What are the different fine tuning techniques used in LLM

Fine-tuning techniques in Large Language Models (LLMs) play a crucial role in adapting these models to specific tasks or domains. Here are some common fine-tuning techniques used in LLMs:

  1. Domain-Specific Fine-Tuning: Fine-tuning the LLM on a domain-specific dataset. This helps the model better understand and generate text related to a particular field, such as finance, healthcare, or legal.


  2. Task-Specific Fine-Tuning: Adapting the LLM to perform a specific NLP task, such as text classification, sentiment analysis, named entity recognition, or machine translation. The model is fine-tuned on task-specific data.


  3. Transfer Learning: Leveraging pre-trained LLMs to transfer knowledge from one task or domain to another. This approach reduces the amount of data and training time required for the new task.


  4. Prompt Engineering: Designing effective prompts or input patterns to guide the LLM's output. This is commonly used in question-answering systems and chatbots to control the generated responses.


  5. Multi-Task Learning: Fine-tuning the LLM on multiple tasks simultaneously. This helps the model become more versatile and capable of handling a range of NLP tasks.


  6. Knowledge Distillation: Transferring knowledge from a larger, more complex LLM to a smaller model (student) to reduce computational resources while maintaining performance.


  7. Adversarial Fine-Tuning: Incorporating adversarial training techniques, such as Generative Adversarial Networks (GANs), to fine-tune LLMs for tasks like text generation, style transfer, or image captioning.


  8. Hyperparameter Tuning: Adjusting hyperparameters like learning rates, batch sizes, and dropout rates to optimize the LLM's performance during fine-tuning.


  9. Controlled Generation: Implementing control mechanisms to steer the LLM's output, ensuring it adheres to specific guidelines, styles, or content restrictions.


  10. Layer-Specific Fine-Tuning: Focusing fine-tuning efforts on specific layers or components of the LLM to tailor its behavior for specific tasks.


  11. Regularization Techniques: Applying regularization methods, such as L1 or L2 regularization, to prevent overfitting during fine-tuning.


  12. Data Augmentation: Increasing the diversity of training data through data augmentation techniques to improve the LLM's generalization.


  13. Early Stopping: Monitoring the LLM's performance during training and stopping when it reaches a plateau or starts overfitting.


  14. Continuous Learning: Continuously fine-tuning LLMs with new data to adapt to changing patterns and requirements.


  15. Curriculum Learning: Training LLMs on a curriculum of progressively challenging tasks or data to facilitate learning and enhance performance.

These fine-tuning techniques are essential for tailoring LLMs to specific applications, improving their performance, and ensuring they generate high-quality outputs for various natural language processing tasks. The choice of technique depends on the use case and the desired outcomes.

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.
