A resourceful trainer who makes DoE easy to understand

I have attended the course "Practical Design of Experiment (DoE) for Engineers and Researchers" taught by Dr. Alvin Ang at the Tertiary Infotech Academy. Dr. Ang uses a wide variety of examples to illustrate Taguchi designs, mixture designs, full and fractional factorial designs, Plackett-Burman designs, Box-Behnken designs, Response Surface Methodology, and other experimental optimization techniques. He demonstrated how Minitab can be used to generate these experimental designs, analyze the data, and generate various plots to visualize the results. Dr. Ang is a very resourceful trainer and has included many personal experiences to make the course engaging. He explains all concepts clearly and in a manner that is easy to understand. He has also demonstrated how generative artificial intelligence tools can assist in DoE. Dr. Ang is very experienced in his field of work; he has worked on Procter and Gamble's Supply Chain Redesign and has helped the Research Director of The Logistics Institute Asia Pacific to prepare a proposal for Singapore General Hospital's home delivery of medication. Furthermore, Dr. Ang has five publications on the topic of Kanban Systems and Operations Research. Overall, Dr. Ang is a strong communicator and I enjoyed being taught by him.

Insightful and knowledgeable trainer

I had the opportunity to attend Dr Alvin Ang's R Tidyverse Data Analytics and Visualization training, and I found him to be a very insightful and knowledgeable trainer. What I appreciated most was how he connected the technical concepts with practical, real-world applications. He went beyond simply teaching R and the Tidyverse tools, and shared valuable insights into how data analytics is actually applied in the industry. As someone who is relatively new to the data analytics field, I found his industry perspectives especially valuable. He gives practical perspectives on the skills, expectations, and continuous learning needed to progress in this field. He also took the time to share additional learning resources and introduce me to a social network of data scientists, giving me opportunities to continue learning even after the training has ended. Overall, I found Dr Alvin to be an engaging, practical, and supportive trainer with strong industry knowledge.

Patient Trainer Who Makes Sure We Really Understand

This is my second time joining Dr. Alvin Ang's class. I first attended last year on 16 Aug 2025. Today I signed up for the Excel Power Query and Power Pivot course. Dr. Ang is very patient. He makes sure we really understand, and he'll even invite us to a Google Meet to troubleshoot why Power Pivot or Power Query isn't working. He also shares tips to help speed up our work and make daily tasks easier.

Excellent Course for Beginners

Really enjoyed Dr Alvin Ang's Machine Learning 101 for Financial Trading course. He has a jovial and engaging teaching style that makes even complex machine learning concepts easy to understand — we were never bored! What I found especially valuable was how he clearly showed where and how machine learning fits into the different stages of an AI trading system. The conceptual materials and sample Python codes shared were also very useful for further learning and experimentation after the course. A fair note for anyone considering the course: this is not a course on profitable trading strategies. It focuses on the fundamental building blocks of data-driven systematic trading, which I think is exactly what beginners need to build a solid foundation. Highly recommended for beginners, or anyone looking to refresh their ML knowledge and understand how it is being applied to systematic trading today. Thanks, Dr Alvin, for the great insights and enjoyable learning experience!

Exceptional trainer with incredible patience

Ms. Amanda was an exceptional trainer and coach during my recent CCNA course. Throughout the session, she consistently demonstrated incredible patience, dedication, and enthusiasm for the subject matter. Rather than rushing through the agenda, she made sure to check in with the team, address every question thoroughly, and ensure that everyone fully grasped each concept before moving on to the next topic. Her engaging teaching style, practical examples, and attentive support significantly deepened my understanding of the material and gave me complete confidence in applying what I learned and also the upcoming exam.

Dr. Alvin has a very clear and structured teaching style that made complex statistical concepts easy to understand, even for someone without a strong background in the subject. He guided us through practical tools such as Excel Analysis ToolPak, covering techniques like hypothesis testing, t-tests, ANOVA, and data visualization in a very hands-on and engaging way. What stood out most was his humor, patience and willingness to ensure every learner have a good time and kept up. He created an environment where asking questions was encouraged, which really helped build my confidence in applying these skills. Thanks to his guidance, I have been able to apply what I learned to my work and continue developing my data analysis skills.

A luminary in the field of data science

Few can claim to know such a luminary in the field of data science as Dr Alvin Ang. Our correspondence has led me to realize the sheer breadth and depth of the field of data science. Only a true expert like Dr Ang could have revealed to me through his advocacy, teaching, publications, and real world experience how diverse the field truly is. From the very start I was star-struck, first by his academic achievements — a doctorate in Operations Research, a master's in Logistics and a bachelor's in Engineering, all from the world renowned Nanyang Technological University — and then by his experience in industry as well as in academia as a lecturer, trainer, consultant and analyst. He continues to impress and inspire me with his achievements. I highly recommend Dr Ang as the most reputable data scientist that I have been fortunate to know.
