Nevertheless, most existing supervised hashing schemes suffer from the following limitations: (1) severe quantization error caused by continuous relaxation of binary codes; (2) disturbance of unreliable codes in subsequent hash function learning; and (3) erroneous guidance derived from imprecise and incomplete semantic labels.
Of these, 81 genes encoded possible amino acid sequences, while remaining 53 candidates showed that deduced coding sequences are too short, compared to transcript sizes (i.e., A deduced coding region comprises less than 20% of an entire transcript sequence), or displayed unreliable coding regions (multiple small coding regions).
The other 110 genes were eliminated from consideration because they displayed unreliable coding sequences (53 genes), were undetected or detected with unexpected sizes in the PCR assay (25 genes), not specifically or predominantly expressed in the testis (19 genes) or undetected in the Northern blot analysis (13 genes).
This approach [ 26, 27] entails first removing claims that are considered to have unreliable diagnosis coding, such as those for testing procedures used to rule out conditions.
Just over one-third (33,388, or 34.4%) were excluded for the following reasons: being in a Medicare HMO (22.8%), unreliable diagnosis coding (4.0%), not having both Medicare parts A and B insurance coverage (5.5%), month and year of death the same as the diagnosis (2.6%), unknown month of diagnosis (0.7%) and/or unknown cause of death (0.5%).
After the initial homework and targeted instruction on evolutionary relationships, and disregarding the individual component of the evolution unit exam (unreliable for correctness coding), approximately half of the students demonstrated such understanding across multiple assessments (Table 4).
Bitcoin, however, was doomed if the code was unreliable.
The Finnish Hospital Discharge Register (FHDR) includes information on surgical procedures since 1987, but the codes were unreliable until 1990.
Exploratory analysis indicated that these codes were unreliable to estimate time-with-diabetes prior to 2004.
The CPRD recording of suicide using Read codes is unreliable, with significant inaccuracy (over- and under-reporting).
However, structured patient data may be unavailable, for example when i) a physician does not enter patient data or enters data as non-computer-interpretable free text, which occurs often [ 7], ii) data coding is unreliable, also a frequent problem [ 8], or iii) a physician reads a guideline for educational purposes rather than searching for information relating to a given patient.
