Top 5 Data Science GitHub Repositories, Reddit Discussions - Feb 2019
Let me know in the comments section below if you use it! I like this question because of how relevant it is in today's world. The thread has close to 200 comments from experienced data scientists and machine learning researchers debating whether these coding challenges are a good or bad thing in an interview round. There's a lot of experience here so this is a discussion you really should pay close attention to. The essential question it comes down to is โ should data science/machine learning professionals be judged extremely tightly on their coding skills or should algorithms/concepts take preference?
Use AI to Add Depth of Field to Any Photo Using This App
If you have a newer smartphone, then it likely came with the ability to shoot 3D images, or at least images with some depth of field involved. Making that happen requires your phone to have two cameras. If it doesn't then you stuck taking two-dimensional pictures. Dpth is a smartphone app for iOS and Android that takes your run-of-the-mill 2D pictures and uses AI to transform them into an image where you can play around with the depth of field. After trying it with a number of photos, I can tell you your mileage will vary depending on what type of photo you're trying to use it with.
QuickStop: A Markov Optimal Stopping Approach for Quickest Misinformation Detection
Wei, Honghao, Kang, Xiaohan, Wang, Weina, Ying, Lei
This paper combines data-driven and model-driven methods for real-time misinformation detection. Our algorithm, named QuickStop, is an optimal stopping algorithm based on a probabilistic information spreading model obtained from labeled data. The algorithm consists of an offline machine learning algorithm for learning the probabilistic information spreading model and an online optimal stopping algorithm to detect misinformation. The online detection algorithm has both low computational and memory complexities. Our numerical evaluations with a real-world dataset show that QuickStop outperforms existing misinformation detection algorithms in terms of both accuracy and detection time (number of observations needed for detection). Our evaluations with synthetic data further show that QuickStop is robust to (offline) learning errors.
China's Xinhua presents news using robot anchor - Times of India
SINGAPORE: China's Xinhua state news agency on Sunday used a lifelike robotic news anchor that mimics human facial expressions and mannerisms to present a story about delegates attending an annual parliament meeting arriving in Beijing. The artificial intelligence robot named "Xin Xiaomeng" sported a short haircut and wore a pink blouse and earrings in a one-minute video presentation by Xinhua. Xinhua displayed two AI news anchors dressed in men's clothes last November at the World Internet Conference in the eastern Chinese town of Wuzhen. China is pushing to advance its prowess in AI technology, from surveillance equipment to self-driving cars.
MIT Introduction to Deep Learning โ TensorFlow โ Medium
Designing the course and the labs to be accessible to as many people as possible was a big priority for us. So, Lecture 1 focuses on neural network fundamentals, and the first module in Lab 1 provides a clean introduction to TensorFlow, and is written in preparation for the upcoming release of TensorFlow 2.0. Our introduction to TensorFlow exercises highlight a few key concepts in particular: how to execute computations using math operators, how to define neural network models,and how to use automatic differentiation to train networks with backpropagation. Following the Intro to TensorFlow module, Lab 1's second module dives right into building and applying a recurrent neural network (RNN) for music generation, designed to accompany Lecture 2 on deep sequence modeling. You'll build an AI algorithm that can generate brand new, never-heard-before Irish folk music.
Building a Movie Recommendation Engine in Python using Scikit-Learn
Wondered how Google comes up with movies that are similar to the ones you like? After reading this post you will be able to build one such recommendation system for yourself. Now you might be thinking "That's interesting. But, what are the differences between these recommendation engines?". Let me help you out with that.
'Love at first sight': Remembering Andre Previn's musical genius
To the editor: I first saw Andre Previn at the Hollywood Bowl in 1965, and it was love at first sight. I remember going backstage after the concert, where it was crowded with movie stars -- but the autograph I wanted was Previn's. I still have the album of his jazz variations on the "My Fair Lady" score that he signed for me so many years ago. I saw Previn many times at the Hollywood Bowl after that, especially while he was music director of the Los Angeles Philharmonic in the late 1980s. I remember so well Previn conducting Rachmaninoff's Piano Concerto No. 2, Grieg's Piano Concerto in A minor and Gershwin's Concerto in F from the keyboard.
Welcome to the Deepfake Universe โ FutureSin โ Medium
In 2019 we live in a world where Deepfake videos and even images of people can be created by AI that are totally manufactured. Meanwhile OpenAI's GPT-2 is being hyped for its ability to write convincingly and deceptively. In this new world AI can mimic human content in a variety of ways while potentially being used by bad actors and state-sponsored propaganda campaigns to influence public sentiment in a variety of ways. In February 2019, we are witnessing an explosion of deception online. In an era when even Facebook refuses to be called a Media company, what exactly are deepfakes?
