In both training and evaluation, a long input sequence can be processed as a whole in a temporal-convolutional-network (TCN), instead of sequentially as in RNN. Unlike in RNNs where the predictions for later timesteps must wait for their predecessors to complete, convolutions can be done in parallel since the same filter is used in each layer. An added benefit of TCN can change its receptive field size in multiple ways. For instance, stacking more dilated (causal) convolutional layers, using larger dilation factors, or increasing the filter size are all viable options (with possibly different interpretations). TCNs thus afford better control of the model’s memory size, and are easy to adapt to different domains.
Unlike recurrent architectures, TCN has a backpropagation path different from the temporal direction of the sequence. A dynamic receptive field size provides flexibility.
Why are Parallelism, Flexiblity, and Stablility important features for using machine learning to analyzes sleep & vital signs?
Because they enable you to handle vast volumes of data in an effective and fast manner and allow you to modify the analysis as necessary, parallelism, flexibility, and stability are essential characteristics for utilizing machine learning to assess sleep and vital signs.
Similarities: Both sleep and vital sign data frequently require speedy processing of vast amounts of information. By dividing the workload among several processors, parallel processing speeds up the processing process.
Flexibility: To get the desired results from the analysis of sleep and vital sign data, the algorithm frequently has to be changed. The algorithm can be changed without having to start over, which saves time and resources.
Stability: It's crucial to make sure that the analysis is accurate and trustworthy while working with sensitive health data. The capacity of the algorithm to deliver consistent results even in the presence of unexpected inputs or changes in the data is referred to as stability. This contributes to the results' accuracy and dependability.

Parallelism allows for faster processing of the input sequence, making the model more efficient and scalable. Flexibility allows the model to adapt to different domains and changing data patterns, improving its ability to generalize to new data. Stability helps ensure consistent and reliable results, reducing the risk of overfitting and improving the overall accuracy of the model. These features are important when analyzing sleep and vital signs because they help improve the speed, accuracy, and reliability of the analysis, which are critical for making informed decisions and decisions based on the results.
