论文地址:Learning Tree-based Deep Model for Recommender ... KDD2018 Motivation 这篇论文讨论的是推荐系统中的召回模型。在召回阶段,面对海量商品,针对用户做个性化推荐时,往往需要在效果和效率之间做权衡。以往的召回模型中,为了提高计算效率,往往采用类似矩阵分解的方式,分别计算user-vector和item-vector,然后把两...
通过离线学习item的embedding向量,然后通过积量化的方式构建索引,在线上应用的时候,实时计算user embedding,在索引中查找最近邻(比较user emb和item emb的乘积)的 K 个 item 作为推荐候选。这类方法的核心思想是将用户和商品用向量表示,用向量内积大小度量兴趣,借助向量索引实现大规模全量检索。但是这个方法不太方便去做...
Deep Learning Once you understand which settings work well, try a more accurate model, such asInception-v3orResNet-50, and see if that improves your results. Size When you deploy to edge devices such as Raspberry Pi®or FPGAs, choose a model with a low memory footprint, such as...
Tree-based Deep Match(TDM)是由阿里妈妈精准定向广告算法团队自主研发的基于深度学习上的大规模(千万级+)推荐系统算法框架。在大规模推荐系统的实践中,基于商品的协同过滤算法(Item-CF)是应用较为广泛的,而受到图像检索的启发,基于内积模型的向量检索算法也崭露头角,这些推荐算法产生了一定的效果,但因为受限于算法模...

Suite of tools for deploying and training deep learning models using the JVM. Highlights include model import for keras, tensorflow, and onnx/pytorch, a modular and tiny c++ library for running math code and a java based math library on top of the core c
Mimic Explainer (Global Surrogate) + SHAP tree Mimic Explainer is based on the idea of training global surrogate models to mimic opaque-box models. A global surrogate model is an intrinsically interpretable model that's trained to approximate the predictions of any opaque-box model as accurately ...
Hence, automatic methods are required to optimize tree species mapping. Here, we propose a deep learning-based mobile application tool for tree species classification in high-spatial-resolution RGB images. Several deep learning architectures were evaluated, including mobile networks and traditional models...
For DDN, we used our published single-input neural network (https://github.com/eguomin/regDeconProject/tree/master/DeepLearning) based on three dense blocks. Here we improved the image preprocessing steps by adding online data augmentation and percentile-based normalization. During training, the tr...
