The field of machine learning is quite a hot topic. We know that this type of artificial intelligence (AI) provides computers with the ability to learn without being explicitly programmed. For people like me who need it in simpler terms, machine learning deals with systems that can learn from past data and experience to improve performance of a particular task. Machine learning already is touching our daily lives, both personally and professionally, more than anyone could've imagined. For example, a home's lawn sprinkler system can be trained to tell the difference between squirrels and cats, and to turn on when cats walk on the grass in order to shoo them away.
