The phrase "altering the threshold" is correct and usable in written English.
It can be used in contexts where you are discussing changes to a limit or standard, often in technical, scientific, or metaphorical discussions.
Example: "The researchers are altering the threshold for detecting the presence of the chemical in the samples."
Alternatives: "modifying the limit" or "changing the standard."
However altering the threshold value based on the SNR may result in a significant increase in accuracy.
Thus, altering the threshold level of 10−4, used for discriminating the basis functions, did not change the basis selection results.
Taken together, our results indicate that altering the threshold levels of hox transcripts can trigger a heterochronic shift of shh expression in pectoral fin primordia, and the subsequent temporal shift of Shh activity causes changes in the size of the fin endoskeleton.
Indeed altering the threshold, so that fewer samples are called at one copy improves the significance level slightly to 0.015.
The scalability of triage tools may aid in decision making by objectively altering the threshold for admission to critical care.
The brain could implement a change in excursion by altering the threshold level of LIP firing rate necessary to commit to a choice.
Early encounters with pain may alter the threshold at which pain is felt later on, making a child hypersensitive to pain — or, alternatively, dangerously indifferent to it.
The Smith Commission recommended the Scottish Parliament be given the power to set income tax rates and bands, but not to alter the threshold above which tax is paid.
He postulated that RES might be an example of Angry Back-firing C-nociceptors syndrome, in which the phenomenon of 'cross-modality threshold stimulation' occurs, whereby temperature changes alter the threshold for the pain induced by mechanical stimulation [25].
The dampening of p21ras-ERK activation during an increase in adhesion and conjugation induced by SKAP-55 could alter the threshold of T-cell activation.
For example, it is common for tumor cells to express high levels of anti-apoptotic proteins that interrupt the catalytic cascade [35], or which otherwise alter the threshold of caspase-8 activation required for apoptosis [36], [37].
