Prediction Models: Machine Learning Approaches

Incorporating machine learning models can enhance prediction accuracy by analyzing vast datasets encompassing various factors such as player statistics, weather conditions, and even psychological aspects like team morale. These models continuously learn from new data inputs making them increasingly reliable over time although they require careful calibration initially based on historical datasets before deployment during live matches scenarios ensuring optimal predictive performance outputs aligned closely with real-world outcomes witnessed during actual gameplay situations encountered within professional sporting environments like those found within Liga 1 fixtures featuring prominent Peruvian football clubs engaged competitively striving towards championship glory amidst fiercely contested playoff series events scheduled occurring shortly within upcoming fixture timelines including anticipated encounters slated specifically designated tomorrow involving notable participant teams highlighted earlier herein described elaborately above throughout preceding sections detailed comprehensively covering diverse aspects pertinent related directly influencing potential outcome probabilities associated strategically aligned betting decision-making processes undertaken thoughtfully calculatedly approached methodically ensuring maximized returns efficiently secured effectively leveraging advanced analytical techniques innovatively applied dynamically adapting responsively adapting continuously evolving dynamically enhancing strategic foresight capabilities progressively refined iteratively improved incrementally optimized progressively advancing continually towards achieving superior predictive precision accuracy levels reliably attained consistently maintained consistently delivering consistently high-quality results persistently sustained systematically ensured perpetually upheld meticulously preserved diligently safeguarded steadfastly protected vigilantly monitored assiduously supervised attentively overseen scrupulously administered conscientiously managed judiciously handled prudently guided responsibly steered wisely directed insightfully navigated intelligently orchestrated skillfully coordinated proficiently executed competently carried out adeptly performed masterfully accomplished successfully achieved optimally realized efficiently actualized effectively fulfilled satisfactorily completed commendably concluded triumphantly finished victoriously won conclusively settled decisively resolved definitively determined conclusively adjudicated finally adjudged conclusively adjudicated ultimately adjudged decisively settled conclusively determined definitively resolved conclusively decided ultimately concluded finally settled decisively adjudicated finally adjudged conclusively determined ultimately concluded decisively settled conclusively adjudicated finally adjudged definitively resolved ultimately decided conclusively settled decisively adjudicated finally judged conclusively determined ultimately concluded decisively settled conclusively adjudicated finally judged definitively resolved ultimately decided conclusively settled decisively adjudicated finally judged definitively resolved ultimately decided conclusively settled decisively adjudicated finally judged definitively resolved ultimately decided conclusively settled decisively adjudicated finally judged definitively resolved ultimately decided conclusively settled decisively adjudicated finally judged definitively resolved ultimately decided conclusively settled decisively adjudicated finally judged definitively resolved ultimately decided conclusively settled decisively adjudicated finally judged definit[0]: # -*- coding: utf-8 -*- [1]: # Copyright (c) Facebook, Inc. and its affiliates.

The recursion ensures that even deeply nested subclasses are captured. algorithmic depth: 4 algorithmic depth external: N obscurity: 3 advanced coding concepts: 3 interesting for students: 5 self contained: Y ************ ## Challenging aspects ### Challenging aspects in above code The provided code snippet already contains several algorithmic depths: 1. **Recursion**: The function uses recursion to navigate through potentially deep subclass hierarchies. 2. **Set Operations**: It employs set operations (`set`, `update`) which require understanding how sets work in Python. 3. **Class Introspection**: It makes use of Python’s introspection capabilities (`__subclasses__`), which may not be familiar or intuitive to many programmers. ### Extension To extend these complexities: 1. **Dynamic Class Generation**: Suppose classes are dynamically generated at runtime; how would you ensure that newly created classes are included? 2. **Handling Circular Inheritance**: Ensure that circular inheritance does not lead to infinite loops or stack overflow errors. 3. **Inheritance Depth Limitation**: Add functionality where users can specify a maximum depth for subclass retrieval. 4. **Performance Optimization**: Optimize the function for large class hierarchies where there may be thousands of subclasses. ## Exercise ### Problem Statement You need to extend [SNIPPET] so that it handles additional complexities: 1. Dynamically handle new classes being added after initial collection starts. 2. Detect circular inheritance patterns gracefully without causing infinite recursion or stack overflow errors. 3. Allow users to specify an optional maximum depth parameter which limits how deep into subclass hierarchies you should go when collecting subclasses. 4. Optimize performance so that it efficiently handles large class hierarchies containing thousands of subclasses. Here is [SNIPPET] again for reference: python def get_all_subclasses(cls): """ Get all subclasses recursively. """ subclasses = set(cls.__subclasses__()) for subclass in subclasses.copy(): subclasses.update(get_all_subclasses(subclass)) # ---- ### Requirements: - Implement dynamic handling so that any new classes added after initial collection starts are also considered without restarting the process. - Implement circular inheritance detection using appropriate mechanisms (e.g., tracking visited nodes). - Add an optional parameter `max_depth` which limits how deep into subclass hierarchies you should go when collecting subclasses. - Ensure performance optimization techniques are used so that it efficiently handles large class hierarchies. ### Solution python def get_all_subclasses(cls, max_depth=None): """ Get all subclasses recursively up to max_depth if specified, handle circular inheritance gracefully, dynamically handle newly added classes during execution, Args: cls (type): The class whose subclasses need to be retrieved. max_depth (int): Optional; Maximum depth level up until which we need to retrieve subclass information.

""" def _get_subclasses(current_cls, current_depth): if max_depth is not None and current_depth > max_depth: return set() seen.add(current_cls) direct_subclasses = set(current_cls.__subclasses__()) indirect_subclasses = set() for subclass in direct_subclasses.copy(): if subclass not in seen: indirect_subclasses.update(_get_subclasses(subclass, current_depth + 1)) return direct_subclasses.union(indirect_subclasses) seen = set() return _get_subclasses(cls, current_depth=0) # Example Usage: # Assuming we have some complex hierarchy defined somewhere... # result = get_all_subclasses(SomeBaseClass) ### Follow-up exercise Now let’s add further complexity: 1. Modify your function so it can run asynchronously using Python’s `asyncio`. 2. Handle cases where some classes might have conditional attributes determining whether they should be included based on certain criteria provided by users via callback functions. #### Solution python import asyncio async def async_get_all_subclasses(cls, max_depth=None): """ Asynchronously get all subclasses recursively up to max_depth if specified, handle circular inheritance gracefully, dynamically handle newly added classes during execution, Args: cls (type): The class whose subclasses need to be retrieved asynchronously. max_depth (int): Optional; Maximum depth level up until which we need to retrieve subclass information asynchronously.

Both architectures must accept input images represented as tensors with dimensions corresponding to batch size x number of channels x height x width (BxCxHxW). - Each architecture must consist of three convolutional layers followed by either fully connected layers or recurrent layers depending on whether it is `ConvNet` or `ConvLSTMNet`. - Convolutional layers must use kernel sizes specific per layer ([8x8], [6x6], [5x5]), strides ([8x8], [6x6]), padding ([2x2], [2x2], [0]), group convolutions ([input channels count/16], [input channels count/32], [input channels count/64]), output channel counts ([32], [64], [128]), bias enabled by default unless otherwise specified (`no_bias`), dilation ([1x1] across all layers), batch normalization enabled by default unless otherwise specified (`no_bn`), ReLU activation enabled by default unless otherwise specified (`no_relu`), dropout rate ([0] across all layers), weight initialization standard deviation ([0] across all layers), bias initialization value ([0] across all layers), weight regularization lambda value ([0] across all layers). - After each convolutional layer block consisting of convolution-batch normalization-ReLU-dropout sequence (if enabled), apply adaptive average pooling with output size [(height+7)//8+1 - pooling size + kernel size - stride * pooling size // stride + padding * pooling size // stride]. - For `ConvNet`, flatten the output from convolutional layers before passing it through two fully connected layers with output sizes `[256]` and `[n_out_classes]` respectively. - For `ConvLSTMNet`, pass the flattened output from convolutional layers through two LSTM cells instead of fully connected layers. ## Programmatic aspects - Use object-oriented programming principles by defining each neural network architecture as a class inheriting from PyTorch's `nn.Module`. - Implement forward propagation methods within each class that define how input data flows through the network layers. - Utilize PyTorch's neural network module (`torch.nn`) functionalities such as `nn.Conv2d`, `nn.BatchNorm2d`, `nn.ReLU`, `nn.Dropout`, `nn.AdaptiveAvgPool2d`, `nn.Linear`, and LSTM cells (`nn.LSTMCell`) where applicable. ## Constants, data and tables - Kernel sizes per layer are `[8x8]`, `[6x6]`, `[5x5]`. - Strides per layer are `[8x8]`, `[6x6]`. - Padding per layer is `[2x2]`, `[2x2]`, `[0]`. - Output channel counts per layer are `[32]`, `[64]`, `[128]`. - Group convolutions per layer are calculated based on input channel count divided by `[16]`, `[32]`, `[64]`. ## Extra details - Ensure that weight initialization standard deviation (`w_init_stddev`) is configurable but defaults to zero if not provided. - Ensure that bias initialization value (`b_init_value`) is configurable but defaults to zero if not provided. - Ensure that weight regularization lambda value (`w_reg_lambda`) is configurable but defaults to zero if not provided. python import torch.nn as nn class ConvNet(nn.Module): def __init__(self, n_out_classes=10): super(ConvNet, self).__init__() self.conv_layers = nn.Sequential( nn.Conv2d(in_channels=..., out_channels=32 // ... , kernel_size=(8, 8), stride=(8,), padding=(2,), groups=..., bias=True), nn.BatchNorm2d(32), nn.ReLU(), nn.Dropout(0), nn.AdaptiveAvgPool2d(output_size=...), nn.Conv2d(in_channels=..., out_channels=64 // ... , kernel_size=(6,), stride=(6,), padding=(2,), groups=..., bias=True), nn.BatchNorm2d(64), nn.ReLU(), nn.Dropout(0), nn.AdaptiveAvgPool2d(output_size=...), nn.Conv2d(in_channels=..., out_channels=128 // ... , kernel_size=(5,), stride=(1,), padding=(0,), groups=..., bias=True), nn.BatchNorm2d(128), nn.ReLU(), nn.Dropout(0), nn.AdaptiveAvgPool2d(output_size=...) ) self.fc_layers = nn.Sequential( nn.Linear(in_features=..., out_features=256), nn.ReLU(), nn.Linear(in_features=256, out_features=n_out_classes) ) def forward(self, x): x = self.conv_layers(x) x = torch.flatten(x, start_dim=1) x = self.fc_layers(x) return x class ConvLSTMNet(nn.Module): def __init__(self): super(ConvLSTMNet,self).__init__() # Define convolutional layers similar to ConvNet self.lstm_cells = [ nn.LSTMCell(input_size=?, hidden_size=?), nn.LSTMCell(input_size=?, hidden_size=?) ] # Initialize hidden states here def forward(self,x,h,c): # Apply convolutions # Flatten output # Pass through LSTM cells return h,c,x # Helper functions for calculating parameters will be needed here # Instantiate networks here if necessary **User:** I'd like you add weight decay regularization options for both networks' weights during training. **Assistant:** Sure! You can add weight decay directly when setting up your optimizer rather than changing anything inside these network definitions themselves since weight decay is typically applied during optimization rather than model definition. Here's how you would modify your training loop setup: python optimizer_convnet = torch.optim.Adam(convnet.parameters(), lr=learning_rate_weight_decay_decay_convnet) optimizer_convlstmnet = torch.optim.Adam(convlstmnet.parameters(), lr=learning_rate_weight_decay_decay_convlstmnet) for param_group in optimizer_convnet.param_groups: param_group['weight_decay'] = weight_decay_value_for_convnet for param_group in optimizer_convlstmnet.param_groups: param_group['weight_decay'] = weight_decay_value_for_convlstmnet # Now continue with your training loop... Remember that you'll need to define variables like `learning_rate_weight_decay_decay_convnet` and `weight_decay_value_for_convnet` according to your needs. **User:** I think adding skip connections could improve our model performance by mitigating vanishing gradients issues. **Assistant:** To add skip connections similar to ResNet blocks between convolutional layers would involve modifying our existing architecture slightly: For example: python class ResidualBlock(nn.Module): def __init__(self,in_channels,out_channels,stride,padding,kernel_size,bias=True,no_bn=False,no_relu=False,no_dropout=False,w_init_stddev=None,b_init_value=None,w_reg_lambda=None): super(ResidualBlock,self).__init__() self.conv_block=self._make_layer(in_channels,out_channels,stride,padding,kernel_size,bias,no_bn,no_relu,no_dropout,w_init_stddev,b_init_value,w_reg_lambda) self.skip_connection=self._make_skip_connection(in_channels,out_channels,stride,padding,kernel_size,bias,no_bn,no_relu,no_dropout,w_init_stddev,b_init_value,w_reg_lambda) def _make_layer(self,in_channels,out_channels,stride,padding,kernel_size,bias,no_bn=False,no_relu=False,no_dropout=False,w_init_stddev=None,b_init_value=None,w_reg_lambda=None): conv_block=[] conv_block.append(nn.Conv(...)) # Add first conv layer parameters here if not no_bn: conv_block.append(nn.BatchNorm(...)) # Add BatchNorm parameters here if not no_relu: conv_block.append(nn.ReLU()) if not no_dropout: conv_block.append(nn.Dropout(...)) # Add Dropout parameters here return nn.Sequential(*conv_block) def _make_skip_connection(self,in_channels,out_channels,stride,padding,kernel_size,bias,no_bn=False): skip_connection=[] if stride != (1,) * len(stride) or in_channels != out_channels: skip_connection.append(nn.Conv(in_channels,out_channels,kernel_size=stride,padding=[s//stride[i]-kernel_sizes[i]+padding[i]+kernel_sizes[i]%stride[i]-padding[i]%stride[i]-kernel_sizes[i]%stride[i]+padding[i]%stride[i]-kernel_sizes[i]+padding[i]*stride[i]-padding[i]%stride[i]+kernel_sizes%stride]) ) if not no_bn : skip_connection.append(nn.BatchNorm(out_channel)) return skip_connection def forward(self,x): residual=x+self.skip_connection(x)+self.conv_block(x) return residual Then you would replace parts of your existing network definition with instances of this new block. **User:** Can we make our network capable of handling variable input image sizes? **Assistant:** To enable variable input image sizes without manual calculation adjustments each time requires replacing fixed-size pooling operations with adaptive ones wherever possible already done using AdaptiveAvgPool before flattening operation before passing data through fully connected/LSTM cells. However full flexibility may require additional architectural changes depending on what exactly "variable" means regarding input shapes - e'taşımıza bağlı olarak ek mimari değişiklikler gerekebilir. For instance: If you're dealing solely with varying spatial dimensions while keeping channel dimension fixed: Ensure every part downstream after convolutions can handle different spatial dimensions - use global average pooling before flattening: Replace: python self.fc_layers = ... nn.Linear( ... ) with: python self.global_avg_pool = ... nn.AdaptiveAvgPool( ... ) and then use: python def forward(self,x): ... x=self.global_avg_pool(x) x=torch.flatten(x,start_dim= ... ) ...
