May 17, Google has not only helped the data science community with open-source libraries like TensorFlow, but has also been foundational to research and development initiatives outside its organizations.
To further expedite innovation in the data science field, Google has been providing TensorFlow Research Cloud for creative projects to cater to the needs of intensive resources. And today, it has reached seven figures.Intro - Training a neural network to play a game with TensorFlow and Open AI
Just like any other research, accomplishing a breakthrough in machine learning is a challenging task. In fact, innovation in data science is even more difficult due to the requirement of substantial computational resources.
However, researchers can leverage the free resources that Google provides with its Tensorflow Research Cloud to continue the innovation in the domain, while keeping the price in check. Machine learning models require a colossal amount of data to make accurate decisions, thereby requiring exceptional computational power.
As per Google, the cloud-based processing capabilities will support a wide range of computational-intensive projects that might not be possible otherwise. The TPU offers petaflops of performance in a single pod, which is enough to make any research breakthrough. Google has made TPUs precisely to render massive multiplications and additions for neural networks while consuming less power.
However, to access the resources, you will need approval from Google. A researcher will have to sign up by providing details of the projects, which would help the firm evaluate based on the creativity and potential of the initiative. Google will then choose a few projects and allocate the computation needs accordingly.
The program by Google is not limited to academia — anyone with an interest in research can apply. With this, Google is trying to encourage a wide range of experts, even those with a non-traditional background, to apply. Besides, one can apply multiple times with different projects. The idea behind this program is to benefit the open machine learning research community as a whole, and thereby, applicants are expected to release their source-code, publish the work for peer-review, among others.
However, this is limited to businesses interested in proprietary research and development. This will help companies train models in days — or even hours — instead of weeks. Cloud TPU can be used for processing industrial-scale datasets such as image, videos, and audio, while making live requests in production using large and complex ML models. And ever since, it has continued to support research due to the increasing demand for computation. Not all researchers or AI enthusiasts can afford something closer to what these solutions were consuming.

Google’s TensorFlow Lite Model Maker adapts state-of-the-art models for on-device AI
Latest commit.Google today announced TensorFlow Lite Model Makera tool that adapts state-of-the-art machine learning models to custom data sets using a technique known as transfer learning. Tools like Model Maker could help companies incorporate AI into their workflows faster than before.
Essentially, Model Maker applies models trained on one task to another related task at varying levels of accuracy, according to several parameters specified at the outset. Model accuracy can be improved with Model Maker by changing the model architecture, which requires editing one line of code. After the input data specific to an on-device AI is loaded in, Model Maker evaluates the model and exports it as a TensorFlow Lite model.
Models created by TensorFlow Lite Model Maker have metadata attached to them, including machine-readable parameters like mean, standard deviation, category label files, and human-readable parameters such as model descriptions and licenses. Google notes that fields like licenses can be critical in deciding whether a model can be used, while other systems can use the machine-readable parameters to generate wrapper code.
In the coming months, Google intends to enhance Model Maker to support more tasks, including object detection and several natural language processing tasks. The launch of Model Maker follows on the heels of an API — Quantization Aware Training QAT — that trains smaller, faster TensorFlow models with the performance benefits of quantization the process of mapping input values from a large set to output values in a smaller set while retaining close to their original accuracy.

Is this a controversial opinion? There is a difference between Artificial intelligence and Artificial behavior. We do not want the agents in our games to outsmart players. The opponent needs to be imperfect, imitating a human-like behavior. Games are not only entertainment, though. Training a virtual agent to outperform human players, and to optimize its score, can teach us how to optimize different processes in a variety of different and exciting subfields.
In this article, we will see how to develop an AI agent able to learn how to play the popular game Snake from scratch. This approach consists in giving the system parameters related to its state and a positive or negative reward based on its actions. No rules about the game are given, and initially, the agent has no information on what it needs to do. The goal for the system is to figure it out and elaborate a strategy to maximize the score — or the reward. We are going to see how a Deep Q-Learning algorithm learns to play Snake, scoring up to 50 points and showing a solid strategy after only 5 minutes of training.
For the full codeplease refer to GitHub repository. Below I will show the implementation of the learning module. The game was coded in python with Pygame, a library which allows developing fairly simple games. On the left, the agent was not trained and had no clues on what to do whatsoever. The game on the right refers to the game after iterations about 5 minutes. The highest score was 83 points, after iterations.
How to teach AI to play Games: Deep Reinforcement Learning
Reinforcement Learning is an approach based on Markov Decision Process to make decisions. The system will then try to learn how to predict targets based on unseen inputs. In Reinforcement Learning, we have two main components: the environment our game and the agent our Snake.It also gave me an opportunity to build something non-trivial using machine learning techniques, and my background in games made an interactive demo a good fit.
NeuroBlast is a vertically scrolling space shooter where you control a ship that tries to defeat increasing waves of enemies. Normally, these enemies fly in predefined formations, with predefined firing patterns, and come in waves. The big difference in NeuroBlast is that the enemies use machine learning to determine what their firing pattern should be. To demonstrate what you can do with the tools available, we decided to build a Neural Network to drive the behaviour of the enemies in the game, and we built it using the popular Keras library using the TensorFlow backend.
Plus, by using ActivePython to develop our game, we could leverage the Intel MKL optimizations compiled into the latest release so anything that uses certain core math functionality, eg. NumPy, would get a big speed-up out of the box. Our Neural Net is ultimately a very simple one — four inputs and a single output neuron. It will use supervised learning to do binary classification on a simple problem: was each shot a hit or a miss? It utilizes the delta between player and enemy position, and player and enemy velocity as the inputs.
When building the network, I initially had only a single hidden layer with 4 nodes but found that after training it, it was somewhat erratic. I experimented with a few different configurations, and ultimately settled on the one we used for the demo. What appealed to me though was that even with a very small amount of training data, and regardless of how you trained it, it would consistently settle into a similar behaviour pattern which made it great for a floor demo where anyone could play or train the game.
The visualization was cobbled together by myself to run inside PyGame natively. I had to implement it natively in PyGame because a traditional plotting library like matplotlib was just too slow. This meant that there was a really wide variation between the values in the input and I found that the network would just not really converge to a consistent behaviour.
So, I normalized the input data to be roughly between 0. So, lesson for you kids: normalize your input data! Once the network is trained, when you play the game, every instance of an enemy spaceship uses its own instance of the neural network to make decisions about when it should fire.
Keras makes the setup and evaluation of neural nets extremely simple and the ability to choose between Theano or Tensorflow for the backend makes it very flexible. Tip : I used Keras 2. During gameplay, the enemies each evaluate this NN every frame to determine whether they should be shooting at the player, again with only a single line of code:.
Ultimately I would like to push this to GitHub as I had a number of requests at PyCon to do so and would love to see others learn from this project.
