddings, FAISS for vectorized retrieval, and FastAPI-compatible API design principles for scalable inference.
-Technical Architecture
-Retrieval-Augmented Generation (RAG) Pipeline
-The core of this CX bot is a RAG framework, designed to fuse retrieval and generation for contextually relevant responses. The pipeline employs:
-Hugging Face Transformers: Utilizes all-MiniLM-L6-v2, a lightweight Sentence-BERT model (~80MB), fine-tuned for semantic embeddings, to encode call center FAQs into dense vectors. This ensures efficient, high-dimensional representation of query semantics.
-FAISS (CPU): Implements a FAISS IndexFlatL2 for similarity search, enabling rapid retrieval of top-k FAQs (default k=2) via L2 distance metrics. FAISS’s CPU optimization ensures free-tier compatibility while maintaining sub-millisecond retrieval latency.
-Rule-Based Generation: Bypasses heavy LLMs (e.g., GPT-2) for free-tier constraints, using retrieved FAQ answers directly, achieving a simulated 95% accuracy while minimizing compute overhead.
-Context-Augmented Generation (CAG) Integration
-Building on RAG, the system incorporates CAG principles by enriching retrieved contexts with metadata (e.g., call_id, language) from call center CSVs. This contextual augmentation enhances response relevance, particularly for multilingual CX (e.g., English, Spanish), ensuring the bot adapts to diverse enterprise needs.
-Call Center Data Preprocessing with Pandas
-The bot ingests raw call center CSVs, which are often riddled with junk data (nulls, duplicates, malformed entries). Leveraging Pandas, the preprocessing pipeline:
-Data Ingestion: Parses CSVs with pd.read_csv, using io.StringIO for embedded data, with explicit quotechar and escapechar to handle complex strings.
-Junk Data Cleanup:
-Null Handling: Drops rows with missing question or answer using df.dropna().
-Duplicate Removal: Eliminates redundant FAQs via df[~df['question'].duplicated()].
-Short Entry Filtering: Excludes questions <10 chars or answers <20 chars with df[(df['question'].str.len() >= 10) & (df['answer'].str.len() >= 20)].
-Malformed Detection: Uses regex ([!?]{2,}|\b(Invalid|N/A)\b) to filter invalid questions.
-Standardization: Normalizes text (e.g., mo to month) and fills missing language with en.
-Output: Generates cleaned_call_center_faqs.csv for downstream modeling, with detailed cleanup stats (e.g., nulls, duplicates removed).
-Enterprise-Grade Modeling Compatibility
-The cleaned CSV is optimized for:
-Amazon SageMaker: Ready for training BERT-based models (e.g., bert-base-uncased) for intent classification or FAQ retrieval, deployable via SageMaker JumpStart.
-Azure AI: Compatible with Azure Machine Learning pipelines for fine-tuning models like DistilBERT in Azure Blob Storage, enabling scalable CX automation.
-LLM Integration: While not used in this free-tier demo, the cleaned data supports fine-tuning LLMs (e.g., distilgpt2) for generative tasks, leveraging your FastAPI experience for API-driven inference.
-Performance Monitoring and Visualization
-The bot includes a performance monitoring suite:
-Latency Tracking: Measures embedding, retrieval, and generation times using time.perf_counter(), reported in milliseconds.
-Accuracy Metrics: Simulates retrieval accuracy (95% if FAQs retrieved, 0% otherwise) for demo purposes.
-Visualization: Uses Matplotlib and Seaborn to plot a dual-axis chart (rag_plot.png):
-Bar Chart: Latency (ms) per stage (Embedding, Retrieval, Generation).
-Line Chart: Accuracy (%) per stage, with a muted palette for professional aesthetics.
-Gradio Interface for Interactive CX
-The bot is deployed via Gradio, providing a user-friendly interface:
-Input: Text query field for user inputs (e.g., “How do I reset my password?”).
-Outputs:
-Bot response (e.g., “Go to the login page, click ‘Forgot Password,’...”).
-Retrieved FAQs with question-answer pairs.
-Cleanup stats (e.g., “Cleaned FAQs: 6; removed 4 junk entries”).
-RAG pipeline plot for latency and accuracy.
-Styling: Custom dark theme CSS (#2a2a2a background, blue buttons) for a sleek, enterprise-ready UI.
-Setup
-Clone this repository to a Hugging Face Space (free tier, public).
-Add requirements.txt with dependencies (gradio==4.44.0, pandas==2.2.3, etc.).
-Upload app.py (embeds call center FAQs for seamless deployment).
-Configure to run with Python 3.9+, CPU hardware (no GPU).
-Usage
-Query: Enter a question in the Gradio UI (e.g., “How do I reset my password?”).
-Output:
-Response: Contextually relevant answer from retrieved FAQs.
-Retrieved FAQs: Top-k question-answer pairs.
-Cleanup Stats: Detailed breakdown of junk data removal (nulls, duplicates, short entries, malformed).
-RAG Plot: Visual metrics for latency and accuracy.
-Example:
-Query: “How do I reset my password?”
-Response: “Go to the login page, click ‘Forgot Password,’ and follow the email instructions.”
-Cleanup Stats: “Cleaned FAQs: 6; removed 4 junk entries: 2 nulls, 1 duplicates, 1 short, 0 malformed”
-Call Center Data Cleanup
-Preprocessing Pipeline:
-Null Handling: Eliminates incomplete entries with df.dropna().
-Duplicate Removal: Ensures uniqueness via df[~df['question'].duplicated()].
-Short Entry Filtering: Maintains quality with length-based filtering.
-Malformed Detection: Uses regex to identify and remove invalid queries.
-Standardization: Normalizes text and metadata for consistency.
-Impact: Produces high-fidelity FAQs for RAG/CAG pipelines, critical for call center CX automation.
-Modeling Output: The cleaned cleaned_call_center_faqs.csv is ready for:
-SageMaker: Fine-tuning BERT models for intent classification or FAQ retrieval.
-Azure AI: Training DistilBERT in Azure ML for scalable CX automation.
-LLM Fine-Tuning: Supports advanced generative tasks with LLMs via FastAPI endpoints.

-Free Tier Optimization: Lightweight with CPU-only dependencies, no GPU required.
-Extensibility: Ready for integration with enterprise CRMs (e.g., Salesforce) via FastAPI, and cloud deployments on AWS Lambda or Azure Functions.
-Purpose
-This demo showcases expertise in AI-driven CX automation, with a focus on call center data quality, built on over 5 years of experience in AI, NLP, and enterprise-grade deployments.
