# Example Applications

The initial primary target market for Parallel AI’s parallel processing solution will be AI developers where the need for optimizing computational speeds is currently most urgent. Once it has been proven out in the AI sector however, it can also be applied to improving processing efficiency for the gaming, media production and cryptocurrency mining sectors, amongst others.

Within the AI sector, some of the initial key applications for Parallel AI’s parallel processing solution will include training machine learning models and running inference on trained models:

* **Training Machine Learning Models:** The training process, especially in deep learning models, involves operations like gradient calculations and weight updates that can be executed across different subsets of data simultaneously. For training large-scale models, such as deep neural networks, the gradient descent step, where parameters are adjusted to minimize error, can be parallelized. Data batches can be processed simultaneously across multiple GPUs, allowing for the gradients to be computed in parallel. The partial gradients are then aggregated to update the model parameters. This significantly speeds up the training process, especially for models with a large number of parameters and large datasets.
* **Inference:** Running inference on trained models can be distributed across multiple processing units to handle multiple requests or large input data sets efficiently. For models deployed in production, inference requests can arrive in large volumes and need to be processed quickly. By distributing these requests across a cluster of servers or GPU-accelerated devices, each device can handle a subset of the inference workload simultaneously. This not only improves response times but also scales the system's ability to handle peak loads more efficiently.



Some of the key sub-tasks where Parallel AI can achieve significant improvements to computation time and cost-efficiency include:

**Distributed Deep Learning:** Utilizing distributed computing to train large deep learning models over massive datasets, which can significantly speed up the training process by distributing computations across many GPUs or TPUs.

**Hyperparameter Optimization:** Running multiple training sessions with different hyperparameters in parallel to quickly find the most effective model configurations.

**Cross-Validation:** Implementing parallel processing to perform k-fold cross-validation, where multiple folds are processed simultaneously to validate the model's performance more efficiently.
