Text Classification

Text classification has numerous applications, from tweet sentiment, product reviews, toxic comments, and more. It's a popular project topic among Insight Fellows, however a lot of time is spent collecting labeled datasets, cleaning data, and deciding which classification method to use. Services like Clarifai, and Google AutoML have made it very easy to create image classification models with less labeled data, but it's not as easy to create such models for text classification. For image classification tasks, transfer learning has proven to be very effective in providing good accuracy with fewer labeled datasets. Transfer learning is a technique that enables the transfer of knowledge learned from one dataset to another.

Explain Like I am 5. It is the basic tenets of learning for me where I try to distill any concept in a more palatable form. I couldn't reduce it to the freshman level. That means we don't really understand it. So, when I saw the ELI5 library that aims to interpret machine learning models, I just had to try it out.

WHAT YOU WILL LEARN Understand how to interpret the result of Logistic Regression model and translate them into actionable insight Learn how to solve real life problem using the different classification techniques Predict future outcomes basis past data by implementing Machine Learning algorithm Course contains a end-to-end DIY project to implement your learnings from the lectures The course "Machine Learning Basics: Classification models in Python" teaches you all the steps of creating a Classification model to solve business problems. Below is a list of popular FAQs of students who want to start their Machine learning journey- What is Machine Learning? Machine Learning is a field of computer science which gives the computer the ability to learn without being explicitly programmed. It is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention. Which all classification techniques are taught in this course?

In this article, we will utilize Tensorflow 2.0 and Python to create an end-to-end process for classifying movie reviews. Most Tensorflow tutorials focus on how to design and train a model using a preprocessed dataset. Typically preprocessing the data is the most time-consuming part of an AI project. This article will walk you through this process. Note: we are not trying to generate a state of the art classification model here.

Hello everybody We're excited to share our **classification feature**; we've been working on it for a while now and iterating on it based on feedback from our customers. These are the highlights: **Active learning** it minimizes the effort while tagging and training models. That means we had to build an extremely reliable service that can tackle high volume transactions in real time. I wanted to share some of the **top 3 most frequent use cases** we've seen so far. We're amazed by how business teams are leveraging our AI technology in their operations without the need of technical skills!

In this AI Builder three-part blog series, first blog was about how to use AI Builder to extract Form document data and second blog highlighted the use of AI Builder Text classification model. Now in the third and final blog we will see how to build an AI Object Detector using Power Platform. Object detection refers to the capability of computer and software systems to detect images, locate objects in an image and identify each object. Object detection can be used to expedite or automate business processes in multiple industries. AI Object detection is a new feature in Power Platform which can be accomplished using AI Builder.

I have a dataset of 8 million unique members, approximately 800 million records. Of those 8 million members I have a positive sample of about 25000. I would like to not simply downsample although the downsampled RF performs pretty well. The data is on a Hadoop cluster. I only have access to it via a Zeppelin notebook with PySpark.

Sentiment classification is an important process in understanding people's perception towards a product, service, or topic. Many natural language processing models have been proposed to solve the sentiment classification problem. However, most of them have focused on binary sentiment classification. In this paper, we use a promising deep learning model called BERT to solve the fine-grained sentiment classification task. Experiments show that our model outperforms other popular models for this task without sophisticated architecture. We also demonstrate the effectiveness of transfer learning in natural language processing in the process.

Natural Language Processing (NLP) is a massive space within artificial intelligence (AI), which enterprises are integrating into their existing platforms more each day. As petabytes of textual data become available each day, companies can leverage NLP to retrieve deeper insights. Aspects such as entities, sentiment, emotion, and keywords can be extracted from textual data and enterprises can leverage this information to pivot, understand customer sentiment, and improve internal efficiency. Watson Natural Language Understanding (NLU) and Watson Natural Language Classifier (NLC) are cutting-edge NLP technologies that provide deep insight into textual data. Watson NLU provides insight such as entities, emotion, keywords, sentiment, and categories, while Watson NLC allows users to train a classification model in under 15 minutes and classify text.

In this paper, we focus on the classification of books using short descriptive texts (cover blurbs) and additional metadata. Building upon BERT, a deep neural language model, we demonstrate how to combine text representations with metadata and knowledge graph embeddings, which encode author information. Compared to the standard BERT approach we achieve considerably better results for the classification task. For a more coarse-grained classification using eight labels we achieve an F1- score of 87.20, while a detailed classification using 343 labels yields an F1-score of 64.70. We make the source code and trained models of our experiments publicly available.
