چکیده
Recently, the topic of indoor outdoor detection (IOD) has seen its popularity increase, as IOD models can be leveraged to augment performance numerous Internet Things and other applications. aims at distinguishing in an efficient manner whether a user resides or environment, by inspecting cellular phone sensor recordings. Legacy attempt determine user’s environment comparing measurements some threshold values. However, we also observe our experiments, such exhibit limited scalability, their accuracy poor. Machine learning (ML)-based aim removing this limitation, utilizing large volume train ML algorithms classify environment. Yet, most existing research, temporal dimension problem is disregarded. In article, propose treating multivariate time-series classification (TSC) problem, explore various deep (DL) models. We demonstrate that TSC approach used monitor predict changes state, with greater compared conventional approaches ignore feature variation over time. Additionally, introduce new DL model for TSC, exploiting concept self-attention atrous spatial pyramid pooling. The proposed framework exploits only low power consumption sensors infer it outperforms state-of-the-art models, yielding higher combined smaller computational cost.

DECADE: A Deep Metric Learning Model for Multivariate Time Series
Determining similarities (or distance) between multivariate time series sequences is a fundamental problem in time series analysis. The complex temporal dependencies and variable lengths of time series make it an extremely challenging task. Most existing work either rely on heuristics which lacks flexibility and theoretical justifications, or build complex algorithms that are not scalable to bi...
متن کاملA deep learning architecture for temporal sleep stage classification using multivariate and multimodal time series
Sleep stage classification constitutes an important preliminary exam in the diagnosis of sleep disorders. It is traditionally performed by a sleep expert who assigns to each 30 s of signal a sleep stage, based on the visual inspection of signals such as electroencephalograms (EEG), electrooculograms (EOG), electrocardiograms (ECG) and electromyograms (EMG). We introduce here the first deep lear...

متن کاملDeep Symbolic Representation Learning for Heterogeneous Time-series Classification
In this paper, we consider the problem of event classification with multi-variate time series data consisting of heterogeneous (continuous and categorical) variables. The complex temporal dependencies between the variables combined with sparsity of the data makes the event classification problem particularly challenging. Most state-of-art approaches address this either by designing hand-enginee...
متن کاملMultivariate LSTM-FCNs for Time Series Classification
Over the past decade, multivariate time series classification has been receiving a lot of attention. We propose augmenting the existing univariate time series classification models, LSTM-FCN and ALSTM-FCN with a squeeze and excitation block to further improve performance. Our proposed models outperform most of the state of the art models while requiring minimum preprocessing. The proposed model...
