WHAT DOES THAT GOTTA DO WITH THE TALK TODAY? • Two Interesting Ideas about Technology that I am interested to think about/invest/develop if I ever have the free time. • Next Generation Social Networks based on Degrees of Association which measure Inﬂuence and Reputation. • Voice Recognition on Mobile Phones and Computers. • This talk is just a sketch of how each one of these products can be created and developed. • Remember: Ideas are cheap, Execution is key.

PRODUCT 1 NEXT GENERATION WEIGHTED SOCIAL NETWORKS Friday, February 27, 2009

SOCIAL NETWORKS Social Networks are Cultural, Generational & Geographical. Source: Oxyweb, Nov 2008 Friday, February 27, 2009

From Friendster to Facebook Static Proﬁle Dynamic Proﬁle: News Feed, Groups, Events Friday, February 27, 2009

Linkedin connects people professionally but does not distinguish the inﬂuencers or the connectors Friday, February 27, 2009

THE PROPERTIES OF A SOCIAL GRAPH Six Degrees of Self-Organizing Nature • • Seperation: Everyone is of Networks: scale free connected to each other and the ability of identify within six degrees of generic hubs and experiment. connectors in a network. Friday, February 27, 2009

A SOCIAL GRAPH THOUGHT EXPERIMENT Friday, February 27, 2009

In the online world, each connection is characterized by a 1(Connected) or 0 (Not Connected) Friday, February 27, 2009

The Current Social Network is unable to measure Degrees of Association, i.e. how well you know that person. Friday, February 27, 2009

TRY THIS NEW IDEA 9 9 Rule 1: Each user assigns a degree of association 7 5 value (1-10) on how well you know the other 7 person. Do it for multiple 8 users. Score this based on the average of each pair scores. Friday, February 27, 2009

10 5 10 9 10 • Rule 2: Fit a statistical 2 distribution on all your associations. • Rule 3: Calibrate the weights between each pair of 7.5 users based on the social 9.5 6 Friday, February 27, 2009

A WEIGHTED SOCIAL NETWORK Friday, February 27, 2009

With a weighted social network, you can search for best path to connect to someone within a network and also ﬁnd the inﬂuencers and hubs. Friday, February 27, 2009

PRODUCT 2 AN OPEN SOURCE VOICE RECOGNITION PROJECT Friday, February 27, 2009

PROBLEM • Can you build a voice recognition app which shows the name of the person and his/her number when you say his/her name? • Current Developments: iPhone - Google App (1.5 mins), Nokia (2-3 mins), Blackberry (2-3 mins). • The challenge is to reduce the time to recall the name and number within 30s. Friday, February 27, 2009

WHY IS IT SO DIFFICULT TO SAY “COMPUTER, ...”? • Getting the Universal Voice Training Set is extremely difﬁcult: • Different Accents • Different Languages • Different Intonation • Different Pitch Friday, February 27, 2009

HERE’S A SKETCH: Fundamental Assumption: What if we conﬁne voice recognition of a gadget • such as a mobile phone to the user alone and speciﬁcally target the apps adjusted to him? An Open Source Voice Recognition Project (GPL) that consists of: • Repository to store training sets of users for research purposes. • An API built on three core layers: Training Data API, Recognition API and • Application API. Build a few apps and get the developers/users community to join the fray • Training Data API Recognition API Application API Friday, February 27, 2009

WHAT TYPE OF APPLICATION • Suggestions for Basic Voice Recognition Apps: • Voice Recognition Lock • Voice Recognition Shutdown • Voice Recognition Search (1-3 words) to locate where you are. • Slowly evolve the complexity and let your imagination run wild. Friday, February 27, 2009
