Understanding machine learning
One of the most commonly cited examples of machine learning is an on-demand music streaming service.
When a user listens to music on Spotify, for example, machine learning algorithms learn to associate their music preferences with other listeners who share similar tastes.
This information is then used to recommend new songs, albums, or artists, with the same process occurring in other services that employ automated suggestions such as Netflix.
At the fundamental level, machine learning involves complex mathematics and coding that serve the same mechanical function that a car or computer screen does.
However, a device that is capable of machine learning can perform a function with the data available and become better at performing that function over time.
Machine learning is useful in scenarios where tasks need to be automated. Financial professionals may use it to be alerted of favorable trades, while a data security firm may use machine learning to detect malware.
Whatever the application, AI-based algorithms are programmed to learn constantly and are more than capable of acting as a substitute for a human personal assistant.
Understanding deep learning
As we noted earlier, deep learning is a subset of machine learning based on artificial neural networks.
The learning process itself is considered “deep” because of the structure of the network which is comprised of various inputs, outputs, and hidden layers.
In short, each layer consists of units that transform input data into information the next layer can utilize for a specific predictive task.
This structure means that a deep learning machine can analyze data with logic similar to that employed by a human.
In fact, the very structure of the ANN itself is inspired by the neural network of the brain, which results in a learning process that is far more sophisticated and complex than machine learning.
Deep learning is becoming increasingly prevalent thanks to advances in technology. It is used in automated driving to detect obstacles such as pedestrians and road signs.
Militaries also use it to identify objects from satellite pictures and define safe zones for troops.
Key Similarities
