This page is about the skill Machine Learning, which is one of more than 40 technical skills you can assess on Alooba. The Machine Learning skill is mainly about understanding the algorithms employed by Data Scientists to explore a dataset and make specific predictions. It involves the paradigms of Regression, Classification and Clustering as the main applications of Machine Learning algorithms. Participants will need to answer questions regarding the inner workings of Machine Learning algorithms, explain in detail how they work and compare them. Moreover participants should be fluent in the use of metrics to assess the performance of algorithms and metrics that are suitable to assess Regression, Classification and Clustering algorithms. Participants will need to know the relative strengths and weaknesses of various models, and how to apply them to solve a variety of business problems.
The Machine Learning skill assesses knowledge of topics like AutoML, Bagging, Bias, Boosting, Classification, Clustering, Cost Functions, Data Splitting, Dimensionality Reduction, Distance Matrix, Ensemble Methods, Fitting Algortithms, Gradient Boosting, Homoscedasticity, Imputation, kNN, Logistic Regression, Model Training, Optimization, Random Forest, Recommender Systems, Ridge Regression & Unsupervised Algorithms.
Machine Learning is a commonly assessed skill for roles such as Data Scientist, Machine Learning Engineer, Data Science Manager & Head of Data Science.
A critical part of running an ethical hiring process that’s fair and meritocratic is having objective measures of someone’s skills. Why does ethical hiring matter? Simple - it helps you hire the best person for the job.
Robert Half reported that the cost of a bad hire is on average 15-21% of the employee’s salary.
What was the most common reason for mis-hires? A lack of the right technical skills. This a true hiring own-goal, as it’s so easily preventable through a valid, thorough skills assessment.
