  • Objective: Optimize inventory management and reduce supply chain costs by predicting demand for products.
  • Techniques: Time series forecasting, demand prediction models (ARIMA, Prophet, machine learning).
  • Data Needed: Inventory data, product sales history, supply chain logistics data.
  • Outcome: Minimize stockouts, reduce overstocking, and improve overall supply chain efficiency.

9. Image Recognition for Defect Detection in Manufacturing

  • Objective: Develop a computer vision system to automatically detect product defects in a production line.
  • Techniques: Convolutional Neural Networks (CNNs), image classification, object detection.
  • Data Needed: Image data of products (defective and non-defective).
  • Outcome: Improve quality control by automating defect detection, reducing human error, and improving production efficiency.

10. Customer Segmentation

  • Objective: Segment customers based on purchasing behavior or demographics to tailor marketing efforts.
  • Techniques: K-means clustering, hierarchical clustering, DBSCAN, principal component analysis (PCA).
  • Data Needed: Customer data (age, income, purchase history, geographic location).
  • Outcome: Create targeted marketing campaigns, improve product recommendations, and increase customer satisfaction.

11. Anomaly Detection in IoT (Internet of Things) Systems

  • Objective: Identify abnormal behavior in IoT devices, such as temperature sensors, or detect faults in machinery.
  • Techniques: Isolation forests, autoencoders, statistical models, and clustering techniques.
  • Data Needed: Real-time sensor data (e.g., temperature, pressure, motion).
  • Outcome: Prevent system failures, reduce maintenance costs, and improve system reliability.

12. Social Media Analytics for Brand Monitoring

  • Objective: Track brand mentions across social media to analyze the effectiveness of marketing campaigns.
  • Techniques: Text mining, sentiment analysis, trend analysis, topic modeling (LDA).
  • Data Needed: Social media posts, hashtags, user comments, and mentions.
  • Outcome: Assess brand health, identify influential trends, and measure the impact of campaigns.
