Success Stories

Real-World AI Impact

AI Psychotherapy App

The Challenge

Mental health professionals needed effective tools to identify early signs of relapse and gain deeper insights from patient self-assessments, beyond traditional methods. Traditional self-reporting often misses subtle changes.

Our Solution

Mobile app and cloud platform with 13 specialized AI agents analyzing patient data across multiple dimensions:

  • Multimodal fusion (text + voice + physio signals)
  • Cross-correlation and causal-hypothesis testing
  • AI vs. self-report consistency checking
  • Clinical dashboard with mental health change alerts
90% AI ↔ User agreement
0.92 AUC performance
Deployed in: Clinics & Private Practices
Key Value: Early Relapse Detection

Technology Stack

Predictive Maintenance Deep Learning Anomaly Detection Signal Processing Edge AI (NVIDIA Jetson) Autoencoders Convolutional Networks Data Pipelines

Advanced ML for Predictive Maintenance in Wind Energy

The Challenge

A leading wind turbine maintenance startup needed an AI-driven acoustic monitoring system to achieve early fault detection (e.g., gear wear, bearing faults, delamination) long before traditional SCADA or visual inspections.

Our Solution

We developed the core machine learning engine—a robust anomaly detection framework processing multi-modal acoustic and vibrational signals (sub-Hz to 25kHz).

  • Utilized custom-trained deep learning models (autoencoders, convolutional networks) to identify subtle acoustic deviations.
  • Designed a scalable training pipeline for high-frequency data acquisition and real-time preprocessing.
  • Enabled models to automatically classify known faults and detect new anomaly patterns.
  • Ensured models are resilient to noise, drift, and environmental variation.
