What are techniques to reduce Overfitting?

 

MethodDescription
More DataIncrease the size of the training dataset.
Cross-ValidationAssess the model's performance using k-fold cross-validation.
Feature SelectionCarefully choose relevant features and exclude irrelevant ones.
Feature EngineeringEngineer meaningful features that capture essential information.
Simpler ModelsOpt for simpler models with fewer parameters when possible.
RegularizationApply L1 or L2 regularization to penalize large parameter values.
DropoutIn neural networks, randomly set a fraction of neurons to zero during training.
Early StoppingMonitor validation performance and stop training when it degrades.
Ensemble LearningUse ensemble methods like random forests or gradient boosting.
Pruning (Decision Trees)Remove branches that do not significantly contribute to predictive power.
Cross-Feature ValidationValidate models on data from a different time period.
Data AugmentationApply random transformations to increase the effective dataset size.
Bayesian MethodsUse Bayesian techniques for modeling uncertainty.
Domain KnowledgeIncorporate domain expertise into feature selection and model design.
Regularly Validate and Update ModelsContinuously monitor and retrain models with new data or updated features.

What is Tensor Parallelism and relationship between Buffer and GPU

  Tensor Parallelism in GPU Tensor parallelism is a technique used to distribute the computation of large tensor operations across multiple GPUs or multiple cores within a GPU .   It is an essential method for improving the performance and scalability of deep learning models, particularly when dealing with very large models that cannot fit into the memory of a single GPU. Key Concepts Tensor Operations : Tensors are multidimensional arrays used extensively in deep learning. Common tensor operations include matrix multiplication, convolution, and element-wise operations. Parallelism : Parallelism involves dividing a task into smaller sub-tasks that can be executed simultaneously. This approach leverages the parallel processing capabilities of GPUs to speed up computations. How Tensor Parallelism Works Splitting Tensors : The core idea of tensor parallelism is to split large tensors into smaller chunks that can be processed in parallel. Each chunk is assigned to a different GP...

Data Wrangling vs EDA

  Aspect Data Wrangling (Data Preprocessing) Exploratory Data Analysis (EDA) Objective Prepare raw data for modeling by cleaning, transforming, and formatting it appropriately. Explore and understand the data to gain insights, identify patterns, and make decisions on data handling and modeling. Order Typically performed as a preliminary step before EDA. Usually conducted after data wrangling to further investigate data characteristics. Data Handling Focuses on data cleaning, filling missing values, encoding categorical variables, and scaling features. Involves data visualization, statistical analysis, and summary statistics to uncover patterns, relationships, and anomalies. Techniques Techniques include imputation, outlier detection, feature scaling, and one-hot encoding. Techniques include histograms, scatter plots, box plots, correlation matrices, and descriptive statistics. Data Transformation Involves structural changes to the dataset, such as feature engineering, data normaliz...

What's replicated, what's not?

Logged operations are replicated. These include, but are not limited to: DDL DML Create/alter table space Create/alter storage group Create/alter buffer pool XML data. Logged LOBs Not logged operations are not replicated. These include, but are not limited to: Database configuration parameters (this allows primary and standby databases to be configured differently). "Not logged initially" tables Not logged LOBs UDF (User Defined Function) libraries. UDF DDL is replicated. But the libraries used by UDF (such as C or Java libraries)  are not replicated, because they are not stored in the database. Users must manually copy the libraries to the standby. Note: You can use database configuration parameter  BLOCKNONLOGGED  to block not logged operations on the primary.
