So here's the situation. I've got an 85 Million row table with 18 columns. Three of these columns have values in Metric Prefix / SI notation (See Metric Prefix on Wikipedia). This means I have num...

How do I get the probability of a string being similar to another string in Python? I want to get a decimal value like 0.9 (meaning 90%) etc. Preferably with standard Python and library. e.g. si...

Could anybody tell me how could I compute Equal Error Rate(EER) from ROC Curve in python? In scikit-learn there is method to compute roc curve and auc but could not find the method to compute EER. ...

I have a model in Keras which I'm optimizing the mean squared error. However, if I use the same code as in losses.py from Keras in the metric, I get a different result. Why is this? As a metric: ...

So far, I have read some highly cited metric learning papers. The general idea of such papers is to learn a mapping such that mapped data points with same label lie close to each other and far from...

I followed the instructions on http://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/as-scale-based-on-demand.html in order to have a CPUUtilization based auto scale group. i noticed that th...

I have the following problem: I have an autoencoder in Keras, and train it for a few epochs. The training overview shows a validation MAE of 0.0422 and an MSE of 0.0024. However, if I then call n...

I am doing a webcrawler and using threads to download pages. The first limiting factor to the performance of my program is the bandwidth, I can never download more pages that it can get. Th...

In Kibana, I have an index that looks like as follows type (String) value (String) timestamp (Date) I would like to have a visualization that shows the most recent value field where the type is...

I have a large collection of objects and I need to figure out the similarities between them. To be exact: given two objects I can compute their dissimilarity as a number, a metric - higher values ...

I prepared several models for binary classification of documents in the fraud field. I calculated the log loss for all models. I thought it was essentially measuring the confidence of the predictio...

Is there some robust metric of image sharpness or bluriness? I have various set of images with different parameters of saturation and captured from different optical systems, and i heed to show use...

I just applied the log loss in sklearn for logistic regression: http://scikit-learn.org/stable/modules/generated/sklearn.metrics.log_loss.html My code looks something like this: def perform_cv(cl...

I have two cv::Scalar objects and I want to calculate the color difference. I came up with this code: cv::Scalar a(255, 128, 255); // color 1 cv::Scalar b(100, 100, 100); // color 2 cv::Scalar d...
