How to Answer: What is the 'bag-of-words' algorithm?
Advice and answer examples written specifically for an Advanced Machine Learning Engineer - Python job interview.
3. What is the 'bag-of-words' algorithm?
This question shows the developer's knowledge of machine learning algorithm.
The bag of word model is used for NLP (Natural Language Processing). A given text is broken up into a set or "Bag" of words. This disregards the grammar and the word order of the text.
The frequency of occurrence of each word is then recorded. This process is used to simplify the NLP algorithms. The technical interviewer may ask this question in order to determine if you are aware of various simplification processes before asking you to demonstrate a natural language processing algorithm.
Writing an NLP algorithm entirely from scratch can take a long time so the technical interviewer may provide the following code in order for you to build the algorithm further.
