If we have more than 2 classes in categorical variables, for eg, 2 classes in one variable and 3 classes in another variable, then also chi square can be used ? Please help sir.

Thanks, I think For a situation with limited data, RandomizedSearchCV is recommended over GridSearchCV. but you say GridSearchCV can you clarify?
@UnfoldDataScienceКүн бұрын
There is debate on this but yes RandomizedSeachCV is also a good option for small data. I prefer GridSearchCV to ensure that every possible combination is evaluated, particularly if the parameter space is small or manageable.

what is normal distribution?
@UnfoldDataScienceКүн бұрын
A normal distribution, also known as the Gaussian distribution, is a continuous probability distribution characterized by its bell-shaped curve. It is fundamental in statistics and is often used to represent real-valued random variables with a distribution that is symmetric around the mean.

SimpleDirectoryReader(input_files=[xyz.pdf]).load_data() throws the error: cannot import name 'DocxReader' from 'llama_index.readers.file' and `llama-index-readers-file` package not found, despite all packages being present. WHat can I do to fix it
@UnfoldDataScienceКүн бұрын
This suggests an issue with the import statement or module availability, possibly due to a change in the library's structure or your environment setup.

How can i read the graph of silhouette score? Most important thing you didn't tell
@UnfoldDataScienceКүн бұрын
Positive Scores (close to 1): Samples are well-clustered, and there is good separation between clusters. Scores around 0: Samples are on or near the boundary between clusters, indicating potential overlap. Negative Scores: Samples are likely in the wrong cluster.

The example is not reality. Real data in not like minimizing f(x,y) = x^2+y^2 or even the Rosenbrock formula. In reality the terrain is more like the Grand Canyon where the correct path is very narrow and any direction will often hit a canyon wall. I also object to instructor that don't have working examples. Writing on a whiteboard doesn't hack it anymore.
