Hello guys i am a biggner at computer vision and classification, i am trying to train a model using cnn method with tensorflow and keras, but i keep getting the error bellow this code , could anyone help me or give me at least a peace of advice?
...ANSWER
Answered 2022-Mar-16 at 09:55You just have to make sure your labels are zero-based starting from 0 to 2, since your output layer has 3 nodes and a softmax activation function and you are using sparse_categorical_crossentropy. Here is a working example:
QUESTION
I have an ODE which I would like to solve using compiled C code called from R's deSolve package. The ODE in question is I an exponential decay model (y'=-d* exp(g* time)*y): But running the compiled code from within R gives different results to R's native deSolve. It's as is there they are flipped 180º. What's going on?
C code implementation ...ANSWER
Answered 2022-Mar-13 at 11:01Compiled code does not give different results to deSolve models implemented in R, except potential rounding errors within the limits of atoland rtol.
The reasons of the differences in the original post where two errors in the code. One can correct it as follows:
- Declare
static doubleasparms[3];instead ofparms[4] - Time
tin derivs is a pointer, i.e.*t
so that the code reads as:

I've looked for an answer to this one, but I can't seem to find anything, so I'm asking here:
Do reference parameters decay into pointers where it is logically necessary?
Let me explain what I mean:
If I declare a function with a reference to an int as a parameter:
...ANSWER
Answered 2022-Mar-04 at 21:18The compiler can decide to implement references as pointers, or inlining or any other method it chooses to use. In terms of performance, it's irrelevant. The compiler can and will do whatever it wants to when it comes to optimization. The compiler can implement your reference as a pass-by-value if it wants to (and if it's valid to do so in the specific situation).
Caching the result won't help because the compiler will do that anyways.
If you want to explicitly tell the compiler that the value might change (because of another thread that has access to the same pointer), you need to use the keyword volatile (or std::atomic if you're not already using a std::mutex).
Edit: The keyword "volatile" is never required for multithreading. std::mutex is enough.
If you don't use the keyword volatile, the compiler will almost certainly cache the result for you (if appropriate).
There are, however, at least 2 actual differences in the rules between pointers and references.
- Taking the address (pointer) of a temporary value (rvalue) is undefined behavior in C++.
- References are immutable, sometimes need to be wrapped in std::ref.
Here I'll provide examples for both differences.
This code using references is valid:
QUESTION
ANSWER
Answered 2022-Mar-01 at 08:54The code won't do what the author presumably wanted it to do, but there's no UB. While comparing pointers to unrelated objects with < has unspecified results, checking equality is fine, and the comparison will produce false.

QUESTION
I am currently having issue with the implementation of the Metropolis-Hastings algorithm.
I am trying to use the algorithm to calculate integrals of the form
In using this algorithm, we can obtain a long chain of configurations ( in this case, each configuration is just a single numbers) such that in the tail-end of the chain the probability of having a particular configuration follows (or rather tends to) a gaussian distribution.
My code seems to be messing up with obtaining the said gaussian distributions. There is a strange dependence on the transition probablity (the probablity of picking a new candidate configuration depending on the previous configuration in the chain). However, if this transition probability is symmetric, there should be no dependence on this function at all (it only affects speed at which phase space [space of potential configurations] is explored and how quickly the chain converges to the desired distribution)!
In my case I am using a normal distribution transition function (which satisfies the need to be symmetric), with width d. For each d I use I do indeed get a gaussian distribution however the standard deviation, sigma, depends on my choice of d. The resulting gaussian should have a sigma of roughly 0.701 but I find that the value I actually get depends on the parameter d, when it shouldn't.
I am not sure where the error in this code is, any help would be greatly appreciated!
...ANSWER
Answered 2022-Feb-02 at 20:28You need to save x even when it doesn't change. Otherwise the center values are under-counted, and more so as d increases, which increases the variance.

QUESTION
C++20 introduced std::span, which is a view-like object that can take in a continuous sequence, such as a C-style array, std::array, and std::vector. A common problem with a C-style array is it will decay to a pointer when passing to a function. Such a problem can be solved by using std::span:
ANSWER
Answered 2021-Nov-27 at 02:27The question is not why this fails for int[], but why it works for all the other types! Unfortunately, you have fallen prey to ADL which is actually calling std::size instead of the size function you have written. This is because all overloads of your function fail, and so it looks in the namespace of the first argument for a matching function, where it finds std::size. Rerun your program with the function renamed to something else:

This question is the same with How can I check a confusion_matrix after fine-tuning with custom datasets?, on Data Science Stack Exchange.
BackgroundI would like to check a confusion_matrix, including precision, recall, and f1-score like below after fine-tuning with custom datasets.
Fine tuning process and the task are Sequence Classification with IMDb Reviews on the Fine-tuning with custom datasets tutorial on Hugging face.

Answered 2021-Nov-24 at 13:26What you could do in this situation is to iterate on the validation set(or on the test set for that matter) and manually create a list of y_true and y_pred.
