tnsa 7.3.2

A transformer model with advanced features for casual language modeling.

TNSA Curiosity

TNSA Stable Curiosity is a transformer-based model architecture designed for casual language modeling tasks. It is an enhancement of the ARCH-X9 and NGen2 model, optimized for various NLP tasks such as text classification, token classification, and language generation. The architecture features advanced mechanisms like gradient checkpointing, making it more efficient and scalable.

Installation

To install tnsa, you can use pip from PyPI:

pip install tnsa 

How to use Curiosity OpenModel Architecture(Based on ARCH-X 9)

from tnsa.stable.curiosity import TNSAforCasualLM

# Initialize the model
model = TNSAforCasualLM(
    hidden_size=768,
    num_hidden_layers=12,
    num_attention_heads=12,
    intermediate_size=3072,
    intermediate_act_fn='gelu',  # Can also use other activations like 'relu'
    hidden_dropout_prob=0.1,
    attention_probs_dropout_prob=0.1,
    initializer_range=0.02,
)

# Example input
input_tensor = ...  # Your input tensor here, with shape [batch_size, seq_length, hidden_size]
attention_mask = ...  # Your attention mask tensor here

# Forward pass through the model
output = model(input_tensor=input_tensor, attention_mask=attention_mask)

print(output)

#Instialize you training loop you can keep the parameters to default to re-create NGen2-Nano Base on OpenWEB

Key Parameters

hidden_size: The size of the hidden layers. Defaults to 768 (same as BERT's base).

num_hidden_layers: The number of transformer layers. Defaults to 12.

num_attention_heads: The number of attention heads in each layer. Defaults to 12.

intermediate_size: The size of the intermediate (feedforward) layer. Defaults to 3072.

intermediate_act_fn: The activation function to use in the intermediate layer. Default is gelu.

hidden_dropout_prob: Dropout probability for hidden layers. Default is 0.1.

attention_probs_dropout_prob: Dropout probability for attention layers. Default is 0.1.

initializer_range: The standard deviation of the initializer. Default is 0.02.

use_gradient_checkpointing: A boolean flag to enable or disable gradient checkpointing for memory efficiency. Default is False.

How Curiosity OpenModelArchitecture Differs from ARCH-X 9(Closed Source)

The Curiosity architecture is based on the standard transformer architecture used in NGen2, with the following enhancements:

Gradient Checkpointing: An optional feature to enable gradient checkpointing, allowing for more efficient memory usage during training. This is particularly useful when working with large models.

Improved Attention Mechanism: The attention mechanism has been fine-tuned for better handling of long-range dependencies and more accurate attention distributions.

Optimized Architecture: Custom improvements to layer normalization and dropout mechanisms help improve the model’s performance on various NLP tasks.

Model Performance

While Curiosity is similar to NGen2, it has been fine-tuned to outperform NGen2 in some language modeling tasks by using a more efficient memory usage pattern, which makes it better suited for tasks with large datasets or longer sequences.
