kandi X-RAY | 4917 Summary
This is an emulator for the 4917 CPU created for CS1 at The University of New South Wales. A video explaining the CPU is available at this link. I have also found documentation of the instructions at this link. A counting program is available in the examples directory. If you are looking for something to contribute to, the emulator is fully functional. We are currently lacking on examples. If you would like to help with examples, please make some and send me a pull request.

QUESTION
I have 3 columns namely Models(should be taken as index), Accuracy without normalization, Accuracy with normalization (zscore, minmax, maxabs, robust) and these are required to be created as:

QUESTION
I am trying to return a specific table from this webpage.
I have tried to scrape it using beautifulsoup but that got way too complicated so I an trying to use pd.read_html instead. The table I'm after is the one with "XYZ Substantial Shareholders" (note that this is just one particular page, I would be using this code to return tables from other stocks as well).
This is the code that I'm currently using to search for the tables - my initial idea was to find the word 'Holding' in the header of the title I'm after, but it has also picked up another table which I didn't want because the word 'Holdings' appeared in an earlier table.

QUESTION
I am handling error by using scopes in my Logic App. In case of an error I get the result of the scope which has thrown the error.
The problem is that the result contains all results of all steps contained in the relevant scope. This is looking like this (shortened version):
...ANSWER
Answered 2021-Nov-01 at 08:14You will need to loop through each of the items in the "body". First parse each item and check if the "status" is = "Failed". If yes, then append it to a new array variable and return that result. This is shown in the attached picture.
The JSON code is below.
QUESTION
I was attempting to fill an empty vector of values using a for
loop and then reference specific entries from these vectors to fill a data frame. After doing a little researching it appears my vector got converted to a list
. But I'm not sure how that occurred. The code is pretty simple, unless there is another underlying nuance that I'm missing. Here is the code I used:
ANSWER
Answered 2021-Oct-03 at 16:26The fifth column of your input data, the Estimated_mean_response
is a 1-d matrix. So your output is a vector of matrices. Not sure how that happened, but I would just convert that column to a regular numeric column and everything should work as you expect from there.

I am using Xcode 12.5 on macOS Big Sur 11.3
After updating to the latest versions of both React Native, Xcode, and macOS I can't run my app in the iOS simulator. So far I have gone with yarn start --reset-cache
, as well as pod install
in the ios folder before running the app.
The error message I get from running react-native run-ios:

QUESTION
I have created a minimum spanning tree in which communities have been found using the Louvain method. I would now like to display the tree clearly, i.e., it would be great to have an overlap-free representation.
On the left is my current plot and on the right is a very nice example from Wang et al. (2017, JEIC), which is much clearer and mostly non-overlapping.
I wonder how it can be achieved to represent this tree more clearly, in particular it must be noted that this representation is only an MWE and the actual representation has much more observations.
MWE:
...ANSWER
Answered 2021-Apr-02 at 13:07First of all, your vertices are much larger than in the "nice" graph. I will use a smaller node size. But the main point is that you should specify the layout. A couple of options worth trying are layout_as_tree
and layout_with_gem
. Here is what I got.
QUESTION
I have a time series data with (4917, 50, 136) as (batch, step, feature)
There are a total of 8 classes.
I'd like to run a tree decision before I train them with LSTM model to understand the similarities among the classes.
After I fit the tree for an 8-class dataset.
X_train.shape = (245850, 136)
y_train.shape = (245850,)
I tried to plot a tree but only texts coming out and Jupyter shows that the code is still running.
...ANSWER
Answered 2021-Jan-30 at 12:22Your plot output is correct. This is the decision tree model you obtained.
If you want to have a more "small" and "simple" decision tree to visualise a preliminary explanation you should tune some hyperparameters of the model.
Concretely, I recommend adjust your max_depth
to 5, or even less (with this hyperparameter, your tree won't be able to have a depth bigger than that value). As a result, you will obtain a simple model, but you would be able to obtain the basic information you are looking for:

does not know that your variables are non-negative. The solver goes into the negative zone (because from (1, 1) gradients tell to go towards the negative zone), gets NaNs there, and gets stuck. You should tell somehow where you are looking for a solution.fsolve
does not support bounds directly.least_squares
can do this.There are several solutions. (0, 0) is also fit. You probably have to somehow push away from it, because it seems not what you want to get from a solver.
You may try something like that.
