Expert writing Tips

Best practice

When referring to inadequate sampling, use the single-word form "undersampling" to ensure grammatical correctness and clarity. This is especially important in formal writing and technical contexts.

Common error

Avoid using "is under sampling" as separate words when the intended meaning is that the sampling itself is insufficient. The correct form in most contexts is "is undersampling". The separated form could be interpreted as being under an act of sampling which is almost never the meaning that is intended.

Linguistic Context

The phrase "is under sampling" functions as a verb phrase attempting to describe an ongoing action related to data collection. However, it is considered grammatically incorrect by Ludwig AI, and the intended meaning is usually better conveyed by "undersampling" as a single word.

Ludwig's WRAP-UP

In summary, while the phrase "is under sampling" might appear in some contexts, Ludwig AI identifies it as grammatically incorrect. The intended meaning, which is to convey that a sampling process is insufficient, is better and more accurately expressed by using the single-word verb "undersampling" or alternative phrases like "is sampling insufficiently". Given its infrequent and questionable usage, it's best to opt for grammatically sound alternatives, especially in formal or scientific writing. The most authoritative sources tend to avoid this construction in favor of more precise language.
