Dataset: https://github.com/laxmimerit/All-CSV-ML-Data-Files-Download In this video, we will learn about spam text message classification using NLP. Natural Language Processing (NLP) is the field of Artificial Intelligence, where we analyze text using machine learning models. Text Classification, Spam Filters, Voice text messaging, Sentiment analysis, Spell or grammar check, Chatbot, Search Suggestion, Search Autocorrect, Automatic Review, Analysis system, Machine translation are the applications of NLP. Tokenization is breaking the raw text into small chunks. Tokenization breaks the raw text into words, sentences called tokens. These tokens help in understanding the context or developing the model for the NLP. The tokenization helps in interpreting the meaning of the text by analyzing the sequence of the words. 🔊 Watch till last for a detailed description 03:33 What is NLP? 09:38 Natural Language generation 12:42 Installing packages 21:11 Bag of words 27:07 Get started with Code 32:05 Balance the data 37:16 Exploratory data analysis 49:08 Pipeline and random forest 58:41 Support vector machine 👇👇👇👇👇👇👇👇👇👇👇👇👇👇 ✍️🏆🏅🎁🎊🎉✌️👌⭐⭐⭐⭐⭐ ENROLL in My Highest Rated Udemy Courses to 🔑 Unlock Data Science Interviews 🔎 and Tests 📚 📗 NLP: Natural Language Processing ML Model Deployment at AWS Build & Deploy ML NLP Models with Real-world use Cases.

In this lesson, we will learn how to perform image classification using Convolutional Neural Network (CNN) in MATLAB. Convolutional Neural Network (CNN) is a powerful machine learning technique from the deep learning domain. A collection of diverge image is required to train CNNs. The larger the collection the richer the features that CNN learns. These features often outperform features such as HOG, LBP or SURF. Training a CNN with large collection of diverse images is not an easy task. However, there is an easy way. We can use pertained CNN to leverage the power of CNN. It saves a huge amount of time and effort when we use pretrained CNN as feature extractor. In this lesson, I used ‘ResNet-50’ as pretrained CNN and Caltech101 image dataset. Image classification using convolutional neural network is a very exciting topic. Once you will have learned how to classify images using CNN, you can do what ever you want. For example – you can train classifier to identify brain tumor, cancer cell and skin diseases. Object recognition is another excellent field where you can use the method shown in this lesson. Image classification using CNN in MATLAB is not a straightforward approach. However, the strategy used in this lecture has made it simple. Each function used here, the role and outcome of each line and explanation with example where needed have made this lesson the best lesson on image classification using convolutional neural network in MATLAB. After completing this lesson, you will learn: 1. [More]

Now that we understand some of the basics of of natural language processing with the Python NLTK module, we’re ready to try out text classification. This is where we attempt to identify a body of text with some sort of label. To start, we’re going to use some sort of binary label. Examples of this could be identifying text as spam or not, or, like what we’ll be doing, positive sentiment or negative sentiment.

Hi! My name is Andre and this week, we will focus on text classification problem. Although, the methods that we will overview can be applied to text regression as well, but that will be easier to keep in mind text classification problem. And for the example of such problem, we can take sentiment analysis. That is the problem when you have a text of review as an input, and as an output, you have to produce the class of sentiment. For example, it could be two classes like positive and negative. It could be more fine grained like positive, somewhat positive, neutral, somewhat negative, and negative, and so forth. And the example of positive review is the following. “The hotel is really beautiful. Very nice and helpful service at the front desk.” So we read that and we understand that is a positive review. As for the negative review, “We had problems to get the Wi-Fi working. The pool area was occupied with young party animals, so the area wasn’t fun for us.” So, it’s easy for us to read this text and to understand whether it has positive or negative sentiment but for computer that is much more difficult. And we’ll first start with text preprocessing. And the first thing we have to ask ourselves, is what is text? You can think of text as a sequence, and it can be a sequence of different things. It can be a sequence of characters, that is a very low level [More]
Can AI be used to detect various diseases from a simple body scan? Yes! Normally, doctors train for years to do this and the error rate is still relatively high. From mammograms to cat scans, AI can diagnose a disease better than any human can if given the right training dataset. This will drastically reduce patient death, save medical practices a lot of money, and aid doctors in the patient care process. Everyone will win and its important to remember that AI won’t replace doctors, it will become the most powerful tool they’ve ever used. And once enough AI startups start impacting the field of healthcare, it will become as common a tool as the stethoscope has been.

Lecture 2 formalizes the problem of image classification. We discuss the inherent difficulties of image classification, and introduce data-driven approaches. We discuss two simple data-driven image classification algorithms: K-Nearest Neighbors and Linear Classifiers, and introduce the concepts of hyperparameters and cross-validation. Keywords: Image classification, K-Nearest Neighbor, distance metrics, hyperparameters, cross-validation, linear classifiers Slides: http://cs231n.stanford.edu/slides/2017/cs231n_2017_lecture2.pdf ————————————————————————————– Convolutional Neural Networks for Visual Recognition Instructors: Fei-Fei Li: http://vision.stanford.edu/feifeili/ Justin Johnson: http://cs.stanford.edu/people/jcjohns/ Serena Yeung: http://ai.stanford.edu/~syyeung/ Computer Vision has become ubiquitous in our society, with applications in search, image understanding, apps, mapping, medicine, drones, and self-driving cars. Core to many of these applications are visual recognition tasks such as image classification, localization and detection. Recent developments in neural network (aka “deep learning”) approaches have greatly advanced the performance of these state-of-the-art visual recognition systems. This lecture collection is a deep dive into details of the deep learning architectures with a focus on learning end-to-end models for these tasks, particularly image classification. From this lecture collection, students will learn to implement, train and debug their own neural networks and gain a detailed understanding of cutting-edge research in computer vision.
