高级算法开发(Senior Algorithm Developer)
Current项目一:通过线性回归,GBDT,LSTM等建立算法模型预测店铺销售额,通过逻辑回归,Softmax, SVM,XGBoost等建立算法模型,识别店铺销售额欺瞒行为。项目二: 通过关联规则算法,对商场销售数据进行分析,对商品的关联关系进行分析。数据量较大,通过在Spark集群上运行Scala编写的关联规则实现。项目三:建立推荐引擎系统,对app用户进行推荐商品/活动,涉及到ItemCF,UserCF,FM等算法。Project1: Applying Linear Regression, GBDT, LSTM and etc to establish algorithm modeling, in predicting the shop sales amount; Applying Logic Regression, SVM, XGBoost, Softmax to classify the cheating behavior when shop reporting its sales amount (in order to lower the rent).Project 2: Build the recommend system from 0 to 1, and to recommend campain and products to users according to their respective features, algorithm applied are ItemCF, UserCF, FM and etc.Project 3: Image processing and recognition using OpenCV, mainly on size measuring of manufacturing products through images, OCR to recognize charactor from PDF and images and etc.
