Zalo AI Challenge is an artificial intelligence contest that is always interested and awaited by the Vietnamese AI community every year. This playground is seriously invested by Zalo AI, with quality and above all, putting fairness first. After each exam season, good solutions are applied in practice, contributing to narrowing the gap between AI and Vietnamese life.
In 2021, the contest returns and challenges the teams in 3 practical topics: “5K Compliance” – Determines whether the group of people in the picture have followed the 5K rules correctly; “Hum to song” – Find the song title through a humming or whistling passage and “Legal Text Retrieval” – Search for rules in the legal document database to answer the question. Although each exam has its own measure, the ultimate goal is to solve topical and highly practical problems.
After more than a month of taking place, the Zalo AI Challenge 2021 contest has officially ended and marked impressive numbers. The contest attracted 1,016 teams with 1,234 contestants registered to participate, thereby receiving 5,051 submissions, 307 teams competing on the Leaderboard. The highest position of each question has also found a worthy owner with the most effective algorithm.

In the 5K Compliance topic, the champion belonged to the NTBN team with 0.86703 points measured by the F1 index; The Hum to Song topic found the champion as team Wano with 0.40188 points as measured by the MRR and finally the Legal text retrieval test found the champion as the 3PU team with a score of 0.64804 as measured by the F2 measure.
Zalo AI challenge has always been attractive to the AI passionate community, including students sitting on school chairs. Nguyen Nhat Hoang (22 years old), a final year student of Hanoi University of Science and Technology, won first place in the 5K Compliance exam. Hoang said that you participated in the competition from the 2020 season, but because you did not have much experience, you gave up halfway, and returned to 2021 with high determination, you won the top position of the competition.
“The topic of 5K Compliance is very practical and true to my computer vision knowledge, so I decided to choose this topic. I approach the problem by observing data, finding ways to clean and diversify After that, I will test different base models to choose the best model. Finally, select, change parameters and train. Besides, I also use cross validation to limit the model being overfit”, the young people shared.

Commenting on this year’s AI solutions of this year’s teams, Mr. Chuong Nguyen (the issue board) said: “The teams all apply very new deep learning models in 2020 – 2021. However, the prizes The main difference is solutions that focus on data processing, for example in the 5K Compliance problem is the handling of unlabeled data and soft-labeling, in the Hum to Song problem it is in the audio preprocessing and how to enrich the data hum…”.
