 - Tensors: A tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space. Tensors are a generalisation of scalars and vectors; a scalar is a zero rank tensor, and a vector is a first rank tensor. The rank (or order) of a tensor is defined by the number of directions (and hence the dimensionality of the array) required to describe it. It can be thought of as a multidimensional numerical array. An example of a tensor would be 1000 video frames of 640×480 size.  - Tensors: A tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space.

 - Vector: Vectors are used to represent both the input data (features) and the output data (labels or   predictions). Each data point is represented as a feature vector, where each component of the vector corresponds to a specific feature or attribute of the data. - Vector: Vectors are used to represent both the input data (features) and the output data (labels or   predictions).

-- Temperature: Temperature in AI settings control the diversity and creativity of the generated text. Value ranges between 0 and 2 depending on model. Higher temperature values result in more diverse outputs but less logically coherent, while lower values lead to more focused and deterministic text. +- Temperature: Temperature in AI settings control the diversity and creativity of the generated text.
