algorithm – Matlab mix file simulation result of my genetic model are incorrect

I’m working on a project were I want to generate c code for a motor speed control model using simulink coder. The code has already been generated and some modifications were also did according to what a I want to do: I want to run simulation (executable mix file of code version of the model) … Read more

python – Changing Shape in Image input to Match that of a Downloaded Model

I am working on a Model downloaded from github that takes as an input an image and begins a Classification process . After taking a deeper look at this model,i figured out that it expect image with type (numpy.ndarray ) and a Shape of (1, 512, 512, 1).The model downloaded predicts on a tfrecord file … Read more

r – Checking the homoscedasticity assumption of an lme model

I have the following lme model, which I am running using the following code: IDRTlme <- lme(Score ~ Group*Condition, random = ~1|ID, data=IDRT) I would like to carry out the levene’s test as follows: leveneTest(residuals(IDRTlme) ~ IDRT$Group) Is this the correct way of carrying out a Levene’s test on an lme output? If not, then … Read more

python – Unable to produce visualisations to calculate topic frequency for LSI model

I am trying to create a graph which shows the frequency of the topics for LSI. I was able to do this for my LDA model using the same code. When I try to visualize my LSI topics I get error messages as shown below. The code to create the models is below: # Import … Read more

machine learning – Keras Dense Model ValueError: logits and labels must have the same shape ((None, 200, 1) vs (None, 1, 1))

I’m new in machine learning and I’m trying to train a model. I’m using this Keras oficial example as a guide to set my dataset and feed it into the model: From the training data I have an sliding windows created for a single column and for the labels I have a binary classification … Read more

flutter – Data model failure in dart _TypeError (type ‘_InternalLinkedHashMap’ is not a subtype of type ‘String?’)

I cannot figure out the way to adapt my dart model to my json. I constantly get the error in BreedInfo class, field height: _TypeError (type ‘_InternalLinkedHashMap<String, dynamic>’ is not a subtype of type ‘String?’) I do not know why it does not accept a response if dynamic is supposed to identify the data type … Read more
