The unreliable features are then reconstructed, or marginalized (ignored in score computation).
A report by an EU consumer watchdog has flagged up myriad problems with smartwatches designed for children, including security flaws, privacy concerns, and risks posed by unreliable features.
Missing data approach is also investigated in several studies [31 34], where a binary time-frequency mask is constructed for the noisy spectrum to indicate reliable and unreliable features.
Additionally, the authors of [20, 21] also considered the implementation of observation weights and contextual information in an effort to emphasize the reliable features whilst simultaneously attenuating the unreliable features.
This classification strategy results in sparse and isolated masked features, like the squares of a chess-board, while oracle reliable and unreliable features tend to be clustered into consistent time frequency blocks.
Last month the Norwegian Consumer Council put out a report about children's smartwatches, raising concerns about security flaws, privacy concerns, and risks posed by what they described as unreliable features.
In response to New Jersey's mandate and pressure from gun control groups, the National Rifle Association NRAA) said that it was "opposed to government mandates that require the use of expensive, unreliable features, such as grips that would read your fingerprints before the gun will fire".
Unreliable features, marked in the feature extraction software, and spots not showing signal-to-noise ratios ≥ 3, for both channels, were removed.
Such heterogeneity may not have been discernable in vitrified specimens and may have produced unreliable features in a 3D reconstruction determined by cryo-EM of vitrified specimens.
