ProFAB is a benchmarking platform for GO term and EC number prediction. It provides several datasets, featurization and scaling methods, machine learning algorithms and evaluation metrics.
As seen from the figure, in ProFAB, four main modules import_dataset, model_preprocess, model_learn, model_evaluate are employed.
- import_dataset: lets to construct individual datasets for each GO term and EC number.
- model_preprocess: provides three submodules for data preprocessing i.e., splitting, featurization and scaling.
- model_learn: consists of several machine learning algorithms for binary classification. In this module, hyperparameter optimization is automatically done to determine the best performing models.
- model_evaluate: provides several evaluation metrics to assess the performance of the trained models.
ProFAB availabilty:

ProFAB has many workloads, therefore, reading the introductions is highly recommended. Detailed explanations can be found in each module: import_dataset, model_preprocess, model_learn, model_evaluate.
To run ProFAB on terminal, easy_profab can be used. Its parameters are given in Table.1:
Table.1: Parameters to run ProFAB on terminal:
| Parameters (type) | options | default | Definition |
|---|---|---|---|
| file_name (str) | - | - | File includes dataset names such as GO_0000018, GO_1905523. If isUser = True or isFasta = True, then directory to dataset folder must be defined in input file. Each must be defined in new line |
| score_path (str) | - | 'score_path.csv' | A destination where scores are saved. It must be .csv file |
| model_path (str) | - | None | A destination where model parameters of given dataset are saved. |
| set_type (str) | 'random' 'similarity' 'temporal' |
'random' | split type of data, random: random splitting, target: similarity based splitting, temporal: splitting according to annotation time. If isUser or isFasta is True, random splitting will be applied to data even though set_type is not 'random' splitting. 'similarity' and 'temporal' splitting options are valid for only ProFAB datasets. |
| protein_feature (str) | 'paac' 'aac' 'gaac' 'ctriad' 'ctdt' 'soc_number' 'kpssm' |
'paac' | numerical features of protein sequences. If isFasta = True, options can be found in Table.2, Table.3 and Table.4 |
| ratio (float, list) | - | 0.2 | used to split data into train, test, validation sets as given values. If ratio = a (float), then test will be a% of total data size. If ratio = [a,b] where a and b are in (0,1), train, test and validation sets are formed according to them. For example, If a = 0.2 and b = 0.1, train fraction is 0.7, test fraction is 0.2 and validation fraction is 0.1 of all dataset size. If set_type = 'temporal', then ratio = None is set automatically by ProFAB. |
| pre_determined (bool) | - | False | if False, data is given according to ratio type, If True, already splitted data will provided |
| scale_type (str) | 'normalizer' 'standard' 'max_abs' 'min_max' 'robust' |
'standard' | determines the method to scale the data |
| ml_type (str) | 'logistic_reg' 'ridge_class' 'KNN' 'SVM' 'random_forest' 'MLP' 'naive_bayes' decision_tree' 'gradient_boosting' 'xgboost' 'lightgbm' 'CNN' 'RNN' 'CNN' |
'logistic_reg' | type of machine learning algorithm |
| isFasta (bool) | - | False | If True, a data provided by user is Fasta file else numerical data should be introduced. While isUser = True, this parameter cannot be True at the same time. Format of fasta files must be .fasta and names of files should describe label. The path described in input file must include these files: "positive_data.fasta" and "negative_data.fasta" |
| output_fasta (str) | - | '' | Name of folder where output will be saved |
| max_len (int) | - | -1 | Max sequence lenght to embed (arg for NLP methods) |
| place_protein_id (int) | - | 1 | It indicates the place of protein id in fasta header. e.g. fasta header: >sp |
| isUser (bool) | - | False | If True, user data path must be defined in input file. While isFasta = True, this parameter cannot be True at the same time. If label = False, names of files should describe label. As an example, The path described in input file must include these files: "positive_data.txt" and "negative_data.txt". If label = True, it doesn't matter |
| delimiter (str) | '\t' (tab) ',' (comma) ' ' (space) |
'\t' | a character to separate columns in file |
| name (bool) | - | False | If True, then first colmun is considered as name of inputs else the first column is a feature column |
| label (bool) | - | False | If True, then last colmun is considered as label of inputs else the last column is a feature column |
It can be run on terminal with a single line:
where isFasta = False and isUser = False, use support vector machine as training algorithms and save perfomance of model to my_score_path.csv:
python easy_profab.py --file_name sample_inputs.txt --score_path my_score_path.csv --ml_type SVM
where isUser = True, use k-nearest neighbor as training algorithm and test fraction is 0.3 and feature matrices include names of instances:
python easy_profab.py --file_name sample_inputs_userTrue.txt --isUser True --ml_type KNN --ratio 0.3 --name True
where isFasta = True, use random forest as training algorithm , protein descriptor is CTRIAD, test fraction is 0.1 & validation fraction is 0.2:
python easy_profab.py --file_name sample_inputs_fastaTrue.txt --isFasta True --ml_type random_forest --protein_feature CTriad --ratio 0.1,0.2
ProFAB can be run in pythonic way. How to apply its functions are shown in two different use cases. use_case_1 is based on utilizing ProFAB datasets whereas use_case_2 is based on integrating user itself datasets. Detailed explanations can be found in links.
