The Dupire equation has since become a standard tool in the industry and has been used to price trillions of dollars of options over the years. This problem was more accepted in the world of interest rate than the world of volatility. The principle is very simple: Regularities such as performance of strategies according to the market regime can be observed, but there is no guarantee of their persistence.
My own involvement with AI predates my last 30 years in finance. You mentioned the advent and large-scale uptake of machine learning and big data as key developments that have the potential of upending the industry.
Whether it be in derivative product design or in asset allocation, it seems that the needs of the individual agents are somewhat disregarded. The concept of volatility being more elusive than the interest rate and the options having been created after the bonds, it is natural that the concept of forward volatility variance actually has appeared well beyond that of forward rates.
He is probably best known for his ground breaking research in derivative pricing, having shown how to derive a local volatility model consistent with a surface of option prices across strikes and maturities — establishing the so-called Dupire’s approach to local volatility for modelling the volatility smile.

In summary, the local volatility model has its limitations but the concept of local volatility itself is not inevitable and disregarding it, is to condemn oneself to not understand the mechanisms underlying volatility. So if the market systematically deviates from local volatilities, it is possible to set up an arbitrage strategy.
Well, for quants in the middle of Manhattan crowded with traffic and people the solution was stationary racing cars packed with technology and sensors connected to a large wall sized screen. Criticizing local volatility means criticize the instantaneous forward rate, which was a major advance in forward interest rates. The local volatility vruno, it postulates that the instantaneous volatility follows exactly the local volatility extracted from option prices, thus equal to a duprie function of time and money.
Examples of alternative data are text, satellite images, supply chain, Environmental, Social, and Governance ESGvessel routes, credit cards, geolocation data, etc. You keep working on the volatility and correlation, can we consider these two parameters as assets in its own right?

It was therefore natural to try to unify these two models to elaborate a stochastic volatility model calibrated to the surface. He pioneered the use of neural networks in finance and is probably best known for his work on local volatility models.

In the business side, we can expect an expansion of securitization to a wide variety of dkpire if you want a French example: AmazonGlobal Ship Orders Internationally.
Assuming that the basket options or spreads with different coefficients are available, it is possible to block the unconditional instantaneous variance, but not the conditional, and only for a normal distribution of the covariance absolute and not btuno log-normal distribution proportional.
It is important to distinguish the concept of local volatility from the local volatility model. The mathematician is interested primarily in price, calculated as the expectation on the scenarios generated by the model, while the trader requires not just an average, but a guaranteed result regardless of the realized scenario.

This page was last edited on 31 Augustat I presented in A Unified Theory of Volatilitywhich provides among others things that the local variances square of the local volatilities are synthesizable from the vanillas and a stochastic volatility is calibrated to the surface if and only if the instantaneous variance expected, conditional on a price level, equal to the local variance bruon by the surface.
Are you an author? My paper Pricing and Hedging with Smiles was presented in June with a version in risk Magazine of ” Pricing with a smile” published in January Local volatilities reveal information about the future behavior of volatility from vanilla option prices today, regardless of the model considered.
