Here are the results of a similar 2016 poll:Top Algorithms and Methods Used by data Scientists
See also a very interesting Kaggle survey The State of data Science & Machine Learning in 2017, which also included a section on algorithms.
Kaggle survey asked: What data science methods are used at work? and the top answers were
- Logistic Regression
- Decision Trees
- Random Forests
- Neural Networks
- Bayesian Techniques
- Ensemble Methods
- Gradient Boosted Machines
