About this course: Probabilistic graphical models (PGMs) are a rich framework for encoding probability distributions over complex domains: joint (multivariate) distributions over large numbers of random variables that interact with each other. They are also a foundational tool in formulating many machine learning problems. It describes the two basic PGM representations: Bayesian Networks, which rely on a directed graph; and Markov networks, which use an undirected graph. The course also presents some important extensions beyond the basic PGM representation, which allow more complex models to be encoded compactly.

Inference Engine It accepts and promotes human interpretation by making fuzzy inference according to inputs and IF-THEN rules. A number of other concepts are associated with fuzzy logic such as fuzzy set theory, fuzzy modelling, the fuzzy control system that have been developed for further enhancement. In control systems theory, if the fuzzy interpretation of the problem is appropriate and if the fuzzy theory is developed precise and correct, then fuzzy controllers can be accordingly designed and they work quite well to their advantages. Most of the fuzzy logic control systems are knowledge-based systems which mean either their fuzzy models or their fuzzy logic controllers are described by fuzzy logic IF-THEN rules.

Now I could have said: "Well that's easy, MCMC generates samples from the posterior distribution by constructing a reversible Markov-chain that has as its equilibrium distribution the target posterior distribution. Unfortunately, to directly sample from that distribution you not only have to solve Bayes formula, but also invert it, so that's even harder. If you can't compute it, can't sample from it, then constructing that Markov chain with all these properties must be even harder. The surprising insight though is that this is actually very easy and there exist a general class of algorithms that do this called Markov chain Monte Carlo (constructing a Markov chain to do Monte Carlo approximation).

So, it is very important to predict the loan type and loan amount based on the banks' data. In this blog post, we will discuss about how Naive Bayes Classification model using R can be used to predict the loans. As there are more than two independent variables in customer data, it is difficult to plot chart as two dimensions are needed to better visualize how Machine Learning models work. In this blog post, Naive Bayes Classification Model with R is used.

Logistic Regression is a powerful statistical way of estimating discrete values (usually binary values) from a set of independent variables. The Naïve Bayes Classifier Theorem works on the popular Bayes Theorem of Probability. K-means clustering algorithm is a popularly used unsupervised machine learning algorithm for cluster analysis. Support Vector Algorithm is a supervised machine learning algorithm where raw data is plotted in the n-dimensional plane.

In the last few months, I have had several people contact me about their enthusiasm for venturing into the world of data science and using Machine Learning (ML) techniques to probe statistical regularities and build impeccable data-driven products. Machine Learning theory is a field that intersects statistical, probabilistic, computer science and algorithmic aspects arising from learning iteratively from data and finding hidden insights which can be used to build intelligent applications. There are many reasons why the mathematics of Machine Learning is important and I'll highlight some of them below: The main question when trying to understand an interdisciplinary field such as Machine Learning is the amount of maths necessary and the level of maths needed to understand these techniques. Some of the fundamental Statistical and Probability Theory needed for ML are Combinatorics, Probability Rules & Axioms, Bayes' Theorem, Random Variables, Variance and Expectation, Conditional and Joint Distributions, Standard Distributions (Bernoulli, Binomial, Multinomial, Uniform and Gaussian), Moment Generating Functions, Maximum Likelihood Estimation (MLE), Prior and Posterior, Maximum a Posteriori Estimation (MAP) and Sampling Methods.

Since Naive Bayes is a probabilistic classifier, we want to calculate the probability that the sentence "A very close game" is Sports, and the probability that it's Not Sports. Just count how many times the sentence "A very close game" appears in the Sports category, divide it by the total, and obtain . Then, calculating means counting how many times the word "game" appears in Sports samples (2) divided by the total number of words in sports (11).

This paper proposed a "PixelGAN Autoencoder", for which the generative path is a convolutional autoregressive neural network on pixels, conditioned on a latent code, and the recognition path uses a generative adversarial network (GAN) to impose a prior distribution on the latent code. PixelGAN Autoencoder The key difference of PixelGAN Autoencoder from the previous "Adversarial Autoencoders" is that the normal deterministic decoder part of the network is replaced by a more powerful decoder -- "PixelCNN". Figure 2 shows that PixelGAN Autoencoder with Gaussian priors can decompose the global and local statistics of the images between the latent code and the autoregressive decode: Sub-figure 2(a) shows that the samples generated from PixelGAN have sharp edges with global statistics (it is possible to recognize the number from these samples). This paper keeps this advantage and modifies the architecture as follows: The normal decoder part of a conventional autoencoder is replaced by PixelCNN proposed in paper Conditional Image Generation with PixelCNN Decoders [2].

AMIDST provides tailored parallel (powered by Java 8 Streams) and distributed (powered by Flink or Spark) implementations of Bayesian parameter learning for batch and streaming data. Dynamic Bayesian networks: Code Examples includes some source code examples of functionalities related to Dynamic Bayesian networks. FlinkLink: Code Examples includes some source code examples of functionalities related to the module that integrates Apache Flink with AMIDST. As an example, the following figure shows how the data processing capacity of our toolbox increases given the number of CPU cores when learning an a probabilistic model (including a class variable C, two latent variables (dashed nodes), multinomial (blue nodes) and Gaussian (green nodes) observable variables) using the AMIDST's learning engine.
