PART G – Data Science Interview Questions

  • What are the differences between overfitting and underfitting?

    In statistics and machine learning, one of the most common tasks is to fit a model to a set of training data, so as to be able to make reliable predictions on general untrained data.

    In overfitting, a statistical model describes random error or noise instead of the underlying relationship. Overfitting occurs when a model is excessively complex, such as having too many parameters relative to the number of observations. A model that has been overfit has poor predictive performance, as it overreacts to minor fluctuations in the training data.

    Underfitting occurs when a statistical model or machine learning algorithm cannot capture the underlying trend of the data. Underfitting would occur, for example, when fitting a linear model to non-linear data. Such a model too would have poor predictive performance.

  • Python or R – Which one would you prefer for text analytics?

    We will prefer Python because of the following reasons:
    Python would be the best option because it has Pandas library that provides easy to use data structures and high-performance data analysis tools.

    R is more suitable for machine learning than just text analysis.

    Python performs faster for all types of text analytics.

  • What does P-value signify about the statistical data?

    P-value is used to determine the significance of results after a hypothesis test in statistics. P-value helps the readers to draw conclusions and is always between 0 and 1.

    • P- Value > 0.05 denotes weak evidence against the null hypothesis which means the null hypothesis cannot be rejected.
    • P-value <= 0.05 denotes strong evidence against the null hypothesis which means the null hypothesis can be rejected.
    • P-value=0.05is the marginal value indicating it is possible to go either way.
  • Can you write the formula to calculate R-square?

    R-Square can be calculated using the below formula :
    1 - (Residual Sum of Squares/ Total Sum of Squares)

  • What is the difference between type I vs. type II error?

    A type I error occurs when the null hypothesis is true, but is rejected. A type II error occurs when the null hypothesis is false, but erroneously fails to be rejected.”

  • Explain the 80/20 rule, and tell me about its importance in model validation.

    People usually tend to start with a 80-20% split (80% training set – 20% test set) and split the training set once more into a 80-20% ratio to create the validation set. It is used to verify the model performance on unseen data.

  • What is bias?

    Bias is an error introduced in your model because of the oversimplification of a machine learning algorithm." It can lead to underfitting.

  • What is Ensemble Learning?

    The ensemble is a method of combining a diverse set of learners together to improvise on the stability and predictive power of the model. Two types of Ensemble learning methods are:

    Bagging
    Bagging method helps you to implement similar learners on small sample populations. It helps you to make nearer predictions.

    Boosting
    Boosting is an iterative method which allows you to adjust the weight of an observation depends upon the last classification. Boosting decreases the bias error and helps you to build strong predictive models.

  • How is kNN different from kmeans clustering?

    Don’t get mislead by ‘k’ in their names. You should know that the fundamental difference between both these algorithms is, kmeans is unsupervised in nature and kNN is supervised in nature. kmeans is a clustering algorithm. kNN is a classification (or regression) algorithm.

    kmeans algorithm partitions a data set into clusters such that a cluster formed is homogeneous and the points in each cluster are close to each other. The algorithm tries to maintain enough separability between these clusters. Due to unsupervised nature, the clusters have no labels.

    kNN algorithm tries to classify an unlabeled observation based on its k (can be any number ) surrounding neighbors. It is also known as lazy learner because it involves minimal training of model. Hence, it doesn’t use training data to make generalization on unseen data set.

  • What is the difference between covariance and correlation?

    Correlation is the standardized form of covariance.
    Covariance's are difficult to compare. For example: if we calculate the covariance's of salary ($) and age (years), we’ll get different covariance's which can’t be compared because of having unequal scales. To combat such situation, we calculate correlation to get a value between -1 and 1, irrespective of their respective scale.

  • When does regularization becomes necessary in Machine Learning?

    Regularization becomes necessary when the model begins to ovefit / underfit. This technique introduces a cost term for bringing in more features with the objective function. Hence, it tries to push the coefficients for many variables to zero and hence reduce cost term. This helps to reduce model complexity so that the model can become better at predicting (generalizing).

  • Please enumerate the various steps involved in an analytics project.

    Following are the numerous steps involved in an analytics project:

    • Understanding the business problem
    • Exploring the data and familiarizing with the same
    • Preparing the data for modeling by means of detecting outlier values, transforming variables, treating missing values, et cetera
    • Running the model and analyzing the result for making appropriate changes or modifications to the model (an iterative step that repeats until the best possible outcome is gained)
    • Validating the model using a new dataset
    • Implementing the model and tracking the result for analyzing the performance of the same
  • Please explain Gradient Descent.

    The degree of change in the output of a function relating to the changes made to the inputs is known as a gradient. It measures the change in all weights with respect to the change in error. A gradient can also be comprehended as the slope of a function. Gradient Descent refers to escalating down to the bottom of a valley. Simply, consider this something as opposed to climbing up a hill. It is a minimization algorithm meant for minimizing a given activation function.

  • What is ROC curve?

    It stands for Receiver Operating Characteristic. It is basically a plot between a true positive rate and a false positive rate, and it helps us to find out the right tradeoff between the true positive rate and the false positive rate for different probability thresholds of the predicted values. So, the closer the curve to the upper left corner, the better the model is. In other words, whichever curve has greater area under it that would be the better model.

  • What is IQR ( Interquartile Range ) and Usage ?

    It is difference between 75th and 25th percentiles, or between upper and lower quartiles, It is also called Misspread data or Middle 50%.
    Mainly to find outliers in data, if the observations that fall below Q1 - 1.5 IQR or above Q3 + 1.5 IQR those are considered as outliers. Formula for IQR = Q3-Q1

  • What is Hypothesis Testing ?

    Hypothesis testing is a statistical method that is used in making statistical decisions using experimental data. Hypothesis Testing is basically an assumption that we make about the population parameter.

  • What type of metrics in Regression ?

    RMSE – Root Mean square error

    MSE – Mean square error

    MAE – Mean absolute Error

    R2 Square

  • What type of metrics in Classification ?

    Confusion Matrix = ((TP + FN)/(FP + TN))
    Accuracy score = (TP+TN)/TP+TN+FP+FN
    Recall , True positive rate, – ( TP/TP+FN)
    Precision – (TP/TP+TN)
    F1score = 2(precision*recall)/precision + recall

  • What is precision?

    The ration of predicted positive against the actual positive.
    It is the most commonly used error metric is n classification mechanism.
    The range is from 0 to 1, where 1 represents 100%.

  • What is recall?

    The ratio of the true positive rate against the actual positive rate.
    The range is again from 0 to 1

  • What is the difference between a dictionary and a set?

    Dictionary has key value pair
    set does not have key value pairs
    set has only unique elements

  • What are the various types of analysis on type of data?

    Univariate – 1 variable
    Bivariate – 2 variables
    Multivariate – more than 2 variables

  • What is the difference between qualitative & quantitative ?

    Quantitative method analyses the data based on numbers. Qualitative method analyses the data by attributes.

  • What are residuals in a regression task?

    The difference between the predicted value and the actual value is called the residual.

  • What is Back Propagation and Explain it’s Working.

    Back propagation is a training algorithm used for multilayer neural network. In this method, we move the error from an end of the network to all weights inside the network and thus allowing efficient computation of the gradient.

    It has the following steps:

    • Forward Propagation of Training Data
