I am specifically training a simple convolutional neural network based text classification model to classify sentiment of tweets . I will be using the tensorflow gpu version The dataset is from the Tweet Sentiment Extraction challenge from Kaggle(https://www.kaggle.com/c/tweet-sentiment-extraction/overview) We would implement text classification using a simple neural network developed using Tensorflow on tweet data to classify tweets as "positive", "negative" or "neutral" The code is present here: https://github.com/rsreetech/TextClassificationTensorFlowCNN

I have pre-processed this dataset. The script for pre-processing is present here: https://github.com/rsreetech/TextClassificationLSTMTensorFlow/blob/master/AmazonReviewsPreprocessing.ipynb Let us perform sentiment classification by considering reviews which have rating 3(3,4,5) and above as having positive sentiment and reviews having ratings below 3(1,2) as negative sentiment. Let us develop a LSTM based classification model for sentiment classification on review data. The code is present here: https://github.com/rsreetech/TextClassificationLSTMTensorFlow/
Lecture 4 :
Word2Vec Detailed Explanation and Train your Custom Word2Vec Model using Genism
In this video I will be explaining about Word2Vec and how to train your custom Word2Vec Model using genism in Python.
Lecture 5 :
ZeroShotTextClassification
In this video I explain about Zero Shot Text Classification and Textual Entailment. Traditionally, zero-shot learning (ZSL) most often referred to a fairly specific type of task: learn a classifier on one set of labels and then evaluate on a different set of labels that the classifier has never seen before. Recently, especially in NLP, it's been used much more broadly to mean get a model to do something that it wasn't explicitly trained to do. A well-known example of this is in the GPT-2 paper where the authors evaluate a language model on downstream tasks like machine translation without fine-tuning on these tasks directly. I explain about how textual entailment is used in the context of zero shot learning. I also explain about Hugging face zero shot text classification pipeline with a demo
Lecture 6 :
TextClassificationBERT
In this video I will be explaining my solution to Kaggle Natural Language Processing with Disaster Tweets (Getting Started Competition). I will be using BERT(Tensorflow) in the solution The main purpose of the competition is Twitter has become an important communication channel in times of emergency. The ubiquitousness of smartphones enables people to announce an emergency they’re observing in real-time. Because of this, more agencies are interested in programmatically monitoring Twitter (i.e. disaster relief organizations and news agencies).
Lecture 7 :

The dataset is from the Tweet Sentiment Extraction challenge from Kaggle(https://www.kaggle.com/c/tweet-sentiment-extraction/overview) We would perform text classification using spaCy on tweet data to classify tweets as "positive", "negative" or "neutral" The code is present here: https://github.com/rsreetech/TextClassificationWithSpacyV3.0
Lecture 8 :
SpacyV3CustomNamedEntityRecognition
In this video I will be explaining how we perform Custom Named Entity (Disease) Recognition in clinical text with spaCy v3 transformers in Python|. I am using the latest version of spaCy v3.0 here. There are differences on the training method when compared to spaCy v2.0 Here I will be creating a clinical named entity recognition transformers based model which can recognize the disease names from clinical text For this I have extracted annotated clinical text from the following github repo: https://github.com/dmis-lab/biobert They provide annotated clinical text here: Named Entity Recognition: (17.3 MB), 8 datasets on biomedical named entity recognition(https://drive.google.com/open?id=1OletxmPYNkz2ltOr9pyT0b0iBtUWxslh) This custom name entity(disease) recognition model achieves around 90% f1-score on the dataset with 10 epochs of training. The code is present here: https://github.com/rsreetech/CustomeNERspaCyv3.0

In this video I demonstrate using a Kaggle notebook how topic modelling and semantic search can be done using Top2Vec python library. Top2Vec is an algorithm for topic modeling and semantic search. It automatically detects topics present in text and generates jointly embedded topic, document and word vectors. Once you train the Top2Vec model you can: • Get number of detected topics. • Get topics. • Get topic sizes. • Get hierarchichal topics. • Search topics by keywords. • Search documents by topic. • Search documents by keywords. • Find similar words. • Find similar documents. • Expose model with RESTful-Top2Vec
