Neural Networks vs. Deep Learning: How Are They Different?
Artificial intelligence has become an integral part of our daily lives in today’s technology-driven world. Although some people use neural networks and deep learning interchangeably, their advancements, features, and applications vary.
So what are neural networks and deep learning models, and how do they differ?
What Are Neural Networks?
Neural networks, also known as neural nets, are modeled after the human brain. They analyze complex data, complete mathematical operations, look for patterns, and use the information gathered to make predictions and classifications. And just like the brain, AI neural networks have a basic functional unit known as the neuron. These neurons, also called nodes, transfer information within the network.
A basic neural network has interconnected nodes in the input, hidden, and output layers. The input layer processes and analyzes information before sending it to the next layer.
The hidden layer receives data from the input layer or other hidden layers. Then, the hidden layer further processes and analyzes the data by applying a set of mathematical operations to transform and extract relevant features from the input data.
It is the output layer that delivers the final information using the extracted features. This layer may have one or more nodes, depending on the data collection type. For binary classification—a yes/no problem—the output will have one node presenting a 1 or 0 result.
There are different types of AI neural networks.
1. FeedForward Neural Network
Feedforward neural networks, mostly used for facial recognition, transfer information in one direction. This means every node in one layer is linked to every node in the next layer, with information flowing unidirectionally until it reaches the output node. This is one of the simplest types of neural networks.
2. Recurrent Neural Network
This form of neural network aids theoretical learning. Recurrent neural networks are used for sequential data, like natural language and audio. They are also used fortext-to-speech applications for Androidand iPhones. And unlike feedforward neural networks that process information in one direction, recurrent neural networks use data from the procession neuron and send it back into the network.
This return option is critical for times when the system releases wrong predictions. Recurrent neural networks can attempt to find the reason for incorrect outcomes and adjust accordingly.
3. Convolutional Neural Network
Traditional neural networks have been designed to process fixed-size inputs, butconvolutional neural networks(CNNs) can process data of varying dimensions. CNNs are ideal for classifying visual data likeimages and videos of different resolutions and aspect ratios. They are also very useful for image recognition applications.
4. Deconvolutional Neural Network
This neural network is also known as a transposed convolutional neural network. It is the opposite of a convolutional network.
In a convolutional neural network, input images are processed through convolutional layers to extract important features. This output is then processed through a series of connected layers, which carry out classification—assigning a name or label to an input image based on its features. This is useful for object identification and image segmentation.
However, in a deconvolutional neural network, the feature map that was formerly an output becomes the input. This feature map is a three-dimensional array of values and is unspooled to form the original image with an increased spatial resolution.
5. Modular Neural Network
This neural network combines interconnected modules, each performing a specific subtask. Each module in a modular network consists of a neural network primed to tackle a subtask like speech recognition or language translation.
Modular neural networks are adaptable and useful for handling input with widely varying data.
What Is Deep Learning?
Deep learning, a subcategory of machine learning, involves training neural networks to automatically learn and evolve independently without being programmed to do so.
Is deep learning artificial intelligence? Yes. It is the driving force behind many AI applications and automation services, helping users carry out tasks with little human intervention.ChatGPT is one of those AI applications with several practical uses.
There are many hidden layers between the input and output layers of deep learning. This allows the network to perform extremely complex operations and continually learn as the data representations pass through the layers.
Deep learning has been applied to image recognition, speech recognition, video synthesis, and drug discoveries. In addition, it has been applied to complex creations, like self-driving cars, which use deep learning algorithms to identify obstacles and perfectly navigate around them.
You must feed large amounts of labeled data into the network to train a deep-learning model. This is when backpropagation occurs: adjusting the weights and biases of the network’s neurons until it can accurately predict the output for new input data.
Neural Networks vs. Deep Learning: Differences Explained
Neural networks and deep learning models are subsets of machine learning. However, they differ in various ways.
Neural networks are usually made up of an input, hidden, and output layer. Meanwhile, deep learning models comprise several layers of neural networks.
Though deep learning models incorporate neural networks, they remain a concept different from neural networks. Applications of neural networks include pattern recognition, face identification, machine translation, and sequence recognition.
Meanwhile, you’re able to use deep learning networks for customer relationship management, speech and language processing, image restoration, drug discovery, and more.
Extraction of Features
Neural networks require human intervention, as engineers must manually determine the hierarchy of features. However, deep learning models can automatically determine the hierarchy of features using labeled datasets and unstructured raw data.
Performance
Neural networks take less time to train, but feature lower accuracy when compared to deep learning; deep learning is more complex. Also, neural networks are known to interpret tasks poorly despite fast completion.
Computation
Deep learning is a complex neural network that can classify and interpret raw data with little human intervention but requires more computational resources. Neural networks are a simpler subset of machine learning that can be trained using smaller datasets with fewer computational resources, but their ability to process complex data is limited.
Neural Networks Is Not the Same as Deep Learning
Though used interchangeably, neural and deep learning networks are different. They have different methods of training and degrees of accuracy. Nonetheless, deep learning models are more advanced and produce results with higher accuracy, as they can learn independently with little human interference.
