विविध न्यूरल नेटवर्क आर्किटेक्चर विविध डेटा आणि कार्यांसाठी योग्य आहेत — CNNs प्रतिमांसाठी, RNNs अनुक्रमांसाठी, आणि transformers भाषेसाठी (आणि वाढत्या प्रमाणात सर्वकाही). मुख्य प्रकार समजून घेणे AI विविध समस्या कशी हाताळते हे स्पष्ट करते.
मुख्य आर्किटेक्चर
CNN (Convolutional Neural Network) → for IMAGES/spatial data:
→ uses convolutions to detect local features (edges, shapes) hierarchically
→ for: image classification, object detection, computer vision
RNN (Recurrent Neural Network) → for SEQUENCES/time-series:
→ processes sequences step by step, maintaining a 'memory' of previous inputs
→ for: text, time-series, speech (older approach; LSTM/GRU variants)
⚠️ struggles with long sequences; largely SUPERSEDED by transformers for language
TRANSFORMER → for SEQUENCES (language) and increasingly everything:
→ attention mechanism; parallel; the dominant modern architecture (LLMs)
→ for: language (LLMs), and now vision, audio, multimodal
