data/input/titanic/raw/ : the raw files
data/input/titanic/raw2/ : the raw files split manually
data/input/titanic/train/ : features.zip , target.zip, cols_group.json names are FIXED
features.zip or features.parquet : csv file of the inputs
target.zip or target.parquet : csv file of the label to predict.
data/input/titanic/test/ :
features.zip or parquet format , used for predictions
File names Are FIXED, please create sub-folder

(1) Initial Manual Column Mapping : 'cols_input_type'
From Raw data --> "colid","colnum","colcat","coldate","coltext","coly","colcross"
|-"colid" --> index or id of each row (e.g. ["PassengerId"])
|-"coly" --> target column or y column (e.g. ["Survived"])
|-"colnum" --> columns with float or interger numbers (e.g. ["Pclass", "Age", "SibSp", "Parch", "Fare"])
|-"colcat" --> columns with string labels (e.g. ["Sex", "Embarked"])
|-"coldate" --> columns with date format data
|-"coltext" --> columns with text data (e.g. ["Ticket", "Name"])
|-"colcross" --> columns to be checked for feature crosses
(e.g. ["Name", "Sex", "Ticket", "Embarked", "Pclass", "Age", "SibSp", "Parch", "Fare"])
(2) Some Columns feature family for model training : "cols_model_group"
"cols_model_group" --> column family used for Model Training
"colnum", "colnum_bin", "colnum_onehot", "colnum_binmap", #### Colnum columns
"colcat", "colcat_bin", "colcat_onehot", "colcat_bin_map", #### colcat columns
'colcross_single_onehot_select', "colcross_pair_onehot", 'colcross_pair', #### colcross columns
'coldate',
'coltext',
Preprocessing as follow in source/run_preprocess.py
Columns family input ---> Preprocess ---> Feature columns family output
"colnum" --> "colnum_bin" --> "colnum_onehot" --------------->
|--------------------------> "colnum_onehot" --------------->
"colcat" --> "colcat_bin" --> "colcat_onehot" --------------->
|--------------------------> "colcat_onehot" --------------->
"coltext" -(bag of words)-> "dftext_tfidf" --> "dftext_svd" -->
|-------------------------->
