Named entity recognition with deep Learning model - deep-learning

How to use named entity recognition using Deep Learning? I want to build a model using DL for named entity recognition.

There are many pre-trained models/library for Named Entity Recognition(NER), you can use HuggingFace pre-traied modes, SpaCy and NLTK for the same.
If you want to go deep dive and train a Deep Learning model from scratch, you shall explore about BERT.
Also, I would recommend to go through Kaggle notebooks about Named Entity Recognition.

How do you run deep learning models with parsnip?

I have explored the models offered with the R parsnip package listed at https://www.tidymodels.org/find/parsnip/ but I cannot find how to execute a generic deep learning model (by which I mean a deep-layered neural network). The closest I can find are mlp and bag_mlp.
By contrast, I know that the caret package supports at least two deep learning packages: https://topepo.github.io/caret/available-models.html.
Does parsnip not offer deep learning (yet) or am I missing something?
We don't have it via parsnip (at least not yet) since it is difficult to write a static set of tuning parameters for a network of arbitrary size and architecture.
If you want a tidy way to fit basic neural networks with multiple simple layers, the brulee package is helpful. brulee_mlp() can fit those (via torch) and has a recipes interface for easier preprocessing and feature engineering.
Also, though not part of tidymodels, there is the excellent luz package by Daniel Falbel. It's a nice interface to general deep learning models (also via torch).

Using OpenVino pre-trained models with AWS Sagemaker

I'm looking to deploy a pre-trained model for real-time pedestrian and/or vehicle detection using the AWS Sagemaker workflow, I particularly want to use Sagemaker Neo to compile the model and deploy it on the edge. I want to use one of OpenVino's prebuilt models from their model zoo, but when I download the model it is already in their Intermediate Representation (IR) format for their own optimizer.
Is there a way to get an OpenVino pre-trained model not in IR format so that I can use it in sagemaker? Or any possible way to containerize the OpenVino model for use in sagemaker?
If not, are there any free pre-trained models (using any of the popular frameworks like pytorch, tensorflow, ONXX, etc.) that I can use for vehicle detection from a traffic camera POV? AWS Marketplace does not seem to have much to offer in this regard.
Answers to the query as below:
No.Only in Intermediate Representation (IR) format.
There are a few OpenVINO pre-trained models available for vehicle detection.Check out the list of Object Detection Models that are relevant for vehicle detection on these Github pages.

Entity Linking and Recognition

I'm trying to build an entity recognition model using Spacy and that links any recognized set of entities to documents in the database.
My holdup for now is that I haven't found a good way of integrating the Sentiment analysis I'm to use with my model.
Do I really need a sentiment analysis?
All suggestions are welcome!!!

Pretraining a language model on a small custom corpus

I was curious if it is possible to use transfer learning in text generation, and re-train/pre-train it on a specific kind of text.
For example, having a pre-trained BERT model and a small corpus of medical (or any "type") text, make a language model that is able to generate medical text. The assumption is that you do not have a huge amount of "medical texts" and that is why you have to use transfer learning.
Putting it as a pipeline, I would describe this as:
Using a pre-trained BERT tokenizer.
Obtaining new tokens from my new text and adding them to the existing pre-trained language model (i.e., vanilla BERT).
Re-training the pre-trained BERT model on the custom corpus with the combined tokenizer.
Generating text that resembles the text within the small custom corpus.
Does this sound familiar? Is it possible with hugging-face?
I have not heard of the pipeline you just mentioned. In order to construct an LM for your use-case, you have basically two options:
Further training BERT (-base/-large) model on your own corpus. This process is called domain-adaption as also described in this recent paper. This will adapt the learned parameters of BERT model to your specific domain (Bio/Medical text). Nonetheless, for this setting, you will need quite a large corpus to help BERT model better update its parameters.
Using a pre-trained language model that is pre-trained on a large amount of domain-specific text either from the scratch or fine-tuned on vanilla BERT model. As you might know, the vanilla BERT model released by Google has been trained on Wikipedia and BookCorpus text. After the vanilla BERT, researchers have tried to train the BERT architecture on other domains besides the initial data collections. You may be able to use these pre-trained models which have a deep understanding of domain-specific language. For your case, there are some models such as: BioBERT, BlueBERT, and SciBERT.
Is it possible with hugging-face?
I am not sure if huggingface developers have developed a robust approach for pre-training BERT model on custom corpora as claimed their code is still in progress, but if you are interested in doing this step, I suggest using Google research's bert code which has been written in Tensorflow and is totally robust (released by BERT's authors). In their readme and under Pre-training with BERT section, the exact process has been declared. This will provide you with Tensorflow checkpoint, which can be easily converted to Pytorch checkpoint if you'd like to work with Pytorch/Transformers.
It is entirely possible to both pre-train and further pre-train BERT (or almost any other model that is available in the huggingface library).
Regarding the tokenizer - if you are pre-training on a a small custom corpus (and therefore using a trained bert checkpoint), then you have to use the tokenizer that was used to train Bert. Otherwise, you will just confuse the model.
If your use case is text generation (from some initial sentence/part of sentence), then I can advise you to check gpt-2 (https://huggingface.co/gpt2). I haven't used GPT-2, but with some basic research I think you can do:
from transformers import GPT2Tokenizer, TFGPT2Model
tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
model = TFGPT2Model.from_pretrained('gpt2')
and follow this tutorial: https://towardsdatascience.com/train-gpt-2-in-your-own-language-fc6ad4d60171 on how to train the gpt-2 model.
Note: I am not sure if DeBERTa-V3, for example, can be pre-trained as usual. I have checked their github repo and it seems that for V3 there is no official pre-training code (https://github.com/microsoft/DeBERTa/issues/71). However, I think that using huggingface we can actually do it. Once I have time I will run a pre-training script and verify this.

what is the type of deep learning algorithm in Rapidminer?

I use rapid-miner's deep learning operator for classification. But I can not find the type of deep learning algorithms.
Does Rapidminer use Convolutional Neural Networks (CNNs) or Recurrent Neural Networks (RNNs) or others?
Please help me.
RapidMiner provides an H2O integration for multi-layer feed-forward artificial neural networks.
There is also a new Kerras extension available which integrates an interface to the python library.
Regarding the DL4J project, you need to build the extension with gradle and then put the compiled *.jar file into the extension folder in your '.RapidMiner' folder.
Also feel free to ask further, or re-post, questions in the RapidMiner community forum.
This is just a regular MLP (many layers of fully connected neurons), as specified in the documentation, no convolutions, recurrence or anything more complex, just good old MLP.
