Has any reader of this question, access to such neural network or other ML tool that predicts the next symbol given some prior sequence?

I am researching random number generation techniques, and would like to find a neural network or other machine learning software, that is able to track the sequences that my software generates, in...

The de Bruijn sequences are a set of Eulerian paths on a directed graph. How may one construct a Hamiltonian path upon these Eulerian paths?

Every Eulerian path constitutes a node in a graph. By what set of operators may these Eulerian paths be organised into a graph such that one may compute upon that graph all possible Hamiltonian...

Why does the standard numbering equation for de Bruijn sequences give differing results for dB(16,4) and dB(2,16), when both are 16 bits?

De Bruijn sequences are numbered by the equation dB(k,n) = ((k!)^(k^(n-1)))/(k^n). When we have dB(2,16), the computed value is of the order 2.1598E+9859 . For dB(16,4), the computed value is of...

Why is it that within a maximally disordered object, we yet find examples of order?

De Bruijn sequences are maximally disordered. Yet, they are computable. This implies that de Bruijn sequences retain yet a hint of order. Ordered objects like crystals have a regular structure...

How might the LZW data compression algorithm yield a de Bruijn sequence as output?

Generally, data compression is the act of removing redundancy (a lack of distinction, also know as repetition or order), and as de Bruijn sequences are maximally disordered, it must be the task of...

Again, not a question. This time, an observation. We seek comment.

The impending conversion of education, from the centralised academy model to the cottage model, including home schooling via MOOC, leads to the notion that RG and other similar media (like...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...

Can we distinguish the type of free fluid inside the pelvic and abdominal cavities whether blood or serous fluid using the ultrasound?

during ultrasound examination of acute abdomen, sometimes we see free fluid , can we know the type of fluid ,whether blood or not , using ultrasound only? if yes , what are the sonographic...
