Head First Deep Learning!

 Hello and welcome back to the CosmoTechno : The Universe Of Technology!

In today's blog we are going to understand what Deep Learning is........

Nowadays, Deep Learning is one of the best hot and emerging technology, where lots of research is going on. If you are a newbie to this technology then this blog is right place for you to understand what is it! And if you already aware about Deep Learning, then also you will get some better insights. So what are we waiting for let's get started.

Deep Learning is one of the most important subpart of Machine Learning which is again the subpart of Artificial Intelligence.


AI-ML-DL

Deep Learning technology is inspired by structure of human brain which is also called as Artificial Neural Network.

Structure of Neural Network is almost similar to the Neural Networks present in human brain. Let's try to get some better intuition about the this!


Neurons

Above image depicts a single neuron in human brain. If we try to relate a single node of our artificial neural network to this neuron we will get following:

1. Dendrites will be Input Layer of the node.
2. Nucleus and Cell Body will be Hidden Layer of the node.
3. Axon Terminal will be Output Layer of the node.

Neural-Network
This image depicts single Hidden Layered Neural network. In Neural Networks, initial layer is Input layer of the network, last layer is the Output layer of the network and layers in between input and output layer are Hidden layers. 
There are only one input layer and one output layer is present in the neural network, but there can be any number of hidden layers which completely depends upon the dataset you are using.
Some examples of the Neural Networks:
1. Simple Neural Network
2. Complex Neural Network (CNN)
3. Recurrent Neural Network (RNN)

If we look back to the history you will understand that Deep Learning is actually a very old technology. This technology wasn't much efficient that time due to lack of data available that time. But today we have huge amount of data and also we have good storage capacity and that's the reason behind "Why Deep Learning is Taking Off!"

Now let's have a look on various applications of Deep Learning:
1. Image classification is one of the famous application of Deep Learning. Very basic example of this application will be Cat Vs Non-Cat image classification.
2. Self Driving car is another most important real application of Deep Learning.
3. Along with these, Deep learning is playing significant role in healthcare system.

Apart from above there are lots of things needs to be understood about Deep Learning. I hope this blog have helped you to get some good insights about Deep Learning, in next blog you will get into the depth of working of Neural Network which will help you to try your own projects, so go ahead and   SUBSCRIBE to the newsletter get your hands dirty with Deep Learning.

What's the difference between Artificial Intelligence and Robotics

          What's the difference between      Artificial Intelligence and Robotics?                     Is Artificial Intelligence part of Robotics? OR vice versa? Are these terms same or different?   These kind of questions pop up when you listen about AI and Robotics, but don't worry you will get answer of these question after reading this blog so stay tuned! Artificial Intelligence and Robotics are actually two different fields. However, people often get them mixed up. But before getting into the depth of their difference, let's first understand what these terms are: Artificial Intelligence : Artificial Intelligence, etymologically means creating an intelligence (i.e. learning, understanding, etc. ) artificially. Whereas, technically Artificial Intelligence is an approach to make a computer, a robot, or a product to think how smart human think. Artificial Intelligenc...

Let's Get Into Machine Learning

     Hello and welcome back to the CosmoTechno - Dive Deep Into The Cosmos Of Technology! So get ready for diving deep into the cosmos of Machine Learning today. You might have been heard about this buzzword everywhere, but not really sure about what is it. Hold On! you don't have to worry about this as this blog will help you to get a valuable insight of Machine Learning. Before starting with any discussion let's have a look at the technical term of Machine Learning, Arthur Samuel says, "Machine Learning is field of study that gives computers the ability to learn without being explicitly programmed." If I rephrase the above definition it will be something like, feeding lots of experience to the machine so that it will come up with a strategy to solve a particular problem. Here experience is in the form of data which can be a text, images, videos, etc. On the basis of this data we provide there are four types of Machine Learning:        ...

Hello Deep Learning World!

Hello and welcome back to CosmoTechno! As blog title suggest, today you would be going to get a significant intuition of Deep Learning. In this blog you will be understanding how to perform Hello World project in Deep Learning. Recognizing Handwritten Digits is one of the most famous as well as beginner friendly project of Deep Learning. If your completely newbie or you are not familiar with basic concept of Deep Learning then I will recommend  you to read the previous blog on deep learning. In this blog I am going to perform Handwritten digit recognition using Convolutional Neural Network(CNN) which we will implement with the help of Tensorflow, Keras libraries. Before getting into hands on coding part we will try to understand how CNN works. CNN is a one of the significant Neural Network which is commonly used in Deep Learning. In image recognition or classification task CNN divide each image into very small boxes and try to get some meaningful patterns from the same and store ...
