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.

  Q1. You are given a train data set having 1000 columns and 1 million rows. The data set is based on a classification problem. Your manager has asked you to reduce the dimension of this data so that model computation time can be reduced. Your machine has memory constraints. What would you do? (You are free to make practical assumptions.) Answer: Processing a high dimensional data on a limited memory machine is a strenuous task, your interviewer would be fully aware of that. Following are the methods you can use to tackle such situation: Since we have lower RAM, we should close all other applications in our machine, including the web browser, so that most of the memory can be put to use. We can randomly sample the data set. This means, we can create a smaller data set, let’s say, having 1000 variables and 300000 rows and do the computations. To reduce dimensionality, we can separate the numerical and categorical variables and remove the correlated variables. For numerical variable...

What is Data Preprocessing?

  Data preprocessing  is a step in the data mining and data analysis process that takes raw data and transforms it into a format that can be understood and analyzed by computers and machine learning. When we talk about  data , we usually think of some  large datasets  with some rows and columns. While that is a likely scenario, it is not always the case — data could be in so many different forms:  Structured Tables, Images, Audio files, Videos , etc. Machines don’t understand text, image, or video data as it is, they understand 1s and 0s. Real-world data also contains noises, missing values, etc. which cannot be directly used for ML models. Hence,  data preprocessing  is required for cleaning the data and making it suitable for an ML model which increases the accuracy and efficiency of the model. It involves the following steps: Getting the Dataset Importing Libraries Importing Dataset Data Quality Assessment: i) Finding and Processing Missing/Inc...
