Data Scientist Interview Questions
Q1: Can you explain the difference between supervised and unsupervised learning?
Supervised learning involves training a model on a labeled dataset, where the input data is paired with the correct output. The model learns to predict the output for new, unseen data. In contrast, unsupervised learning deals with unlabeled data, where the model tries to identify patterns or groupings within the dataset without prior knowledge of the outcomes.
Q2: What are some common metrics used to evaluate the performance of a machine learning model?
Common metrics include accuracy, precision, recall, F1 score, and area under the ROC curve (AUC-ROC). The choice of metric often depends on the specific problem and the cost of false positives versus false negatives.
Q3: How do you handle missing data when building a model?
I handle missing data by using various techniques such as imputation (mean, median, mode), deletion of missing values, or using algorithms that can handle missing data directly. The choice of method depends on the extent of missing data and its potential impact on the analysis.
Q4: Can you describe a project where you used a data pipeline?
