Deep Learning using Convolutional LSTM estimates Biological Age from Physical Activity

Abstract: Human age estimation is an important and difficult challenge. Different biomarkers and numerous approaches have been studied for biological age estimation, each with its advantages and limitations. In this work, we investigate whether physical activity can be exploited for biological age estimation for adult humans. We introduce an approach based on deep convolutional long short term memory (ConvLSTM) to predict biological age, using human physical activity as recorded by a wearable device. We also demonstrate… Show more

“…Deep neural networks are natural tools for learning non-trivial and highly non-linear representations of the input data. Convolutional and recurrent networks have been used for the analysis of intraday physical activity data streams from wearable devices and predictive modeling of health outcomes [ 23 ] including biological age [ 17 , 24 ]. Often such models demonstrate a moderate improvement in accuracy at a price of a decreased transferability across datasets with different baseline feature levels.…”

“…Simultaneously, it can be used to screen out hub genes related to cancer tissue proteins (Liu et al, 2009). The expression level of hub genes can be analyzed by deep learning (Khan et al, 2001;Rahman and Adjeroh, 2019;Zeng et al, 2019;Mallik et al, 2020). This analysis can achieve good results at the genetic level.…”

“…2, and the difference between LSTM models and CLSTM models is precisely the presence of a convolutional block of layers before the LSTM block. This approach follows previous works [27], [28] that demonstrated good classification results; again, we remark that the goal of our article is to assess the scaling generalization aspect, which was not addressed at these works, instead of an architecture evaluation. Our training set is composed of different channel temporal sequences for each observed pixel, and our assumption is that convolutional layers help to identify curve patterns in the input temporal sequences, and LSTM layers help to identify the temporal dependence of these patterns for each crop type.…”
