The Capital One Services LLC invention works as follows

A system for determining data requirements to generate machine-learning models. The system can include one or multiple processors, and one or several storage devices that store instructions. The instructions can configure the processors to perform various operations, including: receiving a dataset and generating data categories. Generating a plurality primary models using the data of the respective data category as training data. Generating a sequence secondary models, by training the corresponding primary model with progressively less data.

Background for System and Method for Efficient Generation of Machine-Learning Models

In machine learning and artificial-intelligence modeling, training datasets are used to configure predictive and classification models. Modeling algorithms adjust parameters and customize operations to perform prediction or classification tasks using the training datasets. Hyper-parameters govern the training process. These parameters set the basic elements of the models and are not directly linked to the training data. Hyper-parameters can include, for example, the number of trees selected to govern the training of random forests. Hyper-parameters can also include the number hidden layers which govern a neural networks training.

Training machine-learning models requires both hyper-parameters and parameters to be adjusted. In order to generate a predictive model, for example, hyper-parameters are selected, the parameters of the model are adjusted based on training data, the prediction is compared with validation data, the accuracy is evaluated, and the parameters may be adjusted until the target accuracy has been achieved. To achieve a successful machine-learning model, a model’s parameters are not enough. The tuning of hyper-parameters for machine-learning is an essential part of the training process. To tune hyperparameters the entire training job is repeated with different hyperparameters.

The tasks required to create machine-learning models are often time-consuming and costly. The first is that training models can be computationally expensive, as it requires large datasets with a multitude of data points. In order to adjust values in a model while processing petabytes or terabytes worth of data, expensive parallel frameworks and supercomputers are usually required. The second is that tuning hyper-parameters to a dataset can also require significant computing resources, as iterations are required for tuning. This could lead to a large increase in computer costs. Even when tuning iterations are spread across multiple processing units tuning processes still take a lot of time and consume a lot of resources. They also create complex challenges in terms resource allocation and coordination.

After training a model users often realize that computer resources have been wasted because the model failed to achieve the target accuracy, or it turned out to be “overfitted.” Overfitting occurs when a model has too many parameters in relation to the number observations and a low prediction accuracy. Overfitted models are the result of training with a large sample size or too many iterations. In such cases, parameters are too closely correlated to the training data, and the model is unable to work with independent data. Overfitted models begin to memorize the data without evaluating its general trend. Overfitted models waste a lot of computational resources. Overfitted models not only use more resources, as they require processing a large dataset for training and additional tuning iterations. They also have lower accuracy, which forces users to restart their training process using alternative configurations.

The disclosed system and method for efficient generation of machine-learning and artificial-intelligence models address one or more of the problems set forth above and/or other problems in the prior art.

One aspect” of the disclosure is a system that determines data requirements for machine-learning models. The system can include one or multiple processors, and one or several storage devices that store instructions. The instructions can configure the processors when executed to perform various operations, including: receiving a sample dataset from a database; generating data categories from the dataset; generating primary models from each data category using the corresponding data as training data. Primary models may include different model types. For each primary model, generating secondary models from training each primary model with less and less training data.

The operations may include receiving, from a database, a sample dataset including a plurality of samples; generating corresponding data categories based on the sample dataset, the data categories being associated with category data profiles; for each of the different data categories, generating varying primary models using the corresponding one of the training information, the primary models including different model types; for each one the primary models, determining progressively less training to train the corresponding one the secondary model. The operations can include receiving a sample dataset from a database including a variety of samples, generating data categories from the sample dataset and associated data profiles, and then generating primary models for each data category using the data as training data. Each primary model may have different model types.

The present disclosure also includes a computer-implemented technique for determining the data requirements required to create machine-learning models. The method can include receiving, from an online database, a dataset of samples, and creating a plurality data categories. These data categories are associated with data profiles. For each data category, it is possible to generate a variety of primary models that have different types.

The disclosure is directed at systems and methods that are efficient in generating machine-learning algorithms for prediction or classification. The disclosed methods and systems may improve model generation by estimating the minimum data requirements before training the model. In some embodiments the system can estimate the minimum requirements by creating sample models using different datasets with different data profiles. The system can determine and store correlations among data profiles, target models types, tuned hyperparameters and the minimum number of samples required (for training or validating) to achieve a desired accuracy. When a user attempts to create a model from a new dataset the system can identify a closely-related data profile and estimate the minimum requirements for the model based upon a sample model that is associated with the data profile.

Estimating the minimum data requirements can reduce the computing resources needed to generate the new model. When the new dataset exceeds the minimum number of samples required, a new model can be created using a small portion of the user dataset. By limiting the dataset, you can avoid overprocessing training data and prevent potential overfitting. Moreover, by reducing the number of samples, the complexity of the models can be reduced (e.g. reduce the number parameters), which could reduce resource consumption at hyper-parameter optimization or other stages. The system can also save resources by not generating models which will not reach a target accuracy due to insufficient training data. The system can inform a user if the model will not reach the target accuracy using the training data available, saving resources.

In some embodiments, the system can also recommend or suggest model types on the basis of the dataset provided by the user. The system can, for example, generate several types of sample model (including regressions and instance-based models, clustering models, and deep learning models), and estimate the minimum data requirements of each type. The system can then recommend a type of model that will achieve the desired accuracy based on the user’s dataset. Using the sample models, the system can also make it easier to determine hyper-parameters when creating new models. Sample models can be simplified and optimized because they are trained using smaller datasets. In some embodiments, a system may be able to compare datasets using their data profiles in order to estimate similarity between training datasets. The system can, for example, use a statistical analysis to identify a data profile most closely related with the user data used to create a new model. The system can then tune parameters and hyperparameters based on the configuration of a sample model that was trained using a small sample dataset, but has a similar profile. It may also use the same hyperparameters or similar ones for the new model. The system could then reduce the cost of tuning hyper-parameters, and improve the efficiency of the predictive model generation.

In some embodiments, a user may find it easy to operate the system via a graphic user interface on client devices. The graphical interface may include controls, recommendations and/or options to automatically train models with parameters and hyperparameters likely to produce the most efficient models.

The disclosed systems and method address the technical problem of reducing computing resources during the generation and estimation of data requirements for new model. The disclosed systems and method also improve computer functionality by avoiding costly guess-and check optimizations which result in machine-learning models that are over- or under-tuned. The disclosed systems and methods also improve resource allocation in parallelized processes of predictive model generation. By comparing data profiles, disclosed systems and method may also avoid low-performing systems due to unexpected variances in the dataset. This is done by identifying similar sample models which reduce the complexity of hyperparameter tuning. These features lead to systems and methods which improve the efficiency of computerized systems in generating machine-learning algorithms.
