What exactly are Neural Networks?
Basic Concept:
Mimic the Brain: Neural networks are computing systems vaguely inspired by the biological neural networks in human brains.
Neurons: They consist of interconnected units or nodes (analogous to biological neurons) that process information using a connectionist approach.
Structure:
Layers: Typically organized in layers (input layer, one or more hidden layers, and an output layer).
Connections: Each connection, like the synapses in a biological brain, can transmit a signal from one neuron to another.
Weights: Each neuron's output is computed using a weighted sum of its inputs, followed by a non-linear function.
Types of Neural Networks:
Feedforward Neural Networks: The simplest type where the connections between the nodes do not form a cycle.
Convolutional Neural Networks (CNNs): Primarily used in image recognition and processing, these networks employ a mathematical operation called convolution.
Recurrent Neural Networks (RNNs): Suitable for sequence data like time series or natural language, with connections forming cycles.
Deep Neural Networks: Neural networks with multiple hidden layers, capable of learning complex patterns.
Learning Process:
Training: Involves adjusting the weights of the connections based on the error of the output compared to the expected result.
Backpropagation: A common method used for training, especially in deep learning, where the error is propagated back through the network to adjust the weights.
Activation Functions: Functions like Sigmoid, ReLU (Rectified Linear Unit), and Tanh that help the network learn complex patterns.
Applications:
Image and Speech Recognition: Exceptional performance in recognizing patterns in images and audio.
Natural Language Processing: Used in understanding and generating human language.
Predictive Analytics: Forecasting trends and patterns in data.
Autonomous Systems: Empowering self-driving cars, drones, and other autonomous systems.
Challenges:
Requires Large Datasets: Generally, the more data available, the better a neural network can learn.
Computationally Intensive: Training can require significant computational resources, especially for deep learning models.
Interpretability: Often referred to as "black boxes" because understanding the internal workings and decision-making can be challenging.
What is the difference between neural networks and deep learning? How would they be structured regarding each other?
What are limitations of GenAI models?
Understanding context: While generative AI models like GPT-3 can create grammatically correct and contextually relevant responses, they don't truly "understand" the text in the way humans do. They are essentially pattern-matching algorithms hat have learned to predict, based on the data they were trained on, what comes next in a sequence of text.
Lack of common sense: Because generative AI models learn from data, they don't possess innate human knowledge or common sense unless it was present in those training data. For example, AI models might not inherently understand that an elephant cannot fit inside a car, unless they've seen similar information in the data they were trained on.
Dependence on training data: The quality and scope of the training data greatly affect the performance of generative AI models. If the training data are biased, the model's output will likely also be biased. Similarly, if the training data lack certain information, the model won't be able to generate that information accurately.
Control and safety: It can be challenging to control the output of generative models. They might create content that is inappropriate, offensive, or misleading. This is a significant area of ongoing research in AI safety.
Resource intensive: Training generative AI models typically requires a lot of computational resources and data, making it inaccessible for individual researchers or small organizations.
Inability to verify facts: Generative models like GPT-3 don't have the ability to access real-time or current information and can't verify the truth of the information they generate; they can only draw on the knowledge that was available up until the point they were last trained. Applications on top of the models are being developed to perform web searches to look up facts.
Hallucination: The term comes from the idea that the model is "imagining" or "making up" details that were not in the input and do not accurately reflect reality. Hallucination can be a major issue in tasks where factual accuracy is important, such as news generation or question answering.
