Goal: to run this Auto Labelling Notebook on AWS SageMaker Jupyter Labs.

Kernels tried: conda_pytorch_p36, conda_python3, conda_amazonei_mxnet_p27.

I have a dataset of tens of thousands of dialogues / conversations between a customer and customer support. These dialogues, which could be forum posts, or long-winded email conversations, have been hand-annotated to highlight the sentence containing the customers problem. For example:

Dear agent, I am writing to you because I have a very annoying problem with my washing machine. I bought it three weeks ago and was very happy with it. However, this morning the door does not lock properly. Please help

Dear customer.... etc

The highlighted sentence would be:

However, this morning the door does not lock properly.

1. What approaches can I take to model this, so that in future I can automatically extract the customers problem? The domain of the datasets are broad, but within the hardware space, so it could be appliances, gadgets, machinery etc.
2. What is this type of problem called? I thought this might be called "intent recognition", but most guides seem to refer to multiclass classification. The sentence either is or isn't the customers problem. I considered analysing each sentence and performing binary classification, but I'd like to explore options that take into account the context of the rest of the conversation if possible.
3. What resources are available to research how to implement this in Python (using tensorflow or pytorch)

I found a model on HuggingFace which has been pre-trained with customer dialogues, and have read the research paper, so I was considering fine-tuning this as a starting point, but I only have experience with text (multiclass/multilabel) classification when it comes to transformers.

I learned that you can redefine ContT from transformers such that the r type parameter is made implicit (and may be specified explicitly using TypeApplications), viz.:

I am new to Arrow and try to establish my mental model of how its effects system works; in particular, how it leverages Kotlin's suspend system. My very vague understanding is as follows; if would be great if someone could confirm, clarify, or correct it:

Because Kotlin does not support higher-kinded types, implementing applicatives and monads as type classes is cumbersome. Instead, arrow derives its monad functionality (bind and return) for all of Arrow's monadic types from the continuation primitive offered by Kotlin's suspend mechanism. Ist this correct? In particular, short-circuiting behavior (e.g., for nullable or either) is somehow implemented as a delimited continuation. I did not quite get which particular feature of Kotlin's suspend machinery comes into play here.

If the above is broadly correct, I have two follow-up questions: How should I contain the scope of non-IO monadic operations? Take a simple object construction and validation example:

I'm using jest to test a react TypeScript app.

This is the test I'm running:

https://hackage.haskell.org/package/transformers-0.6.0.2/docs/src/Control.Monad.Trans.Reader.html#ReaderT

I found that Reader is implemented based on ReaderT using Identity. Why don't make Reader first and then make ReaderT? Is there specific reason to implement that way?

I am getting the following error : attributeerror: 'dataframe' object has no attribute 'data_type'" . I am trying to recreate the code from this link which is based on this article with my own dataset which is similar to the article

I have several masked language models (mainly Bert, Roberta, Albert, Electra). I also have a dataset of sentences. How can I get the perplexity of each sentence?

From the huggingface documentation here they mentioned that perplexity "is not well defined for masked language models like BERT", though I still see people somehow calculate it.

For example in this SO question they calculated it using the function

Given an sklearn tranformer t, is there a way to determine whether t changes columns/column order of any given input dataset X, without applying it to the data?

For example with t = sklearn.preprocessing.StandardScaler there is a 1-to-1 mapping between the columns of X and t.transform(X), namely X[:, i] -> t.transform(X)[:, i], whereas this is obviously not the case for sklearn.decomposition.PCA.

A corollary of that would be: Can we know, how the columns of the input will change by applying t, e.g. which columns an already fitted sklearn.feature_selection.SelectKBest chooses.

I am not looking for solutions to specific transformers, but a solution applicable to all or at least a wide selection of transformers.

Feel free to implement your own Pipeline class or wrapper if necessary.
