Which open-weight model does Quanta use?Passed

Quanta uses the open-weight Qwen2.5 model running through Ollama.

How does NewsIntel turn text into features?Passed

NewsIntel cleans, normalises, tokenises, and stems the text using NLTK to prepare the input for feature extraction. It then uses a TF-IDF Vectoriser to transform those preprocessed tokens into numerical sparse matrices based on Term Frequency-Inverse Document Frequency weightings. This process converts the raw news text into structured features that the classifier can evaluate.

What web framework serves NewsIntel?Passed

NewsIntel is served using the Flask web framework. Sangam built it as an NLP platform that classifies news as real or fake using a machine learning classifier.

Which clustering algorithm does Customer Intelligence use?Passed

Customer Intelligence uses K-Means clustering along with RFM features to segment customer behavior.

Where is the Customer Intelligence API deployed?Passed

The Customer Intelligence API is deployed on an AWS EC2 instance and kept running with systemd. You can check out the project page to learn more about how it works.

What apps use the Customer Intelligence API?Passed

The Customer Intelligence API is used by two client applications: a Streamlit web app and a native Android app built with Kotlin and Jetpack Compose. Both apps communicate with the same FastAPI prediction backend hosted on AWS EC2.

What ROC-AUC does the credit risk model get?Passed

The credit risk model achieves a ROC-AUC score of 75.99 percent, or about 0.76. This metric shows how well the model ranks risky loan applicants above safe ones.

What decision threshold does the credit risk model use?Passed

The credit risk model uses a custom decision threshold of 0.15, or 15 percent, instead of the default 0.50. This lower threshold helps catch more risky applicants by trading off some precision for higher recall.

What kind of model is the credit risk predictor?Passed

Sangam's credit risk predictor uses a HistGradientBoostingClassifier built inside a scikit-learn pipeline. It evaluates applicant financial, demographic, and credit history data to estimate loan default probabilities.

Which vector store does his RAG assistant use?Passed

Sangam's AI and ML RAG assistant uses an in-memory FAISS vector store to store the text chunk embeddings. This allows the system to quickly retrieve the most relevant sections of the document to answer user questions.

How does AI Signal deliver its signals?Passed

AI Signal uses an automated screener to pull market data and score stocks based on RSI indicators. It then delivers these daily stock signals straight to your phone through a Telegram bot.

Which indicator does AI Signal score stocks on?Passed

Sangam built AI Signal to score stocks on RSI-based indicators, pulling market data with yfinance and sending daily signals directly to Telegram.

What was his final-year project?Passed

Sangam's final-year project is NewsIntel, an NLP platform that classifies news as real or fake. It uses NLTK preprocessing, TF-IDF vectorisation, and a scikit-learn Passive Aggressive classifier, served through Flask with Google sign-in and Supabase. I can open the NewsIntel case study for you.

Which classifier does NewsIntel use?Passed

NewsIntel uses a scikit-learn Passive Aggressive classifier to evaluate the credibility of news articles. Sangam trained this model on TF-IDF features and NLTK-processed text as part of his final-year engineering project.
