AIAP® Assessment

AI Singapore’s AI Apprenticeship Programme (AIAP)® was launched in 2018 to groom local Singaporean AI talent and enhance their career with AI-related skills. In the first 2 months, apprentices undergo a self-directed deep-skilling phase that is supported by AISG’s AI engineers, data scientists and computational resources. This is followed by a 7-month on-the-job training where AI apprentices execute real-world projects with the 100 Experiments team or our in-house engineering teams (see below for the different tracks). Since its launch, there have been 11 batches of apprentices who have embarked on this award-winning programme. 

Before becoming an AI apprentice, he/she has to pass our recruitment process. The recruitment process consists of two stages and both stages provide a platform for applicants to showcase their technical competencies, knowledge and ability to solve machine learning challenges. Basic knowledge in statistics, data analytics, machine learning and software engineering are essential to excel in the programme.

The two stages of our recruitment process are: technical assessment and interview. 

The technical assessment requires applicants to perform exploratory data analysis (part 1) and build an end-to-end machine learning pipeline (part 2) on an unseen dataset. In part 1, applicants are expected to extract the dataset from a database before performing an exploratory data analysis of the dataset (EDA). In the EDA, applicants should develop a good understanding of the dataset by analyzing each feature individually as well as their interactions. Applicants should also form hypotheses about the dataset and verify them during the EDA. A good submission involves presenting these findings in a logical and well-thought-out process with insights.

In part 2, multiple machine learning models have to be developed and evaluated based on the given task. In the development of these models, applicants are required to document their design decisions in data pre-processing and reasoning to support their choice of models. In addition, models should be evaluated in a meaningful manner with an evaluation metric that is appropriate for the task at hand. When tackling a problem using different approaches, applicants may have to be creative to find a common evaluation metric to ensure consistency across comparisons.

As part of the submission process, applicants will be required to package their work for review. Submissions should include an iPython notebook (.ipynb file format), Python (.py file format) and bash (.sh file format) scripts. Other files required to recreate the development environment should also be included. Reproducibility is an extremely important tenet in machine learning and the ability to reproduce an applicant’s results is a key assessment point. Submissions should also demonstrate an understanding of software engineering fundamentals and all code submitted should incorporate proper coding conventions while being readable and easily understood.

We do expect applicants to demonstrate a reasonable understanding of key concepts in statistics, data analysis and machine learning. While heuristics, checklists and flow charts for standard practices may be useful, AIAP applicants are expected to understand the rationale behind these tools and be able to decide (and justify) how to apply these ideas in new situations.

As the development of machine learning models is an iterative process with a considerable amount of experimentation, it is recommended that applicants take a principled approach to experimentation and appropriately justify any design considerations.

The next stage of the recruitment process consists of a technical interview and a group case study exercise. At the start of the technical interview, applicants are to present their submissions. While the content of the presentation is free-form, we recommend applicants make the best use of their time by highlighting areas of their work that are critical and distinctive.  

In the group case study exercise, applicants are allowed to work with other like-minded individuals on an undisclosed case study. The team is given time to formulate, document and present their solution. Besides reaffirming the applicants’ technical competencies, the second stage of the recruitment process is also designed to identify applicants who possess the ability to problem-solve and demonstrate themselves as team players.

We are heartened to see the improvement in the quality of applicants in each batch’s application and we hope that the pointers above will be helpful to current and prospective applicants. We would like to wish all applicants the very best of luck in their assessment and we look forward to welcoming you as AI apprentices.
