Bayesian inference

Bayesian inference ( BAY-zee-ən or BAY-zhən) is a method of statistical inference in which Bayes' theorem is used to calculate a probability of a hypothesis, given prior evidence, and update it as more information becomes available. Fundamentally, Bayesian inference uses a prior distribution to estimate posterior probabilities. Bayesian inference is an important technique in statistics, and especially in mathematical statistics. Bayesian updating is particularly important in the dynamic analysis of a sequence of data. Bayesian inference has found application in a wide range of activities, including science, engineering, philosophy, medicine, sport, and law. In the philosophy of decision theory, Bayesian inference is closely related to subjective probability, often called "Bayesian probability".

• AI Chips Explained: Training vs. Inference Processors Unveiled

  When an AI model is ready to face the world, inference chips take the stage. These chips are optimized for speed and efficiency, executing pre-trained models to make real-time decisions based on new data. Unlike their training-focused counterparts, inference chips must balance computational power with energy efficiency, enabling their integration into power-sensitive devices like smartphones and IoT gadgets. Google's Edge TPU and NVIDIA's Jetson series exemplify this balance, ensuring AI [...] Though both types of chips are pillars of the AI ecosystem, they cater to different needs. Training chips are computational powerhouses, built for the complex tasks of model development. Inference chips, however, are designed for operational efficiency, ensuring the smooth deployment of AI in real-world scenarios. This divergence in focus reflects their unique roles: training chips process large datasets to build the model, while inference chips efficiently execute these models, delivering [...] The considerations of energy consumption and cost further differentiate training and inference chips. Training chips, due to their intensive computational demands, are power-hungry and costly. Conversely, inference chips aim for cost-efficiency and energy savings, making AI deployment scalable and practical for various applications. This balance of performance, cost, and energy efficiency is vital for the widespread adoption of AI technologies, making them accessible and functional across a

NVIDIA H200 [...] AI inference is happening everywhere, and it’s growing fast. Think of AI inference as the moment when a trained AI model makes a prediction or decision. For example, when a chatbot answers your question or a self-driving car spots a pedestrian. This explosion in real-time AI applications is creating huge demand for specialized chips. These chips must deliver three key things: blazing speed to handle requests instantly, energy efficiency to save power and costs, and affordability to scale

• A Deep Dive on Inference Semiconductors - by Eric Flaningam

  Inference, on the other hand, is a simper workflow built around matrix multiplications. At a circuit level, this means inference semiconductors need a lot of multiplication and addition capability (fused multiply-add circuits, for example). Many inference chip approaches cut out control logic (parts of the semiconductor that give instructions to the circuits) to maximize the amount of these circuits. Meaning that they’re much less flexible but much more capable for inference. [...] In reality, Nvidia has a near monopoly on training, so most of these chips are targeting the inference market. Dylan Patel shared that Nvidia has approximately 97% market share if we remove Google’s TPUs from the equation (70% market share with TPUs). The majority of the remaining 3% comes mostly from AMD’s revenues. This is fairly consistent with estimates reported by Next Platform last year. [...] In summary, GPUs are more powerful, have more memory, and are more complex. Inference chips cut out the “unnecessary stuff” to be as efficient as possible. In theory, the TCO should be better for inference-specific semiconductors. 2. The Inference Semiconductor Landscape ---------------------------------------- Now that we have the theory in place, let’s discuss, at a high level, the various approaches companies are taking in this space.
