Special thanks to Mega Satish for her meaningful contributions, guidance, and support that helped shape this work.
Depression Detection Using Tweets is a specialized Machine Learning framework designed to translate complex linguistic patterns into empirical psychological insights. This repository prioritizes high-dimensional feature extraction and probabilistic classification to provide a robust baseline for sentiment analysis within the context of mental health monitoring.
- Linguistic Determinism: The system utilizes deep NLP preprocessing, including lemmatization and entity normalization, to ensure that the semantic core of a tweet is preserved regardless of slang or stylistic variation.
- Vector-Space Inference: By leveraging Support Vector Machines (SVM) and TF-IDF vectorization, the model maps textual input into a multi-dimensional hyperplane, enabling precise binary classification of depressive sentiment.
- Architectural Efficiency: The backend is architected for low-latency serving via Flask, ensuring that model inference and result rendering occur in sub-second cycles, critical for interactive user feedback.
Tip
NLP Pipeline Optimization
To maximize classification reliability, the engine employs a multi-stage linguistic filter. Stop-word suppression and morphological analysis strip away structural noise, while the en_core_web_lg transformer model contextualizes surviving tokens. This ensures the classifier’s weights are strictly coupled with affective indicators, minimizing the false-positive skew common in generalized sentiment analysis models.
| Feature | Description |
|---|---|
| Core SVM Model | High-Dimensional Classification engine optimized for binary depressive sentiment prediction. |
| NLP Pipeline | Deep linguistic feature extraction powered by the spaCy transformer model (en_core_web_lg). |
| Prediction Hub | Real-Time Inference Interface built with Flask for sub-second classification feedback. |
| Security Suite | Integrated Browser-Side Integrity protocols including anti-right-click and anti-select systems. |
| Cinematic Surprise | Immersive Branding Overlay featuring animated Twitter iconography and synchronized audio. |
Note
We have engineered a Probabilistic Sentiment Manager that calibrates model weights across thousands of TF-IDF vectors to simulate human-like linguistic intuition. The visual language focuses on a "Neural Slate" aesthetic, ensuring maximum cognitive focus on the diagnostic outputs without procedural distraction.

Warning
Data Acquisition & Memory Constraints
The linguistic pipeline relies on the en_core_web_lg transformer model, which requires an initial download of approximately 800MB. Ensure a stable network connection during setup. Additionally, loading this model into memory requires at least 2GB of available RAM to prevent swapping and ensure low-latency inference.
