12 Companies Using Machine Learning in Cool Ways

Cool Machine Learning Applications

Starting with Quora…

How Quora Uses Machine Learning?

For Ranking Answers [Quora] – Quora uses linear regression, logistic regression, random forests, gradient boosted trees, neural networks. In particular, gradient boosted trees and some deep learning approaches. They also use other factors like number of upvotes, the previous answers written by the author, etc.

To Store Data: Quora use MySQL to store critical data such as questions, answers, upvotes, and comments. Data size stored in MySQL is of the order of tens of TB without counting replicas. Our queries per second are in the order of hundreds of thousands. As an aside, we also store a lot of other data in HBase.

Over the years, MySQL usage at Quora has grown in multiple dimensions including the number of tables, table sizes, read QPS (queries per second), write QPS, etc. In order to improve performance, we implemented caching using Memcache as well as Redis.

To combine questions: The company uses Natural Language processing to combine questions with exact same wording/almost similar intended meaning. You can see it’s efficiency by observing so many similar questions out there.

Other Platforms and Tools: According to a software engineer at Quora, these are the tools and platforms quora uses to build containers, export logs, cluster building, etc

  • Amazon EKS helped them to get off the ground quickly without having to worry about etcd
  • Terraform enables them to manage EKS clusters and associated AWS resources using code
  • They use Skaffold as a common tool for local development and deployment to production
  • BuildKit helps them with smart and concurrent in-cluster builds
  • Prometheus helped them to perform well for collecting and providing time series metrics

How Twitter Uses Machine Learning?

Machine Learning at Twitter: At Twitter, we use machine learning (ML) models in many applications, from ad selection, to abuse detection, to content recommendations and beyond.

For example, Every second on Twitter, ML models are performing tens of millions of predictions to better understand user engagement and ad relevance.

In a social network like Twitter, when a person joins the platform, a new node is created. When they follow another person, a follow edge is created. When they change their profile, the node is updated. This stream of events is taken by an encoder neural network that produces a time-dependent embedding for each node of the graph. The embedding can then be fed into a decoder that is designed for a specific task like predicting future interactions by trying to answer various questions.

How Apple Uses Machine Learning?

Speech Recognition [Apple’s Siri] – Siri was using multivariate gaussian mixture models (GMM’s) till 2011, replaced by hidden Markov Models (HMM’s) till 2014, and updated it with Long Short Term Memory Networks from 2014 till now. “Hey Siri” detector uses a Deep Neural Network (DNN) to convert the acoustic pattern of your voice at each instant into a probability distribution over speech sounds.

The giant unicorn has introduced a scale-invariant convolution layer and used it as the main component of their tempo-invariant neural network architecture for downbeat tracking. This helps company to achieve higher accuracy with lower capacity compared to a standard CNN.

Few months ago, Apple has presented a meta-learning framework under which the labels are treated as learnable parameters, and are optimized along with model parameters. The learned labels take into account the model state, and provide dynamic regularization, thereby improving generalization. They considered two categories of soft labels, class labels specific to each class, and instance labels specific to each instance. In case of supervised learning, training with dynamically learned labels leads to improvements across different datasets and architectures. In presence of noisy annotations in the dataset, their framework corrects annotation errors, and improves over the state-of-the-art.

How Snapchat Uses Machine Learning?

For Face Detection and Filters [Snapchat] – In a research paper, published on Arxiv, the company seems to detail one of its tricks for compressing crucial image recognition AI while still maintaining acceptable performance. This image recognition software and algorithms like Viola-Jonesare used by the company for Face Detection. To get the facial features and apply filters accordingly, Snapchat uses Active Shape Models and Image Processing.

Ads Recommendation: Exactly what stories end up at the top of your newsfeed depends a lot on how you use Snapchat. And with every swipe and tap, the A.I. learns a little more. Snap then turns that data into something it can sell to people who make Snap stories, who want to make sure the effort they put into making stories turns into clicks.

“Search surfaces interesting Stories created by machine learning and allows our community to find Stories for anything they might be interested in,” Spiegel said, CEO of Snap.

Along with that, Snap’s algorithm pays attention to whether you have a preference for certain published stories, and then starts to prefer to show you those publishers.

How DeepMind Uses Machine Learning?

Algorithm used in AlphaGo – AlphaGo combines machine learning and advanced tree search with deep neural networks. These neural networks take a description of the Go board as an input and process it through 12 different network layers containing millions of neuron-like connections. One neural network, the “policy network,” selects the next move to play. The other neural network, the “value network,” predicts the winner of the game. So, this is about Alpha Go. Let’s talk about AlphaGo Zero (A version of AlphaGo Zero).

AlphaGo Zero: AlphaGo Zero’s neural network was trained using TensorFlow, with 64 GPU workers and 19 CPU parameter servers. Only four TPUs were used for inference. The system starts off with a neural network that knows nothing about the game of Go. It then plays games against itself, by combining this neural network with a powerful search algorithm. As it plays, the neural network will be active and it start predicting next moves as well as the eventual winner of the games. Hey wait, Another version is also their (AlphaGo Zero) but its similar to this one but with more powerful training and its the most advanced version till yet)

How Facebook Uses Machine Learning?

Detection and Interpretation [Facebook] – Facebook uses DeepText, a text understanding engine, to automatically understand and interpret the content and emotional sentiment of the thousands of posts (in multiple languages) that its users publish every second.

Tulloch, An AI researcher at Facebook says that the company uses an NLP system built around neural networks to identify posts that are excessively promotional, spam or clickbait. The deep learning model filters these types of posts out and keeps them from showing in users’ news feeds. Outside of the news feed, deep learning models are helping Facebook develop products by enabling developers to understand content at a large scale.

How Google Uses Machine Learning?

Google – The search engine that is powered by AI [Google] – According to Wired’s Cade Metz; Google’s search engine was always driven by algorithms that automatically generate a response to each query. But these algorithms amounted to a set of definite rules. Google engineers could readily change and refine these rules. And unlike neural nets, these algorithms didn’t learn on their own. But now, Google has incorporated deep learning into its search engine. And with its head of AI taking over search, the company seems to believe this is the way forward.

Just take a look at below given image. It shows how deeply AI in integrated in most of the Google products.

Companies Using Machine Learning In Cool Ways

ML in Google Products: Google Ads and Doubleclick both incorporate Smart Bidding which is a machine learning powered automated bidding system. Google Chrome uses AI to present short and highly related parts of a video while searching for something in Google Search. And it also uses artificial intelligence to analyze the images on a website and plays an audio description or the alt text (when available) for people who are blind or have low vision.
