# How similar is Adam optimization and Gradient clipping?

According to the Adam optimization update rule: $$m \leftarrow \beta_1 m + (1 - \beta_1)\nabla J(\theta)$$ $$v \leftarrow \beta_2 v + (1 - \beta_2)(\nabla J(\theta) \odot \nabla J(\theta))$$ $$\theta \leftarrow \theta - \alpha \frac{m}{\sqrt{v}}$$

From the equations, it is clear that $$m$$ is accumulated gradient for each $$\theta$$ based on an exponential decay function and $$v$$ is doing a similar thing (kind of) but with the magnitude of the gradient. Then, when we update the parameters $$\theta$$, we divide the accumulated gradient with square root of the accumulated magnitude to only update those parameters largely which haven't been updated much and vice-versa.

In gradient clipping, we do a kind of similar thing by scaling the gradient vector with respect to a threshold. My question is, why do we need gradient clipping to solve the problem of gradient explosion when we can use Adam optimizer to do a controlled search of the space for the minima.

## 2 Answers

Both have a different role and approach. So, I will say both are not comparable.

Gradient Clipping has a simple task to clip the Gradient to a certain threshold. Its job is done as soon as this is achieved, i.e. Gradient is brought to a decent level to avoid the Explosion.
It has no responsibility to see if learning will converge to best possible minima of Loss.

Adam, on the other hand, is an optimizer. It came as an improvement over RMSprop. The improvement was to have the goodness of both, i.e. Momentum and RMSProp (Read this answer)
Adam is expected to help the learning converge towards the minimum loss function when it is going in Valley or Plateau by managing both the Momentum and Coordinate specific Gradient.

Coming back to your question

why do we need gradient clipping to solve the problem of gradient explosion when we can use Adam optimizer to do a controlled search of the space for the minima.

Let's say, in the first iteration, the Model accumulate very large Gradient because of its depth. So, it will take a considerable jump when updating the weight ($$\theta$$) and can land to any random coordinates in the Loss function space.
Adam can definitely provide a brake on the Gradient, but it has few challenges -

• It needs a few iterations to accumulate the $$v$$ to apply the brake.
• But it is very much possible that during these iterations, the point will take any random coordinates in the space. This randomness will also cause all the coordinates to have random Gradients i.e. no relation to the last Gradient.
This will not let Adam do any accumulation and it will have no clue to act in a corrective manner. Everything will happen haphazardly.

Also, keep in mind, exploding Gradient has bidirectional causation, i.e. explosion causes more Gradient, and then this significant Gradient adds more to the Explosion. So, the learning reaches very quickly to NaN state.

As you suggest, the update rule for Adam is based only on the sign, not the magnitude of the gradient. Gradient clipping should not be needed to prevent exploding gradients when using Adam to optimize (though it might still be useful, depending on the circumstance).

# 3상전압을 이용한 중첩방전형 오존발생기의 특성

• Published : 1999.07.19

#### Abstract

In this paper, an ozonizer, which can generate individual and superposed silent discharge, using three-phase voltage has been designed and manufactured. The ozonizer consists of 3 electrodes(Central Electrode, Internal Electrode and External Electrode) and 2 gaps(gap between Central Electrode and Internal Electrode, gap between Internal Electrode and External Electrode). Ozone is generated according to voltage supplying method to each electrode by individual silent discharge and three-phase superposed discharge. The characteristics of ozone generation were investigated with variation of discharge power and the quantity of supplied gas($O_2$). In case of individual silent discharge, the maximum values of ozone concentration, ozone generation and ozone yield were obtained between internal electrode and external electrode, and its values were 2300[ppm], 570[mg/h] and 745[g/kWh] respectively. Each maximum values was 5039[ppm], 1773[mg/h] and 851[g/kWh] respectively, when three-phase superposed silent discharge was employed. Therefore, characteristics of ozone generation with three-phase voltage are improved compared with single-phase voltage because silent discharge is generated continuously.

In terms of regiochemistry, Zaitsev’s rule states that when more than one product can be formed, the more substituted alkene is the major product. As expected, in each case, the amount of product formed increases with time, although eventually a time is reached when there is no net change in the concentration of S or P. Predict the products for reactions occurring at the benzylic position, including oxidation,. (η5-C 5Me5)Ir(PMe3) and Ir(PPh3)3Cl, when heated in cyclohexane, both undergo oxidative addition of a C-H bond, but the products are very different. Managers need information in order to introduce products and services that create value in the mind of the customer. Impossible to grow. A product produced by a single firm that has some unique characteristics compared to similar products of other firms. But, why are so many companies focusing on the customer experience and what happens to companies that choose to ignore it? It wasn't too long ago when every business claimed that the key to winning customers was in the quality of the product or service they deliver. Many reactions are intramolecular. These routines perform elementary tasks, usually for more than one calling subprogram. Meanwhile, some people might be filing more than one claim, and workers whose hours have been cut because of COVID-19 can also seek unemployment benefits. This number can be calculated and is called the theoretical yield. As of early 2014, there were 466 brands and 7764 unique flavors of e-cigarette products.

Which stage of the product life cycle are most products in? When is it over? 20. For logistic regression, sometimes gradient descent will converge to a local minimum (and Since we train one classifier when there are two classes, we train two classifiers when there are three classes (and we do one-vs-all classification). Rearrangements are sometimes seen. Identify the functional group that would be expected to be found in the final product upon completion of the reaction between 1-hexyne and a mixture of mercuric sulfate and aqueous sulfuric acid. In terms of partial-differential calculus, point-price elasticity of demand can be defined as follows:[17] When demand is more inelastic than supply, consumers will bear a greater proportion of the tax. Precipitation reactions take place between ionic compounds in solution. v Substitution is more complicated than it looks! As we've seen, when a 1° or methyl halide reacts with ethoxide ion The relative rates of the possible reactions dictate the outcome of the. When more than one product is expected, predict which will be the major product. Peak plasma concentrations are 40 ng/mL following an i. If one is calculating the yield of a chemical reaction, the equations must be balanced. Based on this activity series, we can make the following predictions: Ag(s) + HCl(aq) no reaction Ag is less active than hydrogen. 37)Provide a series of synthetic steps by which (CH3)2C CH2 could be prepared from 2-methylpropane.

Differrent table manners. 37)Provide a series of synthetic steps by which (CH3)2C CH2 could be prepared from 2-methylpropane. 50 ng/mL to 3. And the reason it does that is because the more substituted carbon is the one that was the more stable carbocation in the mechanism. In an addition, two molecules combine to form one product molecule. As of March 31, 2020, more than 2,200 XPOVIO prescriptions have been filled since launch, and more than 150 new physician prescribing accounts were added in the first quarter. However, for some products, the customer's desire could drop sharply even with a little price The good's elasticity can also be used to predict the incidence (or "burden") of a tax on that good. For reactions in which an aromatic species is converted to a nonaromatic one, the reaction will be unfavorable because the stability of the system decreases. As expected, in each case, the amount of product formed increases with time, although eventually a time is reached when there is no net change in the concentration of S or P. Branched chain reactions are also possible, in which a chain carrier reacts to form more than one chain carrier in a single elementary step. • An electrocyclic ring closure is an intramolecular reaction that forms a cyclic product containing one more ! bond and one fewer " bond than the reactant. Chemical reactions that absorb (or use) energy are called endothermic. Many of them served as army generals and navy admirals, defending Russian borders in different wars and battles. A precipitation reaction is one in which dissolved substances react to form one (or more) solid products. In general, what we call “water”is a solution that is essential to life. Using Accelerated Life Tests Results to Predict Product Field Reliability Abstract Accelerated life tests (ALTs) provide timely assessments of the reliability of materials, components, and subsystems.
