How could Transfer Learning be used in Artificial Intelligence?

Machine Learning and Artificial Intelligence are being used in many industries and their usage keeps growing with an increase in the performance of the systems respectively. Some of the interesting applications of machine learning are in Self-driving cars and pharmaceutical industries. There are a lot of latest interesting applications being created every day with the use of AI and machine learning. There is a subset of Artificial Intelligence called Deep Learning where there are complex units of neurons that would perform the computations when needed. One thing to note is that when performing these computations, the models would optimize their weights and biases in the process of classifying a certain set of objects in images in the case of image classification tasks.
