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
