Can we get robots to follow language directions without any data that has both nav trajectories and language? In LM-Nav, we use large pretrained language models, language-vision models, and (non-lang) navigation models to enable this in zero shot!
https://t.co/EVsFOj1JhS
Thread:

LM-Nav first uses a pretrained language model (LLM) to extract navigational landmarks from the directions. It uses a large pretrained navigation model (VNM) to build a graph from previously seen landmarks, describing what can be reached from what. Then...

It uses a vision-language model (VLM, CLIP in our case) to figure out which landmarks extracted from the directions by the LLM correspond to which images in the graph, and then queries the VNM to determine the robot controls to navigate to these landmarks.

The results in fully end-to-end image-based autonomous navigation directly from user language instructions. All components are large pretrained models, without hand-engineered localization or mapping systems. See example paths below.

LM-Nav uses the ViKiNG Vision-Navigation Model (VNM): https://t.co/oR1bplIvMt
This enables image-based navigation from raw images.

If you want to play with LM-Nav in the browser, check out the colab demo here: https://t.co/GKrOr24hU6

Of course, our colab won't make a robot materialize and drive around, but you can play with the graph and the LLM+LVM components 😉

Margatha Natarajar murthi - Uthirakosamangai temple near Ramanathapuram,TN
#ArudraDarisanam
Unique Natarajar made of emerlad is abt 6 feet tall.

Sri Gurubhyo Namah.
Some tweets on Adi Shankaracharya and in particular the Guru Parampara of @sringerimath. [I had done this series earlier 5 years ago on account of Shishya Sweekaram].

Adi Shankara established the Sringeri Peetham as the 1st of 4 amnaaya peetams.

The four being
1. Sarada Peetam at Sringeri.
2. Govardhana Peetam at Puri
3. Kalika at Dwaraka
4. Jyothir at Badarikashramam.

He installed his 4 most prominent shishyas as heads of the peetams.

Sureshwaracharya was assigned to Sringeri as its head.

Sringeri is a corruption of Rshyashrunga giri.

Rshyashrunga maharshi [and his father Sri Vibandhaka Maharshi] did their tapas at this place.

It is at Sringeri that Shankara spent 12 of His precious 32 years!!

That gives you and idea how much He loved this place.

Rshyashruga maharshi had a horn on his forehead, a result of being born to a deer. His mere presence was enough to shower rains!!

Rshyashrunga was one who led Putrakamesthi Yaagam of Dasaratha Maharaj and which resulted in Sri Rama's birth!!

1. #Qanon told us that Saudi Arabia is a central piece of the puzzle in taking out the Deep State...we are watching the Deep State attempt to remove Crown Prince MBS and disrupt Pres Trump's administration's ties with MBS and the "new" Saudi/US coalition. Early in his admin,

2....@Potus sent Jared Kushner (JK) to SA on an undisclosed trip and told King Salman that business as usual was over, and if he wanted Pres Trump's support, Prince Alwaleed would have to be divested of $ and power; Alwaleed is one of top Deep State $ men and was tied to HRC.

3. @Potus knew that before he could begin cleansing the US and the rest of the world of the DS, he would have to cut one of the financial head's off the snake (Alwaleed). After JK met w/ King Salman, Alwaleed was arrested and divested of billions; MBS became leader of SA.

4. SA loves Pres Trump because he's a man of his word; SA could not trust Hussein or Clintons because they use SA for oil and leverage; SA has many factions, but essentially you have the new and upcoming SA that is attempting to modernize through Crown Prince MBS, and then you

5...have the old guard represented by Alwaleed who was one of the Deep State financial heads and loyal to the DS more than SA; SA knew Hussein was financing Iran to hold western world hostage, and SA was caught in middle of Deep State black mail; this is why @Potus was celebrated

1/x Fort Detrick History
Mr. Patrick, one of the chief scientists at the Army Biological Warfare Laboratories at Fort Detrick in Frederick, Md., held five classified US patents for the process of weaponizing anthrax.

2/x
Under Mr. Patrick’s direction, scientists at Fort Detrick developed a tularemia agent that, if disseminated by airplane, could cause casualties & sickness over 1000s mi². In a 10,000 mi² range, it had 90% casualty rate & 50% fatality rate

3/x His team explored Q fever, plague, & Venezuelan equine encephalitis, testing more than 20 anthrax strains to discern most lethal variety. Fort Detrick scientists used aerosol spray systems inside fountain pens, walking sticks, light bulbs, & even in 1953 Mercury exhaust pipes

4/x After retiring in 1986, Mr. Patrick remained one of the world’s foremost specialists on biological warfare & was a consultant to the CIA, FBI, & US military. He debriefed Soviet defector Ken Alibek, the deputy chief of the Soviet biowarfare program

5/x Back in Time
In 1949 the Army created a small team of chemists at "Camp Detrick" called Special Operations Division. Its assignment was to find military uses for toxic bacteria. The coercive use of toxins was a new field, which fascinated Allen Dulles, later head of the CIA

STORY OF PURANAS AND SUB PURANA (उप पुराण).

We have already gone through the series on importance & characteristics of all the eighteen Purans. We also know that originally there were hundred crore shlokas but were divided by Vyas in each Kalp and was compiled as eighteen Purans

for the common people to understand it properly and now their total is about four lakhs.

In Brahm Puran, Brahma preached this to Marichi. So this Puran of ten thousand shlokas is called Brahm Puran.

In Padma Puran, the base of the story is the appearance of Brahma on a lotus(Padm) from Vishnu' s navel.This has fifty five thousand shlokas.

Vishnu Puran is primarily based in Varah kalp. This book is on Vishnu and this book has twenty three thousand shlokas.

Vaayu Puran is written in Shwet Kalp and has twenty four thousand shlokas. Here Vayudev preaches about Dharma.

In Bhagwat Puran, which is written with the base of Gayatri mantra describes Dharma extensively. It has 18000 shlokas. It also mentions the story of Vritrasur.

In Narad Puran, which has twenty five thousand shlokas, is a sermon on Dharma by Narad based in Brihad Kalp.

Markandeya Puran has nine thousand shlokas and here it is through the birds that Dharma is described.

How to sell option?
Here let me explain through simple math.
Say BN at 30000
30000 straddle trading at combine premium 800 ( based on current volatility)
Put at 400
Call at 400
You don’t know direction. Sold both.

If move will not come than both will decrease gradually.

At day end it will come down to 720-740 if move will not come. Difference is your profit.

Now case 2:
Move started.
At one points combine premium will start increasing.
Say 810.
Exit immediately. No need to do adjustment.
Let market settle.

Sell again straddle once market settle.
Now repeat same thing.

Straddle selling webinar over.
Good luck.

One can keep SL 550 for both strike to escape from sudden movement.

Here is the detailed information of about strategy,

Entry time : 9.30 - 10
Exit : Upto you

Strategy :
Sell weekly ATM CE & PE at almost equal price
For ex : Sell Nifty 17250 CE at 50 and Nifty 17250 PE at 48 so it will become short straddle

Buy monthly ATM or near ATM CE & PE at matching price (5-10 points diff should be fine) as hedge
For ex : Buy Nifty 17250 CE at 150 and Nifty 17300 PE at 155 so it will become long straddle.

Weekly Short straddle + Monthly Long straddle

Adjustment:

• If you feel slightly bullish/bearish then no adjustment needed
• If Nifty moves 50 up or down and sustain then just simply roll up or down half of qnty and keep rest of the quantity. If market goes up or down further then roll up or down rest.

• If Nifty moves one side or about to breach BEP then add equal amount of lot. This can balance tested side. For ex: If I bought 17300 CE 4 lot as hedge then add 4 lot so you will have only one side risk . Note: Remember to keep SL at cost price (only for additional lot bought)

Capital requirement:
2.2 L for 4 lot
Adjustment requires additional capital upto 1L

Note : High risk high reward strategy, please don’t execute until you fully understand. Kindly do paper trading or backtest.
RR : 1:1
POP : 45-55%

You want to buy a house.

You take a loan from the bank.

The bank asks you, “what if you don’t pay back?”

You say, “take my home and sell it”.

(Thread)

That makes sense. The bank gives you a loan and in case you don’t pay, the bank will take over your house and sell it and recover its money.

That’s collateral.

Banks also lend money to big corporations. With them, banks don’t always have collateral.

So a loan where the bank has collateral is considered safer for the bank.

In the early 2000s, the banks in the USA were giving out loans to people for buying houses.

The economy had just recovered from the tech bubble in 2000 where many banks had given out loans to businesses that had shut down.

In that backdrop, the banks found giving home loans safer.
