Looking for ideas on how to deal with massive raw data sifting


Recommended Posts

Hello everybody.

I'm looking for ideas on how to deal with finding patterns in raw data, when the pattern may not be known ahead of time.

I have lots of lists of some small, but mostly blocks of large number strings. I need to be able to sort out the patterns and identify the ones that are repeating.

As an example, here is one of the strings:

11235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011235831459437077415617853819099875279651673033695493257291011

As you can see visually in the block, there is a repeating number sequence. But in this sequence itself, there are repeating patterns. These other patterns show up in other data blocks, and I need to index them to related sequences.

Here is a second block with the related sequences.

I'm mainly looking for direction in how to tackle the issue.

Thanks for looking.

Maybe you can mimic algorithms used to detect sequences in DNA data.

Google for that. For instance: https://pastel.archives-ouvertes.fr/tel-01762479/document

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.

RegExp tutorial: enough to get started
PCRE v8.33 regexp documentation latest available release and currently implemented in AutoIt beta.

SQLitespeed is another feature-rich premier SQLite manager (includes import/export). Well worth a try.
SQLite Expert (freeware Personal Edition or payware Pro version) is a very useful SQLite database manager.

Something like this here?:

UEZ, That is an approach I hadn't thought of. I'll play more with that.

jacd, first pass of the white paper, and I think this is what I need. I knew it was out there, but I couldn't find it looking though my math encyclopedia. Thanks for leading me to that.

This is one of the application domains for Bloom filters. I'm sure there is significant litterature about dissecting DNA sequences and by extension sequences of symbols repeating in a large string of symbols in a given set, here digits.
