Technology: Human brain vs AI brain




To think is a very complex process no matter how small or idiotic or great the thought is. Acting on the thought is further complex because it becomes a selection of choices. Artificial Intelligent programs are supposed to do both. Thinking in AI world means processing the information while acting becomes executing subsequent program or to produce a real world action.

Baby Vs The Robot

If you have spent your hours and days trying to build an AI bot you would have by now definitely appreciated human brain for its beauty of functioning. Human brain is one of the best creations of the nature. The comparison between AI processing and human brain comes when the real world problems cant be solved with just mathematical equations and rather needs a logical perspective. There is no mathematical equation for LOVE!! or maybe there is 2×idiot=love ;). Keeping the joke apart even the brain of a newly born knows who the mother is whereas AI codes needs tremendous amount of energy and logic for facial recognotion. The story does not end here the brain knowing the mother acts accordingly when hungry or want something but again for AI code it comes down to more learning. The point here is if we go by all the things that even an average person gets the training for during his/her life then its very time consuming and difficult to train AI program for all those things. A simple example would be as below, see the two versions of writing a word,
Version 1 : |_O\/£
Version 2 : LOVE


While in an instant you would have read both as "love" the AI code would not have done the same for the 1st version unless specifically designed for it because almost all letters are special characters. Although you had a better context and you knew whatever you are reading is a word but the AI code might not have that.

What is the actual difference?

Lets look at some facts about human brain and the computational powers that AI codes rely upon.

1. Memory or Memory 1,0,1

Human brain: Genetically programmed to create, store and process relations between two entities based on associative memory/context
AI: Maintains and processes relations based on occurances/provided data.

Example -

Consider a situation where a person greets you stating he/she knows you from blabla.
Now you try to remember but cant or maybe after some time you do. But have you ever wondered why the other person remembers you but you cant? Apart from lets say having a weak memory its because you did not associated the context or memory to that person back then. But for AI once a record gets in its store in this case  the person does exist otherwise not. There is no grey area in AI even if its inserted programmatically it cant be processed as an actual information so ambiguity is a no no for AI.


2. Understanding vs Facts

Human brain: Learning is based on assumptions, facts, experience
AI: Learning is based on data

Example-

Consider that an intelligent program and a person is given a book of Harry Potter to read. So unless you explicitly mention that Magic is not real the program will process everything as real but an average person would based on experience and assumptions only will mark it as a work of fiction.

The main thing here is in real world there is many false/complex data which may cause an unintended machine learning and its too tedious a task to get the correct data with proper context and leaving no choice but to rely on a judgment call which might cause a disaster for coding.

3. Machine Learning Or a School?

Human brain: Does not requires millions of data to understand something
AI: Requires similar data to understand a pattern

Example-

Remember when way back in your school you haveto learn ABCD..Z? Well your teacher did not had to draw thousands of A's in different shapes ad formats to make you understand the same. They just had to tell you what A is and how it basically lools like. After knowing that you can understand the letter A even if it was written in different shapes/fonts in a word. E.g.


Artificial Intelligence has to undergo machine learning process and NLP to grasp this. In fact they are few of the major challenges while building an AI systems.


To summarize,
There are so many differences between a human brain and an AI processing that they cant be covered in a single post. But for starters these are some ofthe major differences. I am waiting for a day where an AI system can capture the images from a camera in goggles, converts them to electric impulses and transmit to neurons so that they can act as an eye for a blind person. This will be the day I will actually start fearing AI. You think AI can achieve this?

Technology: How to create a website with .com for almost free

Hello World!!
If you dont have a website of your own now then you are loosing your future value at this very moment. Period. When it comes to creating a website you might think its very complex, time consuming, costly and not of worth. 

All of these are not completely true. With todays technology you can create a website, Within 2 minutes with default domainFor free with default domainFor few bucks with custom domainWhich can earn you fair amount of side income if dedicatedly worked onWhich can be used to promote or showcase yourself
All of us want have our own house and aim to get one. Its great to have such a physical asset but what about the digital world? We all simply ignore the online space where almost half of the world spends atleast few minutes in a day. So it becomes very important to have your website and make your presence in the digital world. A website is your personal asset in the online space.
There are very few sites which actually tell  you how to get your own websit…

Travel : Guide - Top 5 ultimate travel destinations in world

Hello travellers!!

We all have different preferences when it comes to traveling to the tourist places around the world. Some love the crowd, some solitude while some love a good adventure to feel the rush and some travel just to taste the local foods. Having said this, there are certainly some places which are well above our individual preferences and simply shouldn't be missed. In this post I intend to give you the list of 5 such places. Now these majestic destinations may involve a bunch of places nearby or just one place.


If you are wondering why only 5 and why not more than that, then you are right. There obviously are still way more awesome places that one should not miss traveling to but for now lets look at these places first as I will post about other places soon.

1. Kerala, India India, a country known for many good things, one of which is undoubtedly presence of thousands unique cultures within it. This ultimately makes India a great place to visit for an enthusiastic t…

Will evolution of Artificial Intelligence (AI) overtake humans??

Ever seen a movie "I Robot"? If so, then you may have wondered "huh! so evolution is meant for any piece of crap that exists" or such similar thought. My view is YES, it is meant for everything including the cap of your pen to the piece of code written somewhere on earth. They all undergo a change maybe for betterment or for worse. One such evolution is over its way and is progressing rapidly I might add, the evolution of AI. When we say evolution we generally think its the development for something better. But it is not a necessity that it is for better of human beings only.  I would put evolution in 3 phases future, present and past. The future becomes present, the present becomes past and the past becomes the trigger.


For the sake of making it easy for me to tell the evolution of AI from my viewpoint, I will tell you folks inline with these 3 phases. Don't worry I am not going to increase your boredom by giving you the information on AI enhancements till no…
