kandi X-RAY | construe Summary
Construe is a knowledge-based abductive framework for time series interpretation. It provides a knowledge representation model and a set of algorithms for the interpretation of temporal information, implementing a hypothesize-and-test cycle guided by an attentional mechanism. The framework is fully described in the following paper:. [1]: T. Teijeiro and P. Félix: On the adoption of abductive reasoning for time series interpretation, Artificial Intelligence, 2018, vol. 262, p. 163-188. DOI:10.1016/j.artint.2018.06.005. In this repository you will find the complete implementation of the data model and the algorithms, as well as a knowledge base for the interpretation of multi-lead electrocardiogram (ECG) signals, from the basic waveforms (P, QRS, T) to complex rhythm patterns (Atrial fibrillation, Bigeminy, Trigeminy, Ventricular flutter/fibrillation, etc.). In addition, we provide some utility scripts to reproduce the interpretation of all the ECG strips shown in paper [1], and to allow the interpretation of any ECG record in the MIT-BIH format with a command-line interface very similar to that of the WFDB applications.

As a followup question to my last (Perl XML::LibXML Getting info from specific nodes)
Given the following XML data, I can not figure out how to get the data that is shown after the tag (which has no ending tag without getting all of the data from the child nodes from within the section? See below for more specifics:

Hello I had previous help on this query SQL JOIN WITH NESTED QUERY and thanks to @GordonLinoff it works great. My question is I need to add more columns and am thinking this can be done with a nested query but I am not getting the same 10 values that I should be getting from the original query. The reason I believe it would be a nested query is because adding any columns to the below query requires me to add it to the group by clause and that construes my results. Any help on this nested query would be very helpful. This is the query that is working great and giving me the results I need

Answered 2021-May-26 at 07:59As far as I can see your issue is caused by the lack of word wrapping. Your last table row has a long uninterrupted string: the link with the UTM-tags. If you'd remove the utm-tags from it, the cropping would not persist.

"Clojure metaphysics construes identity as something we humans impose on a succession of unchanging values produced by a process over time".
If this is true, if identity surronds all these states, then I should be able to do something like this.
...ANSWER
Answered 2021-Jan-03 at 23:48If this is true, if identity surronds all these states, then I should be able to do something like this.
I don't really see any justification for this "should", philosophically. "Aaron Bell" is an identity that encompasses many states you have been in in the past, but I can't interact with, or even observe, any of those past states. The only way I would know about any of them is if somebody had observed them and written down those observations in some immutable object that I can refer to.
Clojure's identities behave the same way: you can take a snapshot at any time, and after you do, you can look at that snapshot whenever you want. But states nobody looked at are lost forever.

QUESTION
I'm trying to understand how the Cloud Firestore read quota works. I have read this post and the response to it. My console was open, but I cannot construe how a single collection with 3 documents, each having 2 attributes constitutes a "busy console".
I'm struggling to make sense of the documentation.
I have two collections in firestore. Each one has 3 documents. Each document has 2 attributes. I'm using those attributes to populate options in the Autocomplete select menu from Material UI.
In localhost, I have been running the form to test getting those attributes into an Autocomplete select menu, using a single snapshot. In 30 seconds, these two form items produced 1.1k reads in firestore.
I thought:
snapshot only updated when data in firestore changed.
that by using unsubscribe, then the hook would stop listening for changes in firestore.
efficiency of the firestore read was improved by adding the state of the list as a dependency to the hook (the orgList at the end of the useEffect block): https://medium.com/javascript-in-plain-english/firebase-firestore-database-realtime-updates-with-react-hooks-useeffect-346c1e154219.
Can anyone see how 1.1k reads are being generated by running this form with 2 input items only (there are no other firestore calls in the whole app at the moment).
...ANSWER
Answered 2020-Jul-23 at 19:38A solution that worked for many is to use cache rather than reading from Firestore constantly.

Along with the general data model for knowledge description and the interpretation algorithms, a comprehensive knowledge base for ECG signal interpretation is provided with the framework, so the software can be directly used as a tool for ECG analysis in multiple abstraction levels.
