Biomimicry and Neural Networks

Nature or Technology?

This argument of “Nature vs Technology” has persisted for a long time now. Many are of the opinion that the advent of technology has paved a path for the destruction of nature. However, we fail to understand that they both, in fact, work hand in hand.

‘Biomimicry’ is a simple technique where the elements of Nature are studied and implemented to solve human problems.

The kingfisher’s sleek beak spurred the streamlined nose design on high-speed trains in Japan. Cockleburs inspired the hook-and-loop fastener system Velcro. And the Namibian beetle’s back inspired a water-collection plant in the desert.

Another phenomenal example could be found in ‘Neural Networks’. Neural Networks are a part of Deep learning , and are essentially used to mimic the Human Brain and solve complex data driven problems. This concept is inspired by the way the human brain works. A human brain can process huge amounts of information using data sent by human senses. The processing is done by neurons, which work on electrical signals passing through them and applying flip-flop logic, like opening and closing of the gates for signal to transmit through.

Now, what is a Neural network?

Neural networks are often used for classifying a given set of data.( A simple example could be identifying shapes.) This is done by breaking each image into a number of pixels. These pixels are then fed into the input layer of the neural network. These inputs are passed from the input layer to the hidden layer to the output layer. (Depending on the number of layers in the network.)

Initial random weight is assigned to each input. The inputs are then multiplied with their corresponding weights and their sum is further processed through the network.Furthermore, by using probability techniques, the machine is able to recognize the shape.

Deep learning, through the use of Neural Networks, has found its way into marketing, health industry, self-driving cars and also into the creative arts. An AI based system called ‘Muse net’ can generate 4-minute musical compositions with 10 different instruments, and can combine styles from country to Mozart to the Beatles.

Technology is surely a way of nature, and the future holds many more nature-driven creations for the curious minds.
