INTRODUCTION

Hello Friends!

Welcome to the Cognitive Era! 

"Where data flows, cognition will follow"

In this blog you will learn how a cognitive system reacts to a human user and what are the uses of these systems.

WHAT IS COGNITIVE COMPUTING?

Cognitive Computing is the simulation of a human thought process

in a computerized model. Cognitive Computing involve self

learning systems that use data mining, natural language processing

to mimic the way a human brain thinks.

QUALITIES OF A COGNITIVE SYSTEM

1. Adaptive:They must learn as information changes and as goals and requirements evolve.They must resolve ambiguity and unpredictability. 
2. Interactive:They must interact well with users so that the users can define their needs of comfort.They must also interact with other processors, devices and Cloud devices.
3. Iterative:They must aid in defining a problem by asking questions or additional source of input if the question is incomplete.
4. Contextual:They must understand, identify and extract contextual elements such as meaning,syntax,time,location,appropriate domain,user's profile and regulations.

WHAT IS WATSON?

Watson is an IBM supercomputer that combines artificial

intelligence(AI) and sophisticated analytical software for

optimal performance as a "question answering machine".This

machine is named after the founder of IBM-

Thomas.J.Watson


WHAT ARE THE FUNDAMENTAL

FUNCTIONS OF WATSON?

1. Engagement:The cognitive systems like Watson change
   
   the way humans and systems interact.In this case
   
   cognitive systems play a role of an assistant except that it
   
   doesn't get tired and can consume vast amount of
   
   structured and unstructured data.It can
   
   reconcile ambiguous and self contradictory data and
   
   learn.
2. 
   Decision:These systems have the capabilities to make
   
   decisions.The decisions are purely based on the
   
   evidences and facts provided and continually evolve as
   
   new information is provided.Currently these systems act
   
   as advisors and only suggest a set of best options to the
   
   human users and ultimately the humans make the
   
   decisions.
3.  Discovery:These systems can also discover things
   
   which even the most brilliant human beings could not
   
   do.Discoveries include finding insights,connections and
   
   vast amount of data around the world.With increasing
   
   amount of data, it is a need for the system to exploit more
   
   effectively on the information than humans could do
   
   on their own.
   
   HOW DOES WATSON DO IT?

      Watson first needs to learn a new subject before it can answer questions about  it.

           FIRST WATSON LEARNS THE SUBJECT

·        All related materials are loaded into Watson, such as Word documents, PDFs and web pages

·        Questions and answers pairs are added to train Watson on the subject

·             Watson is automatically updated as new information is  published

     
THEN WATSON ANSWERS THE QUESTION

·        Watson searches millions of documents to find thousands of possible answers

·        Collects evidence and uses a scoring algorithm to rate the quality of this evidence

·        Ranks all possible answers based on the score of its supporting evidence

WATSON'S SPORT SKILLS

    Watson's deep learning, natural language and vision 

capabilities are powering Watson Golf Pro from Spare 5. The

cognitive app is a personal caddy that amateur players can

consult while at the driving range or on the course. It's been

trained with a corpus of knowledge from contracted golf

professionals on mechanics and drills. By "seeing" a golfer's

swing, the app can provide feedback for improving that swing.

    In the US open, IBM has always demonstrated their

technology chops.This time it is Watson that will be doing the

job.Watson will help the commentators in their facts and

knowledge as it would give the analytics of how well the

player has played before and what could be the chances of him

winning this match.

WATSON'S HEALTHCARE FACILITIES

1.    Analyzes the patients medical record.

    Watson for Oncology has an advanced ability to analyze the

meaning and context of structured and unstructured data in

clinical notes and reports, easily assimilating key patient

information written in plain English that may be critical to

selecting a treatment pathway.

     2.Identifies potential evidence based treatment options

    By combining attributes from the patient’s file with clinical

expertise, external research, and data, Watson for Oncology

identifies potential treatment plans for a patient.

3.Find and provides supporting evidence

   Watson ranks identified treatment options and provides links to

supporting evidence for each option to help oncologists as

they consider treatment options for their patient.
