How can I combine unsupervised learning with supervised learning?
I am currently using an isolation forest (from sklearn library) to detect anomalies in a data frame (basically it's a dynamic data frame more of a kind of time series I am. But I have certain criteria ...

What is the best clustering method to detect anomalies for data with mostly categorical data?
I have a dataset with about 85 columns. Out of the 85 columns, 70+ are categorical. My goal is to identify the outliers in this dataset through clustering methods as I do not have a target column.
...

How can auto-encoders compute the reconstruction error for the new data?
Autoencoders are used for unsupervised anomaly detection by first learning the features of the data set with mainly "normal" data points. Then new data can be considered anomalous if the new ...

Which unsupervised learning algorithm can be used for peaks detection?
So, I have a dataset that has around 1388 unique products and I have to do unsupervised learning on them in order to find anomalies (high/low peaks).
The data below just represents one product. The <...

Which unsupervised learning technique can be used for anomaly detection in a time series?
I've started working on anomaly detection in Python. My dataset is a time series one. The data is being collected by some sensors which record and collect data on semiconductor-making machines.
My ...

Are there any advantages of using rules-based approaches versus models for detecting spam?
Suppose that we have unlabeled data. That is, all we have are a collection of emails and want to determine whether any of them is spam or not. Let's say we have $1,000$ rules to determine whether a ...
