recurrent is a Python library typically used in Artificial Intelligence, Natural Language Processing applications. recurrent has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can install using 'pip install recurrent' or download it from GitHub, PyPI.

Recurrent is a python library for natural language parsing and formatting of dates and recurring events. It turns strings like "every tuesday and thurs until next month" into RFC-compliant RRULES, to be fed into a calendar api or python-dateutil's rrulestr. It will also accept such rrules and return a natural language representation of them.

            Issue with portion size of valves
            Asked 2022-Feb-10 at 07:07

            I am having an issue with setting the portion size of a valve during run time. It appears to always take the values placed in the 'Properties' input boxes as its first/initial portion size. I want to have this value read in from a database during start up (ie. In Main > On Start up).

            Attempt 1

            If I assign the value that I read in from the database to a variable "parcel_size" and I place the variable name "parcel_size" in the PortionSize input, it tells be that the PortionSize cannot be zero. I assume that means it is trying to assign the value before I read it in from the database. If I give the varaible "parcel_size" a default value, it just takes that value as the first Portion Size.

            Attempt 2

            I also tried putting in a numerical value in the PortionSize input and then assigning a value during Main > On Start up using:

            To set this from the DB you need to have code like the following for the value

            I tested this and it worked.

            Since the parameter is a static parameter - which you can see when you hover the little icon next to the parameter

            This means that this value is evaluated once, during creation and never again.

            If you want to change during runtime you will need to call valve.set_portionSize(value) if you want to change the value during model execution.

            The root cause for this behavior is not clear, however it seems it's related to the namespace. Pulling the docker image within another namespace works fine. Same works if one deploys the application in a new namespace.

            Alternatively you can also delete the ns completely and then re-create it.

            How to reproduce Keras SimpleRNN behaviour

            I'm trying to learn how keras.layers.SimpleRNN works by following a relatively straightforward tutorial (https://machinelearningmastery.com/understanding-simple-recurrent-neural-networks-in-keras/). However, this tutorial assumes the input is scalar, and I've been unable to scale this to higher-dimensional inputs. Here is my attempt to reproduce the behaviour of a simple RNN with 1x2 input for 3 time steps:

            The matrix multiplications are correct, but they need to be performed at every timestep. And if return_sequences=False Keras returns the output of the last timestep of shape ( 1 , 4 ). So, we can create a for-loop which can perform the matrix multiplications for 3 timesteps.

            Note: The input shape ( 3 , 2 ) denotes ( time_steps , num_features )

            First, I suggest you read Tensorflow's tutorial on time series forecasting. I played around a bit with your code and the data provided. The first important thing is that only the temperature column contains information. In the code below, I prepare the data so that X over a time window of 96 samples/steps and the next step is in Y. X is of dimension (n_samples, 96, 1) and Y of dimension (n_samples, ), I use only steps_backwards points for the past (and discarded the future for simplicity, without affecting the generality) I have tried different models (a simple Fully Connected or RNN + FC, etc.). I'm doing mean pooling (with the functional API rather than the sequential model definition approach) so that I have a single predicted value at the end.
