Quick-Show

Quick-Show helps you draw plots quickly and easily.
It is an abstraction using popular libraries such as Scikit-Learn and MatPlotLib, thus it is very light and convenient.

Note: Quick-Show is sub-modules of other packages to manage quickshow more lightly and use more widly. This is a project under development. With the end of the project, I plan to provide documents in major version 1 and sphinx. It is NOT recommended to use prior to major version 1.

Installation

$ pip install quickshow

Tutorial

1. Main-tutorials: https://github.com/DSDanielPark/quick-show/blob/main/tutorial/tutorial.ipynb
2. Sub-tutorial-folder: Tutorials for each function can be found in this folder. The tutorial is synchronized with the Python file name provided by QuickShow.

Features

1 Related to dimensionality reduction

2D or 3D t-SNE and PCA plots using specific columns of a refined dataframe. Create a scatter plot very quickly and easily by inputting a clean dataframe and column names that do not have missing data.

1. vis_tsne2d: Simple visuallization of 2-dimensional t-distributed stochastic neighbor embedding
   
2. vis_tsne3d: Simple visuallization of 3-dimensional t-distributed stochastic neighbor embedding
   
3. vis_pca: Simple visuallization of Principal Component Analysis (PCA)

2 Related to classification model evaluation.

Later these functions are encapsulated into classes.

3. vis_cm: Visuallization heatmap of confusion_matrix and return classification report dataframe.
   
4. get_total_cr_df: When the confusion matrix dataframe created by the vis_cm function is saved as csv, the directory of the folder where these csv files exist is received as input and the confusion matrices of all csv files are merged into a single data frame.
   
5. vis_multi_plot: It takes the return dataframe of get_total_cr_df as input and draws a nice plot. However, if you want to use this function, please note that the suffix of the multiple csv files input to get_total_cr_df must be exp and an integer, such as exp3, and the integers must be contiguous.

3 Related to clustering.

6. vis_cluster_plot: Produces a plot to see how spread out the actual label values ​​are within the clusters.
   

4 Utils

7. find_all_files: If you enter the top folder path as an auxiliary function, it returns a list of files including keywords while recursively searching subfolders. This is implemented with the glob package.
   
8. rcparam: It simply shows some rcparams method in matploblib. Check by calling qs.rcparam?

Examples

Feature 1

See example dataframe...

import pandas as pd
df = pd.DataFrame([3,2,3,2,3,3,1,1])
df['val'] = [np.array([np.random.randint(0,10000),np.random.randint(0,10000),np.random.randint(0,10000)]) for x in df[0]]
df.columns = ['labels', 'values']
print(df)

	labels	values
0	3	[8231 3320 6894]
1	2	[3485 7 7374]
...	...	...
6	1	[5218 9846 2488]
7	1	[6661 5105 136]

from quickshow import vis_tsne2d, vis_tsne3d, vis_pca

return_df = vis_tsne2d(df, 'values', 'labels', True, './save/fig1.png')
return_df = vis_tsne3d(df, 'values', 'labels', True, './save/fig2.png')
return_df = vis_pca(df, 'values', 'labels', 2, True, './save/fig3.png')
return_df = vis_pca(df, 'values', 'labels', 3, True, './save/fig4.png')

• All function returns the dataframe which used to plot. Thus, use the returned dataframe object to customize your plot. Or use matplotlib's rcparam methods.
• If the label column does not exist, simply enter None as an argument.
• For more details, please check doc string.

Feature 2

See example dataframe...

import pandas as pd
label_list, num_rows = ['cat', 'dog', 'horse', 'dorphin'], 300
df = pd.DataFrame([label_list[np.random.randint(4)] for _ in range(num_rows)], columns=['real'])
df['predicted'] = [label_list[np.random.randint(4)] for _ in range(num_rows)]  
print(df)

	real	predicted
0	cat	cat
1	horse	cat
...	...	...
7	horse	dog
299	dorphin	horse

from quickshow import vis_cm

df_cr, cm = vis_cm(df, 'real', 'predicted', 'vis_cm.csv', 'vis_cm.png')

print(df_cr)

	cat	dog	dorphin	horse	accuracy	macro avg	weighted avg
precision	0.304878	0.344828	0.285714	0.276316	0.3	0.302934	0.304337
recall	0.328947	0.246914	0.328767	0.3	0.3	0.301157	0.3
f1-score	0.316456	0.28777	0.305732	0.287671	0.3	0.299407	0.299385
support	76	81	73	70	0.3	300	300

confusion matirx will be shown as below.

• This function return pandas.DataFrame obejct of classification report and confusion metix as shown below.
