Yes I already said that in another comment. But to say no instincts translate to basic Survival, or are more common in mammals would be wrong. Even more so if we start looking at specific classifications, youll obviously start seeing more in common. I never state which instincts I thought humans had. But to say any of our instincts don’t have a commonality with at least one other animal species would be wrong.

Let me see if I understand this. To piggy back off your example, the x axis can be the weight(lbs) of a dog from least to greatest and y axis can be the amount of food the dogs ate also in lbs and from least to greatest. Based on the data we plotted we draw a line that best fits the graph and that line can help estimate solutions? So if we have enough data and a customer comes with a X size dog asking how much their dog needs to eat, we can refer to the line and figure that out. Is this correct?

There’s two types of “hot” just like there are two types of “cold”

How cold is the absolute or “actual” temperature but then they add in the wind chill factor because air moving over you cools you down quicker (or warms you up quicker but the difference in your body temp vs cold is greater than your body temp versus hot)

Now to see how hot it is there is again the actual temp and then what they call the “wet bulb thermometer test”. So they take two thermometers, one they wet a cloth that slips over the bulb of one of them and then basically whirl it a bit to see how much the water evaporates off the one to cool it down. This is how they see hot “hot” it feels. Your body cools off by sweating so the more humidity the harder to cool down and why you get soaked in sweat on humid days but dry as can be in the desert even if the actual temp is hotter.

Most modern CPUs can do exactly what you are stating, as they have the graphical processing capability right on the chip itself. This is enough for most office or school computers, as well as low powered laptops. Generally, GPUs are needed for more difficult tasks that are beyond the capabilities of what a CPU can handle. For example, a very detailed game or computer graphical design will almost require a separate GPU in the PC. However, there are some CPU models that lack the "graphics chips" or are there but disabled by the manufacturer, generally a cheaper model of a CPU.

​

With that being said, if someone was building a budget PC, with very light gaming, you can just get a modern CPU capable of onboard graphics for low end performance.

​

Although I feel like your question may be as to why a CPU itself would need *any form* of a graphics unit, even if it is "on the chip" as with many modern CPUs. The CPU, strictly speaking, does computations in and of itself, at a very fast rate. However, it does not have the ability to do the output frequency conversions needed for standards that make the PC capable of connecting to an HDMI, VGA, Displayport etc. It is the same notion that necessitates having system ram, a hard disk, and other peripherals attached to do what you want to do.

Unfortunately I have no help for the deep learning part, but I'll give a go on linear regression:
Linear regression is using one or more variables to predict a response. The way that it is predicted is with a line (hence the linear name). For example, if you wanted to predict how much food your dog ate, you could use linear regression. Let's say that the response is the total amount of food that your dog eats in a week, and the variable is how much the dog weighs. Knowing that a bigger dog should eat more, there will be a trend towards higher values as the dog weighs more. If you pooled 100 pet owners and asked the weight of their dog and how much the dog eats, you can put all of that data together and use a regression model to predict how much a dog of a specific weight might eat. The data can produce a line of best fit with modeling technology which basically makes the best line that minimizes the differences between the sample data and the predicted data (the line). You can also have more variables than one, such as the dog's eating habits (more or less meals a day), how much the dog exercises, or even the breed (which would be categorical, not numerical).

TL;DR: a linear regression model predicts one value based on another value and then fits a line to it that predicts the value as accurately as it can with the data given.

No, it's not true at all. You are taxed on income, not the increase in wealth. I can have my wealth plummet due to a stock market drop, but owe taxes on my interest income even as my wealth drops. I can go into debt on my $100K income so my wealth is negative, but I still owe taxes on the $100K. Wealth has nothing to do with it except maybe if I die with more than 11 million, and then it is the change of ownership that is taxed--a kind of transaction.

You have a misunderstanding of temperature. Temperature is different than humidity and that is also different from heat loss.

To start backwards, when you are sitting at a window and the weather is cold outside, when you feel , "the cold" at the window you are actually feeling not the cold air coming in, you are experiencing heat loss from your body.

When you stick a thermometer outside it senses the air temperature and it reaches a state when the liquid inside the bulb is the same as the outside air temperature. There is no heat exchange taking place as they are in equilibrium. Unlike your body which generates heat and you will continue to feel the heat loss just like at the window.

Humidity is a measurement of the air to carry water vapor without it returning to a liquid state. It is expressed as a percentage where the current water load of the air is compared to the maximum capacity.

Capacity goes up as a function of temperature. That is why the cold months seem dryer.

I hope that helps you to understand.

I don't think there are any stone fruit that have seedless varieties. Cherry, avocado, peach, etc. Seedless watermelon they create a hybrid of two different watermelon. Like a mule, these hybrids are sterile and only have malformed seeds if any. Pluots are a hybrid and you'll notice that they still have a stone... but sometimes it's only half there or not properly formed. Even seedless oranges can have the odd seed. How they make something seedless depends on how the fruit reproduces and sometimes sterility doesn't yield the desired results if creating sterile fruit is even a realistic process.

Bananas aren't seedless, nor strawberries (I know they're not actually the seeds), nor raspberries... most berries if not all don't have seedless varieties. Some fruit has seedless varieties but the vast majority of the fruit we cultivate isn't seedless.

We *don't* measure the temperature excluding humidity. We just measure the temperature. It's really easy. Temperature doesn't change with humidity.

What changes is how hot it *feels*...when the air is dry sweating works better and we feel cooler. When the air is humid sweating works badly and we feel hotter. But the actual temperature isn't changing.
