Analytics Random Cut Forest (RCF) Analytics Random Cut Forest (RCF) is an unsupervised machine learning algorithm that is used for anomaly detection. In RCF, each tree is constructed by randomly selecting a subset of features and then randomly selecting a subset of data points from the training dataset. This process helps to ensure that the trees are more diverse and less correlated, which makes them more effective at detecting anomalies....
Horovod Distributed Training Framework Horovod is a distributed training framework for TensorFlow, Keras, PyTorch, and Apache MXNet. It is designed to make distributed training easy and efficient. Horovod uses a ring-based communication pattern to efficiently distribute data across multiple GPUs or machines. This can significantly improve the training speed of deep learning models. Horovod is also designed to be easy to use. It can be used with existing TensorFlow, Keras, PyTorch, and Apache MXNet code with minimal changes....
What are the reasons to use machine learning? An example of a business problem where the use of ML would be appropriate is generating personalized recommendations. In this case, the solution to the problem requires complex logic, and we would want to provide personalized recommendations at scale with quick turnaround times. Requires complex logic Since developing personalized recommendations requires complex logic, ML is an appropriate tool to consider. Requires scalability Serving millions of requests for personalized recommendations every second is a challenge....
Methods to prevent overfitting in Machine Laerning L2 Regularization (Ridge Regression) L2 regularization adds a penalty term to the loss function based on the squared magnitudes of the model’s weights. This penalty discourages large weight values and encourages the model to use smaller weights, leading to a smoother and more generalized solution. The regularization term is controlled by a hyperparameter (lambda or alpha) that balances the trade-off between fitting the training data and keeping the weights small....
Major Use Case for an RNN (Recurrent Neural Network): Sequential data processing, where the order of data elements matters. RNNs are designed to handle sequences of data, such as time series data, natural language text, speech, music, and more. The main strength of RNNs lies in their ability to capture temporal dependencies and patterns in sequential data. Example Use Cases for RNNs: Natural Language Processing (NLP): RNNs are commonly used in tasks like text generation, machine translation, sentiment analysis, named entity recognition, and language modeling....
