Use Gnuplot to enable the plotting of data from DataFrames with a new set of lambdas in Plot.h

Use the grid search to find a starting set of values for C and gamma. Then use those starting values as the input to a real optimizer.

Consider trying to use the simulated annealing functionality built-in to GSL.

It's also possible to launch a small pool of simulated annealing optimizers concurrently and then exit as soon as a desired level of accuracy is reached.

The program has a pretty decent design so far, but it's a little bit inconsistent and limited.

I would like the following changes:

• Get rid of the double limitation by using unions instead (don't need boost::variant because string data can be converted to/from char*. I also don't want to use templates because having vectors of generic templated things gets really messy.
• Redo the relationship between the built-in chainable functions and the various data classes. Any chainable should not be directly accessing data in a class instance, but instead calling an appropriate class method. This may require ditching the fancy automatic lambdas by using std::function and a naming convention for common operations like dl_filter, df_filter, and dfl_filter for DataLists, DataFrames, and DataFrameLists respectively

No need to reinvent the wheel for something like making plots - manually calling Gnuplot is inconvenient and the plots render a little strangely.

So, switch to use something that can be installed with vcpkg like https://github.com/lava/matplotlib-cpp or maybe https://github.com/sciplot/sciplot

The following plot of 1,1 2,2 3,3 4,4:

• Contains an extra point and
• Is low-resolution (possibly due to 4k monitor)

Interpreted environments like R and Python's Jupyter notebooks have the advantage of storing large datasets in memory and allowing for code to be modified and re-run without having to re-load the data.

Being compiled and not interpreted, analysis with C++ requires that data be re-loaded from the disk every time a change in the rest of the code occurs, impeding development.

With something like Boost's interprocess library it could be possible to avoid re-loading data from disk in C++.

This could be accomplished by running two scripts: one for data loading, and another for analysis. The data loading script can stay running in the background, and the analysis script can just access a pointer to the shared memory of the data loading script every time it is re compiled instead of re-loading from disk.

It would be really good to create methods for DataList that act in a way very similar to std::vector such as:

• at()
• push_back()
• begin()
• end()
• size()

Along with a larger selection of constructors - maybe even a curly brace initializer!

This would let users use DataLists as a direct stand-in for vectors plus all the ADSL functionality.

These methods can probably just be wrappers around the DataList.vals field's methods.

Writing an ARIMA model from scratch (plus an optimizer) seems to0 difficult - could just require that R is installed on the system and make a wrapper for R's auto.arima model

Create a utility function or a DataFrame class method to load a matrix of doubles from a CSV into a DataFrame.

• Have user specify whether or not there is a "header" list of column names.
• Auto-detect the number of columns in the dataset
• Have user specify delimiter

Don't worry about DataList (can always convert a 1-column file to a DataList with the getFirst lambda)

This project needs to be reorganized a little bit:

• Example cpp files will be in their own folder
• included archives and other files will be in their own folder
• ta-lib and ctsa will be in their own include_lib folder
• a bash script will install all dependencies (including vcpkg w/ unzip etc)
• one bash script will build standalone object files from the library
• another bash script will take a command-line argument to build a main cpp file and link to the library object files
• change the documentation to reflect these updates

The binaryClassifier function in Dlib.h works quite well when the LOOP_POL execution policy in DlibConst.h is set to std::execution::seq (single-thread).

The whole point of having the execution policy and the for_each loops is to effortlessly switch to parallel optimization of the classifier by changing LOOP_POL to std::execution::par. BUT, when I switch it over, this happens:
