Every morning I start my day by checking the weather report. I simply ask Siri to tell me the weather report of the day. Our lives are surrounded by technology, but have you ever thought about how Google Assistant or Siri can understand exactly what you need?
It is through a combination of AI and deep learning. Just like the human brain comprises neurons, deep learning networks are made up of artificial neurons.
Let us explore the working, structure, and applications of deep learning networks in this deep learning tutorial that I have curated for beginners like you.
Deep learning is a subset of machine learning (ML) that mimics the human brain's neuron network. It uses artificial neural networks to process data just like the human brain.
Deep learning tutorial models can recognize complex details in texts, pictures, sounds, and other forms of data. It uses this information to produce accurate predictions and insights.
Deep learning can learn and improve based on user behavior over time. I have used many deep learning methods to automate tasks that generally require human intelligence, like transcribing a sound to text or describing an image.
To understand the basics of deep learning, you must understand the components of a neural network. The parts of a deep learning network are the following:
Neural networks form the core of deep learning concepts. These networks form the functional units of a deep learning system. They are known to mimic the behavior of the human brain for solving complex data-driven problems. Input data is processed through several layers of artificial neurons stacked together to produce the desired output.
If you want to understand the workings of neural networks, enrolling in a deep learning online course can be beneficial.
Here are the components of an artificial neuron.
Let us understand the different parts of the deep learning diagram given above.
You possibly cannot have a holistic deep learning tutorial without learning about its types. Here are some of the different types of deep learning neural networks:
This artificial neural network ensures that the nodes do not form a cycle. All the perceptrons in this neural network are organized within the layers i.e., the input layer takes in the input and the output layer generates the output.
Every perceptron contained in a single layer is associated with every node in the subsequent layer. All the nodes in the network are connected, however, there are no connections between the nodes present in the same layer.
In this network, there are no back loops. The backpropagation algorithm is used for updating weight values, to minimize prediction error. Let’s say, you want to perform image recognition, this is the neural network that will be used.
Some other applications are as follows:
It is a multilayer neural network biologically inspired by the animal visual cortex. CNN has hidden convolutional layers forming the ConvNets.
As a deep learning network, early layers recognize the minute features of the image (such as borders, edges, shapes, textures, etc.) and the later layers recombine those features into higher-level input attributes. The deeper the network, the more sophisticated the pattern searching.
It is used for performing tasks such as image analysis, language processing, and various complex image classifications.
Some applications of CNN are:
In a basic deep learning architecture, there is a fixed input size which acts as a blockage in cases where the input size varies. The RNN model works very well with a sequence of input data.
These networks have the power to remember what it has learned in the past and apply it for future predictions. Every time the hidden internal state of RNN reads the data sequence, it gets updated. This internal hidden state is fed back to the model. This neural network produces an output at every time stamp.
Some applications of RNN are:
Restricted Boltzmann machines are a two-layered neural network, consisting of only the input and the hidden layers. Every node in the hidden layer of this network is connected to each node in a visible layer.
In traditional Boltzmann Machine networks, the nodes within the input and hidden layers are also connected. However, in a Restricted Boltzmann Machine, nodes within a layer aren't connected because of computational complexity.
Some applications of the Restricted Boltzmann Machine are:
This artificial neural network comprises three layers: input, hidden, and out layers. The input layer is first encoded into the hidden layer with a proper encoding function. Number of nodes in the input layer are much more than the number of nodes in the hidden layer.
The hidden layer comprises the compressed representation of the original input data. The input layer is reconstructed by the output layer using a decoder function.
The difference between the input and output layers is calculated using an error function during the training phase. The weights are also adjusted to minimize the error.
Some applications are:

Deep learning systems are made up of neural networks of two to three layers. A neural network attempts to model the behavior of the human brain by learning from large data sets.
Here are some uses of deep learning in today’s world:
Fraud is a recurring problem in the digital world. According to a report by the Federal Trade Commission, 2.4 million fraud cases have been reported. To prevent fraud, many companies use deep learning to detect anomalies in user transactions.
Deep learning is deployed to collect data from various sources, such as credit card purchase patterns, device location, etc, for creating unique user profiles. This helps in identifying any fraudulent behavior.
The gap between machines and humans continues to blur as virtual assistance becomes a part of our everyday lives. These tools are driven by AI, but display a mix of machine learning, AI, and deep learning techniques to process commands.
Google’s Google Assistant and Apple’s Siri are two prominent examples of virtual assistants that can operate across speakers, laptops, TVs, and other devices.
The goal of deep learning systems is to mimic how the human mind detects patterns from digested information. It is the ideal way to train vision-based AI programs.
A deep learning system uses mathematical calculations for automatically processing various aspects of image data and gradually develops a combined understanding of the image.
Using this technology, robots can read messages and derive meaning from them. However, the process can somewhat be oversimplified, not able to account for how words combine to change the intent or meaning behind a sentence.
With deep learning, natural language processors are able to identify more complex patterns in sentences to provide a more accurate interpretation. One of the best examples of this is Grammarly. It uses deep learning along with grammatical patterns and roles for identifying writing errors and gauging the tonality.
When driving, external factors are the key things to keep in mind. Even though we might be far from fully autonomous vehicles, deep learning plays a crucial role in making this technology come to action.
Let's say I am driving an autonomous vehicle. Once the vehicle knows where I want to go, it predicts the obstacles in the path and creates a safe path for me to reach my destination.
Apart from the applications discussed in this deep learning tutorial, there are several other uses of it.
Deep learning networks have a wide range of applications as you’ve come to know from this detailed deep learning tutorial. Artificial neural networks in deep learning systems sure can perform complex tasks with minimal assistance from the programmer.
The field of AI is growing at an exponential rate, however, there are not many qualified candidates to work in the field. Taking up a professional deep learning course can help you learn about the fundamentals of AI and this concept as a whole.

Deep learning, a subset of machine learning, uses multi-layered neural networks, for stimulating the complex reasoning power of the human brain.
The deep learning interface will not happen without training. Deep learning models are trained with large labeled data sets.
There are several advantages of deep learning. It is used for performing complex tasks such as image recognition, speech recognition, feature extraction, etc. It can ingest and process unstructured data.
Machine learning models generally perform well with comparatively small data sets. Whereas, deep learning models need large data to understand and perform properly.
Some popularly used deep learning frameworks are TensorFlow, PyTorch, DGL, PyTorch Geometric, etc.
The three main components of a DL model are:
One of the main disadvantages of deep learning is the requirement of large amounts of labeled training data to learn from effectively. The unavailability of proper data can be an issue. Another issue in these networks is the overfitting of input data.
Deep learning models are used in image processing, signal processing, computer vision, automated driving, etc.
