Reinforcement Learning (RL) is a type of machine learning algorithm that trains algorithms based on a mechanism in which certain actions are associated with certain rewards.
Reinforcement Learning comes into play when there is no hard-coded method for performing a task, but rather there are some set of rules that need to be followed in order for a model to achieve its desired objectives. Reinforcement Learning as a machine learning algorithm models how humans learn and has been predicted as being pivotal in attaining Artificial General Intelligence in AI-based applications, like generating handwriting images.
With Anaconda initiated on your Alibaba Cloud ECS Console and Jupyter Notebook instance ready for Keras, you can build and train the reinforcement learning model.
RELU; 3) add the decoding layer and specify your activation function as
SIGMOID; 4) define your auto-encoder model, compile it and fit to your train dataset; 5) use the model to rebuild the handwritten digits; 6) analyze the loss and accuracy for each epoch; 7) verify your results.
As showed above, with the Auto-encoders Reinforcement Learning technique, you can generate an entirely new handwriting image close to the original one.

Machine vision, or computer vision, is a popular research topic in artificial intelligence (AI) that has been around for many years. However, machine vision still remains as one of the biggest challenges in AI. In this article, we will explore the use of deep neural networks to address some of the fundamental challenges of computer vision.
A Generative Model is used to learn the distribution of the data (image) or sample a new image from its distribution. Generative models can be used in super-resolution reconstruction, image coloring, image conversion, generating images from text, learning hidden representatives of an image, half-supervised learning, and more. Furthermore, generative models can be combined with reinforcement learning for use in simulation and inverse reinforcement learning.
In this blog, we will look at the various types of machine learning methods and explore why businesses need machine learning.
In general, machine learning algorithms can be classified as either "supervised" or "unsupervised" learning. The term "supervise" here does not refer to human intervention but rather the existence of a training dataset with the "correct" values for the machine to learn from. We can further categorize machine learning methods based on its purpose and the system it is applied to: Supervised Learning, Unsupervised Learning, Semi-supervised Learning and Reinforcement Learning.
Reinforcement Learning: Although similar to supervised learning, reinforcement learning is focused on maximizing rewards rather than just getting "correct" answers to a problem. This method helps to incorporate machine learning into gaming, robotics, and navigation. Algorithms discover the next point of action through trial and error and decide which actions yield the greatest rewards. Reinforcement learning comprises of three primary components:
This document introduces a method of image recognition using deep learning frameworks. This method can be applied to scenarios such as illicit image filtering, facial recognition, and object detection.
This guide creates an image recognition model using the deep learning framework TensorFlow in Alibaba Cloud Machine Learning Platform for AI. The entire procedure takes about 30 minutes to complete. After the procedure, the system is able to recognize the bird in the following image.
