What is Deep Learning - Applications | Advantages | Challenges

Table of Contents [show]

Deep learning is the brain of machine learning. Instead of telling the computer exactly what to do, we use artificial neural networks (or deep neural networks). These networks are like computer brains inspired by how our brains work. They're good at learning tricky stuff from various examples without us having to spell everything out. 

Moreover, it aids in finding the best patterns and connections. Nowadays, it's getting popular because our computers got a lot faster and we have tons of data to play with.

Why is Deep Learning Crucial?

Here are some factors that make deep learning an important component.

• Deep learning helps computers savvy, trying to learn and think just like humans.
• It allows Voice-activated television remotes.
• It helps catch hackers online by finding fraud and recognizing faces without us doing anything.
• It's not just for now; it will be a big deal in automatic facial recognition.
• Computer wizards make some files called deep learning models. These files teach machines to be good at tasks using a collection of rules.
• Businesses use these models to look at data and guess things in different situations. 

Now, we will learn about the applications of it. It will be beneficial further when you read each concept. 

Applications of Deep Learning

The following section will help you to know about its applications. Just read and get knowledge.
 

      Computer Vision

Deep learning gives eyes to computers through computer vision. With deep learning, machines can spot and make sense of things in pictures and videos. 

• Object Detection and Recognition: Helps machines find and understand things in pictures and videos, like self-driving cars or surveillance systems.
• Image Classification: Sorts images into groups into an animal or a building. They are used in medical imaging and quality control.
• Image Segmentation: Divides images into parts. In addition, it helps to identify specific details within pictures.    
  
  Natural Language Processing (NLP)

NLP teaches computers to talk and understand our language using deep learning. With deep learning, machines can not only comprehend what we say but also create new sentences.

• Automatic Text Generation: Teaches computers to create new text, like making summaries or essays without human help.
• Language Translation: Translates text from one language to another. However, it makes it possible to talk with people who speak different languages.
• Sentiment Analysis: Figures out if the text is positive, negative, or neutral. Its requirements are customer service, social media, and understanding opinions in politics.
• Speech Recognition: Helps computers understand spoken words. Additionally, it is beneficial for turning speech into text, voice searches, and controlling devices by talking.
  
  
  Reinforcement Learning

When you hear about reinforcement learning, just picture your computer as an in-training. It assists in learning to win by doing things in the easiest way possible.
 

• Game Playing: Teaches computers to be good at games. It can also beat humans in challenging ones like Go, Chess, and Atari games.
• Robotics: Trains robots to do complicated tasks like grabbing things, moving around, and manipulating objects.
• Control Systems: It helps control big and complicated systems like power grids and traffic. Moreover, it makes supply chains work better.

Now, we will understand the challenges that come with it.

Challenges in Deep Learning

• Big Data Challenge: It needs a lot of examples to become savvy, which means we need tons of data to learn from.
• Computational Resources: Training these models needs unique equipment called GPUs and TPUs.
• Time-Consuming: It Depends on the computer's speed. As a result, training deep learning models can be delayed. Sometimes, it takes a long time, even days or months.
• Interpretability: Deep learning models do amazing things, but we don't always understand how.
• Overfitting: If the model keeps studying the same stuff repeatedly, it becomes good at one thing but struggles with new things. We call that overfitting.

Here, we’ve learned about some challenges. The following section will discuss the pros and cons of it.

Merits And Demerits

Now, we will elaborate on the advantages and disadvantages of the same. It will help you to know more in detail. First, we will discuss its merits and then demerits.

Advantages of Deep Learning

• High Accuracy: It recognizes pictures and understands what we're saying.
• Automated feature engineering: If your computer can figure out what's important in a picture or text, deep learning does. There is no need for humans to tell it what to focus on.
• Scalability: Deep learning models can handle massive bundles of information.
• Flexibility: Deep learning can work with various items, such as text pictures, and even understand what people say.
• Getting Better All the Time: Deep learning models are improving their performance regularly.

After learning the pros, It's time to understand the demerits of it.

Disadvantages of Deep Learning
 

• High computational needs: This requires massive data and computational resources to become beneficial.
• Requires large amounts of labeled data: It teaches your computer by putting labels on everything. However, it wants a LOT of labeled examples, which can take a long time and money.
• Interpretability: Sometimes, we don’t get how it makes decisions.
• Overfitting: Sometimes, it studies too hard on the same things and blunders with new stuff.
• Black-box nature: Deep learning models can do amazing things, but we're still determining how.

Here, we have shown you all the challenges, pros, and cons. Now, we will discuss the primary concept - differentiate between deep learning and machine learning.
