How to Compete for Zillow Prize at Kaggle

@machinelearnbot

Kaggle is an AirBnB for Data Scientists – this is where they spend their nights and weekends. It's a crowd-sourced platform to attract, nurture, train and challenge data scientists from all around the world to solve data science and predictive analytics problems through machine learning. It has over 536,000 active members from 194 countries and it receives close to 150,000 submissions per month. Started from Melbourne, Australia Kaggle moved to Silicon Valley in 2011, raised some 11 million dollars from the likes of Hal Varian (Chief Economist at Google), Max Levchin (Paypal), Index and Khosla Ventures and then ultimately been acquired by the Google in March of 2017. Kaggle is the number one stop for data science enthusiasts all around the world who compete for prizes and boost their Kaggle rankings.


A Beginner's Guide on Sentiment Analysis with RNN – Towards Data Science

@machinelearnbot

In order to feed this data into our RNN, all input documents must have the same length. We start building our model architecture in the code cell below. We have imported some layers from Keras that you might need but feel free to use any other layers / transformations you like. To summarize, our model is a simple RNN model with 1 embedding, 1 LSTM and 1 dense layers. We first need to compile our model by specifying the loss function and optimizer we want to use while training, as well as any evaluation metrics we'd like to measure.


4 Approaches To Natural Language Processing & Understanding - TOPBOTS

@machinelearnbot

In 1971, Terry Winograd wrote the SHRDLU program while completing his PhD at MIT. SHRDLU features a world of toy blocks where the computer translates human commands into physical actions, such as "move the red pyramid next to the blue cube." To succeed in such tasks, the computer must build up semantic knowledge iteratively, a process Winograd discovered was brittle and limited. The rise of chatbots and voice activated technologies has renewed fervor in natural language processing (NLP) and natural language understanding (NLU) techniques that can produce satisfying human-computer dialogs. Unfortunately, academic breakthroughs have not yet translated to improved user experiences, with Gizmodo writer Darren Orf declaring Messenger chatbots "frustrating and useless" and Facebook admitting a 70% failure rate for their highly anticipated conversational assistant M. Nevertheless, researchers forge ahead with new plans of attack, occasionally revisiting the same tactics and principles Winograd tried in the 70s. OpenAI recently leveraged reinforcement learning to teach to agents to design their own language by "dropping them into a set of simple worlds, giving them the ability to communicate, and then giving them goals that can be best achieved by communicating with other agents."


Apple's Core ML 2 vs. Google's ML Kit: What's the difference?

@machinelearnbot

At Apple's Worldwide Developers Conference 2018, the Cupertino company announced Core ML 2, a new version of its machine learning software development kit (SDK) for iOS devices. But it's not the only game in town -- just a few months ago, Google announced ML Kit, a cross-platform AI SDK for both iOS and Android devices. Both toolkits aim to ease the development burden of optimizing large AI models and datasets for mobile apps. So how are they different? Apple's Core ML debuted in June 2017 as a no-frills way for developers to integrate trained machine learning models into their iOS, macOS, and tvOS apps; trained models are loaded into Apple's Xcode development environment and packaged in an app bundle.


The Complete Natural Language Processing (NLP) Course

@machinelearnbot

Welcome to this course: The Complete Natural Language Processing (NLP) Course. Natural language processing (NLP) is a field of computer science, artificial intelligence and computational linguistics concerned with the interactions between computers and human (natural) languages, and, in particular, concerned with programming computers to fruitfully process large natural language corpora. Natural Language Processing (NLP) is used in many applications to provide capabilities that were previously not possible. It involves analyzing text to obtain intent and meaning, which can then be used to support an application. This comprehensive course will get you up-and-running with advanced tasks using Natural Language Processing Techniques with Python.



rOpenSci .rprofile: Julia Silge

@machinelearnbot

Dr. Julia Silge [@juliasilge on Twitter] is a data scientist at Stack Overflow. We talked about why R brings Julia joy, her path to a career in data science and what it was like to co-write a book for O'Reilly Media. This interview occurred on February 3, 2018 at the RStudio Conference in San Diego. KO: What is your name, job title, and how long have you been using R? JS: My name is Julia Silge and I'm a data scientist at Stack Overflow. I have been working in R for less than three years.

Create a Neural Network with Tensorflow.JS

@machinelearnbot

The neural network consists of an input layer with two nodes, a hidden layer with four nodes and an output layer with three nodes. Now we have built a model and we can test it with test data. The numbers should be similar to the numbers from the OutputLayer (ys). The smaller the difference, the better the model.
