QUESTION
I am new to Python, I am coming from C++ so I suspect my way of thinking is "tainted" by my preconceived notions. I will explain what I am trying to do and the issue I am facing, but please be aware that the code below is an "artificial" little example that reproduces my issue.
Say that at some point I have this scenario, where B only overrides A.plot_and_clear() as that is all I need from B:

should only be used to initialize an existing object. (Though the creation of the object and the call to __init__
usually both happen inside the call to the type itself.)
Use dedicated class methods as alternative constructors (such as copy constructors or constructing an object from another object). For example,
QUESTION
Currently, I'm working on a project where I need to extract the relevant aspects used in positive and negative reviews in real time.
For the notions of more negative and positive, it will be a question of contextualizing the word. Distinguish between a word that sounds positive in a negative context (consider irony).
Here is an example: Very nice welcome!!! We ate very well with traditional dishes as at home, the quality but also the quantity are in appointment!!!*
Positive aspects: welcome, traditional dishes, quality, quantity
Can anyone suggest to me some tutorials, papers or ideas about this topic?
Thank you in advance.
...ANSWER
Answered 2022-Mar-11 at 15:15This task is called Aspect Based Sentiment Analysis (ABSA). Most popular is the format and dataset specified in the 2014 Semantic Evaluation Workshop (Task 5) and its updated versions in the following years.
Overview of model efficiencies over the years:

Good source for ressources and repositories on the topic (some are very advanced but there are some more starter friendly ressources in there too):
https://github.com/ZhengZixiang/ABSAPapers
Just from my general experience in this topic a very powerful starting point that doesn't require advanced knowledge in machine learning model design is to prepare a Dataset (such as the one provided for the SemEval2014 Task) that is in a Token Classification Format and use it to fine-tune a pretrained transformer model such as BERT, RoBERTa or similar. Check out any tutorial on how to do fine-tuning on a token classification model like this one in huggingface. They usually use the popular task of Named Entity Recognition (NER) as the example task but for the ABSA-Task you basically do the same thing but with other labels and a different dataset.
Obviously an even easier approach would be to take more rule-based approaches or combine a rule-based approach with a trained sentiment analysis model/negation detection etc., but I think generally with a rule-based approach you can expect a much inferior performance compared to using state-of-the-art models as transformers.
If you want to go even more advanced than just fine-tuning the pretrained transformer models then check out the second and third link I provided and look at some of the machine learning model designs specifically designed for Aspect Based Sentiment Analysis.
QUESTION
I'm building a text editor using React with Typescript. The component hierarchy looks like this: TextEditor -> Blocks -> Block -> ContentEditable.
The ContentEditable is an npm package https://www.npmjs.com/package/react-contenteditable.
What i want it to do
The behavior I'm after is similar to Medium or Notions text editor. When a user writes in a block and hits enter on their keyboard, a new block should be created after the current block.
What it does
The behavior right now is strange to me. If I press enter and add one block, it works fine. But if I press enter again it overrides the previous block instead of creating a new one. However, if I press enter and add a block, then puts the carrot (focusing) on the new block and press enter again, a new block is added after as expected.

QUESTION
I am sorry if this question may sound a bit trivial for those who are more expert than me. If I have to create a long positive integer as well as find the number of zeros (with the following instruction as a hint: change the number to a string), do you know what I am supposed to do? Actually, these are some of the notions and examples that I'm focusing on to solve this problem.
I do not know whether the blue highlighted lines may be suitable for the assignment. There is no specified other info (if you are wondering, I have downloaded python 3.10, although typing the command python onto the panel of commands prompt, it pops up that the python's version in use is 3.6.6).
I am very sorry for this kind of question but I have just started moving my first step towards Python.

QUESTION
I have created an EKS cluster and deployed an API. My API needs to connect to a database that is not in AWS. In order to allow my API to use this database, I must authorize it's IP address in a whitelist. My problem is : I don't know how to get this IP adress since applications can be re-deployed and IP adresses can change... I'm not very familiar with networking notions and any detailed help can be very helpful since I don't only want the solution but also to understand how it works..
Thanks

You can associate an Elastic IP address with the worker node, adjust the security group where applicable, then specify nodeSelector
in your spec to run the special pod on the node. Finally you add the EIP to the whitelist.
QUESTION
For an array of n integers, there are C(n,2)= n(n−1) / 2 pairs of integers. Thus, we may check all n(n−1) / 2 pairs and see if there is any pair with duplicates.
I was poking around a LeetCode question and the answer for one of the algorithms included the above formula in the question explanation.
What is the point of the C(n, 2)
nomenclature on the left hand side of the equation? Is this a known/named standard that I can read and interpret, or is this some more general information that must/should be ascertained from context? I understand the math on the right, but I don't have any preconceived notions that adds any detail to my understanding from the function on the left.
What is the 2 doing?
...ANSWER
Answered 2021-Dec-13 at 06:30It's called binomial coefficient, or "nCk" or "n Choose k".
Here n is the size of the set, and k = 2 is the number of elements to select, so that e.g. sets {3, 6}
and {6,3}
taken are considered equal.
AFAIK, the standard notation in combinatorics is as shown above and spelled "n choose k", where as C(...)
is non-standard requiring clarification when first introduced.
QUESTION
I'm trying to create a well-formatted correlation matrix table with negative and positive values aligned. It would be great if there is a way to add whitespace before the positive values so that we can left-align them. But I'm stuck. Ideally I would like to achieve it with just tableOutput for shiny, but if there are other packages, I'm open to that as well.

QUESTION
Recording my desktop with ffmpeg (specially on Windows, less on Linux) I meet situations where/when ffmpeg complains about real time buffer size or thread queue size. I understand that the queue size is the number of frames that can reside in the queue and thus I am incited to think that it increases the buffer size as well. Can someone clarify these notions to me ?
...ANSWER
Answered 2021-Sep-05 at 17:02thread_queue_size
is applicable to all inputs and determines how many packets from that input can be queued at the application-level while waiting for ffmpeg to accept and process it in its main thread.
rtbufsize
is used by a handful of capture devices (mostly dshow
) to hold incoming frames while waiting for them to be transferred to the application-level queue for that input.
Neither option will adjust the value of the other, and you should set them both manually.
QUESTION
In the documentation :
BATCH: Commit the offset when all the records returned by the poll() have been processed.
MANUAL: The message listener is responsible to acknowledge() the Acknowledgment. After that, the same semantics as BATCH are applied.
if the offset is committed when all the records returned by the poll() have been processed for both cases then I don't get the difference, can you give me a scenario when MANUAL ack mode is used differently ?
If I use MANUAL mode and I don't call acknowledge()
within my KafkaListener would be the same as BATCH mode ? and if I call acknowledge()
what would change ?
Maybe I don't get the difference between commit and acknowledge notions within spring kafka
...ANSWER
Answered 2021-Aug-31 at 21:23In the perfect world, when your application is always UP, you definitely don't need those commits at all. Just because Kafka Consumer keeps the track of offset internally between poll calls. There might be the case when you really don't need to commit on every single batch delivered to you. That's when that MANUAL
comes to the rescue. With BATCH
mode you don't have control and the framework perform it for you anyway. With MANUAL
you may decide to commit now or later on, some where after a couple batches processed.
It is called acknowledge
because we might not perform a commit immediately, but rather store it in-memory for subsequent poll cycle. The commit must be performed exactly on the Kafka consumer thread.
