Are they Different?? Are not they the same? What is the difference? Why is the difference? Are we digging deeper in Machine Learning with Deep Learning? All the above queries will get answered below.
Similarities Between Deep Learning & Machine Learning
Knowing the difference would be very practical if we know the similarities. Practically, deep learning is just a subset of machine learning, while ML is Artificial Intelligence itself. Deep Learning technically similar to machine learning and its functions. However, its capabilities are different. We are living in a world that gets carried away with buzzwords easily.
To understand the differences, we have to understand their processes and functioning. According to Mr. Andrew Ng, the chief scientist of search engine Baidu and one of the leaders in the Google Brain Project, in an analogy which he shared with Wired Magazine.
“I think AI is kin to building a rocket ship. We need a huge engine and a lot of fuel to build the ship. If we have a large engine and a tiny amount of fuel, we will not make it to orbit, or if we have a tiny engine and a ton of fuel, we can not even lift off. To build a rocket, we need a huge engine and a lot of fuel”. The analogy means that the rocket engine is the deep learning model, and the fuel is the large amounts of data we can feed to these algorithms.
So yes, we are digging deeper into machine learning.
With machine learning models, a human needs to identify and hand-code the applied features based on the data type (as an example, pixel value, shape, orientation, etc.). A deep learning model tries to learn those features without additional human intervention.
As a large amount of data is processed and the complexity of the mathematical calculations involved in the algorithms used, deep learning systems require much more powerful hardware than simpler machine learning systems. An example of hardware used for deep learning is graphical processing units (GPUs). ML models can run on lower-end machines because it needs less computing power.
Due to the large data sets and many parameters and complicated mathematical formulas involved, a deep learning system can take a lot of time to train. ML can take as little time as a few seconds to a few hours. But deep learning can take a few hours to a few weeks.
Approach To Problem
Machine learning uses algorithms that tend to parse data in parts, and then those parts combine to come up with a result. Deep learning models look at an entire problem or scenario in one fell swoop.
Types Of Different Models
Examples To Differentiate
Giving examples to distinguish things is the best way to make a proper understanding. A popular example of a machine learning algorithm is Netflix’s recommendation system. For the service to make a decision about which new series to recommend to the user, machine learning algorithms associate the user’s preferences with other users. It would be a good example to differentiate, is like we’ve programmed the Deep Learning model to turn on a light when it recognizes the term ‘Turn On’.
At its initial stages of learning, it might turn the light on with any sentence containing those switching words. As the model is trained with deep neural networks, it will start responding with similar terms like “I can’t see” or “It’s dark” after many learning stages. A DL model can learn through its method of computing that makes it seem like it has its own brain.
