Major  Challenges

• How  do  we  automatically  extract  meaningful  info  from  unstructured  text,  images,  video  …

• How  do  we  structure  the  information  for  better  data  analytics?

• How  do  we  scale  to  very  Big  Data?• How  do  we  ensure  privacy  when  mining  info?

• Graph  kernels  for  network  structured  data,  ICML  2014,  NIPS  2015,  KDD  2015,  CIKM  Weighted  Theta  Functions,  NIPS 2015  

• Large  scale  optimization:  clustering, domain  adaptation,  ICML  2017…

• Explanatory  AI/ML:  Causal  and  Counterfactual  inference,  ICML  2016,  ICML  2017

• Explanatory  AI/ML:  Disentangled  representations  in  deep  nets.

• Deep  Learning  for  NLP:  char  based  RNNs.

• Differential  Privacy:    JMLR 2017,  AAAI  2017

Privacy  in  the  Age  of  Big  Data

“Two  recent  surveys  reveal  that  consumers’  concerns  about  online  privacy  are  at  an  all-­‐time  high.” June  2014

“Big  data  might  be  big  business,  but  overzealous  data  mining  can  seriously  destroy  your  brand…”

Differential  Privacy

Emerging  mathematical  definition  of  privacy

Essence: the  participation  of  any  one  individual  won’t  change  the  result  of  the  survey  in  a  noticeable  way

Consequence:  a  robust  definition  with  good  properties

Results  in  the  DataBIN Project

• Programming  framework  that  achieve  privacy  by  construction– no  need  to  trust  the  programmer

• A  Framework  for  Local  Differential  Privacy– no  need  to  trust  the  analyst

• Machine  Learning  with  Differential  Privacy
