Train your dragons! by Shilpa Karkera

  1. 1. Training Your Dragons!
  2. 2. WHY? WHO? HOW? ASH LEFT HIS CHARIZARD HERE TO TRAIN ;-)
  3. 3. About Me ▶ Shilpa Karkera, CEO & Founder of Myraa Technologies ▶ Blockchain Specialist in Trade Finance | Virtual Reality with HR | Deep Learning Architect ▶ Runs a passionate team of GOHLCIs (Group of High Learning Curve Individuals) ▶ We’ve built Classifiers, Recommendation Bots, Financial Parsers used by over million users. Solving global industrial challenges in India, UK, Singapore, we created a self-revenue generated ecosystem.
  4. 4. WHAT WE TEACH THE DRAGON TODAY? AIM & FIRE MOVING OBJECTS
  5. 5. AIM & FIRE ▶ AIM VALUE FUNCTION ▶ Detection algorithm over object identification ▶ Improvisation of positional vector with Value Function ▶ V = r(t) + w*r(t+1) + w*w*r(t+2) + …. ▶ AIM & FIRE VALUE FUNCTION ▶ Detection and action trigger on threshold ▶ Value of a state-action pair ▶ Measuring the optimal policy, after executing s(t)  times V( s(t) ) = r(t) + w*V^ ( s(t) ) Q( s(t), a(t) ) = r(t) + w*max Q( s(t+1), a) a
  6. 6. WHAT THE DRAGON NEEDS TO IMPROVING ON? FIRING WITH ACCURACY OVER THE RIGHT OBJECTS
  7. 7. Computer Vision DRAGON LEARNS TO AIM • RGB extraction • Positional Vectors • Noise Elimination Image Extraction • Segmentation • Convolutional Neural network Deep Net Training • Labelling • Model Averaging • Bounding Box Regression Context Modelling
  8. 8. How ? (Training) ➢ http://www.myraatechnologies.com/DB/flowchart-parser.html Code Contributions - Lahari Meruva
  9. 9. How ? (Prediction) ➢ http://www.myraatechnologies.com/DB/flowchart-parser.html Code Contributions - Lahari Meruva
  10. 10. Classification TRAINING THE DRAGON BETWEEN RIGHT AND WRONG OBJECTS 1 Data Preparation 2 Vectorizer 3 Feature Extraction 4 Multinomial NaiveBayes
  11. 11. How ? ➢ http://www.myraatechnologies.com/DB/multiclass_clf.html Code Contributions - Avinash Goje
  12. 12. Dragon learns to classify Right Target Objects ➢ http://www.myraatechnologies.com/DB/multiclass_clf.html Code Contributions - Avinash Goje
  13. 13. Learns about moving objects, improves to learn about pseudo random trajectories, recalculates precision of aim & fires Meanwhile…. The Dragon
  14. 14. HOW? BASIC MACHINE LEARNING TO REINFORCEMENT LEARNING
  15. 15. Reinforcement Learning ACTOR CRITIC ALGORITHM
  16. 16. Dragon’s on Self-training Mode Now!
  17. 17. WHAT NEXT?? EVOLUTION OF NEW TASKS & DECISIONS
  18. 18. Being a good Dragon! HOPEFULLY!
