The MIDAS (Modular Integrated Distributed Analysis System) is a system for online analysis of streaming signals and allows easy integration of machine learning frameworks and processing modules. MIDAS aims to simplify the process of setting up of ad hoc networks for online processing and analysis of multiple signals. This is achieved through a distributed structure consisting of nodes and dispatchers. Core features of MIDAS include automatic discovery of network components and easy extensibility with custom nodes. Possible use cases include implementation of real-time signal fusion and machine learning. MIDAS is written in Python 3. For more information (background, installation, usage, ...) refer to the MIDAS wiki. This repository only contains the core library used to setup a MIDAS network. For practical examples of processing nodes please check out the MIDAS-nodes repository.

            There are several things wrong with your code. For example, you're checking for a classname called active-slide, but nothing in your code sets a class with that name. If you're copying and pasting code from other sources without taking some time to understand it, it may be impossible to debug.

            Instead of checking for the existence of a class that doesn't exist, you can instead check for which slide number you're on, and check if you're on the first or last slide. You also need to run this code after slide transitions, not once at the end of your program as you've shown in the Codepen. Here's an example of the working Javascript checking for slideIndex instead of a class:

            The minimum is not a single point but as a rule a larger area. argmin finds the first x and y (top left corner) of this area:

            In case of multiple occurrences of the minimum values, the indices corresponding to the first occurrence are returned.

            What you need is the center of this minimum region. You can find it using moments. Sometimes you have multiple minimum regions for instance in frame107.png. In this case we take the biggest one by finding the contour with the largest area.

            We still have some jumping markers as sometimes you have a tiny area that is the minimum, e.g. in frame25.png. Therefore we use a minimum area threshold min_area, i.e. we don't use the absolute minimum region but the region with the smallest value from all regions greater or equal that threshold.

            Nowcasting Y with known X, using VECM in R
            Asked 2020-Apr-21 at 07:05

            I am trying to nowcast a time series data (Y) using another time series (X) as a predictor. X and Y are cointegrated. Y is a monthly data from Jan 2012 to Oct 2016 and X runs from Jan 2012 to Feb 2017.

            But I can not forecast Y with known X, how it can be made using predict function with a linear regression model. Also, I can not obtain modelled Y (Y hat) values.

            ANSWER

            Answered 2017-Apr-11 at 20:55

            I feel your question is more about how to do nowcasting for cointegrated variables, then let's see later how to implement it in R.

            In general, according to Granger's representation theorem, cointegrated variables can be represented in multiple forms:

            • Long term relationship: contemporaneous values of y and x

            • VECM representation: (diff of) y and x explained by (diff of) lags, and error-correction term at previous period.

            So I am not sure how you would do nowcasting in the VECM representation, since it includes only past values? I can see two possibilities:

            1. Do nowcasting based on the long-term relationship. So you just run standard OLS, and predict from there.

            2. Do nowcasting based on a structural VECM, where you add contemporaneous values of the variables you know (X). In R, you would do this package urca, you need though to check whether the predict function will allow you to add know X values.

            Regarding the long-term relationship approach, what is interesting is that you can obtain forecasts for X and Y based on the VECM (without known X) and from the LT with known X. This gives you a way to have an idea of the accuracy of your model (comparing known and predicted X), which you could use to create a forecast averaging scheme for your Y?

            After updating a signal, call runAsync() to invoke an update. The behavior that you see where the view updates when you hover over it comes from the fact that Vega listens to hover events and invokes an updates.

            How to test if MIDAS.DLL is loaded?
            Asked 2019-Mar-18 at 22:07

            I use Datasnap on Delphi 2007. In a few specific machines when the user try to open the app, he gets the 'Error loading Midas.DLL' error and the app crashes.

            I never could identify in what scenario this occurs, because i always distribute MIDAS.DLL with my apps and this file is always present in the same folder than the app EXE.

            I know i could uses MidasLib to avoid that, but i can't do this because my app uses a cracking protection that crypto the EXE and ends up not being compatible with Midaslib embedded. So Midaslib is not an option for me.

            So what i'm trying to do is to run a small test when the app to check if Midas.DLL is loaded BEFORE the app crashes, so i can be pro-active and register the DLL before the app crashes.

            Delphi determines where to load Midas.Dll from by examining a registry key. Take a look at the source code of CheckDBClient in DSIntf.Pas which should be in your [Delphi\Source\VCL folder.

            You'll see that this CheckDBClient routine generates the exception you are seeing, so there's really no need to check whether Midas.Dll is loaded, though you could use the method Remy suggests in a comment to check the value of the global var DbClientHandle which is initialized (or not) by CheckDbClient.

            CheckDBClient is called via CreateDbClientObject in the call to TCustomClientDataSet.CreateDSBase in DBClient.Pas.

            To fix the error, register Midas.Dll from a command prompt using Delphi's TRegSvr.Exe or Windows' RegSvr32. Or you could register it yourself in your project's start-up code. Delphi comes with the source code of TRegSvr (check your [delphi]\demos\activex folder) so you can see for yourself how it does the registration process.

            Exception User-Unhandled reported in VS Debugger when using Polly
            Asked 2019-Feb-10 at 08:47

            I'm using Polly to catch an exception while calling a Pittney Bowes Geocoder service. I'm using a g1client library that throws a MessageProcessingException. I've wrapped the call in a Polly network policy to retry the call up to 3 times if this exception is thrown, but Visual Studio insists that the exception is "User-Unhandled" What do I need to modify to make this exception be handled? I'm using Visual Studio 2017 community Edition and C# 4.6.1.

            ...

            ANSWER

            Answered 2019-Feb-10 at 08:47

            TL;DR You are just seeing the VS debugger breaking on exceptions.

            You may be understanding the Visual Studio Debugger's (inherently confusing) terminology user-unhandled exception to mean that the executing codebase as a whole is not handling the exception; this is not the case.

            User-unhandled exception in this case means that the exception is first handled other than by your code - here, by the Polly policy.

            First, Visual Studio divides code you are debugging into 'my code' aka 'user code', and 'non-user code'. In your scenario, Polly and the Geocoder library will be classified 'non-user code'.

            Second, by default, the Visual Studio debugger breaks[+] on exceptions handled by 'non-user code' (but using this potentially confusing and alarming term 'user-unhandled'!).

            Visual Studio breaks[+] by default so that you can see the line that triggered the exception as it happened (even if subsequent code will handle it...). So, it sounds (dpdg on debugger settings) as if you are seeing Visual Studio breaking, even though the exception will be handled as configured by the Polly policy. Just press F5/Continue in the debugger, and the subsequent code will resume.

            You can also change this behaviour[+] by following the instructions in this article under the heading Tell the debugger to continue on user-unhandled exceptions.

            You can further satisfy yourself the Polly policy is working by examining the behaviour of the line System.Diagnostics.Debug.WriteLine("Exception being retried" + exception);. You should see output from that line - or see it hit if you set a breakpoint on it - if retries are being invoked.

            Finally, a Polly retry policy rethrows any final exception if all configured retries have been exhausted. This is intentional - to indicate that eventuality - not a failure.

            You correctly have a try { ... } catch (MessageProcessingException ex) { ... } for this, but the debugger may again misleadingly label that final exception 'user-unhandled' - even though you have a try-catch for it - due to its initially being caught by Polly.
