24. FACT THEY’RE DELICIOUS (JOKING!)
25. WHAT IS A RED PANDA? • THE ‘ORIGINAL’ PANDA • NOT RELATED TO THE GIANT PANDA Not a bear Not a raccoon
26. WHAT IS A RED PANDA? • ORDER: CARNIVORA; SUPERFAMILY: MUSTELOIDEA • DISTANTLY RELATED TO SKUNKS, RACCOONS AND WEASELS • ONLY SPECIES IN THEIR FAMILY: AILURIDAE • AILURUS FULGENS - MEANS “SHINING OR FIRE-COLORED CAT”
27. RED PANDA DISTRIBUTION • SHADED AREAS ARE PROTECTED LAND
28. HABITAT AND ADAPTATIONS • SMALL BIOLOGICAL NICHE • BAMBOO UNDERSTORIES • 2,200-4,800 M ELEVATION • STEEP SLOPES • 10-24 DEGREES CELSIUS • ADAPTATIONS TO HARSH CLIMATE • DENSE FUR • THICK TAIL • FURRED FEET
29. CARNIVORE – YET A BAMBOO SPECIALIST • SPECIALIZE ON YOUNG, TENDER SHOOTS AND LEAVES • FRUIT, INSECTS, SMALL MAMMALS & BIRDS
30. NUTRITIONAL ADAPTATIONS • SIMPLE, CARNIVORE DIGESTIVE SYSTEM • ADAPTATIONS FOR HIGHLY FIBROUS DIET • LARGE DENTITION • LOW METABOLIC RATE • FASTER PASSAGE RATE • LARGE HOME RANGE http://snuzzy.com
31. REPRODUCTIVE ADAPTATIONS • SLOW TO SEXUALLY MATURE ~18 MO • EXCEPTIONALLY LONG GESTATION – 2X SIMILAR CARNIVORES • AVERAGE: 134 DAYS (RANGE: 98-158 D) • SMALL LITER SIZE (2-4 CUBS)
32. CONSERVATION STATUS • IUCN REDLIST: ENDANGERED • 50% POPULATION DECLINE • CITES: APPENDIX I • WILD POPULATION: <10,000 • CAPTIVE POPULATION: ~860
33. THREATS TO WILD POPS • DEFORESTATION • HABITAT FRAGMENTATION • GRAZING LIVESTOCK • DISEASE • POACHING • CLIMATE CHANGE Worldwildlife.org wwf.panda.org Peter Oxford/TRAFFIC
34. THREATS TO POPS UNDER HUMAN CARE • ~50% OF CUBS DIE WITHIN 1ST YEAR • 20% STILLBORN OR DEATH • NEONATAL PNEUMONIA • POOR MATERNAL CARE • MATERNAL CANNIBALISM
35. RESEARCH ON RED PANDAS • RED PANDAS ARE TRULY A UNIQUE SPECIES • LACK OF BASIC BIOLOGICAL KNOWLEDGE HINDERS CONSERVATION EFFORTS • RESEARCH NEEDED ON: • REPRODUCTION (BEHAVIOR AND PHYSIOLOGY) • MATERNAL-CUB RELATIONS • NEONATAL HEALTH AND CRITICAL CARE
36. NESTBOX CAMERAS • 50% CUBS DIE IN FIRST YR • CUBS SPEND 3-4 MO IN NESTBOX • CRITICAL DEVELOPMENTAL PERIOD – WE KNOW LITTLE ABOUT • SURVEILLANCE CAMERAS
37. BIRTH MONITORING
38. MOTHER-CUB INTERACTIONS
39. RESEARCH ON RED PANDAS
40. RESEARCH ON RED PANDAS
41. RESEARCH ON RED PANDAS
42. USE OF TECHNOLOGY – NESTBOX CAMERAS
43. CHALLENGE SPECIFIC CHALLENGES: LONG VIDEOS: ~6-12 HOURS LARGE FILES: >1GB INTERNATIONAL USERS
44. SOLUTION NEED TO APPROACH THIS PROBLEM LIKE A PROFESSIONAL SOFTWARE ENGINEER
46. BREAK IT DOWN
47. STEP 1 NEED TO GET THE FILES UPLOADED • PAPERCLIP • JQUERY-FILE-UPLOAD
48. GOTCHA
49. STEP 2 IDENTIFY THE PANDAS ON VIDEO
50. FIND HELP JOSHUA SZMAJDA
51. MACHINE LEARNING NEURAL NETWORK
52. MACHINE LEARNING ANALYZING VIDEO IS NOT AN OPTION
53. MACHINE LEARNING PICTURES ARE EASIER
54. STEP 3 PICTURES ARE EASIER
55. CONVERT THE VIDEO TO IMAGES
56. CONVERSION FFMPEG
57. GOTCHA 30 * 60 * 60 * 6 ~650,000
58. STEP 4 TENSORFLOW -- INCEPTION NETWORK
66. GOTCHA DIFFERENT VIDEO FORMAT
67. RETRAIN
68. RETRAIN
69. STEP 5 ANALYZE THE PICTURES
70. RED PANDA > 0.6 == “YES” ["NO", "NO", "YES", "YES", "YES"...]
71. GOTCHA FALSE POSITIVES/NEGATIVES
72. RESULTS? ACCURATE COST EFFECTIVE
73. ARE PROJECTS LIKE THIS INTERESTING TO YOU?
