我们提出了一种生成性深度学习框架,用于将包含平方根速度函数(SRVF)的大型函数数据集合与其模板进行联合多重比对。我们提出的框架是完全无监督的,能够与预定义的模板对齐,并在实现对齐的同时从数据中联合预测最优模板。我们的网络被构建为一个生成性编解码器体系结构,包括能够产生翘曲函数的分布空间的完全连接层。我们通过在合成数据和磁共振成像(MRI)数据的扩散曲线上验证我们的框架的强度。
We present SrvfNet, a generative deep learning framework for the joint multiple alignment of large collections of functional data comprising square-root velocity functions (SRVF) to their templates. Our proposed framework is fully unsupervised and is capable of aligning to a predefined template as well as jointly predicting an optimal template from data while simultaneously achieving alignment. Our network is constructed as a generative encoder-decoder architecture comprising fully-connected layers capable of producing a distribution space of the warping functions. We demonstrate the strength of our framework by validating it on synthetic data as well as diffusion profiles from magnetic resonance imaging (MRI) data.
