I wonder if the accuracy varies based on ethnicity. The results have been suboptimal for all the asians I tried. My 80 year old grandma showed up as 55. My 6 year old son is categorized as 20.<p>Perhaps the OP should consider asking for feedback to to correct the model.
It guessed correct for me, 40. I'm 38. I'm Indian.<p>Incorrect for a picture of my mother who's 62. It guessed 34. And the picture is of decent quality.
