Q. What is an Eigen Vector?
Ans. 

Eigen vector is a vector that does not change its direction when a linear transformation is applied to it.

  • Eigen vectors are used in linear algebra to understand the behavior of linear transformations.

  • They represent directions along which a linear transformation has a simple effect, such as scaling.

  • Eigen vectors are associated with eigenvalues, which represent the scaling factor of the eigenvector.

  • For example, in a...

Q. What are the parametric types of machine learning?
Ans. 

Parametric types of machine learning are algorithms that make assumptions about the functional form of the relationship between inputs and outputs.

  • Parametric models have a fixed number of parameters that are learned from the training data.

  • Examples include linear regression, logistic regression, and linear SVM.

  • They are often simpler and faster to train compared to non-parametric models.

Q. How do you calculate precision and recall for an n x n confusion matrix?
Ans. 

Precision and recall can be calculated using values from a confusion matrix.

  • Precision = TP / (TP + FP)

  • Recall = TP / (TP + FN)

  • Where TP = True Positive, FP = False Positive, FN = False Negative

  • For an n x n confusion matrix, sum the values in each row and column to get TP, FP, and FN for each class

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.
