-- [x] **v1**: - - [x] **`ParamsBase`**: Design a basic structure for storing model parameters. - - [x] **Traits**: Create a set of traits for defining the basics of a neural network model. - - `Forward` and `Backward`: traits defining forward and backward propagation - - `Model`: A trait for defining a neural network model. - - `Predict`: A trait extending the basic [`Forward`](cnc::Forward) pass. - - `Train`: A trait for training a neural network model. -- [x] **v2**: - - [x] **`DeepModelParams`**: Extend the `ParamsBase` structure to support deep neural networks with multiple layers. - - [x] **Models**: Implement standard model configurations and parameters. - - `StandardModelConfig`: A standard configuration for neural network models. - - `ModelFeatures`: A structure to define the features of a model (e.g., number of layers, neurons per layer). - - [x] **Activation Functions**: Implement and refine various activation functions (`ReLU`, `Sigmoid`, `Tanh`, etc.) - - [x] **Loss Functions**: Implement common loss functions such as `MeanSquaredError` and `CrossEntropy` -- [ ] **v3**: - - [ ] **Optimizers**: Implement optimization algorithms like `SGD` and `Adam`. - - [ ] **Scheduler**: Learning rate schedulers to adjust the learning rate during training. - - [ ] **Layers**: Refine a more functional layer-based architecture. - - [ ] **Utilities**: Additional utilities for data preprocessing, model evaluation, and visualization +- Implement additional optimization algorithms (e.g., Adam, RMSProp). +- Add support for convolutional and recurrent neural networks. +- Expand the set of built-in layers and activation functions. +- Improve documentation and provide more examples and tutorials. +- Implement support for
