First-order methods for solving quadratic programs (QPs) are widely used for rapid, multiple-problem solving and embedded optimal control in large-scale machine learning. The problem is, these approaches typically require thousands of iterations, which makes them unsuitable for real-time control applications that have tight latency constraints. To address this issue, a research team from the University of California, Princeton University and ETH Zurich has proposed RLQP, an accelerated QP solver based on operator-splitting QP (OSQP) that uses deep reinforcement learning (RL) to compute a policy that adapts the internal parameters of a first-order quadratic program (QP) solver to speed up the solver's convergence rate. The team performed their speed-up on the OSQP solver, which solves QPs using a first-order alternating direction method of multipliers (ADMM), an efficient first-order optimization algorithm. The RLQP strives to learn a policy to adapt the internal parameters of the ADMM algorithm between iterations in order to minimize solve times.

Cassie has made history as the first bipedal robot to complete a five-kilometer (5K) run, having done so in just over 53 minutes. Developed by Oregon State University, the two-legged machine with knees that bend like those of an ostrich, taught itself how to run through a deep reinforcement learning algorithm. Yesh Godse, an undergraduate in the lab, said in a statement: 'Deep reinforcement learning is a powerful method in AI that opens up skills like running, skipping and walking up and down stairs.' Cassie's total time of 53 minutes, three seconds, included about six and a half minutes of resets following two falls. Cassie first stumbled when its computer overheated and the other came after it took a turn at too high of a speed. The robot's makers foresee it eventually delivering packages, managing warehouse tasks and helping people in their homes.

Introduction to Reinforcement Learning

Cassie, a bipedal robot that's all legs, has successfully ran five kilometers without having a tether and on a single charge. The machine serves as the basis for Agility Robotics' delivery robot Digit, as TechCrunch notes, though you may also remember it for "blindly" navigating a set of stairs. Oregon State University engineers were able to train Cassie in a simulator to give it the capability to go up and down a flight of stairs without the use of cameras or LIDAR. Now, engineers from the same team were able to train Cassie to run using a deep reinforcement learning algorithm. According to the team, Cassie teaching itself using the technique gave it the capability to stay upright without a tether by shifting its balance while running.

Four years is a long time in robotics, especially so for a bipedal robot developed at Oregon State University (OSU) named Cassie. Dreamt up as an agile machine to carry packages from delivery vans to doorsteps, Cassie has recently developed an ability to run, something its developers have now shown off by having it complete what they say is the first 5-km (3.1-mi) jog by a bipedal robot. We first took a look at Cassie the bipedal robot back in 2017, when OSU researchers revealed an ostrich-like machine capable of waddling along at a steady pace. It is based on the team's previously developed Atrias bipedal robot, but featured steering feet and sealed electronics in order to function in the rain and snow and navigate outdoor terrain. The team has since used machine learning to equip Cassie with an impressive new skill: the ability to run. This involved what they call a deep reinforcement learning algorithm, which Cassie combines with its unique biomechanics and knees that bend like an ostrich to make fine adjustments to keep itself upright when on the move.

Let's move onto the different types of machine learning. The first type of machine learning we will talk about is supervised learning. In this method, you take a sample from the larger data set. This sample is used to represent the correlation and relationships that can be inferred from the data. Basically, it will try to summarize different cases in order to learn what predictions can be made or how to classify data.

Artificial Intelligence (AI) has had the power of ruling the technologically dominated world for quite some time now. Today, we have reached a stage wherein advanced artificial intelligence has become one of the most sought after techniques to bring about innovation and solve complex business problems. Over the last few years, the technology has matured to the extent that it has become highly scalable. In the midst of all this, what has grabbed eyeballs from everywhere across is reinforcement learning – training the machine learning models to be able to make the best possible decisions. Reinforcement learning makes use of algorithms that do not rely only on historical data sets, to learn to make a prediction or perform a task.

For oil and gas companies looking at drilling wells in a new field, the issue becomes one of return vs. cost. The goal is simple enough: install the fewest number of wells that will draw them the most oil or gas from the underground reservoirs for the longest amount of time. The more wells installed, the higher the cost and the larger the impact on the environment. However, finding the right well placements quickly becomes a highly complex math problem. Too few wells sited in the wrong places leaves a lot of resources in the ground.
