Top 50 Machine Learning Interview Questions and Answers.

1) What is Machine learning?

Ans - Machine learning is a branch of computer science which deals with system programming in order to
automatically learn and improve with experience. For example: Robots are programmed so that they
can perform the task based on data they gather from sensors. It automatically learns programs from
data.

2) Mention the difference between Data Mining and Machine learning?

Ans - Machine learning relates with
the study, design and development of the algorithms that give
computers the capability to learn without being explicitly programmed. While, data mining can be
defined as the process in which the unstructured data tries to extract knowledge or unknown
interesting patterns. During this process machine, learning algorithms are used.

3) What is ‘Over-fitting’ in Machine learning?

Ans - In machine learning, when a statistical model describes random error or noise instead of underlying relationship ‘over-fitting’ occurs. When a model is excessively complex, over-fitting is normally observed, because of having too many parameters with respect to the number of training data types. The model exhibits poor performance which has been over-fit.
