Why do higher learning rates in logistic regression produce NaN ...


Why do higher learning rates in logistic regression produce NaN ...

Higher learning rates lead to NaN values being calculated for the cost, yet it does not break/decrease the performance of the classifier itself.

Nan when trying different learning rates - DeepLearning.AI

The short answer is that with a higher learning rate you are forcing the model's gradient, and by implication the weights and the cost, into “ ...

Does high learning rate produces NaN? - PyTorch Forums

In your case your large updates are directly a result of having a large learning rate forcing a large update which causes your NaNs. Though if ...

Dealing with NaN (missing) values for Logistic Regression

Use caution when removing features with missing values. Sometimes the fact that a feature has missing values is valuable data in and of ...

Why do l get NaN values when l train my neural network ... - Quora

This simple 1D toy model exhibits same NaN behavior if we knock off the sigmoid layer, and just increase the number of nodes in single layer to ...

Cost function in logistic regression gives NaN as a result - Intellipaat

This is because when you apply the sigmoid / logit function to your hypothesis, the output probabilities are almost all approximately 0s or all ...

Cost function turning into nan after a certain number of iterations

Well, if you get NaN values in your cost function, it means that the input is outside of the function domain. E.g. the logarithm of 0.

Common Causes of NANs During Training | The Truth of Sisyphus

Reason: you have an input with nan in it!What you should expect: once the learning process "hits" this faulty input - output becomes nan.

DLS Course 1 Week 2 warning when running the logistic regression ...

That error most likely means that you have “saturated” sigmoid for some training samples, meaning that the output of sigmoid rounds to exactly 0 or 1.

Can a Logistic Regression Model handle nulls? : r/MLQuestions

Does Logistic Regression require no null values? If so, what is the efficacy of populating missing values with values based on the probability of obtaining one ...

How to Evaluate the Logistic Loss and not NaN trying

A naive implementation of the logistic regression loss can results in numerical indeterminacy even for moderate values. This post takes a closer look into the ...
