01 Multi-Modal Price Match Guarantee Efficient-Net, NF-Net,Bert Kaggle : Shopee-Price Match Guarantee Teammate : Zoey Xu zoeyxu@aliyun.com Duration : 2021.5 Competition : Team Work (Leader)
Do you scan online retailers in search of the best deals?In this competition, we applied our machine learning skills to build a model that predicts which items are the same products. Captained my teammates to conduct data exploratory analysis, feature processing, building baseline (TFIDF+ResNet18+Result Splicing) and models optimization iteration. Responsible for parameters adjustment of Finetune and TFIDF for BERT model, and NFNet training for CV, the similarity algorithm selection, models’ fusion and prediction results splicing, ranked top 11 among over 3000 teams.
ABSTRACT Kaggle : Shopee-Price Match Guarantee Description : Retail companies use a variety of methods to assure customers that their products are the cheapest. Among them is product matching, which allows a company to offer products at rates that are competitive to the same product sold by another retailer. In this competition, well applied our machine learning skills to build a model that predicts which items are the same products. The applications go far beyond Shopee or other retailers. We contributions to product matching could support more accurate product categorization and uncover marketplace spam. Evaluation : F1 score = 2 × (Precision × Recall) / (Precision + Recall)

COMPARISON Comparison to Top 1% Kernel in the Competition
CONCLUSION Limitations & Future works
Future Works : After comparing with the winning kernel of the competition. The most serious deficiency of our kernel is post-processing and vote in prediction. According to the prediction results of the optimal LB score model in the early stage, we found that there are a large number of unmatched samples in the statistical results, that is, the matching results only match themselves, so we can reduce the matching standard (increase the matching distance threshold or reduce the similarity threshold) Comparison: Baseline ( TFIDF + ResNet18 + Result Splicing) : LB Score: 0.653 Top 80% My Solution (EfficientNet-B3 + EfficientNet-B5 + Nfnet-l0 + TFIDF + BERT + (Multi-Modal)) : LB Score: 0.734 Top 11% Top Solution (Nfnet-l0 + swin-small + EfficientNet-B0 + BERT + Indonesian-BERT + Multlingual-v1 + TFIDF) : LB Score:0.746 Top 1%

2.1 Urban Big data Features Prediction System Using the API of Amap to collect POI and geographic data of Shanghai, combined with the popularity and housing prices crawled of the Lianjia agent as basic dataset, adopted pix2pixHD model to establish forecast model for second-hand housing distribution map. 2.2 Reform the Ancient Façade Used Style Transfer technology to explore the possible applications of deep CNN in architecture design, studied the façade style of the Parthenon Temple and successfully applied the ancient Greek architectural style to modern vehicles 2.3 Landscape Generation with GAN We collected 120 landscape planes on pinterest and ArchiDaily. By training pix2pixHD model, the automatic generation of landscape planes is realized.
ABSTRACT 2.1 Urban Big data Features Prediction System
Description : Using the API of Amap to collect POI and geographic data of Shanghai, combined with the popularity and housing prices crawled of the Lianjia agent as basic dataset, adopted pix2pixHD model to establish forecast model for secondhand housing distribution map.
DATASETS POI Data + Graph Data
POI (Points of Interest) Data (From Amap.api)
Index : Index of second-hand houses in Shanghai.(Total 6000) location: Longitude and latitude of each sample. Hospnums: Number of hospitals within 1000m. Subnumbs: Number of hospitals within 800m.
Edubumbs: Number of hospitals within 500m. Total_Price: The price of the whole house. Unit_Price: Unit price per square meter. Follow_Count: Number of followers on lianjia.com.
Househeat: Househeat(θ) = α / log2(β） α = Number of followers on lianjia.com. β = Duration on sale. *Numbs are Based on the service radius of each POI point. Graphs Data (From Baidu Map &ArcGis)

AI + Architecture Exhibition in Designsociety Tutor : Fei Qu fqu@szu.edu.cn Duration : 2021.12 Location : Shenzhen China Competition : Team Work (Leader)
Design society, china’s first dedicated cultural design hub, has opened its doors to the public in shenzhen. the new institution is housed within the sea world culture and arts center (SWCAC), a building designed by japanese architect fumihiko maki, and houses a new V&A gallery. Shekou fishing Market will be demolished by the end of November 2020. Invited by Design society and Huawei cloud , we will build an art installation in the sea world culture and arts center (SWCAC) to continue Shekou people's memory of Shekou fishing Market. This art installation combining AI and architecture will be displayed in the museum. We will place the camera in the market and use Yolo_v3 algorithm carries out human shape detection in real time. Through stepping motors and art devices in the museum, we conveys the same sense of crowding to exhibitors as in Shekou market. This sense of crowding will also be preserved in the form of data.
