kandi X-RAY | surreal Summary
Surreal is a Deep Learning based super resolution algorithm. The goal for this project is to provide a generic super resolution algorithm for upscaling images. The first implementation is going to use a conditional DCGAN (Deep Convolutional Generative Adversarial Network) so that the generative model operates on perceptual loss - not some kind of hacky euclidean distance metric. I am reading the papers below but simplifying the model fairly drastically.

QUESTION
I'm currently trying to solve a little problem.
I have the following code. I try to filter and re-render the fetched movielist based on the chosen genre.
So far i am able to cast the selected option to an object in my js-script but i don't know where to go from here. The genre values in my observable array is an array of its own since one movie can have multiple genres.
Here's my script so far:
...ANSWER
Answered 2020-Dec-12 at 01:27You could add a computed observable filteredMoviesList which would go through each of the filters you describe and filter for the selected genre. Then in your html you would just bind your foreach binding to that instead of moviesList. Here is a simple example:

QUESTION
I'm trying to implement Conway's surreal numbers in Scala. A surreal number is defined recursively – as a pair of sets of surreal numbers, called left and right, such that no element in the right set is less than or equal to any element in the left set. Here the relation "less than or equal to" between surreal numbers is also defined recursively: we say that x ≤ y if
- there is no element a in the left set of x such that y ≤ a, and
- there is no element b in the right set of y such that b ≤ x.
We start with defining zero as a pair of empty sets, then use zero to define 1 and -1, and so on.
I cannot figure out how to enforce the definition of a surreal number at compile time. This is what I have now:

Have been out of Swift coding for almost a year, I'm back.
Download Xcode 10 beta. Have I lost my mind? I've tried every trick I know, none of the UI elements show up in storyboard. Zero. The sidebar is empty.

Xcode 9, no problem there they are, all my UI buttons, etc.
thanks, this is kind of surreal. :-)

Answered 2018-Oct-22 at 13:27Library content has moved from the bottom of the Inspector area to an overlay window, which can be moved and resized like Spotlight search. It dismisses once items are dragged, but holding the Option key before dragging will keep the library open for an additional drag.
The library can be opened via:
a new toolbar button (image attached);
the

QUESTION
I've created a DMR Topic model (via Java API) which calculates the topic distribution based on the publication-year of the documents.
The resulting distribution is a bit confusing, because there are a lot of negative propabilities. Sometimes all propabilities for a whole topic are negative values. See:
Q1: Why are there negative values? The lowest possible possibility for a topic distribution for a given feature should be at least 0,0 ... I guess?
Additional I build a LDA model where the ModelLogLikelihood seems to be surreal. I trained the model with nearly 4 million documents and 20 topics. Alpha =1.0 ; Beta = 0.01 ; # iterations 1000;
Results in Model-Log likelihood: -8.895651309362761E8
Q2: Can this value be correct? Or am I doing something wrong?
...ANSWER
Answered 2020-Mar-14 at 18:55Thanks for using DMR! LDA assumes that the prior for the topic distribution for each document is a Dirichlet distribution. The parameters for a K-dimensional Dirichlet are K non-negative real numbers. DMR-LDA generates a document-specific prior based on the properties of a document.
Q1: These are not probabilities, they are regression coefficients. If you have a document with feature 2014, the value for the Dirichlet parameter for topic 1 with the expression exp(-4.5 + -0.25). This is the default parameter plus the offset for 2014, exponentiated to make it non-negative. These values are equivalent to about 0.01 for the default value with no additional features, and 0.008 (78%) for 2014.
Q2: This is a common confusion! The key is that this is a log probability. The log function crosses 0 at 1, since anything to the 0 is 1. The log of any value less than 1 is negative. Since all probabilities are less than or equal to one, all log probabilities are zero or negative. The other thing that often surprises people is how large the log probabilities are. Let's say you have a language model where each word token is independent, and the probability of a given word is usually around 1/1000. The log probability of one word is therefore around -7.0. The joint probability of a whole collection is the product of the token probabilities, so the log of that joint probability is the sum of -7. I'm guessing your collection has about 100M tokens?

Install surreal
You can use surreal like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
