Some improved solutions:

• [a] It can be further improved by manaully aligned these images which are mis-algined in LFW
• [b] It can be further improved by doing mutiple-crop, e.g. 25 crops for per image
• [c] It can be further improved by ensemble different models
• [d] It can be further improved by adding metric learning method for similarity caculation
