We established a Spatio-Temporal Neural Network, namely STNN, to forecast the spread of the coronavirus COVID-19 outbreak worldwide in 2020. The basic structure of STNN is similar to the Recurrent Neural Network (RNN) incorporating with not only temporal data but also spatial features.
How would you explain spatio-temporal?
Spatial refers to space. Temporal refers to time. Spatiotemporal, or spatial temporal, is used in data analysis when data is collected across both space and time. It describes a phenomenon in a certain location and time — for example, shipping movements across a geographic area over time (see above example image).
What is spatio-temporal convolutional neural networks?
A spatial–temporal Convolutional Neural Network is designed to automatically extract spatial–temporal features of the crowd. • The performance of anomaly detection is improved when the analysis is concentrated on the dynamic regions only.
What is temporal neural network?
Temporal neural networks (TNNs) are SNNs that communicate and process information encoded as relative spike times (in contrast to spike rates). A TNN architecture is proposed, and, as a proof-of-concept, TNN operation is demonstrated within the larger context of online supervised classification.
What is spatio-temporal dataset?
Spatio-temporal dataset consists of data that depends both on time and geographic location. For example, a dataset that consists of the path of an aeroplane is spatio-temporal as it consists of both time and geographic information of that aeroplane.
What does spatio mean?
Belonging to both space and time or to space–time.
What is temporal domain?
The temporal domains carries no information about frequency or sequence. … The only information carried in the temporal domain are the distances between events relative to the distances between other events; for example “There is twice as much time between A and X as there is between G and Q”.
What is temporal convolution?
Temporal convolutional network (TCN) is a framework which employs casual convolutions and dilations so that it is adaptive for sequential data with its temporality and large receptive fields.
What is difference between CNN and RNN?
The main difference between CNN and RNN is the ability to process temporal information or data that comes in sequences, such as a sentence for example. … Whereas, RNNs reuse activation functions from other data points in the sequence to generate the next output in a series.
How do RNN work?
Recurrent neural networks (RNN) are a class of neural networks that are helpful in modeling sequence data. Derived from feedforward networks, RNNs exhibit similar behavior to how human brains function. Simply put: recurrent neural networks produce predictive results in sequential data that other algorithms can’t.
Is RNN and Lstm same?
LSTM networks are a type of RNN that uses special units in addition to standard units. LSTM units include a ‘memory cell’ that can maintain information in memory for long periods of time. A set of gates is used to control when information enters the memory, when it’s output, and when it’s forgotten.
