From the User to the Medium: Neural Profiling Across Web Communities [article]

Mohammad Akbari, Kunal Relia, Anas Elghafari, Rumi Chunara
2018 arXiv   pre-print
As these groups and topics often arise organically, identifying the types of topics discussed is necessary to understand their needs.  ...  Thus here we develop an approach, NeuroCom, that optimally finds dense groups of users as communities in a latent space inferred by neural representation of published contents of users.  ...  Related Work Methods for identifying relevant groups is an active area of research; a great deal of work is on graph-based data such as social or information networks.  ...

., a week), a user may repeatedly follow a mixture of mobility profiles with certain probabilities associated with each of the profiles.  ...  In particular, we show that such profile based location predictions are more precise than common statistical approaches based on observed hub visitation frequencies alone.  ...  In particular, as seen in the cases for the users from groups G2, G3, G4 and G6 our predictions would be completely accurate, whereas those from the statistical method are far from correct.  ...

2006 Lecture Notes in Computer Science  
The rapid development of methods that select over/under expressed genes from microarray experiments have not yet matched the need for tools that identify informational profiles that differentiate between  ...  Consequently, we propose a procedure that, given certain user-defined preferences, generates an optimal suite of statistical methods.  ...  We have shown herein how commonly used statistical methods yield different results for the same data input: each statistical method applied neither identifies all observable differential profiles, nor  ...
