The success of Deepseek explained

Deepseek is an impressive example of smart engineering. In January 2025, DeepSeek, a Chinese startup, shook the AI world by launching a powerful language model that rivaled industry giants like OpenAI and Google. With innovative engineering and cost-effective development, DeepSeek proved that top-tier AI can be built with fewer resources, reshaping the competitive landscape.

In this article I list and explain the concepts of Machine Learning and Artificial Intelligence that were used:

DeepSeek’s popularity is built on a foundation of advanced AI and machine learning (ML) technical concepts. Here’s a comprehensive list of the most relevant technical aspects:

1. Neural Network Architecture

transformer Model – The foundation of DeepSeek’s language models, enabling parallelized training and high performance.

Multi-Head Attention – Improves the ability to capture different aspects of relationships in data.
Feed-Forward Networks (FFN) – Layers in the transformer that help process features extracted by attention layers.

2. Model Optimization Techniques

Model Distillation – Compressing knowledge from larger models into smaller, more efficient ones.
Parameter Efficient Fine-Tuning (PEFT) – Methods like LoRA (Low-Rank Adaptation) reduce memory requirements.
Quantization – Reducing the numerical precision of model parameters to lower computational costs.
Sparse Training & Pruning – Eliminating unnecessary weights to improve efficiency.

3. Training Methodologies

Self-Supervised Learning (SSL) – Training the model with unlabeled data using masked token prediction.
Reinforcement Learning from Human Feedback (RLHF) – Aligning model outputs with human preferences using reinforcement learning.
Contrastive Learning – A technique that enhances representation learning through similarity/dissimilarity comparisons.
Distributed Training – Using multiple GPUs in parallel to accelerate training.
Mixed Precision Training – Reducing computational load by using lower precision formats (e.g., FP16, BF16).

4. Data Processing & Augmentation

Large-Scale Data Curation – Collecting diverse datasets from various sources.
Synthetic Data Generation – Using AI to generate training examples when data is scarce.
Tokenization – Breaking text into smaller units for processing (e.g., byte-pair encoding, WordPiece).
Batch Normalization – Stabilizing learning by normalizing activations across mini-batches.

5. Inference & Deployment

Efficient Inference Engines – Optimizing runtime execution for real-time responses.
Edge AI – Deploying models on low-power devices through optimization.
