Your proven path to success in Machine Learning Interviews – developed by FAANG engineers. Unlock ML loops at top companies with a System Design approach.

System design is an important component of any ML interview. Being able to efficiently solve open-ended machine learning problems is a key skill that can set you apart from other engineers and increase the level of seniority at which you’re hired.

This course helps you build that skill, and goes over some of the most popularly asked interview problems at big tech companies. You’ll walk step-by-step through solving these problems, focusing in particular on how to design machine learning systems rather than just answering trivia-style questions. 

Once you’re done with the course, you’ll be able to not just ace the machine learning interview at any tech company, but impress them with your ability to think about systems at a high level. If you have a machine learning or system design interview coming up, you’ll find the course tremendously valuable.

Grokking the Machine Learning Interview

The architectural components diagram for entity linking is shown below. It consists of two paths:

1. Model generation path (training flow)
2. Model execution path (prediction flow)



> 📝 The terms *entity mention* and *recognized entity* are used interchangeably.

# Model generation path

Model generation is responsible for training models for entity linking task. Let's look at the components of this path.

## Training data generation

You will begin by gathering training data for entity linking through open-source datasets and manual labelling/linking of text. These methods will be detailed in the next lesson.

You will pass the training data to the named entity recognition (NER) model trainer and the named entity disambiguation (NED) model trainer.

## NER

NER is responsible for building a machine learning model to recognize entities, such as a person, organization, etc., for a given input text.

## NED
The disambiguation component will receive the output of the NER for linking. The disambiguation process has two phases:

1. Candidate generation

   The first phase of disambiguation is candidate generation. It finds potential matches for the entity mentions, by reducing the size of the knowledge base to a smaller subset of *candidate documents/entities*. This saves us from running the linking model on the entire knowledge base for each entity mention.

Let's go over the architectural components of the entity linking unit.
