Gradient descent is one of the most popular algorithms to perform optimization and by far the most common way to optimize neural networks. At the same time, every state-of-the-art Deep Learning library contains implementations of various algorithms to optimize gradient descent (e.g. These algorithms, however, are often used as black-box optimizers, as practical explanations of their strengths and weaknesses are hard to come by. This blog post aims at providing you with intuitions towards the behaviour of different algorithms for optimizing gradient descent that will help you put them to use. We are first going to look at the different variants of gradient descent.

During the last fifteen years, a strange parallel economy has covertly developed to the point where it envelops almost all internet users, including you. No money changes hands in this immense network, but it produces enormous transactional benefits nonetheless. In this economy, you labor daily as a trainer, teaching software robots how to perform tasks. In return, the bots then take over much of those tasks for you. You trade your daily labor in exchange for the value produced by the work of your powerful and ubiquitous robot apprentices.

Machine learning software, once thought of as highly technical and complicated, is now widely available. Machine learning, which allows computers to learn from experience without being specifically programmed, heightens an organization's ability to build data-backed applications to enhance the customer experience and make it fully personalized from the first interaction. Well-known e-commerce sites have been using machine learning to advertise and recommend products and services unique to customer profiles, based on buying behavior and browser history. Think about the last time you searched for a product online. Shortly afterward, did you receive advertisements similar to the products you searched for?

What reactions did people have to the movie trailer for Morgan (which was created entirely -- and for the first time -- by an AI bot, and a pretty famous one at that)? Which is a fair reaction. Computers can now write, read, learn and speak. And for some, this is pretty scary -- people are terrified that bots will snatch their jobs and eventually take over the world and render humans useless (films like I, Robot haven't helped this). Many people naturally hold irrational fears.

We cover many emerging markets in the startup ecosystem. Previously, we published posts that summarized Financial Technology, Internet of Things, Bitcoin, and MarTech in six visuals. This week, we do the same with Artificial Intelligence (AI). At this time, we are tracking 855 AI companies across 13 categories, with a combined funding amount of $8.75billion.

Vehicle-to-vehicle communication is critical for the future of the autonomous car. But vehicle-to-infrastructure communication is what will tie everything together. "If we look at it in a very basic level, automated and connected vehicles, to make this happen … it requires an ecosystem to work together," said Tammy Meehan Russell, global portfolio manager for intelligent transportation at 3M. "Very basically that ecosystem is vehicle, human and infrastructure." While visiting the University of Michigan's Mobility Transformation Center in Ann Arbor, our group of reporters was given a tour of Mcity, a testing and training ground for autonomous, automated and self-driving vehicles. Mcity is a 32-acre artificial town built by MTC and opened in July 2015 for the specific purpose of testing autonomous cars in real world conditions. Just about everything an autonomous car might encounter is represented at Mcity: different kinds of roadways (concrete pavement, grooved pavement etc.), different kinds of road signs and lines, various types of traffic signals, highway conditions, urban conditions and so forth.

New York-based Calrifai -- backed by investors including Google Ventures, Lux Capital, and NVidia -- entered the R/GA accelerator this year, after raising $10M in Series A in Q2'15. BI, Sales & CRM: Applications here include voice analytics to extract information from calls, automated customer response solutions, business data analytics, and sales targeting. To name a few, Palo Alto-based Mariana raised $2M in seed money from investors including Blumberg Capital; London-based True AI, previously seed funded by Entrepreneur First, entered the Microsoft Ventures Accelerator in Q3'16; another UK-based startup, Ripjar, raised funds from Winton Ventures in Q2'16. Three startups in the private sector using AI in e-commerce raised funding rounds this year: Reflektion raised $18M in Q1'16 from investors including Intel Capital, Battery Ventures, and Marc Benioff; ViSenze raised $10.5M in Series B from investors including Rakuten Ventures, Enspire Capital, and Phillip Private Equity; India-based Staqu raised angel funds in Q2'16.

Artificial intelligence (AI) in games is often confused with programmed bots (or NPCs). Yes, these bots are "intelligent," so to speak, because they interact with human players, but those interactions are limited by the bots' programming -- they don't behave outside their coding. Conversely, AI applications in games can react to the behavior of human players with their own assessment of the situation -- like in that historic game of Go -- using an algorithm called deep learning. At BlizzCon 2016 on Friday, Google and Blizzard Entertainment announced a partnership to bring Google's deep-learning AI, DeepMind, to StarCraft II. DeepMind will use the real-time strategy game as a testing environment for AI research, using deep reinforcement learning to develop an AI agent that can play StarCraft II effectively.
