چکیده
We introduce the underlying concepts which give rise to some of commonly used machine learning methods, excluding deep-learning machines and neural networks. point their advantages, limitations potential use in various areas photonics. The main methods covered include parametric non-parametric regression classification techniques, kernel-based support vector machines, decision trees, probabilistic models, Bayesian graphs, mixture Gaussian processes, message passing visual informatics.

Towards Principled Unsupervised Learning
General unsupervised learning is a long-standing conceptual problem in machine learning. Supervised learning is successful because it can be solved by the minimization of the training error cost function. Unsupervised learning is not as successful, because the unsupervised objective may be unrelated to the supervised task of interest. For an example, density modelling and reconstruction have of...
متن کاملEfficient Principled Learning of Thin Junction Trees
We present the first truly polynomial algorithm for PAC-learning the structure of bounded-treewidth junction trees – an attractive subclass of probabilistic graphical models that permits both the compact representation of probability distributions and efficient exact inference. For a constant treewidth, our algorithm has polynomial time and sample complexity. If a junction tree with sufficientl...
متن کاملPrincipled Methods for Advising Reinforcement Learning Agents
An important issue in reinforcement learning is how to incorporate expert knowledge in a principled manner, especially as we scale up to real-world tasks. In this paper, we present a method for incorporating arbitrary advice into the reward structure of a reinforcement learning agent without altering the optimal policy. This method extends the potentialbased shaping method proposed by Ng et al....
متن کاملPrincipled Option Learning in Markov Decision Processes
It is well known that options can make planning more efficient, among their many benefits. Thus far, algorithms for autonomously discovering a set of useful options were heuristic. Naturally, a principled way of finding a set of useful options may be more promising and insightful. In this paper we suggest a mathematical characterization of good sets of options using tools from information theor...
متن کاملA Principled Approach to Context-Aware Machine Translation
This paper presents a new principled approach to context-aware machine translation. The proposed approach reformulates the posterior probability of a translation hypothesis given the source input by incorporating the source-context information as an additional conditioning variable. As a result, a new model component, which is referred to as the context-awareness model, is added into the origin...
