✪ Data Structures and Algorithms

Data Structures and Algorithms (DSA) is a foundational concept in computer science that helps in solving problems efficiently. A data structure is a way of organizing and storing data so that it can be accessed and modified efficiently.

1] Linear - Array, Linked List, Stack, Queue    -> Store sequential data
2] Non-linear - Tree, Graph    -> Represent hierarchy or networks
3] Hash-based - Hash Table, Hash Map    -> Fast lookups and insertions
4] Specialized - Heap, Trie, Segment Tree    -> For advanced operations like prefix matching or efficient searching

Linear Non-linear Hash-based Specialized

✅ Examples of Algorithms:

1] Sorting: Bubble Sort, Merge Sort, Quick Sort
2] Searching: Linear Search, Binary Search
3] Recursion: Solving problems by breaking them into subproblems
4] Dynamic Programming: Optimizing recursive problems
5] Greedy Algorithms: Making locally optimal choices
6] Graph Algorithms: BFS, DFS, Dijkstra’s, Kruskal’s

2] Multimodal Input/Output Fusion : Integrating text, image, audio, and video using cross-attention and shared embeddings.
3] Generalist Intelligence & Tool Use : Designing systems that perform multi-domain tasks with reasoning, planning, and memory.
4] Multimodal Architectures (MoE, Flamingo, Gemini, GPT-4o) : Vision-language-audio models using expert routing and joint representations.
5] Constitutional & Ethical Reasoning : Human-aligned learning with ethical filters and safety policies (e.g., Claude, Gemini).
6] Evaluation Benchmarks (MMMU, VQAv2, MMLU, TDI-Eval) : Testing reasoning, factuality, and cross-modal comprehension.
7] Cross-Modal Dialogue & Emotion Understanding : Coherent, emotionally aware responses across speech, text, and images.

Tools & Frameworks for LCMs

1] GPT-4o (OpenAI) : Multimodal unified model handling text, vision, and speech in real time.
2] Gemini (Google DeepMind) : Conceptual agent with tool use, reasoning, and multimodal interaction.
3] Claude (Anthropic) : Constitutional model with safety alignment and cross-modal grounding.
4] Meta SeamlessM4T : Speech-to-speech translation with multilingual and multimodal fusion.
5] Flamingo : Few-shot vision-language model from DeepMind.
6] LLaVA : Visual-Language Assistant (open-source) for VL tasks.
7] Hugging Face Transformers : Library for loading and fine-tuning foundational and multimodal models.
8] LangChain + LlamaIndex : Used for orchestration and RAG-style workflows with LCMs.
