Deep learning is related to machine learning based on algorithms inspired by the brain's neural networks. Though it sounds almost like science fiction, it is an integral part of the rise in artificial intelligence (AI). Machine learning uses data reprocessing driven by algorithms, but deep learning strives to mimic the human brain by clustering data to produce startlingly accurate predictions.

Examples of deep learning

Deep learning is generating a lot of conversation about the future of machine learning. Technology is rapidly evolving, generating both fear and excitement. While most people understand machine learning and AI, deep learning is the "new kid on the block" in tech circles and generates both anxiety and excitement.

Deep learning is also known as neural organized learning and happens when artificial neural networks learn from large volumes of data. Deep learning algorithms perform tasks repeatedly, tweaking them each time to improve the outcome. The algorithms depend on vast amounts of data to drive "learning."

Current estimates predict that 1.145 trillion MB of data is produced every day, and it is this staggering amount of data production that makes deep learning possible [1]. The vast increase in data creation is the driving force behind the rise in deep learning capabilities. Though deep learning can sound mysterious, the truth is that most of us are already using deep learning processes in our everyday lives.

Below are a few of the tasks supported by deep learning:

Virtual assistants

Do you use Alexa, Cortana, or Siri? Popular virtual assistants use deep learning to understand the language and terminology humans use when interacting with them. As a result, they become more adept at providing the information requested.

Driverless vehicles

Autonomous vehicles are already on our roadways. Deep learning algorithms help determine whether the object on the road is a paper sack, another vehicle, or a child and react accordingly.

Chatbots

Chatbots have gained popularity and appear on many websites used every day. Chatbots powered by deep learning can increasingly respond intelligently to an ever-increasing number of questions. The deeper the data pool from which deep learning occurs, the more rapidly deep learning can produce the desired results.

Facial recognition

Facial recognition plays an essential role in everything from tagging people on social media to crucial security measures. Deep learning allows algorithms to function accurately despite cosmetic changes such as hairstyles, beards, or poor lighting.

Medical science

The human genome consists of approximately three billion DNA base pairs of chromosomes. Machine learning is helping scientists, and medical professionals create personalized medicines, diagnose tumors, and is undergoing research and utilization for other pharmaceutical and medical purposes.

Careers in deep learning

As in all manner of machine learning and artificial intelligence, careers in deep learning are growing exponentially. Deep learning offers organizations and enterprises systems to create rapid developments in complex explanatory issues.

Data Engineers specialize in deep learning and develop the computational strategies required by researchers to expand the boundaries of deep learning. Data Engineers often work in specific specialties with a blend of aptitudes across various research ventures.

Typical jobs in deep learning

  • Physics

  • Calculus

  • Dynamic programming

  • Applied mathematics

  • Natural language processing

  • Neural network architecture

Becoming proficient in deep learning involves both technical and non-technical expertise. Since its inception, artificial intelligence and machine learning have seen explosive growth. The advent of deep learning has sped up the evolution of artificial intelligence. Those exploring a career in deep learning will find themselves poised to explore the latest frontier in machine learning.

Necessary education

Deep learning is a subset of machine learning, so understanding the basics of machine learning is a good foundation on which to build. Though many Deep Learning Engineers have PhDs, it is possible to enter the field with a bachelor's degree and relevant experience. Proficiency in coding and problem solving are the base skills necessary to explore deep learning.
