            Ag-grid React column shifts that uses valueGetter when rowData fetched from server
            Asked 2021-Jun-11 at 14:48

            Whenever I fetch data from any server to display it in ag-grid, ag-grid does not maintain the column order for the column that uses valueGetter to choose the value and puts that column automatically at the end.

            Since the column does not have a field supplied, I'd recommend either supplying a field or colID to the column. This would be the simplest approach without having to use any API calls to move the column:

            That's because holding all elements of your dataset in the buffer is expensive. Unless you absolutely need perfect randomness, you should use a smaller buffer_size. All elements will eventually be taken, but in a more deterministic manner.

            This is what's going to happen with a smaller buffer_size, say 3. The buffer is the brackets, and Tensorflow samples a random value in this bracket. The one randomly picked is ^

            Training sound classifier on device
            Asked 2021-Jun-02 at 18:52

            I'm trying to train a CoreML sound classifier on device, on iOS, and I have been struggling to find learning resources on the topic. The sound classifier is used to determine whether a snippet of music is similar to a collection of other songs. Hence the output of the classifier is just a label of either "match" / "no match".

            It is so simple to train with the CreateML app workflow. I am simply trying to get the same kind of training on device in iOS, but as far as I know (please correct me if I'm wrong) iOS doesn't support createML.

            I have been trying to adapt code from various source to get this to work in an iOS playground. I can only find resources on training image classifiers, these two have been the most helpful (1, 2).

            Please see the code that I have come up with so far below.

            You probably have to check every point against every other point whether the distance is less than your threshold. So, create a table with all these points, the vector between them and plot them with vectors. The following example creates some random points with random sizes and random colors.

            How to separate JSON fetch data into different divs
            Asked 2021-May-12 at 21:47

            I have javascript to fetch json information. I will be storing this json file locally (I downloaded an example file and added birthdate object for my use example from https://jsonplaceholder.typicode.com/users)

            I am trying to parse the returned JSON information and post the contents into 2 seperate div's. I have a json object named "birthdate". In my script, I have a var set to call today's date named "today". It prints the date as "05-12" in console, and that is how I have the "birthdate" formatted in JSON as well. I don't need the year or time.

            What I would like is to have the script compare "today" with the json object "birthdate". If today = birthdate, then I would like to have that entry information displayed in the user-list-today div to appear under the Birthday Today section of the page.

            If today does not equal birthdate, I would like to have all other entries displayed in the user-list-future div to appear under the Birthday Future section of the page.

            Nothing should be posted in both areas, only one or the other.

            Any help that anyone could provide would be greatly appreciated. I will include all of my code below. The snippet may give error because I have local path to JSON file instead of online version.

            ANSWER

            Answered 2021-May-12 at 11:57

            This has nothing to do with Python or requests.get and little to do with URL formats. It's the service that decides how to parse that URL and how to map its elements.

            • In the first case https://jsonplaceholder.typicode.com/users/1 is treated as a single resource identifier (which it is) so the service returns a single object serialized as JSON. In JavaScript objects are dictionaries. What you posted is a single object, not nested dictionaries

            • In the second case, https://jsonplaceholder.typicode.com/users?id=1it treats the URL as a query on the Users resource with a filter id=1 so it returns an array of objects, even though there's only a single matching object.

            JSONPlaceholder's docs explain that this syntax is used for filtering:

            Filtering resources

            Basic filtering is supported through query parameters.

            Another service could decide that since id is a key, it should return a single object instead of an array. Or it could use a different query string, using eg filter to explicitly specify filter parameters

            There's no standard for either case. While it's a common convention especially in REST-like APIs to include an object's ID in the URL path, there's no single standard or even convention for queries. Each service uses its own format.

            GraphQL (from Facebook) and OData (from Microsoft) are two common query and manipulation protocols. They're a lot more complex than the very simple filtering used by JSONPlaceholder though

            Technically the input will be 1D, but that doesn't matter.

            The internal architecture of your neural network will take care of recognizing the different words. You could for example have a convolution with a stride equal to the embedding size.

            You can flatten a 2D input to become 1D and it will work fine. This is the way you'd normally do it with word embeddings.

            How to get the feature maps from each layers of a trained model during inference time?

            If I understand your question properly, you want to get output feature maps of each layer of a model. Normally, as we mentioned in the comment box, a model with one (or multiple) inputs and one (or multiple) outputs. But in order to inspect the activation feature maps of inside layers, we can adopt some strategies. Some possible scenarios: (1). Want to get output feature maps of each layer in run-time or training time. (2). Want to get output feature maps of each layer in the inference time or after training. And as you quoted:

            I am now running an image through the trained network and want to get the network output (feature maps etc.) at every stage.

            That goes to number 2, get the feature maps in inference time. Below is a simple possible workaround to do this. First, we build a model, and then after training, we will modify the trained model to get feature maps of each layer within it (technically creating the same model with some modification).
