Insights and Solution Approaches for the 2020 Tencent Advertising Algorithm Competition
The 2020 Tencent Advertising Algorithm Competition challenges participants to predict user gender and age from 90‑day click logs, and the champion shares data understanding, feature engineering techniques such as one‑hot, TF‑IDF, Word2Vec, and modeling strategies including GBDT and RNN/LSTM/GRU to guide competitors.
In the preliminary round of the 2020 Tencent Advertising Algorithm Competition, participants must predict user gender and age using 90‑day ad click logs and basic ad attributes.
The champion of the 2019 competition, a data‑science enthusiast and author, introduces himself and explains the dataset, emphasizing the need to understand each variable, such as creative_id and the ad material generation process.
He outlines several feature‑engineering methods: a high‑dimensional one‑hot encoding (which can be discarded due to size), TF‑IDF applied to sequences of creative_id/ad_id treated as documents, and Word2Vec embeddings generated from click sequences, noting the limitations of simple aggregation.
For modeling, traditional GBDT models can be used, but sequence‑modeling techniques like RNN, LSTM, or GRU are recommended to capture temporal patterns in user behavior.
The speaker encourages participants to stay calm, apply these insights, and wishes them success in advancing past the preliminary round.
