"valid feature" is a correct and usable part of a sentence in written English.
You can use it when you are describing something that is factually correct or has a legal basis. For example: "The competition rules were clearly laid out and had several valid features."
Besides robust parameter estimation, this task requires also selecting the regular objects and their valid feature sets (regular variants).
These dependencies and constraints describe the possible number of variants of the program: A valid feature configuration generates a specific variant with unique behavior.
The inflammation at vertebral corners is the most valid feature and has been observed related to the development of syndesmophytes by radiography [12], establishing a link between signs of disease activity and chronic structural changes.
Next, we explored another naturalistic or ecologically valid feature of natural biological motion perception, by contrasting tracking performance for walkers who moved across the screen in a manner that was consistent with their internal motion profile, with artificial moon-walkers, whose direction of motion did not match the direction in which they faced.
Our data showed that the presence of these antibodies is the most valid feature in patients with tumour or leukaemia versus patients with JIA, although the low number of tests taken in JIA patients makes the numbers less reliable.
In this study, we demonstrated that SWV is a valid feature for differentiating between benign and malignant solid breast masses and a cutoff value of 3.05 m/s for the total mass group.
Second, and following from the above, this conceptualisation of FTM should provide a comprehensive account of the situational features relevant to the exchange of the meaning-wording by the speaker-addressee: therefore, logically, it should include the valid features of other variant models such as Hymes' SPEAKING ([1986]: 59 65) or Gregory's 'functional tenor'.
Experiment 2 sought to investigate whether other naturalistic or ecologically valid features of biological motion could also influence MOT.
Arrays were scanned with Agilent's G2565AA Microarray Scanner System and analyzed using Agilent Feature extraction software (Agilent Technologies), which calculates log ratios and P values for valid features on each array and provides a confidence measure of gene differential expression by performing outlier removal, background subtraction, and dye normalization for each feature.
We extracted a group of 120 valid features to represent the protein sequence based on the distribution of AAs with certain physicochemical properties [ 22].
Next, we analyzed the physicochemical properties and distribution of whole amino acids and then extracted a group of 120-dimensional (120D) valid features to represent sequences.
