> the mapping absolutely isn’t mutable Assume f: X -> Y. We can now map x_1 to y_1 f(x_1)=y_1. And then change this same function by mapping x_1 to y_2: f(x_1)=y_2. Thus we can easily modify functions. Moreover, we do it constantly

Function is a mapping between two sets (of values). This mapping between values is mutable although the values are not.

> Data never changes, but we have the possibility to create a new version of the data. Well, it depends on what you mean by data. To avoid ambiguity it is better to talk about data values and data objects which have different prope

I agree that data modeling is underestimated but it hardly can be considered a solved problem. It is very hard because there are numerous alternative understandings and formal defs of what we mean by data (RM, 00, OR, MD etc.) In additiin,

The concept-oriented model tries to overcome some problems of RM by relying on two constructs: sets and functions . In contrast, RM uses only sets. The idea is that data can be stored in functions and transformed via operations with funct

From this (and many other) tutorial it is not clear if tensors in tensorflow are true mathematical tensors (that is, having covariant and contravariant indices) or they are multidimensional arrays. The name Tensorflow and terminology sugges

The lifetime word limit is a too rigid constraint. There should be a possibility to acquire (or lose) the points you can later use for publishing your results. Then the "price" of publishing negative results could be lower than ot

HPAT looks pretty promising. I wonder how they managed to signficantly increase performance of shuffling and sorting which are known to be quite difficult operations in map-reduce.
