    The same theory describes every real closed field, not just the real numbers. [6] However, there are other number systems that are not accurately described by these axioms; in particular, the theory defined in the same way for integers instead of real numbers is undecidable , even for existential sentences ( Diophantine equations ) by ...

    The negative sampling method, on the other hand, approaches the maximization problem by minimizing the log-likelihood of sampled negative instances. According to the authors, hierarchical softmax works better for infrequent words while negative sampling works better for frequent words and better with low dimensional vectors. [ 3 ]

    The non-negative real numbers can be noted but one often sees this set noted + {}. [25] In French mathematics, the positive real numbers and negative real numbers commonly include zero, and these sets are noted respectively + and . [26] In this understanding, the respective sets without zero are called strictly positive real numbers and ...

    Negative numbers: Real numbers that are less than zero. Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero. When zero is a possibility, the following terms are often used: Non-negative numbers: Real numbers that are greater than or equal to zero. Thus a non-negative number is either zero or positive.

    In mathematics, a negative number is the opposite of a positive real number. [1] Equivalently, a negative number is a real number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency. A debt that is owed may be thought of as a negative asset.
