Grok’s Share and Claude’s Leak: 5 Things We Can Learn From System Prompts

The foundational instructions that govern the operation and user/model interaction of language models (also known as system prompts) are able to offer insights into how we — as users, AI practitioners, and developers — can optimize our interactions, approach future model advancements, and develop useful language model-driven applications.


7 Pandas Tricks for Time-Series Feature Engineering

Feature engineering is one of the most important steps when it comes to building effective machine learning models, and this is no less important when dealing with time-series data.


Time-Series Transformation Toolkit: Feature Engineering for Predictive Analytics

In time series analysis and forecasting , transforming data is often necessary to uncover underlying patterns, stabilize properties like variance, and improve the performance of predictive models.


A Gentle Introduction to Q-Learning

Reinforcement learning is a relatively lesser-known area of artificial intelligence (AI) compared to highly popular subfields today, such as machine learning, deep learning, and natural language processing.


Building a Decoder-Only Transformer Model Like Llama-2 and Llama-3

This post is divided into five parts; they are: • From a Full Transformer to a Decoder-Only Model • Building a Decoder-Only Model • Data Preparation for Self-Supervised Learning • Training the Model • Extensions The transformer model originated as a sequence-to-sequence (seq2seq) model that converts an input sequence into a context vector, which is then used to generate a new sequence.


Building a Transformer Model for Language Translation

This post is divided into six parts;they are: • Why Transformer is Better than Seq2Seq • Data Preparation and Tokenization • Design of a Transformer Model • Building the Transformer Model • Causal Mask and Padding Mask • Training and Evaluation Traditional seq2seq models with recurrent neural networks have two main limitations: • Sequential processing prevents parallelization • Limited ability to capture long-term dependencies since hidden states are overwritten whenever an element is processed The Transformer architecture, introduced in the 2017 paper "Attention is All You Need", overcomes these limitations.


How to Diagnose Why Your Regression Model Fails

In regression models , failure occurs when the model produces inaccurate predictions — that is, when error metrics like MAE or RMSE are high — or when the model, once deployed, fails to generalize well to new data that differs from the examples it was trained or tested on.


Building a Seq2Seq Model with Attention for Language Translation

This post is divided into four parts; they are: • Why Attnetion Matters: Limitations of Basic Seq2Seq Models • Implementing Seq2Seq Model with Attention • Training and Evaluating the Model • Using the Model Traditional seq2seq models use an encoder-decoder architecture where the encoder compresses the input sequence into a single context vector, which the decoder then uses to generate the output sequence.


Image Augmentation Techniques to Boost Your CV Model Performance

Word Embeddings for Tabular Data Feature Engineering

It would be difficult to argue that word embeddings — dense vector representations of words — have not dramatically revolutionized the field of natural language processing (NLP) by quantitatively capturing semantic relationships between words.


Decision Trees Aren’t Just for Tabular Data

Versatile, interpretable, and effective for a variety of use cases, decision trees have been among the most well-established machine learning techniques for decades, widely used for classification and regression tasks.
