In common usage and linguistics, concision (also called conciseness, succinctness, [1] terseness, brevity, or laconicism) is a communication principle [2] of eliminating redundancy, [3] generally achieved by using as few words as possible in a sentence while preserving its meaning. More generally, it is achieved through the omission of parts ...
In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).
Accuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition. That is, the accuracy is the proportion of correct predictions (both true positives and true negatives) among the total number of cases examined. [10]
Brevity is concision or brevitas, the quality of being brief or concise, or: Brevity (comic strip), a comic strip created by Guy Endore-Kaiser and Rodd Perry;
Precision takes all retrieved documents into account. It can also be evaluated considering only the topmost results returned by the system using Precision@k. Note that the meaning and usage of "precision" in the field of information retrieval differs from the definition of accuracy and precision within other branches of science and statistics.
Another reason the precision matrix may be useful is that if two dimensions and of a multivariate normal are conditionally independent, then the and elements of the precision matrix are . This means that precision matrices tend to be sparse when many of the dimensions are conditionally independent, which can lead to computational efficiencies ...
Brevity should never overrule clarity or accuracy; however, a lack of brevity can interfere with clarity and render accuracy irrelevant. Upon finishing a piece of writing/editing, one should ask oneself: "Is there a shorter and clearer way to say this? Can I rearrange this and eliminate conjunctions or clauses? What does each word accomplish?"
In a Harvard Business Review article, Kabir Sehgal enumerated three main ways to format emails with military precision: (1) Subject with key words – Key words specify the nature in email (e.g. Action, Sign, Info, Decision, etc.); (2) Bottom Line Up Front (BLUF) – Emails should be short that basically answers the 5W's: who, what, when, where ...
