hierarchical temporal memory implementation in golang. this is a direct port of the spatial & temporal poolers, temporal memory, and encoders as they currently exist in numenta’s nupic project. this project was done as a learning exercise, no effort has been made to optimize this implementation and it was not designed for production use. the nupic project basically demonstrates the cla, a single stage of the cortical hierarchy. eventually this same code can be extended to form a full htm hierarchy. ##changes from numentas implementation * temporal pooler ephemeral state is stored in strongly typed struct rather than a hashmap. t-1 vars have "last" appended to their names. * temporal pooler params

            Create a Space Adjacency Matrix in ggplot
            Asked 2022-Apr-12 at 00:35

            I wish to create a Space Adjacency Matrix in R, preferably using ggplot/tidyverse for consistency with other scripts, but I am open to other solutions.

            Here is what I am looking for.

            A Space Adjacency Matrix is used in interior and architectural design to illustrate relationships (adjacencies) between spaces within a building.

            Each space in the building has a relationship (or lack of relationship) to every other space.

            AzureStaticWebApp@0 push from artifacts
            Asked 2022-Mar-31 at 18:11

            I've a CD pipeline that builds a project (multiple times for different environments) and publishes / saves the ./dist directories as one stage. I can download each environment and run locally as expected.

            Each environment build is a stage that needs a manual approval. This is where I am getting lost. Each stage shows the correct artifact being pulled into the stage BUT the AzureStaticWebApp@0 -> app_location input results in a "Could not detect this directory." error.

            To recap: After building the project and saving as an artifact (I can manually download and verify) I am unable to push that built code to Azure Static Web App as it cannot be found. I've tried any number of combinations to no effect. Any advice?

            I'm using templates, here is the Push Built Project to Azure Static Web Apps template

            app_location specifies the root of your application code. The property should point to a location in your repo.

            How to do N-Point circular convolution for 1D signal with numpy?
            Asked 2022-Feb-09 at 20:03

            I want a circular convolution function where I can set the number N as I like.

            All examples I looked at like here and here assume that full padding is required but that not what I want.

            I want to have the result for different values of N

            • so input would N and and two different arrays of values
            • the output should be the N point convolved signal

            Here is the formula for circular convolution. Sub N can be seen as the modulo operation.

            taken from this basic introduction


            update for possible solution

            This answer is a suitable solution when the array a is piled accordingly to the different cases of N.

            When I find time I will post a complete answer, meanwhile feel free to do so.

            • It's specific to Excel, so I don't know how these results will carry over to Access and other Office programs.
            • It's just a test of a variety of cases. A definitive answer would be based on knowledge of the algorithms used to calculate IsEmpty(), VarType, and TypeName(), and to assign Empty.

            .net6 & MoreLinq : Call is ambiguous between System.Linq.Enumerable.DistinctBy and MoreLinq.MoreEnumerable.DistinctBy
            Asked 2022-Jan-17 at 09:00

            Recently I upgraded one of my projects to use .NET 6. Earlier I was using MoreLinq library to use DistinctBy() to apply it on the specific property.

            Now as I upgraded TargetFramework to .NET 6, this change come up with inbuilt support to DistinctBy().

            Now the compiler is confused about which DistinctBy() needs to select, I can't rely on System.Linq, because the removal of using MoreLinq will cause multiple other errors.

            I know if we face ambiguity between the same methods then we can use using alias, but I am not sure how to use using alias for Linq extension methods.

            You can't alias an extension method, but you can call the extension like a normal method, using the full namespace. After all, extension methods are really just syntactic sugar. For example (using the same data you provided in your fiddle):

            Using the CGA/EGA/VGA planar graphics modes
            Asked 2022-Jan-17 at 01:56

            I have trouble to grasp how to use colors in CGA/EGA/VGA video graphics modes. The video modes I'm particularly interested in are 0Dh (EGA 320x200) and 12h (VGA 640x480). Both of these modes have 4 planes, thus 16 colors.

            My (probably incorrect) understanding is that I should activate a set of planes by writing a bitmask to port 03C4h, then when I write to video memory, the data only gets written to the activated planes. Mostly I used this document to get my information, though I also encountered several other tutorials and discussions: http://www.techhelpmanual.com/89-video_memory_layouts.html

            Now I'm trying to write pixels in all possible colors in the first word in the video memory (top left part of screen). I load 1 for the initial bitmask to AH and 1 bit to BX. Then in a loop, I increment AH and shift (SHL) the bit in BX to hit a different pixel next time. I OR BX to A000h:0000h to add each pixels by leaving the already existing pixels untouched.

            What I'm expected to see is a line of pixels in all possible 16 EGA colors on the top left of the screen. What I actually see is 7 white and 1 bright yellow dots with black pixels in between them. What am I doing wrong?

            Also, every tutorial says that I must write 0005h to port 03CEh before I start to use planes. What is the purpose of that? When I comment those lines out, I can still use planes (I mean, in other programs). Previously I had success using planes when I was writing to different words in video memory (so I didn't need different color pixels in one block of 16 pixels that's represented by a single word in video memory); and when I used BIOS functions (e.g. INT 10h/AH=0Ch) to write pixels, but still I want to understand how to use planar graphics without BIOS, as I believe the BIOS functions are slow.

            Here is my code (indentation is optimized for 8-width tabs, so it kind of looks off here):

            Answered 2022-Jan-17 at 01:56

            Writing the word 0005h to ports 03CEh and 03CFh will select write mode 0. This is a complex mode that involves many features of the VGA but luckily for us most of these are reset when the video mode is set.
            However your code still needs to do the following:

            • In order to fill the VGA's internal 32-bit latch, you must perform a read-before-write operation
            • Restricting output to a single or a few pixels is done using the BitMask register.

            MDN Says:

            For example, for any MIME type whose main type is text, you can add the optional charset parameter to specify the character set used for the characters in the data. If no charset is specified, the default is ASCII (US-ASCII) unless overridden by the user agent's settings. To specify a UTF-8 text file, the MIME type text/plain;charset=UTF-8 is used.

            So, for anything based on text/... you can optionally add the charset.
